The last **groupbuy from Clemence was also for 219B V1 or?
Sorry I don’t know my LEDs what stand that V1 for?
I want to put them in the FW3A. As triple they should be good for 12A. Do I have a problem with a Samsung 30Q in TURBO?
I should somehow guess, better measure, the Amps.
Yes, I think all 219B’s still for sale are V1 versions, which are an upgrade of the original 219B but apparently not different enough to already be called 219C. The most significant difference as far as I noticed was a significantly lower Vf, but about the same output and same fairly low current handling.
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.
