A 4 ft, 4-lamp T5 grow light for veg and propagation
The fixture runs four 6500K InterLux T5 HO lamps across a 4 ft body for about 216W and roughly 20,000 lumens. That cool, blue-leaning spectrum suits seedlings, clones, and vegetative growth over a wide bench. T5 output runs cool, so you can drop the fixture close to the canopy without heat stress. Growers use the dual switches to run two lamps for seedlings, then all four as plants fill in.
Switching and mounting on the LuxStar T5 fixture
Dual power switches let you run half the lamps for a 50% output step, matching light to each growth stage. Digital ballasts drive the lamps efficiently, and the 17-pound aluminum body mounts overhead, vertical, or horizontal. At 47 x 16 inches, it covers a broad footprint. One note: this is a 6500K T5 fixture for veg and propagation, not a flowering light.
