ok so, update… ordered a new driver, MCPCB and 8 of the Samsung LH351D 4000K 90CRI…
shame i coulden’t use the N219s but… live and learn, right lol
tnx everyone for the assist, i’ll update again once the new parts arrive.
:::Edit::: On another note, has anyone dedomed a Samsung LH351D 4000K 90CRI yet? If so, resaults?
Not dedomed, I sliced a few. After slicing close to the phosfor I sanded the surface with very sand paper. The result is 20% light loSs, 3400K end colour temp, 93CRI and a very very good tint. The 20% loss is more than average, I wonder if it would be less if I did an even better polishing job.
Single emitter lights, the beam is very good. The only big disadvantage is the light loss, the lh351d is found to be a realtively efficient high CRI led, you loose that advantage.
What is the recommended method for Q8 spring bypass when the light is used reasonably often? I just added some solder blobs at the top and bottom and ran short 22AWG leads between them.
