1,750 Lumens and for the really big chambers in Slate Mines, it's still not enough.

I'm planning 6,000 Lumens. (Yes, Six Thousand). It's a matter of Money to build it though, the Driver alone Is 50, LED's will be 60. Then I need figure out a way to heatsink LED's that are burning through 18A at full power. Oh, and mount this on a Helmet. I have one LED on order to test, and if it works out as I expect it to, the rest will be ordered to make it.

crickey 6000 lumen's you could almost grow stuff under that. That lupin is very expensive. I was looking at at some of the chinese ones on ebay theres a couple at 1600 lumens but a lot of people say they are not that good.


smoke me a kipper ill be back for breakfast

You can get the Betty cheaper than that, but it was the first link to hand It's still not cheap, but it is bloody good though, and has never let EWJ down. The build quality is excellent, and he has the 1,750 Lumen upgrade... it's 1,500 as standard.

Mine will likely be handheld, for short bursts for photography and checking stuff out. Inless I pull something really special out of the bag of Technical Tricks, I doubt I can heatsink it for constant running at full power.

well you're on the wirral, so north wales, there is literally hundreds of old mines in various states of dis-repair. as a general rule of thumb, the easyer it is to get to and access, the less there will be to see in there.

your best bet is to go wiht a few people who have done mines before, some can be quite dangerous
