Convoy L6 UV Rock hunter build 10W+ LED -need build advice

Tons of info on this forum, thanks to all who post it.

I’m hoping to build a10w+ flood for rock hunting based on a L6 host
hoping for 2hr run on high.

please suggest the best 365nm 10W+ bulb, energy efficient driver 10W+ capable, long life batteries and reflector choice for this L6 build. I will be using a ZWB2 lens filter.

thank you for any help/advice you can offer.
