Light colours

[Hatstand]

I mostly visit Mendips ATM but I also see a fair few mines (with quite large chambers) - I was really wondering if there was much difference between light-types when used in a slate mine, for example, where the rock colours are quite dark - basically which type of light would allow me to see better (if there is much of a difference) or even if a coloured filter might help.

Having done lots of Slate Mine, I concur with an earlier suggestion that the colour temperature issue is a red herring.

My observations:

Nova 3 = Fan-bleedin-tastic in natural cave* for all previous stated reasons including lack of battery pack and longevity. Not so good in slate mines. Not sure why, don't really care, just know.

Prefered set up for slate, oldham and 4 cell Mag. Don't think prefer oldham for colour temp and certainly not for brightness, but think for throw and spot of beam.

Have used large rechargable spot from car type shops. Bloody excellent in massive chambers, pain in arse to carry round though. Depends on purpose of trip as to whether I would bother.

Out of date marine flares - fantastic, but beware of smoke

Lights?

I do braille caving. Doesn't everyone?

Is that what they mean by following the dots?

Probably the best type of light for a mine is a tallow candle stuck onto a felt helmet with a blob of clay.  If it was good enough for t'owd man it's good enough for me.

Judging by the muddy finger marks on what were once clean walls and calcite formations, yes.

Aha! You discovered the irony.

Do you visit town in your horse and cart?

Or pony and trap?

Yes! All over the  calcite!

Damn right - what we need is a more exclusive and elitist approach to put off novices that lean on all the wrong bits - that should sort out the caver numbers good and proper and make sure all the caves are preserved in the best condition - hell lets ban digging and cap all the existing ones while we're at it and just go to the pub!

Our local sports centre has signwritten AND braille signs on the automatic door.  I did bring it to the notice of the staff but they said "no-one else had complained".

:doubt:

Hatstand - i think you raise an important point.  My viewpoint is somewhat biased by the fact that (at the moment) I have no mine experience/aspirations at the moment, and I like caves for their "sporting" aspects.  The views to be had are a very welcome bonus indeed, and arent often beyond the reach of my light.

For a slate mine there's a lot to be said for taking one of the big rechargeable spotlight thingies you often see on sale in car accessory shops. They'll only last twenty minutes or so but that's fine cos you only have it on for a minute or so at a time.

Also useful for looking down Titan...
