Active Grow Integrated Dual T8 4FT LED Grow Light – Sun White Spectrum

The Active Grow Integrated Dual T8 4FT LED Grow Light is a lightweight, full-spectrum horticultural fixture designed for propagation, microgreens, leafy greens, herbs and other low-to-medium light applications.

• Power: 38W Actual Draw
• Output: 75 µmol/s PBAR
• Efficacy: 1.97 µmol/J PBAR
• Coverage: Up to 2’ × 4’

Drawing just 38 watts, the fixture produces 75 µmol/s PBAR output at 1.97 µmol/J and replaces traditional 100W fluorescent shop lights.

75 µmol/s PBAR Output

The fixture produces 75 µmol/s across the 280–800nm PBAR range at 1.97 µmol/J, and 70 µmol/s PPF across the 400–700nm PAR range at 1.84 µmol/J.

Sun White Spectrum

Active Grow’s Sun White Spectrum provides full-spectrum output across the PBAR range with a typical CRI of 95. The spectrum incorporates additional red and far-red wavelengths while maintaining natural-looking illumination that makes visual plant inspection easier.

Up to 2’ × 4’ Coverage

At 12 inches above the plant canopy, the fixture provides uniform coverage across approximately 2’ × 4’ for low-light applications.

For medium-light applications, Active Grow recommends approximately 18” × 4’ of coverage at a 9-inch hanging height.

Integrated Dual LED Design

Two LED tubes are built directly into the fixture for a simple, ready-to-use design. The integrated tubes are non-replaceable and paired with built-in reflectors to provide broad, uniform light distribution at close mounting distances.

Seamless Daisy-Chain Connectivity

Multiple fixtures can be connected using the included 2-foot daisy-chain cable or linked directly end-to-end using the supplied connector.

Active Grow rates the system for up to 12 fixtures at 120V, 20 at 208V, 24 at 240V or 28 at 277V on one circuit.

Water-Resistant Switch

A built-in rocker-style on/off switch features a protective cover against humidity and dust.

120–277V Universal Input

Universal 120–277V, 50–60Hz compatibility makes the fixture suitable for both home and commercial installations. An optional 240V plug adapter is available separately.

Low-Energy, Low-Heat Operation

The 38W LED fixture uses approximately 60% less energy than traditional fluorescent shop lighting, reducing both electrical consumption and heat output.

40,000-Hour Lifetime

Active Grow rates the fixture for 40,000 hours of operation.
