AgroMax BIAX F55T5 Bloom Bulb – 3000K is a 55-watt compact T5 (PL‑L) fluorescent lamp for horticultural flowering phases. It uses a 2G11 four-pin base and measures 20.7 inches long. Output is rated at approximately 5,000 lumens per bulb with a warm 3000 K spectrum suited to bloom, and typical service life is 20,000 hours. The F55T5 format folds a standard 4-foot T5 into a parallel twin-tube design to concentrate light in smaller fixtures. The bulb fits AgroMax PLL 55‑watt BIAX fixtures and other compatible 55W PL‑L housings (e.g., Tek Two/Tek Four) and includes a one-year warranty from AgroMax. Coverage depends on the reflector and fixture geometry; consult the specific fixture’s specification for footprint and hanging height.
