Power draw is 240 W, delivering a quoted PPF of 706 µmol/s and a fixture efficacy around 2.94 µmol/J. Coverage is specified for 2×4 ft or 3×3 ft spaces, and the passively cooled board measures 700×300×40 mm. The unit is fully dimmable, controller compatible, and rated IP64 for water resistance. Invisible Sun highlights spectrum tuning with a short-wavelength blue peak at 435 nm and deep red at 660 nm to support horticultural performance while maintaining efficient, uniform output.
