Corey and Joel at Light Monkey have been our longest supporters, fixing my continuously worn out equipment without a word of complaint, even when I show up Friday morning and need it by lunch. Their customer service is the best in the business bar none and their lights and gear take a beating. I've never had a Light Monkey light quit on me in the water or in dry cave and I treat them BADLY. (I've never even broken an HID bulb in the 10 years I have used the same light!) We are currently diving Light Monkey 32W Focusable LED lights with 10Ah cannisters and backup lights, as well as Light Monkey reels, drysuit pockets, the new heated undergarment (!), 10Ah heater packs with integrated controllers, line arrows and storage buckets! You can check out all of their products on their website: http://www.lightmonkey.us/
The 32 Watt adjustable head has a tight beam for easily signalling your dive buddies, and is much brighter than my Light Monkey 21 Watt HID. Since you can change the brightness with the switch, two steps down is equivalent to the 21 Watt HID, but only draws 7 watts, giving the 10 amp hour canister an almost 20 hour burn time!
I will be testing out this slick undergarment in the 37 degree (F) Canadian water this summer. It wears like a midweight capilene undergarment with integrated front and back heat panels!
An empty reel is the hallmark of successful exploration, and nothing makes that easier than light monkey reels. They don't jam, the line doesn't fall off between the frame and the spool, and you can actually feed the line through the gap in the water if you wrap the line up too far.
