ISH150 Eclipse is a 150 W, UK-made LED grow light from Invisible Sun designed for small flowering areas. The fixture uses a Mean Well 150 W driver and the brand’s ISH576R board populated with 576 Samsung LM301H Evo white LEDs plus 16 Samsung LH351H V3 660 nm deep‑red diodes. It is fully dimmable, rated for a minimum 60,000‑hour lifespan, and targets a 2 ft × 2 ft flowering footprint (up to 80 × 80). Invisible Sun quotes an efficacy of about 3.0 µmol/J and provides PAR maps showing average PPFD around 878 µmol/m²/s at 16 inches. The Evo update adds a 435 nm blue spike for higher PPE and maintains optional conformal coating for water resistance. Dimensions are 250 × 350 × 90 mm.
