GlowR40

The Spider Farmer GlowR40 is a 40 W deep‑red supplemental LED light set designed to enhance flowering and fruiting. It includes two 20 W bars driving 72 LEDs that target the 650–665 nm band (peak ~660 nm). Each IP65‑rated bar measures 62.7 x 4.5 x 3.7 cm and the assembled set weighs about 0.9 kg. A digital programmable timer and daisy‑chain design support up to 16 bars on 110 V or 32 on 220 V for scalable installs. Bars can mount horizontally or vertically to fill shadowed zones or under‑canopy gaps and are typically paired with primary fixtures under ~500 W. Usable area is roughly 100 x 60 to 100 x 90 cm depending on height and placement. Rated lifetime is about 50,000 hours.
