SST-20 is perfectly fine with me. I’m glad they’re moving forward. I’ve got some 4000K LH351D’s on hand to try if I don’t like the SST-20.
Relevant info for those who like to mod:
AED still has 5000K LH351D, 90 CRI emitters available. Djozz and Bob McBob have both verified that when dedomed, the Samsungs get warmer , throwier, and the Duv decreases (goes from slightly green to neutral or even slightly rosy).
Output does decrease, but the LH351D should still have an advantage, especially at high currents. If Djozz’s measured 19% lumen loss is typical, then adjusting the figures in the datasheets for common bins yields (emitter lumens, not OTF):
| CCT | 700mA | 3000mA | |
| LH351D S2 5000K sliced | ~4300K | 215 lumens | 692 lumens |
| SST-20 J4 4000K | 4000K | 193 lumens | 556 lumens |
The SST-20 should still have a bit better CRI and R9, and perhaps also slightly better throw.
