I bought mine from Andrew & Amanda. Tested with Texas Ace Lumen Tube calibrated with Maukka lights and a Sekonic Spectromaster C-800-U. Lumen measurements taken at 2 seconds from turn-on.

Acebeam K75 Power Mode Turbo 4,310 lumens 6809K -0.0047 DUV 69.9 CRI -9.9 R9 44.4 R12 63 Rf 97 Rg
Acebeam K75 Power M4 1,538 lumens 5755K 0.0034 DUV 66.9 CRI
Acebeam K75 Power M3 778 lumens 5480K 0.0074 DUV 66.7 CRI
Acebeam K75 Power M2 247 lumens 5098K 0.0131 DUV 66.1 CRI
Acebeam K75 Power M1 128 lumens 4981K 0.0151 DUV 66.3 CRI
Acebeam K75 Eco Max 1,820 lumens



The turbo mode with a -0.0047 DUV looks beautiful pure white. The lower modes with positive DUV has a greenish tint.
