hey guys! The Bi spectrum light from mland is not in the purple spectrum it is seperated ( at least the newest version of it) into blue and red spectrum. There phosphorus coat is not too thick and does not influence the lumen strenght published from the manufacturer. I have tested these lights and they work really nice, no heat, really really low consumption ( think green) and on top of that you have a 5 year warranty. So they must be confident in their product when offering such a unusual long warranty!
Super Grow light (also known as induction lamp) relies on the fundamental principles of electro magnetic Induction and gas discharge to create lights. No electrodes and no filament to be damaged, its life time is up to 100000hrs, more than 100 times longer in comparison with incandescent lamp, 12 times compared with HPS,MH lights, 15 times compared with Fluorescent lamp and 2 times compared with LED grow lights.
We use the new technology to manufacture the super grow light to emit the best useful lights for the plants growth. The best growing result and super long light time at no cost for maintenance make the super grow light to be the best choice for the greenhouse growth.
The bi spectrum super grow light is ideal for all phases of plant growth, and works well with any indoor garden, whether hydroponics or soil based.
The low-frequency electrode-less Super grow light:
50W super grow light > 90W LED Grow light
150W super grow light > 250W LED Grow light
200W super grow light > 300W LED Grow light
300W super grow light > 450W LED Grow light
400W super grow light > 600W LED Grow light
