HLG 750 Diablo ES Enhanced Spectrum LED Grow Light

Struggling to deliver powerful, even light through a dense plant canopy? The HLG 750 Diablo ES is engineered to solve that exact problem. This professional-grade LED grow light uses revolutionary Enhanced Spectrum technology to provide more balanced energy and deeper penetration, ensuring your entire plant gets the light it needs for vigorous, full-cycle growth.

Designed for serious commercial cultivators, this system excels in grow tents, on flood tables, and over rolling benches. It’s built with four high-performance Diablo Quantum Boards and integrated reflectors, producing a massive 2089 PPF output with an exceptional photon efficacy of 2.86 µmol/J. The Enhanced Spectrum boosts green and deep red wavelengths, driving photosynthesis more efficiently and reaching lower growth sites that other lights miss. This fixture is a key part of the advanced Horticulture Lighting Group lineup, offering performance that stands out from competitors.

The HLG 750 Diablo ES provides a large 5' x 5' flowering footprint and a 6' x 6' vegetative footprint, with a reliable passive-cooled design that eliminates fan noise and maintenance.

FAQs

How does the Enhanced Spectrum technology improve plant growth?+

The Enhanced Spectrum boosts green and deep red wavelengths, which are highly efficient for photosynthesis. This specialized light penetrates deeper into dense canopies, activating lower leaves and promoting more uniform development throughout the entire plant. You can learn more about how HLG sets the bar for quantum board grow lights in our detailed article.

Is the HLG 750 Diablo ES suitable for my grow space?+

This light is perfect for a 5' x 5' flowering area or a 6' x 6' vegetative space. It's an ideal choice for standard grow tents, flood tables, and commercial rolling benches. For larger areas, multiple units can be used to create seamless, high-intensity coverage.

What maintenance does this light require?+

Thanks to its passive-cooled design, the HLG 750 Diablo ES is virtually maintenance-free. There are no fans to clean or replace. Simply wipe the diodes occasionally with a soft, dry cloth to ensure maximum light output. The solid-state design means no bulbs to change, ever.

Can I dim the light and control multiple units?+

Yes, the included power supply is fully dimmable, allowing you to adjust power from 0-730 watts to match your plants' growth stage. For advanced control of one or more lights, it is compatible with the HLG Growflux Access Point Controller (sold separately), which enables wireless scheduling and management.

How does the integrated reflector system work?+

The reflectors are engineered to capture and redirect light that would otherwise escape, focusing it down onto the plant canopy. This significantly improves PPFD uniformity across the entire footprint, ensuring plants at the edges receive as much light as those in the center for more consistent yields.

What are the electrical requirements for this fixture?+

The HLG 750 Diablo ES features a wide input voltage range of 120-277 VAC, making it compatible with nearly all residential and commercial electrical systems without needing extra equipment. It draws approximately 6.1 amps at 120V or 2.6 amps at 277V.
