Rapid LED’s Exotic Supplement Booster Board is a two-channel UVA + infrared add-on designed to round out spectra that standard white grow lights often lack. The board integrates 9 SemiLEDs UVA diodes (390–400 nm) and 9 SemiLEDs IR diodes (840–870 nm) driven by two onboard Mean Well LDD-700LS modules. It connects via a 5.5 mm/2.5 mm DC barrel and WAGO dimming block, and supports optional 2.5–6 V PWM control; without a controller both channels run at 100%. Typical power draw is about 35 W and one board is specified to cover a 2' × 4' area. The PCB measures 974 × 47.5 mm (~38.5 × 1.9 in) and can be mounted on the Rapid LED Supplemental Canopy Heatsink for added rigidity or canopy integration.
