I like it
Basics
Body: aluminum
Power source: 3x AAA in a carrier.
Emitter: Genuine Lumileds Luxeon® Star
Switch: Reverse clickie, probably not water proof
Price: kind of expensive. $20 ish
Physical
Weight: 5 oz with batteries
Size: 1" diameter and about 3/8" shorter than a 12 oz soda can all put together.
Electrical
Drive: 2.0 ohm series resistor
current, fresh alkaline: 0.475A
current, stabilized* NiMH: 0.225A
*stabilized defined: NiMH starts off around 1.35v and rapidly drops to 1.2 to 1.25v and maintains this voltage for most of the discharge. The technical term for the stabilized voltage is called the midpoint voltage, but I'll call it stabilized.
Based on these measurements, you can roughly extrapolate that with NiMH batteries, it will maintain 1/2 the output relative to the output with fresh alkaline batteries.

The battery arrangement allows for shorter length while being about the same diameter as the Sears light. In my opinion, this light has an excellent thermal solution. It actually uses the Luxeon star, which is mounted onto a piece of aluminum with thermal compound and the piece screws into the body securely creating a good thermal path. Just for comparison, the Sears Tool Light has a horrible thermal solution. Luxeon emitter mounted on a PR base and installed into a plastic socket will make the assembly too hot to touch.
High temperature is bad, because the efficiency, output and life of the LED are all reduced.
Now for photos....
