Reflex F is a 4-foot LED bar from Cirrus LED Grow Lights designed for flowering. It draws 105 W and uses 56 proprietary 3 W diodes in a red-heavy spectrum. Intended as supplemental lighting or as a primary flowering solution when multiple bars are used in series, its recommended primary coverage is about 4 ft × 1.5 ft at 18 inches above canopy, with supplemental reach up to roughly 4 ft × 4 ft depending on height. The aluminum fixture measures 120 × 7.6 × 9 cm, weighs about 4.1 kg, and features 120° optics, UL rating, and 110–277 V input. Diode lifetime is cited at 50,000 hours, and adjustable brackets allow ~140° rotation for aiming.
