The 400w Sunmaster Metal Halide Cool Deluxe Lamp has a lumen output of 32000 all of which is in the blue part of the spectrum making them ideal for vegetative growth creating plants with shorter internodes setting them on a course to heavy yields. The Sunmaster range of lamps has proven to be excellent value for money providing reliability and quality lamps time and time again. Horticultural lamp light output will decrease with use.
We recommend that growers replace lamps at regular intervals to maintain optimum yields. Note – As soon as lamps are switched on they will run extremely hot. Before handling, lamps should be switched off the ballast disconnected and allowed to cool down.
All high-pressure sodium and metal halide lamps need to be handled with care, avoid touching the lamp and particular care should be taken when using sprays or liquids around hot lamps as this may cause failure or explosion.
