Product Details

The CMH luminaire’s ultra low-profile design and low radiant heat output, lends itself ideally to vertical applications or in horticultural facilities where ceiling height is limited.

Ceramic Metal Halide (CMH) delivers a highly stable, well balanced light spectrum―similar to natural daylight―providing a broad spectrum of wavelengths (including UV), so the plant can absorb exactly what it needs. The spectrum is ideal for vegetative growth cycles; or supplementary blue light in HPS flowering rooms.

The luminaire produces low radiant heat, allowing for close-to-crop mounting and reduced BTUs―resulting in reduced AC costs.
