GB 351D closed.

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.
