Title: Head torch opinions
Post by: Keris82 on May 08, 2019, 05:29:04 pm
I know this is a common topic but I want some opinions please.

I had to return my fenix HL55 recently because the contacts got loose and the torch stopped working - bad design flaw!  :(

I have been looking at buying a black diamond revolt lamp. Has anyone got one and how do you find it? I have a backup black diamond storm torch which is ok but it's not totally waterproof so may not be suitable for very wet caving. Also the light it gives is more of a spot than giving a wide beam. I wonder if the Revolt is the same?  :-\

I've seen a petzl ultra vario on inglesport. Has anyone got one?

The revolt is a nice headtorch, but for me it's a camping/walking torch rather than a caving headtorch. It doesn't have an incredibly robust feel due to its size and plastic construction, and whilst it's bright enough the AAA batteries that it uses really lets it down on runtime. If you want to go with Black Diamond then I loved my Icon for caving. It's powered by 4x AA batteries giving it a reasonable brightness and runtime, and it's next to bombproof. It's also supported by the excellent black diamond warranty.

That being said, I think it's worth going for a torch powered by Li-Ion batteries these days, as the newer technology provides better runtimes and brightnesses, although you have to look after the batteries a bit more carefully as they have impressive energy densities. There are lots of manufacturers producing little torches that run on 18650 Li-Ions (look for reputable brands like Fenix, LedLenser, Olight, Zebra, Nitecore) with good beam colours and shapes. Some have the lens pointing out from the side of the body of the torch such that it can easily be strapped on the front of a helmet (e.g. (https://www.torchdirect.co.uk/led-head-torches/nitecore-hc33-led-head-torch.html)), whilst others have the lens at the end of the torch so that they can be side-mounted on a helmet (e.g. (https://www.torchdirect.co.uk/led-hand-torches/olight-s2-baton-led-torch.html)). Loads of choice!

One thing to watch out for:- if you want to do any surveying try and avoid magnetic end pieces (which seem weirdly popular in these little torches from cheaper manufacturers) - they're a gimmick that you'll very rarely use and will muck up your compass readings!

I've seen a petzl ultra vario on inglesport. Has anyone got one?

I use an Ultra Vario. It's fairly bright with a nice wide flood, and weighs less than a Scurion.

At one point the light died, due to water getting inside. Petzl replaced it for free.

The Inglesport price is a good deal. They are selling it cheap because it's old stock and Petzl have replaced it with the new Duo S, which is brighter and more expensive.

Incidentally it is compatible with most of the accessories, so for example you can use those plastic bracket helmet mounts for Duos. Haven't actually used a new Duo battery with it, but fairly sure they would still work.

I use an old Duo with Custom Duo inserts.  Very good value, although people tell me it will start to fail for a multitude of reasons I've yet to experience.

It puts me off a bit that you can't use a battery pack that takes standard batteries, as the battery pack for the ultra vario is about £60 :(

Yeah, this is generally an issue with fancy modern lights, although some (like the Scurion, I think?) at least give you the option to use AAs and take a performance hit.

For someone on a budget:

https://www.fasttech.com/p/1319109

Perfect for strapping to the side of the helmet, extremely bright, cheap, takes 18650s. They have low, medium and high modes, plus some flashing modes but there is a mode where it will only cycle through the solid modes (this is the 3/5 mode thing).

I've got two, and they have survived a lot of caving and some canyoning (so they're somewhat waterproof).

They're quite focused so if you want a more flood-ish light you can combine with the light condom accessory: https://www.fasttech.com/p/1140010

If you want a Convoy torch for the side of your helmet then the Official Convoy shop on Aliexpress is the best place to buy. Buy one that has the new Biscotti firmware and you can select from a wide range of mode options.

You can also buy optics to replace the reflector to change the beam shape.

 I'm still hunting for a light at a reasonable price. How does Roy Fellows lamps measure up against the scurions? I've heard good things about them and the price is much more attractive.

I'm returning to caving after a break and am also looking for a light. I was looking at the Roy Fellows Lynx Basic. I think his lights measure up well against Scurions, they're just spartan on features ie less programs, and they look more 'homebrew' which is not a bad thing.

Holes need to be drilled to bolt it to a helmet though which is something I prefer to avoid where possible - my helmet has strap clips so I may end up getting one of the Petzl Ultra Varios from Inglesport.

It doesn't for most impacts, but having bolts on the inside may cause more damage in a head on collision, & you may not be able to do it with modern foam helmets.

Fair assessment.
But for anyone who wants to pay the money for shear quality nothing will compete with Mr Biffs new Rude Nora.

Onto my own
The basic is a bit basic as I am meeting a £95 cost target. Generally people have been happy with them, the only issues have been mud with Derbyshire diggers causing the buttons to stick.
I have built more expensive lamps with a IP 68 5 metre, 8 Newtons pressure push button, they they cost!

I like the idea of the light not being a hard bolted fixture - I've often thought that if the lamphead or battery box sustained a collision the strain on the bolts could possibly foul the helmet.

Definitely. I wouldn't hesitate to recommend your lamps - as you say there's a price premium with the Rude Nora and I think anyone looking at that or the Scurion have already decided that's what they want.

I have fitted and run internal cable on the new petzl Boreo helmet which has a large ploystyrene interior. Certainly this helmet you can completely dismantle for intalling and fixing the light

That was one of my concerns as I'm considering one of Roy's lights but my helmet has foam in it
Title: Re: Head torch opinions
Post by: royfellows on May 14, 2019, 08:48:48 pm
Nothing to stop anyone fitting bolts other way round, ie with the head on the inside.

My recommended fitting, cable wise is to run it round the rim and use a cable tie. You can actually mount a good backup (not an aspersion regarding my lamps!) such as a Fenix E11 on the cable. The cable is about 7mm of flexible natural rubber with 2 copper core, maybe a bit heavy for taking inside the helmet. Its also very important not to put any strain on it at the glands. The glands are top quality IP68 5 BAR with cable support, but if anything is put under a strain it will at some time fail.

I used araldite (other glues are available) to glue the bracket onto one of my helmets.
Was still going strong a few years later.
Title: Re: Head torch opinions
Post by: royfellows on May 14, 2019, 09:07:57 pm
I use either an Ecrin Roc, or for working, and I do a lot of this, a Petzl Elios fitted with a Dragon and a Fenix E11 attached to the cable to shine forward. Last weekend I was at it 2 days and didn't take a spare power bank, good as gold it went out coming out on the Sunday and I used the E11 to find my way out.

The thought occurred that the place for spare lighting is on the head not a hand held torch. I mean this big time.

Both the helmet types I use have a sort of loose foam band inside that makes it easy to work between this and the helmet shell. I cant really comment on other helmets, I would have to see one. However my intelligence tells me that if a helmet is so constructed that you cant fit one of my lamps, you wont be able to fit anyone else's either unless you plan on sticking your lamp on. I believe that there is a tape product that does this but cant recall the name of it. I have seen a battery pack stuck on with it and the user had to literally tear it off to remove it. I would be dubious though, and not really trust this. I would want to see a lamp bolted on for piece of mind.

Title: Re: Head torch opinions
Post by: Keris82 on May 14, 2019, 09:25:03 pm
Yes I would want to bolt on a lamp rather than glue it for security. I have a black diamond women's half dome helmet. Same as this one http://www.johncrossandsons.co.uk/black-diamond-half-dome-helmet-women-grey-2018-oeaorj-black-diamond-p-3176.html If you take a look at the pics I'm not sure how easy it is to remove the foam and drill it?
Title: Re: Head torch opinions
Post by: royfellows on May 14, 2019, 09:37:41 pm
I'm not sure either. The foam may pull away enough to allow drilling and bolting, but impossible to say without seeing it. My advice is to contact the helmet manufacturer before you buy any lamp, see my previous comments.

Looks a nice helmet though for the money.

Without seeing the helmet, it's hard to say, but if it was me, I'd consider drilling a slightly larger diameter hole through the foam from the inside, that the bolt head could be recessed into, then a small hole through the shell for the bolt thread.

Personally, I've never worried about drilling the odd hole in a helmet. It's mostly there to stop you bumping your head on the roof. If something falls on you hard enough to break the helmet, it'll probably break your neck too and if you fall on your head hard enough to break your helmet, you'll probably break too.

I like the idea of the light not being a hard bolted fixture - I've often thought that if the lamphead or battery box sustained a collision the strain on the bolts could possibly foul the helmet.
Seems a reasonable concern with these lightweight flexible shelled climbing helmets, however I would have thought that using a large washer would spread the load and mitigate the problem.

My advice is to contact the helmet manufacturer before you buy any lamp
I wouldn't bother. Almost certainly they will say don't drill it and use the provided fittings for an elastic band type head-torch, which is obvioualy non-ideal for caving. Also, the intended use is stated as "climbing" so perhaps they would just tell you not to use it for caving...
Title: Re: Head torch opinions
Post by: PaulW on May 14, 2019, 10:25:58 pm
i've drilled them like Pete suggest before

if you remove the 4 red clips shown on the ouside of the helmet then the crable will probably come out, and then the foam

I fixed my Fenix lamp (a HP 25R) to my helmet using cable ties around the head-band (and similarly for the battery pack at the back of the helmet), which means that there are no bolts projecting into the helmet:

To clarify, only Scorpion series is GoPro compatible. I would dearly love to extend this to the Dragon as this lamp neatly fills the gap left by the Stenlight at a reasonable price. However having these made would seriously jack up the price. It is possible to fit a Dragon lamp to a GoPro helmet bracket using some spacer washes, but its a hash up.

Go pro headband, I have just sourced a selection from £2 a piece. I will probably look for best quality for money and get some stock in. They are on eBay from £2.99
Having said all this, a rigid mount using bolts would be best option for any lamp.

Looking at the attached technical notice for Petzl's bolt on lamp mount for the foam lined Boreo helmet, it indicates that drilling through the foam is acceptable for bolt mounting.

The self adhesive Go-Pro mounts with the 3M adhesive pad stick very well. I've got one on my skiing helmet and one on my motorbike fairing. Both are solid.
Title: Re: Head torch opinions
Post by: Mike Hopley on May 16, 2019, 10:43:04 am
I'll just note that I tried using Petzl's adhesive mount to fix an Ultra Vario to a Sirocco (and I did sand down the surface a bit). This is not approved by the manufacturer.

It fell off after very little caving. I'm guessing it would have been okay on a hard-shell helmet (which is the intended use).

Then very shortly afterwards, they released a dedicated mount for a Sirocco. FML.

Post by: Commers on May 16, 2019, 12:14:08 pm
Will you go back to the Sirocco now Petzl make a light mount? I'm tall and prone to banging my head so doubt a soft shell helmet would last long for me...

Yep, I already have the new mount.

The Sirocco is not designed for caving so caveat emptor, but the new version has a hard section on top of the head. I've walloped my head several times and it's not showing any real sign of wear yet. And neither is the helmet.

Mr Seddon described it as "intelligent misuse of equipment", which I think sums it up nicely. Time will tell.

How do you detach the Vario's battery plug from the rear plate of the headstrap? (see attached image). It looks like tugging it sharply to the left would disengage it but I'm worried I break it.

You need to push it to the right (as seen in that image, you can see there is a gap on the right of the plate). Don't tug on the power cable.

It's a little awkward. I get really close to it -- maybe bracing my hands on my legs so they don't move too much.

I was thinking about buying something like that  - I was looking at Zebralights - for a backup light. But for a main caving light I'd always choose something from Roy Fellows, Scurion, Rude or Petzl for a more convincing assurance of aftersales service.

I have used Zebralights exclusively for the last five years or so. I generally use a white beam with a hot spot for general caving and especially big passages and a super wide, warm beam for sketching and small passages. Can't remember what models. Single 18650s. I don't want anything more out of a light, they have functioned perfectly through regular heavy use, are bright and tough and small with excellent runtime.

I had to return my fenix HL55 recently because the contacts got loose and the torch stopped working - bad design flaw!  :(

What exactly do you mean by this? Did you consider just bending hte contacts back into place? Or that maybe you didn't screw the cap down hard enough... Maybe I have misinterpreted the problem. Either way that NiteCore HC33 that Ari posted looks pretty good.

I did try bending the contacts back in place and stuffed foil in the spring. It worked temporarily but still lost contact so I got annoyed with it and returned it. I always had to screw the cap on very tight but there's only so much you can screw something!

That looks so good that I've gone and ordered one. The things that really appeal to me are the very light weight, cheap standard batteries, and of course having a spot and flood beam (which I haven't seen in this type of light before).

Why are people fixated on needing a high amount of lumens? Obviously the amount of lumens you need depends on the passage you're negotiating, but in reality you really don't need more than say 400 lumens the majority of the time.
My main setting for general caving is 150-160 lumens in a wide angle beam. Occasionally I'll switch to 300+ lumens of narrower beam. If I know I'm going somewhere that is big I'll take my 5000 lumen hand held.

I am underground on my own most of the time, and in mines at that. I started exploring slate mines on my own, hence the quest for more light. Powerful torches never appealed to me because I wanted it on my head leaving both hands free. In the company of others I find it quite different as I have the benefit of other peoples light. However, large chambers still appeal even if I am with others.

For the past few years though, I seem to have spent most of my time working underground. In this case light weight is what I want. Max output is collateral, and seldom used.

Not always a good idea; I remember going back to Oxlow Caverns after an absence of many tears, and being appalled by the state of the ceiling in (I think) West Chamber; with our good modern lights we could see how unstable it was, whereas with the crappy old lamps we used to use we were unaware of the hanging death . . . 'ignorance is bliss', eh?

(By the way, I have a Fenix HP 55 that has never given me the sort of trouble described above.)

Over Easter, I forgot my helmet on the way to Juniper Gulf and hired one from Inglesport. It came with a Petzl Pixa 2. I was amazed how comfortable it was to have so little weight on my head. It's only 80 lumens on the high setting, and most of the time I used the low setting of 20 lumens to save batteries. 20 lumens was dimmer than I'd prefer, but still perfectly usable.

For the last 10--15 years, "the best" caving lamps have been widely considered to be the brightest and most expensive. These lights have basically copied Scurions. They have a visibly (perhaps ostentatiously!) robust design, with metal bodies and battery boxes. They mostly use expensive custom batteries.

I think we're starting to see a change in that. For example, American cavers seem to be using Zebralights a lot, which are light, cheap, and use standard batteries. The Carbi light looks interesting. I like the idea of a flood beam that fills all your peripheral vision.

I suspect most cavers (including me) will still want a reasonably bright light, but we'll start to see more interest in other factors. How much does it weigh on the head? Does it have a warm/neutral light? How wide is the flood? How much would it cost to buy enough batteries for an entire expedition, and not even worry about recharging?

I don't understand why cavers think anything made of plastic is flimsy. The Pixa headlamps, for example, have been specifically designed for robustness in professional use. See Petzl's video, where they "crush" the light with an 80 kg weight (jump to 40 seconds in):

The reason for a high lumen lamp is because I like to do photography and also do a caving trip once a year to a different country and without a powerful light in places like the vercors you cant see much because the chambers are so vast.

Not the issue, Steyr AUG assault rifle made of high impact plastic, as are a lot of modern car components, camera and other stuff. Issue for lamps is Heat Conductivity = Zero

Aluminium lamps can be light in weight. Stenlight 125 grams, Rude Nora (latest) A remarkable 110 grams, dont know he has done it!, and my Dragon is 130 grams

Presumably those weights do not include batteries, or even the battery box? Still good regardless. :thumbsup:

Not saying "metal is a bad material for lamp casings" at all, but I'm guessing we'll see lighter designs being used more over the next decade, with a compromise on how much sustained light they can put out.

My excuse for wanting high luminosity is due to my poor eyesight in the dark lol! I don't like wearing glasses or contact lenses when I cave so need all the light I can get!  :blink:

That's VERY cheap. I would question the quality. But for that price I suppose it doesn't really matter. I would want to test it on some small trips first

It does matter if - for whatever reason - you find yourself relying on the thing to get you out of somewhere.

 Hi Keris
I don't know why you are bothering with all the cheap/middle range options.
You have decided to go caving so invest in something like a scurion.
You are only young so if you cave for the next 15 years it works out good value for money.
Just saying 😉😉

Actually I have decided to invest in a scurion now. I shall be getting one from Tony next week :)

Why do people always associate inexpensive with poor quality and unreliability?

There's numerous posts on here about people having problems with expensive caving lamps.

Whatever you decide to use as a main light, always make sure you have a back up.

I have a Fenix headtorch here from Mike Moore, unsure what model,  if he is around he may care to comment.
It packed up and on examination water ingress to the battery box was the issue

Frankly, the 4 series AA battery box was unfit for purpose. mike is no sump diver and yet water managed to get in. The end rubber seal was easily peeled away even when secured with the screw. The intention now is to mate it with a 4 AA Petzl Duo battery box.

If anyone has done this and there is something I should know about please tell.

A Li Ion pack would be better but voltages don't match.  4 series AAs will give 6V off charge, depleting. Li Ions are single 4.2V depleting, or 2 series 8.4V depleting. I could probably do something with a DC DC converter but its not worth him spending the money.

An idea that has just occurred is to put a USB plug on the end. It would run off any 5V power bank then.
Ideas in action.

If it's this one:

then its only rated as IPX6.

I've got a Fenix HP12 and would definately trust it as a main caving lamp. The weak point would be the cable from the rear mounted battery housing to the lamp unit. You could protect it with a bitof split tubing though.

I don't use it undergound though, I'd cry when I bashed it on something and scratched the nice anodizing.

I'm quite happy to bash my bastardised Oldham on anything.

I have a fenix and have had for 3 years. Brilliant light cant fault it but I decided to upgrade and was suggested elspeleo terra. big mistake had problems from day one and had a replacement lamp and still problems. Cant fault there customer service as have been offered a refund. So I'm looking for a reliable upgrade around the the same money that can produce anything from 1100-1300 lumens. Any suggestions
I’ve got the Terra and kind of wish I went with something else. When I ordered and paid for it it was sold as coming with a 7000mah battery and charger but I was told some improvements would be made and mine would be one of the first. I waited 3 months for it to turn up and the “improvements” appear  to be that it now comes with a box that will only hold a single battery (not supplied) and no charger. Using it with a decent battery I struggle to do a 4 hour trip without changing the battery which I don’t like doing underground. I tried emailing to see about buying the battery pack that it should have come with and I haven’t even received an answer so I won’t hold my breath that it would be replaced if there was a problem. It’s a shame as I’d heard really good things about Elspeleo but with hindsight  I should have paid the extra and gone for a rude Nora 3.

I sell lamps so I take mine out of the equation.

Latest Rude Nora is shear quality and basically buries the Scurion by offering better spec than dive model at around the price of the Scurion basic, Oh and by way, only weighs 110 grams. Whatever you buy you need to go unto things and not get sold on trends, looks, or must be good because so and so uses one. So and so may be getting paid to use whatever.

My Terra flooded after a single trip through Swildon's sump 1, but Elspeleo replaced it for free and I love it. Saw me through a 2 night camping trip in Daren with no battery change and good output throughout!

Having said that, I would not now buy a lamp with a cable as I think they're an unnecessary vulnerability.

I spoke with them on Facebook and they were very prompt to reply.
