The EYE HORTILUX Ceramic Metal Halide (CMH) 315 grow lamp was designed specifically for horticulture. Most ceramic metal halide lamps were designed for use in the retail space, so the UV light was blocked. Hortilux uses a glass that allows the UV light to pass through, benefiting plant growth.

The EYE HORTILUX 315w CMH uses a PZGX18 (bi-pin) base; it is compatible with bi-pin PZGX18 fixtures only. Carefully install the lamp into the socket by inserting pins into matching shaped holes in socket and turning lamp clockwise or counterclockwise according to manufacturer instructions. When lamp is properly installed, the base will stop turning.

The exclusive EYE HORTILUX CMH spectrum provides 50% more ultra violet (UV) than the competitive lamps available today. This results in better overall plant growth and higher yields.


Traditionally, ceramic metal halide lamps were not designed for horticulture applications. They were designed to block UV when lighting products in retail stores. The EYE HORTILUX 315 grow lamp was engineered to allow safe amounts of UV to pass through the glass and better imitate a plant’s exposure to natural sunlight.
