The Ushio HiLux Ceramic MH lamps are available in 3,000K and 4,200K. Ceramic metal halide lamps are excellent for plant growth and HPS supplementation. Spectral distribution is optimized for photosynthetic efficiency. Blue output for healthy plant growth and robustness. Ceramic umol output within the PAR spectral range (Photosynthetic Active Radiation). Economical due to long average life, high umol output, low energy consumption.
