    An informative discussion

    Recently there was long thread about the BCA. I can now post possible answers to some of the questions, such as "Why is the BCA still raising membership prices when there is a significant amount still left in its coffers?"

I would say neither, just personal choice.
Actually neither as no big beam.
I use one of those origonal nova fives with Lithium battery but no beam,
which is great for mendip but crap for big Yorkshire or continental pitches, ie spit spotting :-\

I use carbide only very occasionally these days. LEDs are so cheap and convenient. The killer blow for most trips is the weight/hour of light argument.

However, this summer I took my carbide on a couple of trips when I was P-bolting a cave up north of the artic circle. I needed a powerful light to plan the work and I knew there was going to be a lot of hanging about in an extremely cold cave. I can tell you, everybody on the trip was extremely glad of my carbide light. We were huddled around it waiting to go back up the pitch.....

So, it still has its uses, but I don't take it out very often. It is kind of fun as well. It's like driving a vintage car. You wouldn't want to commute to work in it every day through the winter, but on a nice day it can be a refreshing experience.

So, there you have it. If you are caving in the artic circle carbide is a good plan. I presume it's fair to say, conversely, that if you're caving in the UK use LEDs instead or am I poking a sticky-thing into the nest of furious antique lovers once more?....

Consider that stick well and truly poked again...

It can be f*cking cold in UK caves as well. I went to the end of White Scar one winter, the day after the snow melted. :(  I would have killed for a warm carbide generator that day. It was positively arctic :eek:

It was so cold, on the way out we passed a small gold coloured monkey who enquired of us if anybody knew how to braze ;) ;)

but, as well as knowing how to braze, you'd have needed some acetylene for the brazing torch.... :LOL:

Hmmm A cold cave can be combated by weraing a T-Shirt and Ron Hills (or tights  :unsure:) under your undersuit. It warms the whole body.

Relying on your light source for warmth indicates poor planning....  :)

Like I said, if only I'd had a carbide lamp... o_O

I had full thermal underwear, a cut-off furry suit and a second complete furry suit on top. Plus a thermal hat. With more clothes on it would have been difficult to move.

That's why I took my carbide light and had the generator inside my suit while I was waiting. It was good planning. Just like putting on the central heating in the winter is good planning.

I took the carbide mainly for warmth. So you could say I was relying on my heat source for light, rather than the other way around.

But then, you are skinnier than most of us.

The new trycaving.co.uk website is suggesting CARBIDE as a possible lighting source, and not an obsolete lighting source.

Apparently, "Although a bit maintainance heavy when working smoothly the carbide light gives and excellent ambient all round light. Downsides are the added item on the belt, possible polution. With the new LED systems out there we use carbide less and less these days"

Apart from lack of appropriate punctuation, and spelling mistake, anyone want to comment on this?

Yes, I know, we've been over this many times. :(

I assume it's a beta version of the website?

For beginners, downsides of carbide also include a possibly greater risk of
a) burning hands+gloves, especially on vertical work.
b) melting traverse lines.
c) having a light that might just go out for no obvious reason while they're in the middle of some manouvre *before* they have developed a caver's skills for memorising their immediate surroundings.
d) carbonising the cave roof, etc.

Basically, all down to someone understandbly having their mind on other things while learning how to cave. If they're gong to end up running an electric most/all of the time anyway, they may as well not bother with the carbide at all.

I'm not sure I'd lend a carbide setup (even a good one) to a beginner. I'm not sure I'd advise *anyone* to buy one - even if someone was likely to get good use out of one, there must be shedloads currently rusting away in, erm, sheds.

The equipment bit has been borrowed from the Willerup brothers' website; they wrote it and I imagine it's not possible for the trycaving webmaster to edit the text. It would be nice for the info to be altered but there's loads of stuff on t'internet which ain't exactly gospel/accurate so there's not that much of a surprise.

While browsing another site in reference to my post about a new LED lamp, I came across this article. Makes very interesting reading with reference to this discussion

The article is a bit out of date regarding LEDs - current efficiencies can be something like twice the 25lm/W figure quoted when running at ~1W .

The assumption that for a long expedition, you need an LED lamp running at a *minimum* brightness defined by some similarity to carbide seems an assumption too far.
There's often a lot of time when you aren't moving fast, or when for other reasons don't need maximum light. Whilst it might be *nice* having full-power light all the time, faced with the choice of carrying loads of extra batteries or using light more frugally, many people do go for the latter option.

Well I use my carbide light at least 4 times a year,

3 times during fresher's week because if you are trying to get people's attention, fire is a winner!

The other time is on the fresher's trip, when i know i'm going to be sat around for ages... having a light that also provides at least 5 hours of heat can't be frowned at!

However, I do use carbide in biscuit tins... plastic bottles... bins etc... quite often!  (y)

The main use of carbide then seemed to be dropping bits in the inkwells before leaving the classroom at the end of a lesson - the resulting stink made the room practically uninhabitable for the poor so-and-so's who were there for the next class...   :LOL:

You can't do that with a rechargeable Li-ion cell...

No, but Li-ion cells do make an impressive explosion when placed on a fire... Just like a carbide bomb... but a bit more 'dangerous'... :blink:

Has anyone tried the new "some metal"/polymer batteries that are kicking about I've seen lots of pritty facts and figures but no batteries. Supposedly you can get 3500+mah off a single aa... and they recharge.
