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.
