HLG 100 Rspec Full Spectrum LED Grow Light

The HLG 100 Rspec Full Spectrum LED Grow Light is a compact 95W fixture designed for both vegetative growth and flowering. It pairs high-efficiency Samsung white LEDs with dedicated deep red diodes to deliver a full-cycle spectrum from a lightweight, passive-cooled Quantum Board® design.

The fixture uses 176 Samsung LM301H full spectrum LEDs plus four LH351H V2 660nm deep red LEDs, producing 220 PPF at a rated efficacy of 2.41 µmol/J.

• Power: 95W
• Output: 220 PPF
• Coverage: 2’ x 2’ Flower / 3’ x 3’ Veg
• Diodes: Samsung LM301H + Deep Red 660nm

Full Spectrum for Veg & Bloom

The HLG 100 Rspec is designed for both vegetative and flowering stages.

Its Samsung LM301H white LEDs form the foundation of the spectrum, while dedicated 660nm deep red LEDs supplement the output for flowering.

220 PPF from 95 Watts

Despite its compact footprint, the HLG 100 Rspec produces 220 µmol/s PPF while drawing only 95 watts.

2.41 µmol/J Efficacy

The efficient Quantum Board® design delivers a rated system efficacy of 2.41 µmol/J, putting out high photon output per watt.

2’ x 2’ Flower Coverage

HLG rates the fixture for a 2’ x 2’ flowering footprint when positioned approximately 12–18 inches above the canopy.

3’ x 3’ Veg Coverage

For vegetative growth, coverage expands to 3’ x 3’ at 18–24 inches above the canopy.

Samsung LM301H + Deep Red LEDs

The diode configuration consists of:

• 176 Samsung LM301H Full Spectrum LEDs
• 4 Samsung LH351H V2 Deep Red 660nm LEDs

This combination gives the Rspec its full-cycle spectrum while keeping the efficiency and compact footprint of HLG’s Quantum Board® platform.

Passive-Cooled Design

The HLG 100 Rspec uses passive thermal management with no integrated cooling fans, for quiet, low-maintenance operation.

Compact, Lightweight Fixture

The fixture measures just 12.75” x 11” x 2.5” and weighs approximately 3 lb, making it easy to integrate into smaller indoor growing spaces.
