Rapid LED’s Green LED Puck (530nm) is a compact 9 W supplemental module for horticulture and DIY fixtures. It concentrates green output around 530 nm using Cree XP‑E2 Green emitters and an onboard Mean Well LDD‑700LS constant‑current driver. The board runs on 12 V DC and accepts optional 2.5–6 V PWM dimming. Measuring 67 × 67 mm, it mounts via 35 mm or 50 mm hole spacing and connects with a 5.5 mm OD/2.5 mm ID DC jack. Rapid LED recommends 1–2 pucks per 4 × 4 ft area, making it suitable for canopy penetration or low‑impact night viewing without disturbing dark periods. An optional Carclo 10613 lens and mounting bracket are available, and no separate heatsink is required.
