Lumii Sun Blaster
The LUMii Sunblaster Dual Spectrum HPS offers exceptionally high output ? Couple this with raised spectral discharge in the reds and blues and a long lamp life, and you have the perfect plant grow light. Tube inflated crystal glass offers consistent thickness allowing more even light output. Available in both 400 and 600 watt, both have 32,000 life hours and colour temperature of 2000K. The 600w will output 155 lumens per watt, and the 400w output 140 lumens per watt. Spectral output changes in a HPS lamp as it ages. We recommend changing your lamp every 9-12 months for optimum growth conditions.
