400v lighting technology is being used widely across the horticulture industry, preferred because of the additional IR and UV radiation when compared to traditional 230v technology.

Generally considered to produce 10% more PAR and increased intensity, these 1000w 400v dual spectrum lamps last longer than traditional 230v HPS lamps. These will only need changing every 12 months to keep a good quality of intensive growing light.

These 1000w Double-Ended (D/E) 400v blubs emit more UV and IR light than traditional single-ended HPS lamps.
