I have never actually seen one but they do look good to me. Problem is as far as I can see that they have moved to the USA and if you have to pay their postal charges you will probably end up paying nearly double the price.

Tell me if I am wrong.

I think you're wrong

So how would I buy one from the manufacturer in Croatia?

Do I need to go to Specsavers?

So in the form I have to fill in I enter under "Content" (the main message field) "Please, I would like to buy a lamp"?

It probably is my fault as I expect to see "Add to basket" or similar, I can also perceive a difficulty in not knowing the  price I have to pay which could be a problem with PayPal who usually require a figure.

As said before, the lights are made in Rijeka, Croatia. So no customs charges. He usually makes the light only after you order it so you can choose the tint of the emitters and so on. If he has a few in stock he usually posts it on his facebook page as they sell quick. When I was ordering mine, I called him on the phone (I'm in Croatia too) and to check if he had any available and discuss what I would like to get, but all the subsequent communication was done via email.

Oh, yeah, I think I read on FB that you can use the new 10500mAh battery packs on the regular Rescue model too. You just have to buy the battery box for the bigger battery pack.

I get a lot of kind praise for my lamps but have to add that the gentleman needs a dive lamp which do not make.

Mine are IP67 which is a miserable 1 metre, and thats water as well, you know, the stuff that comes out of a tap. The switches dont take kindly to sulphuric acid, it corrodes the lamp as well.
(Insider joke)

EDIT
The insider joke is some mine explorers, I worry for them never mind the lamp

Hm; Roy - have you never considered running up a lamp that'd be OK for cave diving?

To pay £700+ for a Scurion is just silly money. Particularly as it's designed to be mounted centrally (lots of scatter in less than 100% clear water). I still prefer a group of torches mounted on either side of the helmet - you don't have all your eggs in one basket, the scatter problem is less - and if one fails (which is vary rare with good maintenance) then replacing just one in the bunch is cheap.

If you could come up with a rechargeable torch design which is small, bright - and not too highly priced, I'd certainly be interested in buying them in multiples of 2.

There are a lot of issues involved, primarily that I only make lamps as a hobby, and am 72 and like a laid back lifestyle.

I struggle to keep up with demand for the lamps as it is.

Looking at diving lamps. I have talked to divers and been acquainted with pressures as depth. Ouch

For a start a lamp would have to have a permanent fixed battery pack, hopefully one that an owner can replace cells easily. Ones produced appear to fit this criteria. The issue with detachable battery packs is that water would be forced up inside the cable. I wonder how many people realize this.

Moving on, second issue is the switch. Easy option here is of course magnetic, and if soft switching is used the current rating would be very low.

The seal on the battery pack would not be too much of a problem, but the pack would have to be CNC machined out of solid material. Cost.

Lamp itself, what remains is the cable gland and front lens.

Most lamps use polycarbonate which is machinable, but unfortunately will scuff and scratch over time which will affect the beam pattern, hence my preference for glass.

The bottom line on it all is that I could probably produce such a lamp but it would not end up much cheaper than dive Scurions.

A couple of weeks ago I had chance to see both a El Speleo and Phaethon, the former being described as waterproof to 40 metres, the later as suitable for up to a depth of 250 metres and tested to 7 bar. Both looked good to me.

I think that you have what you want there, unfortunately no UK agents which would be desirable.

John, I've got 2 of these - they're pretty good and the price isn't too bad. Recommended :)

Thanks for the information - next time I bump into you in the Dales I'll pick your brains further!

Torches are a different ball park as batteries are internal. The Chinese are offering quite a few which are dive rated.
I have have done a few conversions to Kowalski dive lamps some of which were bought by the customer cheaply off eBay as not working.

I solder up a copper insert with good contact to the aluminium case for heat transfer, an array of about 6 18650 Li Ion cells, and 4 Cree XM-L LEDs to give a maximum output of about 4,000 lumens. This buried the original bulb.

Looking at Kowalski lamps now, the basic design appears unchanged.

I was charging about £100 for the conversion. But before anyone gets a hard on, there are some components that I cannot obtain anymore. When they become available again, if, I will offer the conversion on the website.

Hi All - so far my Phaethon has been fine, but wouldn't feel happy about recommending it until 100+ dives. The xtar D26 give an amazing amount of light for the money £about50-60 from memory - the only minor gripe is that if that are not locked off they come on after a few metres of depth. But you can easily switch off and lock with 5mm cold gloved hands ok.

I see that Javier (maker of Barbolight) is making torches again. These were the best I've ever had - not caving/helmet lights but 400+ dives and they are still great. No idea on price yet but they were very good.

Underwater Kinetics SL4s have been good too...
