Hello and welcome to BLF :smiley:

The light you have is a higher quality variant of the AA zomie clone which is available in all sorts of brands and prices. AFAIK it performs pretty decently and the 300lumens claim isn’t way off.

In order mod it you would probably have to invest in new led emitter and driver, and make sure there is sufficient heat sinking in the head to cool it down, It’s not impossible but in my opinion not worth the effort or cost, mostly because of the zomie head itself.

A common reflector is the way to go and if you check around the forum you’ll find great performing and inexpensive lights that can deliver the 500lm you’re looking for and even more. If you’re interested in a new light just let us know your budget.
