Used one for years, fantastic project caving light, you can even cook vienna sausages with the flames. The heat came in handy once when I was in a small passage that had some rockfall at the entrance, I was stuck for a while, and the light provided some warmth.
Having said that, the lamp is no longer on my helmet, and I don't carry it into caves. The petzl generators are good, but all generators can be a little finicky, requiring you to play with them through out the cave, LED lights don't.
It is good for demonstrations in science class though! Kids LOVE that you add water to rocks and get FIRE!!!!!
