Ushio - HiLUX GRO 315W 4200K Ceramic Metal Halide Grow Lamp

Ushio HiLUX GRO 315W 4200K Ceramic Metal Halide Grow Lamp

Ushio HiLUX GRO CMH-315W/942/AGRO is a 315 watt ceramic metal halide grow lamp designed for growers who want the efficiency and plant quality of CMH lighting in a compatible 315W fixture. This is the 4200K version, offering a spectrum with strong blue output for healthy, compact growth and branching, while still providing red light for balanced plant development.

This lamp is a solid choice for growers replacing an existing 315W CMH lamp in a compatible fixture, especially when the goal is vigorous vegetative growth, strong structure, and high-quality plant development. It is also suitable for all-purpose growing where a cooler CMH spectrum is preferred.

Important: This is a replacement lamp only. It must be used with a compatible 315W CMH/LEC fixture using an ANSI C182/O ballast or compatible electronic ballast.
