The HLG 750 Diablo ES Enhanced Spectrum LED Grow Light combines high-output Diablo technology with HLG’s Enhanced Spectrum (ES) for full-cycle indoor cultivation.
Four Diablo Quantum Boards® produce 2,089 PPF at an efficacy of 2.86 µmol/J. The ES spectrum increases energy in the green and deep red portions of the spectrum, while integrated reflectors improve photon delivery throughout the canopy.

- Spectrum: Enhanced White + Deep Red
With a 5’ x 5’ flowering footprint, a 6’ x 6’ vegetative footprint, dimmable output and passive cooling, the 750 Diablo ES is built for high-intensity indoor growing from vegetative growth through flowering.
HLG Enhanced Spectrum
The defining feature of the 750 Diablo ES is HLG’s Enhanced Spectrum technology.
This plant-centric spectrum increases green and deep red output for a broader spectral distribution, designed for full-cycle cultivation and improved light penetration through dense canopies.
43:38:19 Red:Green:Blue Ratio
The Enhanced Spectrum is balanced at a 43:38:19 Red:Green:Blue ratio, giving a more even distribution of red, green and blue wavelengths than a conventional white-plus-red fixture.
Four Diablo Quantum Boards®
Four high-performance Diablo Quantum Boards® form the foundation of the fixture’s high output and broad coverage.
The multi-board layout distributes light across the growing area while maintaining the intensity a 5’ x 5’ flowering footprint requires.
2,089 PPF Output
The HLG 750 Diablo ES delivers 2,089 µmol/s of total PPF, putting more than 2,000 micromoles of photosynthetically active photons into the growing area every second.
That makes it a high-output single-fixture solution for larger indoor growing spaces.
2.86 µmol/J Efficacy
With a system efficacy of 2.86 µmol/J, the 750 Diablo ES pairs its high photon output with efficient electrical performance.
The result is more usable light per watt while keeping the intensity demanding indoor cultivation needs.
Integrated Reflectors
Integrated reflectors improve photon delivery by directing light downward and outward toward the growing area.
Combined with the four-board layout, the reflector system spreads PPFD throughout the canopy rather than concentrating output directly beneath the center of the fixture.
5’ x 5’ Flowering Coverage
HLG rates the 750 Diablo ES for a 5’ x 5’ flowering footprint at 15”–24” above the canopy.
Four Diablo boards, integrated reflectors and Enhanced Spectrum output together provide broad high-intensity coverage from a single fixture.
6’ x 6’ Vegetative Coverage
For vegetative growth, the fixture covers up to 6’ x 6’ at approximately 36” above the canopy.
Dimmable output lets intensity and power consumption be reduced when maximum flowering output is not required.
Dimmable Output
The HLG 750 Diablo ES includes a dimmable power supply with RJ 0–10V control and a manual adjustment knob.
Output can be adjusted for different plant stages, canopy requirements and growing environments.
Optional HLG 30 UVA Supplement
The 750 Diablo ES can be paired with the HLG 30 UVA Supplement, adding UVA wavelengths to the lighting system.
The UVA supplement is an optional add-on and is not included with the standard 750 Diablo ES fixture.
120–277V Operation
The fixture supports 120–277VAC at 50/60Hz, making it compatible with a wide range of residential and commercial electrical installations.
Passive-Cooled Design
The HLG 750 Diablo ES uses passive thermal management, eliminating integrated cooling fans.
With no fixture-mounted fans, the design runs silently and removes fan motors as a potential maintenance point.
