Most reflectors rely on overlap for uniformity. This is best practice as it also guarantees the best possible horizontal penetration of your crop. As a result though, the light uniformity under a single reflector is not optimal.
The M 100 DE SR (Singe row / Small Room) reflector from Gavita is specifically designed for configurations where you have a single, or single row of reflectors in one room. With a spread of 6ft/180 cm and a width of about 4ft/110cm it can provide you not only with high light levels but also an extremely high uniformity of over 90%! The reflector is suitable for 1000W or 750W double ended lamps and fits all Gavita DE fixtures.
