Inside another ebay rechargeable LED work light.

One is never enough. When I get interested in something I want to buy a few from different sources and compare them.

This version (also from ebay) is pretty similar to the other, except for the plain use of a 2.4 ohm series resistor in the LED side of the housing. I suspected there was just a 1 ohm resistor in the green cased version of this light and the difference in resistor value may explain why the green cased unit lasted just over 3 hours on a charge while the yellow one lasted a good 4 hours. (Both gradually reducing in intensity over the discharge cycle.)

The internals are pretty much identical with a protected and balanced 8.4V (2-cell) 18650 lithium pack tucked in the back, with plenty of room to double the capacity if you are so inclined.

This unit also uses the odd 8-chip LED with four series circuits of two all connected in parallel to suit the battery voltage. This does limit the replacability of the LED. This version has a typivcal cool-white light output.
