HSTL features static white in a single channel and a color option (red, amber or green) in a second channel dually-controlled, and can be used across in surgical suites, clean rooms and exam or procedure spaces. Available with up to 10,000 lumens in the 1x4, 12,000 lumens in the 2x2 and 30,000 lumens in the 2x4, HSTL has two distribution options: asymmetric and symmetric.
