Does this qualify for lower price and free shipping or is the price bracket applied individually? Thanks! Just in time for some home lighting projects:)
Great comparison, all the 219C look amazing.
Man that 3000K is totally incandescent!
I’m very impressed with the warm neutral of the 4000K
Clemence, thank you for the beamshots!
4 x single 219C 90CRI 4000K on 16mm copper MCPCB

- 144A doesn’t have thermal pad built in. And there’s very limited options available at the moment. You have to use custom MCPCB like VirEnce or Djozz board. The easiest way is to find board designed for 119A. Then you need to scrape off the solder mask to widen the pads. I haven’t seen 119A boards for triple too.
Triple 144A would require 18V - driver problem
144A is already 4 x 219C crammed together. You should get approximately the same output with quad 219C.
The most benefit of 144A over 219C is higher max output, simpler single optic source point, higher quality light above 4000K region. It has fatter (almost 40%) spectrum in 480nm region, the area most cool white LED lacking
