Ceiling bounced ~2200K, remotely controlled lamp

I wanted a late night time source of cosy, warm and high CRI light, which I could control remotely (On/Off + brightness).

Lumintop Apollo modded with 4x 519a 2700K dedomed

- no battery inside
Noctua 5V fan (very quiet)
radio controlled USB “extension cord” and the pilot with On/Off and power level regulation

It looks ugly but works beautifully. Fan allows to run it on ~Turbo level non-stop and remain lukewarm.

Mission accomplished

Does dedoming change the CRI/CT/etc. by much?

I wasn’t sure if 2700K→2200K was a typo or just what happens after dedoming. I can’t keep track of the ways all different emitters “warm up” and by how much after shaving/dedoming/etc.

Man, I miss those threads…

Perfect.

The only light I have with a 519a is the Pokomon 2AA, at least I think so.

Just unearthed it, man, that’s a nice beam…
