APEXstrip 660 LD is Crescience’s hyper‑red LED module designed to extend flowering spectra in modular grow builds. The 480 x 20 mm strip carries four Osram Oslon Optimal GH GSBRM4.24 diodes with a batwing optic to widen lateral light spread. It is intended for constant‑current operation and connects via a WAGO 2060 spring clamp. Typical efficiency is up to 3.8 µmol/J at 700 mA, with a maximum drive current of 1.4 A. The module delivers up to 42 µmol/s PPF at up to 12 W, allowing multiple strips to be combined for custom fixtures. Physical data include approximately 0.04 kg weight and a height around 6.5 mm. Coverage is configuration‑dependent but is around 60 x 25 cm.
