NextLight 150h 150W Full Spectrum LED Grow Light

The NextLight 150h is a compact, high-efficiency full-spectrum LED grow light built for smaller indoor growing spaces and grow tents. Drawing just 150 watts, it produces 390 µmol/s PPF at an efficacy of 2.6 µmol/J, combining strong output with a compact 15” × 15” footprint.

• Power: 150W
• Output: 390 µmol/s PPF
• Efficacy: 2.6 µmol/J
• Coverage: Up to 3’ × 3’

Designed for use throughout the growing cycle, the 150h provides a 2’ × 2’ high-intensity footprint and up to 3’ × 3’ of vegetative coverage, making it an excellent fit for compact gardens where efficiency and space matter.

390 µmol/s From Just 150 Watts

The 150h delivers 390 µmol/s PPF from 150W, reaching 2.6 µmol/J system efficacy. Its efficient design produces just 515 BTU/hr, reducing the heat load associated with older lighting technologies.

2’ × 2’ Flower / 3’ × 3’ Veg Coverage

The 150h is rated for a 2’ × 2’ high-intensity footprint for flowering and up to a 3’ × 3’ vegetative footprint.

Full-Spectrum White Light

NextLight’s bright white full spectrum is designed to support plants throughout the growing cycle, so one fixture handles everything from early growth through later high-intensity stages. Its natural-looking white output also provides excellent visibility when inspecting plants and working inside the growing area.

0–100% Onboard Dimming

An integrated dimming dial provides continuous 0–100% intensity control, giving significantly more flexibility than fixed-output lighting. Light levels can be reduced for younger plants and gradually increased as greater intensity is required.

Compact 15” × 15” Design

At only 15” × 15” × 3” and 6 lb, the 150h packs substantial output into NextLight’s most compact Home Series fixture.

Recommended Hanging Distance

NextLight recommends keeping at least 12 inches between the bottom of the fixture and the plant canopy.

Passive Cooling

The 150h uses passive cooling for quiet, fanless operation with no active cooling components.

IP65 Wet Rated

An IP65 wet rating makes the fixture suitable for damp horticultural environments.

Long-Term Reliability

With a Q90 life rating of more than 50,000 hours, the 150h is designed as a long-term lighting solution rather than a fixture requiring regular lamp replacement.

Choosing a Voltage Configuration

220–240V — ships with a 240V NEMA 6-15P power cord for 240V circuits (0.63A at 240V).

110–120V — ships with a 120V NEMA 5-15P power cord for standard 120V circuits (1.25A at 120V).
