I was given this EVE floodlight as non-functional. Although it came with two panels neither was the correct one (not even the same connector). It has no rating markings whatever!

 

So, I charged the beast with a power supply. About 7.4V and 2.5A seems to be the sweet spot, charged until the BMS cut off. Light ran for nearly 24 hours (getting pretty dim by the end).

 

So, since it's "a good un" it needs a panel.

 

I suspect a 12V 30W one would do the trick, but ideally one matching the original.

 

Anyone got a light like this and can post the panel details please? Even if the panel is unmarked, we can guesstimate the power rating from its dimensions.

To keep charging circuit simple and maximise efficiency, most of these solar lights use 6V panels (around 7V open circuit) to charge their Lifepo4 cells. The measurement indicates it is likely a 100W model where the panel size would be 6v 20W or even greater for a better quality light.

I just charged the beast from flat with my power supply @7.2V, it swallowed 135Wh before the BMS cut off.

 

That's suggesting that a 30W 6V panel is going to be the right beastie.
