The SL150IIIBI Bi-Color LED Monolight from Godox is a sophisticated light source with a full range of professional features. Color temperature ranges between 2800–6500K and it has high CRI/TLCI ratings of 96/97 to indicate accurate color reproduction. The light intensity is variable from 0 to 100% and while you can make adjustments locally on the fixture you can also make them from distances up to 164' with an optional radio remote or from up to 98' away with your smartphone and the Godox app. The fixture is kept cool by two quiet fans that can be turned off in sound-sensitive situations.
