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.

Very creepy start to the video. A grown man acting out a sex scene with flood lamps ??? Weirdo.
+bigclivedotcom – Question; If you were going to double the battery capacity in this unit, could you just parallel them in pairs and use the existing protection board for both sets of batteries; Or is that a bad idea? (Learning more on Li-Ion batteries still) – Also, I'd think if you were just to solder a charged cell in parallel with a discharged cell that would result in some serious heating from excessive current, what is "the" best route to equalize charge in these, strap them together with a 10 ohm or something power resistor, let it equalize over night, then connect them directly?
Can u put the $500.00 LED in it? The LED that emulates the sun? If anyone need one, you do Clive!
Would it be possible to replace this LED with a Cree full spectrum COB for usage in the greenhouse?
i tired breading them and a Nitecore came out
What is the best lumen light
The cob chip or three watt chips?
You know it's a good light when you get all 4 screws!
I want to see Clive's workbench in full.
as i said earlier i hade one of those from jaycar each cell was rated at 1500 mah each with 4 cells
i had one of those from jaycar with 4 18650 cells
