Seems like Emisar uses the same glass as the UCL lens. I tested all of Emisar lights to see negligible DUV differences between w/ glass and w/o glass. The light gets super hot much faster than the two FW3A SST-20 4000K I have. I really like this light and I think it would have been perfect if it had 8x7135 like the FW3A instead of 1x7135.
On turbo, the mixed tint appears very rosy, similar to my E21A Tiara Pro with 2x3000K and 2x4000K, but at similar outputs the E21A Tiara is noticeably rosier. Overall I really like this light and emitter configuration.
I can’t tell if the SST-20 4000K is the FD2 or FB4 tint bin since I can’t measure it without the 3000K. However, setting it to similar low output levels and comparing the emitter color with the FW3A, they look near identical. I hope someone can measure the SST-20 4000K to confirm which bin it is.
For my measurements with the FW3A, see
