The Invisible Sun ISH FR8 is a supplemental far‑red LED strip designed to act as a flowering initiator. It provides 730 nm light for about 10–15 minutes at lights‑out to accelerate phytochrome reversion, helping plants enter night mode faster and potentially shortening overall flowering duration. The plug‑and‑play bundle includes the ISH FR8 strip, Mean Well LPC‑20‑700 driver, power cable, heatsink, hanging kit, and 24‑hour timer. Coverage is specified for a 4×4 ft area, with an actual power draw of 20 W. The strip uses eight far‑red diodes and Samsung’s LH351H 730 nm emitters. The PCB measures approximately 500 × 40 × 1.5 mm, making it easy to integrate alongside existing LED, HPS, or CMH fixtures without altering the main spectrum.
