Luminus SBT-90 gen2 5700K tested (SBT-90-WDS-F72-SA600 SA-H4, from Neal)

I placed a small smooth reflector on top of the bare led that made a decent hotspot on my ceiling. I measured the tint of the hotspot at 4 currents.

current CCT duv CRI
0.1 A 5100 K +0.0164 67
0.5 A 5140 K +0.0152 67
2 A 5270 K +0.0122 67
10 A 5620 K +0.0061 67

The colour temperature is fairly neutral, at lower currents even significantly lower than Neal listed, and despite the high duv at lower currents I do not judge the tint as disturbingly green. The tint at 10 A looks quite perfect.
