If you have time for this I could send you 2200k , current bin of 351D 4000, and new bin of 351B 3000k and 351D 5000k 90cri for testing.
Finally
5000k?
Part number breakdown for those who are curious. The order code will typically have the last six digits F4RTS6, which covers a relatively broad range of forward voltage, color temperature, and output ratings.
There is also a reel specific code that refines those last 6 digits: F2R1S2
F2 = 2.8-3.0V (good)
R1 = Tint bin straddling the BBL, 5000-5300K (good)
S2 = 380-400 lumens at 1050mA (fair)
Specs sound good.
I try to test led with reflector and frosted lens to mix everything
CCT = 4830K (Duv 0.0025)
Color Rendering Index (Ra) = 91.1 [ R9 = 56.1 ]
R1 = 91.5 R2 = 92.5 R3 = 92.9 R4 = 92.5 R5 = 91.2 R6 = 89.6 R7 =
93.9
R8 = 85.0 R9 = 56.1 R10 = 82.2 R11 = 92.9 R12 = 72.3 R13 = 91.6 R14 =
96.6
without reflector Duv changes from –0.007 in center to 0.007 at edges.
Hi Andrey,
Are you still planning to offer LH351D 3.000K 90CRI? I would be very much interested into some of these, e.g. for a nice triple individual of 3.000K/4.000K/5.000K. :-)
Cheers, Thomas
Hi , Thomas
When I sold all 4000K and 5000K I will try 3000k)
When you planned send 5000k?
I can begin to send at Monday. But it takes to send PMs.
i sent but without respond
Hi Andrey,
What are the chances to get some LH351D 5.000K 70CRI with better bin than W6 and/or some LH351D 5.700K 70CRI?
Thank you for the measurement. This result is resembling to a Nichia 219C of the same CCT regarding Ra (R9 could be a bit better, R2, R3, R13, R14 seems to be marginally weaker, R12 is marginally better) - which is a good result considering, that LH351D has better efficacy, than 219C.
What current did you use for the measurement?
Sent two message without your respond.
I decided to give up buying from you.
I’m sorry I was on a business trip then I was sick.
