I have looked a Dave's videos about his light and upgrades, I have also tired to read on this forum and other places but I can't seems to find some, for me, easy to understand, guides and some "bye that product". I am using 240V. As I do understand, can the light make color look wrong and that would be a bad idea for me, since I also have to use that light when I mix tiny amount of paint. My ceiling is made of one single layer plasterboard screwed to some thin wooden beams, so not too heave <10 lbs per lamp. It would also be nice if it is long lasting and easy to change the "light bulbs" that do not flicker on video. Oh and I would really like to avoid any of that annoying hum some lights do make. :-) |

I used over a long time fluorescent bulbs; then I got a LED bulb with the same lamp socket, but it produced a lot RFI; some month ago I bought a RND magnifying glass LED lamp. I had to get used to the cold-white LED colour since I was used to warm-white, but it's really pleasant to work with it. brightness is adjustable and the lamp is RFI-free - what is the most important to me. |

If you have the money build a 100W Yuji led room light using a 50W 3600k and 50W 5600k COB emitter + heatsink + fan. Using two emitters you can then tune the color temp to your liking between 3600 and 5600k I used two 5600k emitters on mine but i think it would be better a bit warmer, maybe 4000k. |

My general room lighting is two 4200 Kelvin LED fixture, I think 1700 lumen or something each. Then right over the work desk, there is a 5000 K stick type LED fixture (one looks like regular old florescent lighting) hung low to the table. This one can be turned off easily from sitting position. Very good for assembly and visual testing work. I like BRIGHT. What didn't work for me were any type that sits on desk. They kept getting in a way. Unless you go extreme, your eyes adjust to lights' color temperature. I never had issue with color recognition with this setup. |

(CRI > 90%) https://www.beleuchtungdirekt.de/osram-l-36w-965-lumilux-de-luxe-120cm-tageslichtweiss Led lamps often have only about CRI ~80%. With best regards Andreas |
