A 6400K T5 grow light for seedlings and veg
The 3 ft fixture runs a single 39W 6400K T5 HO lamp. Its cool spectrum peaks at 435 and 615 nm, keeping seedlings and clones compact. It puts out about 2450 lumens across a 103-degree spread. A built-in electronic ballast gives instant, flicker-free starts, and the self-cooling aluminum housing runs cool enough to sit inches off the canopy. Growers line these across a prop bench for even light on trays.
Why the T5 HO strip light suits a propagation shelf
Up to 8 fixtures link on one power cord, so a full bench runs from a single outlet. The 6400K lamp is rated to 10,000 hours, and the aluminum housing resists dust and splash on a wet bench. Each lamp weighs only about 100 g, so mounting is light work. Note this is a 6400K T5, tuned for propagation and veg, not a bloom light.
