In the movie The Cave, they were using their cave diving lights when they were out of the water. There is a battery canister that is hip mounted, a cord and then a strap to fit around the hand, so the light is on top of the hand. They come in 10 watt to maybe 21 watt HID now. Companies such as dive-rite, halcyon, and Salvo make the lights, however I would not recommend them for 'dry' caving use. The bulbs can get very hot, they are designed to be used under water. Also the test tube that covers the bulbs is fragile, and very expensive to replace. The lights cost from $400 as a minimum price, but most are more expensive than that. Remember that The Cave was a Hollywood creation, not everythign they did is practical in the real world, it was done for entertainment purposes.
