Lumii Black HPS Bulb 400W,600W Hydroponics Grow Light
The LUMii SunBlaster lamp is available in two sizes – 400w and 600w. The 400w lamp gives an output of 140 lumens per watt (56000 lumens) and the 600w lamp gives an output of 155 lumens per watt (93000 lumens). The crystal glass used offers consistent thickness which allows a more even light output. There is raised blue levels in the spectrum output. The design of the lamp has avoided the use of barium film which means no blackening of the glass and less gas impurities in the lamp. It also allows for a cleaner more stable light output. The E40 mechanical double layer base design eliminates soldering and paste and delivers a 100% inline base.
