GT FC40 vs 519A vs B35AM ???

I should add my comment about the wonderful beam color applies only to the 4500k CCT version of FC40. The “5000k-5500k” FC40 which I also have has a colder more daylight look as expected (measured CCT 5300k, Duv 0.0004). It is good but not the one I would recommend first.

Funny someone mentioned that. I measured my M21B FC40 5000-5500K yesterday, and the CCT was 5809K. A fair bit colder than it should be. I always thought it looked too blue, and the measurement confirms it.

I personally much prefer 4500k, but I bought FC40 5500k to see what it looks like as it has probably among the highest Ra and R9 for a 5500k LED.

I took these pictures to show progression of CCT and “blue.” The red bougainvillea on left side looks almost violet with the SFT40 6000k LED.

General question for all… In M21B, 519a vs GT FC40. 519a would output less lumens and have a more throwy beam than the GT, with more lumens and more floody beam. My question: which one would actually throw further.

If both are driven to their absolute max, the throw is comparable. If the 519A is dedomed, it throws farther.

At the same power input, the 519A handily beats FC40 in throw.

Just what I wanted to know.

Cheers!
