I do not think I would ever buy an HID light ever again. LED all the way. There are excellent LED lights on the market these days some with triple or quadruple 5 watt LED. I use a 3 watt LED as a day torch and back up and a 5 watt LED for night diving. However I dive in the tropics where I do not think you need a massive 'floodlight' type light. I find these lights intrusive, they startle and wake up sleeping marine life. Have a look at the Aquatec LED torches, all less then US$100. IST also do a decent rechargable light with triple 5watt LEDs for about US$200. LEDs have a much longer burn time and are in the long run way cheaper than any other type of light on the market.
