AgroMax BIAX F55T5 Finisher Bulb – 10000K is a 55-watt compact T5 (PLL/BIAX) fluorescent lamp designed to fine-tune spectrum at the end of bloom or to boost blue during veg. It uses a 2G11 four-pin base and has a nominal length of 20.7 inches, fitting AgroMax PLL 55-watt BIAX fixtures and compatible housings like Tek Two/Tek Four. The 10,000 K color temperature delivers an ultra-blue, daylight-like output, rated at approximately 5,000 lumens per bulb, and the lamp carries a 20,000-hour life expectancy. Typical applications include supplemental use alongside warmer lamps to balance spectrum for compact growth and finishing runs. Because footprint depends on the host fixture and reflector, users should confirm placement and hanging height to achieve desired PPFD and uniformity.
