There is a River Rock series that is identical to this Nuwai for $9.99 at Target.

It claims to be a 0.5 watt light, but under real world conditions, it draws around 0.2 watts from the batteries. By under real world conditions, I'm excluding the initial boom of full output that lasts five minutes.
Current draw at 2.5v input (1.25v per cell) was only 80mA, which is 0.2W. Give the step up converter 85% efficiency and you're only getting 0.17W to the LED.
