FM320 is a 320 W bar‑style LED fixture offered by Rapid LED for small canopies and tent grows. Rapid LED’s own wattage guidance maps roughly 300 W to a 2 × 4 ft flowering footprint, which aligns with this model’s intended coverage. The OEM FM4 platform underpinning the FM320 uses LM‑80 rated OSRAM diodes, IP65 housing, and 0–10 V dimming. Dimensions are about 1193 × 536 × 50 mm with a weight near 6.6 kg. Available spectrums typically include a 4000 K full‑spectrum option for veg/full‑cycle and a warmer option for flower. L70 service life is rated around 78,000 hours.
