ISH 5R is a legacy Invisible Sun LED fixture assembled from the brand’s Type R strip modules. Each R Strip combines full-spectrum Samsung LM301H whites with Samsung LH351H deep‑red (660 nm) and far‑red (730 nm) diodes to support full‑cycle growth and Emerson effect control. Per the manufacturer’s strip specification, one R Strip draws about 59.85 W at 2100 mA; in ISH 5R the five‑strip configuration yields roughly 300 W actual draw depending on driver. Community guidance at the time suggested using two ISH 5R units to flower a 4x4 ft space, placing a single unit’s effective flowering footprint near 2x2 ft.
