Feit Electric’s 17‑Watt E26 A21 grow bulb is a small-format LED for indoor horticulture that fits standard medium (E26) sockets. It offers three selectable spectra — blue, red/white/blue, and red — toggled on‑bulb or via a standard wall switch, covering seedling, vegetative, and flowering phases. Output is listed at 1600 lumens with PAR/PPF intensities of 24.1, 26.5, and 27.9 depending on spectrum. The non‑dimmable SMD LED bulb draws 17 W at 120 V, is damp‑location rated, and is specified for horticulture use. Rated lifetime is 15,000 hours. Physical size is approximately 12.7 × 6.9 cm (5 × 2.7 in). Feit’s grow‑light guidance places lower‑wattage bulbs like this 6–12 inches from the plant canopy for best results in compact setups.
