I was surfing the net this morning for something else and stumbled on this guy - TruLight Caver
It's made in New Zealand, and is in the same price range as a Stenlight. It features a spot and 2 floods, and each seem to be independently controlled. The battery is a lithium ion pack. A neat feature is that one of the floods is specifically designed to be an electrically redundant backup light. It has a small independent battery contained within the main battery package, and separate wiring and switch.
All LEDs are 1W Luxeons, and therefore the brightness and runtimes are not quite as impressive as competing lights. I don't know why they're not using 'industry standard' 3W Luxeons or SSCs, but perhaps their original design pre-dated these more efficient LEDs?
Anyone own/used/seen one of these? Other than the manufacturer page, I couldn't find anything on the web. No reviews, caver comments or anything. Maybe they're too pricey for cheap Kiwi cavers, and nobody else knows about them?
