Was perusing Amazon and came across a listing that I first thought was for an FW3A ... It was posted on Amazon in mid-October, with no reviews for it. I start looking through the images and one of them shows an output chart listing a Turbo output of 880LM. Then I looked at the description and it mentions the "FW3EL". I assume this is going to be an "Extended Life" version engineered for a much longer runtime?
I googled FW3EL and came across a mention of it on the product description for a Lumintop diffuser ...
This appears to be a version of the FW3E with a basic UI (and seemingly reduced brightness, but I’m not sure they meant to write High and Turbo as the same since they still tout 2800 lumens as the max, and the runtimes are different).
The FW3E differs from other models in that it uses a battery with the positive and negative terminal on the same end, in order to avoid needing an inner signal tube (and improving reliability). This does make it harder to source cells for this light though (much like Olight’s proprietary cells).
