Lights

For a cheapo light this is sweet, has one of the cree LEDs in and has done me well for nearly a year.

Bargain. What batteries do you use, and how long do they last ?

If it's really 3W, you'd need to find roughly 4 x 2500mAh AAA batteries to run if from to get 4.5 hours out of it. The best lithiums I can find off hand are about half that, and good NiMH AAA rechargeables are usually about 800 to 1000 mAh.
