A 4 ft 6400K T5 grow light for propagation and veg
The 4 ft fixture runs a single 54W 6400K T5 HO lamp, covering more bench than the shorter models. Its cool spectrum peaks at 435 and 615 nm, holding seedlings and veg plants tight and compact. Low heat from the self-cooling aluminum housing lets you run it a few inches off the canopy across a 103-degree spread. Growers line 4 ft fixtures over long propagation benches where a 3 ft bar would leave gaps.
Why the 4 ft T5 HO strip light covers more bench
The extra length puts even 6400K light across a full 4 ft run, so trays at the ends are not shorted. Up to 8 fixtures link on one power cord to wire a whole rack from a single outlet. The aluminum housing resists dust and splash. Like the rest of the line, this is a veg-and-propagation T5 at 6400K, not a bloom light.
