Rapid LED’s Photo Red Flower Boost Puck (660nm) is a compact supplemental LED module designed to add deep‑red output during bloom. The puck draws 8.5 W and is built around Cree XP‑G3 Photo Red diodes driven by an onboard Mean Well LDD‑700LS constant‑current driver. It runs from 12 V DC via a 5.5 mm × 2.5 mm barrel connector and supports optional 2.5–6 V PWM dimming. The 67 × 67 mm board includes 35 mm and 50 mm mounting holes and can accept a Carclo 10613 optic and an optional mounting bracket; no separate heatsink is required. Rapid LED recommends using two pucks per 4' × 4' flowering area. The 660 nm wavelength targets chlorophyll A absorption for flowering‑phase supplementation.
