Thank you TheFraz for taking the time to answer all these questions.
So good to hear about a 26650 Lumenite in the (hopefully) near future. As mentioned before, I will send you funds when you are ready. Still hoping for an anodized not dyed black body (silver is nice) that can take a protected 26650 (I can send you an Orbtronic.com battery if that would help). Yes a protected battery adds complexity but the battery can be replaced if it fails. There is concern with an emitter getting too hot for too long and lowering its life cycle but a protected battery wouldn't help with that, only a prudent user could. Ideally protected and bare cell could be used if possible?
The other request is that you can use an LED that has very good color rendering without distracting colors in the corona, etc. The Samsung 4000-5000K LH351D is my current choice but if it needs to be that Nichia E21a, hopefully that will be ok. Our application will be as an area table light (ceiling bounced) in our off grid house, used every night.
How do you like to be paid? I would also like to purchase a spare QTC if you are willing.
