The AgroMax Pure PAR Veg T5 Bulb is a 4‑foot high‑output fluorescent lamp designed for vegetative growth. Using a specialized phosphor blend, it concentrates light in the blue (~420–470 nm) and red (~620–670 nm) bands associated with chlorophyll production, creating the product’s distinctive purple output. It is the standard F54T5HO format with a G5 mini bi‑pin base and draws 54 watts, fitting all compatible 4‑ft T5‑HO fixtures. Actual tube length is approximately 45.75 inches. In typical use, a single 54‑watt 4‑ft T5 covers about a 4 ft by 1.5 ft strip when placed close to the canopy and used with a reflector. This bulb serves as a straightforward replacement for T5HO fixtures used with clones, seedlings, vegetative plants, and mother stock.
