Invisible Sun’s ISH530 Pro is a 530 W full‑spectrum LED fixture designed for a 1.2 × 1.2 m (4 × 4 ft) flowering footprint. The Pro variant uses Samsung LM301H white LEDs with LH351H deep reds and is driven by a Mean Well HLG‑480H‑C2100A driver. Factory data lists fixture efficacy at 2.61 µmol/J, with chassis dimensions of 70 × 60 × 4 cm. Invisible Sun’s release notes confirm coverage and draw for the ISH530 range, available in Pro and Type R configurations; retailer specifications for the ISH530 V2 match these figures and provide an average PPFD of about 886 µmol/m²/s. The ISH530 Pro ships fully assembled with ratchet hangers and a 3 m power cable for straightforward installation.
