I modded a floodlight by swapping out the original cool white LED with the (supposedly) 90 CRI, 5000k CCT I bought from alibaba for use as an improvised desk lamp.
Modding in action. The original LED (bottom right) is 20w where the new one (wired) is 30w. I’m actually under-driving the one I used for replacement, but that’s okay. 20w is plenty bright for an improvised desk lamp.
Some cactus shot under the modded light. Does this looks like 90 CRI to you?
The LED used for modding. I had 4 of them in my possession. One used in this project, three to go.
