The most 'useable' (convenient, reliable, ergonomic, roll flexible) lights that I currently grab for spotting wildlife and video work at night time are the SR90 & SR95. I can spot deer sized critters out to about 300 meters and can project enough light for video out to about 175 meters. The SR95 is the brighter, lighter, longer running replacement of the SR90. There's also a SR95UT throw version which utilizes the SBT-90 LED but having borrowed one, I find the extra lumen output and beam angle of the SR95 to be more useful for the task.
The SR51 that djans1397 mentioned would be a smaller, less expensive option and still give reasonable performance but it has about 70% less throw than the SR95.
None of the Triple XM-L's will be in the same league with regards to Peak Throw Lux as the single, large emitter lights. For example the TN30, TM15, EYE-30 & EYE-40 Will have about 1/4 the Peak Throw Lux as the SR95.
HID lights are awesome performers but when you throw in travel convenience, role flexibility & run-time into the mix, sometimes, all but the most expensive HID's can be cantankerous compared to LED.
A SR95 is under 3lbs and can be put in a backpack or slung over the neck like an SLR camera. After a while you sort of forget that you're carrying it and it's great for getting in and out of vehicles because it fits tight to your body.
I hope that helps...
