Invisible Sun’s ISH100 R / BR is a compact 100‑watt‑class LED grow light for small spaces and propagation. The Evo generation uses Samsung LM301H Evo whites with supplemental 450 nm blue, 660 nm deep red and 730 nm far‑red diodes, driven by a Mean Well driver and controlled via an external dimmer with daisy‑chain support. The 270×270×40 mm panel is specified for 1.5×1.5 ft optimal flowering coverage (up to 2×2 ft maximum). Power draw is adjustable from 0 to 110 W at the wall (earlier BR units were rated to ~90 W). Spherical‑test efficiency is stated at 2.7 µmol/J, with average PPFD reported around 446 µmol/m²/s. Manufactured in the UK with CE/ROHS compliance, the unit targets seedlings, clones, veg and full‑cycle use in tight footprints.
