It’s built to fit small grow stations, shelves, and window-side pots where precise directional light and energy savings matter. ETL listed and rated for long life, the lamp targets hobbyists, apartment gardeners, and plant parents seeking a reliable supplemental light source without bulky fixtures.\u003c\/p\u003e\n\n\u003ch3\u003eHow bright is this grow light and how efficient is it?\u003c\/h3\u003e\n\u003cp\u003eThe lamp produces strong usable light for plants with a PPFD measurement of about 402 μmol\/s\/㎡ at 1 ft, while consuming only 20W of electrical power — comparable to a small 300W incandescent output in plant-effective photons. That efficiency reduces running costs and household heat compared with older bulbs.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasured PPFD: ~402 μmol\/s\/㎡ at 1 ft for effective plant response\u003c\/li\u003e\n  \u003cli\u003ePower draw: 20W total (low energy use for continuous cycles)\u003c\/li\u003e\n  \u003cli\u003eEstimated significant electricity savings vs incandescent lighting\u003c\/li\u003e\n  \u003cli\u003eRated lifespan: ~25,000 hours for long-term use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat spectrum and coverage does it provide for different growth stages?\u003c\/h3\u003e\n\u003cp\u003eSANSI’s full-spectrum output spans approximately 400–780nm and delivers natural 4000K daylight with a CRI near 100, making foliage colors appear true-to-life while offering wavelengths useful across seedling, vegetative, and flowering phases.
