Reflex UVB is Cirrus LED Grow Lights’ 4-foot supplemental UV fixture designed to add targeted UV to existing HID, HPS, or LED setups during late flower. The bar draws 105 W and uses 56 three‑watt diodes behind a 120° optic to deliver a UV‑heavy spectrum intended for resin stimulation. Typical coverage is about 3 × 4 ft when mounted 24–36 inches above the canopy. The aluminum and tempered‑glass housing is built for horticultural environments, and the unit accepts 110–277 VAC. Dimensions are 48 × 3 × 3.5 inches, with a listed weight of approximately 9 lb and an LED lifetime around 50,000 hours. This model is part of Cirrus’s Reflex series (F, V, and UVB variants).
