I received some more 5000K from Convoy and they are not as good as the ones I got previously, before they were around duv 0.0020~0.0030 at 100mA, now around duv 0.0035~0.0050, It makes me wonder if its the same reel as before or a new one with a different color bin, this is quite disappointing.
I got some 5700K too, but there have been a mistake because they test the same as the 5000K.
Here is another one 2700K from Sofirn to compare with contactcr one, same beaded TIR as before (same distance, so lux can be compared) :
0.1A Ambient = 1726.1 Lux, CCT = 2701K (Duv 0.0013)
Color Rendering Index (Ra) = 95.9 [ R9 = 74.5 ]
IES TM-30-15 Rf = 94.10 Rg = 99.50
0.5A Ambient = 6778.6 Lux, CCT = 2714K (Duv 0.0010)
Color Rendering Index (Ra) = 95.5 [ R9 = 73.0 ]
IES TM-30-15 Rf = 94.00 Rg = 99.99
1A Ambient = 12251.9 Lux, CCT = 2722K (Duv 0.0007)
Color Rendering Index (Ra) = 95.1 [ R9 = 71.5 ]
IES TM-30-15 Rf = 93.61 Rg = 100.34
2A Ambient = 21058.3 Lux, CCT = 2720K (Duv –0.0003)
Color Rendering Index (Ra) = 94.5 [ R9 = 68.4 ]
IES TM-30-15 Rf = 92.71 Rg = 100.80
Sliced 1mm :
0.1A Ambient = 2298.4 Lux, CCT = 2435K (Duv –0.0013)
Color Rendering Index (Ra) = 96.0 [ R9 = 74.0 ]
IES TM-30-15 Rf = 93.27 Rg = 101.86
0.5A Ambient = 9113.0 Lux, CCT = 2448K (Duv –0.0016)
Color Rendering Index (Ra) = 95.5 [ R9 = 72.0 ]
IES TM-30-15 Rf = 92.54 Rg = 102.25
1A Ambient = 16433.9 Lux, CCT = 2459K (Duv –0.0019)
Color Rendering Index (Ra) = 95.1 [ R9 = 70.2 ]
IES TM-30-15 Rf = 91.87 Rg = 102.53
2A Ambient = 28013.9 Lux, CCT = 2464K (Duv –0.0027)
Color Rendering Index (Ra) = 94.3 [ R9 = 66.6 ]
IES TM-30-15 Rf = 90.77 Rg = 102.79
