Top of the EVO line, the EVO 6-150 carries 400 watts on a 150 cm fixture and puts out 1090 micromol per second. It floods a long, dense bed with light from a single panel, which keeps a heavy fruiting crop cropping evenly end to end.
The 90 degree lens directs that output downward, not at the walls. Passive cooling keeps it silent and free of fans to fail. Efficiency stays above 3 micromol per joule, and it ships with IP65 sealing and a 3 year warranty. Order the connection cable separately.
