Light your entire 5x5 canopy with 2089 PPF and zero fans to fail
The HLG 750 Diablo ES draws up to 730 watts to produce 2089 PPF at 2.86 µmol/J, putting it among the highest-output single fixtures you can hang in a 5'x5' tent. Four Diablo Quantum Boards with integrated reflectors spread light evenly across the entire flowering footprint, and the Enhanced Spectrum (ES) adds green and deep red wavelengths that penetrate dense canopy layers where standard white LEDs fall off. Passive heatsink cooling means no internal fans, no noise, and no moving parts to replace.
- Efficacy typically 2.0 to 2.5 µmol/J, higher electricity cost per photon
- Standard white spectrum with minimal deep red, weak lower-canopy penetration
- Single-bar or spider designs with uneven PPFD and center hot spots
- Active fan cooling adds noise and creates a failure point
- 1 to 3 year warranty, limited or no commercial certifications
- Basic dimming knob only, no daisy-chain or wireless option
- 2.86 µmol/J efficacy, more light per watt means lower electricity bills
- Enhanced Spectrum boosts green and deep red for full-canopy penetration
- Four Quantum Boards with integrated reflectors for even PPFD edge to edge
- Fully passive cooled, zero noise, no fans to fail
- 5-year warranty, UL 8800 and CSA listed for commercial compliance
- RJ 0-10V daisy-chain dimming with optional GrowFlux wireless control
Enhanced Spectrum (ES) 43:38:19 R:G:B
The ES spectrum pushes more energy into green and deep red wavelengths compared to standard white LEDs. Green light penetrates deeper into leaf tissue and through upper canopy layers, reaching sites that red and blue alone miss.
2089 PPF at 2.86 µmol/J 730W
At full power, the fixture converts 730 watts into over 2000 µmol/s of usable light. Over a 12-hour flower cycle, that is about 8.76 kWh per day, which is significantly less than competing fixtures with lower efficacy ratings at the same output.
Integrated Reflectors on All 4 Boards
Small reflectors built into each Quantum Board redirect photons downward and outward, increasing PPFD uniformity at mid and lower canopy levels without requiring a separate reflector hood.
Passive Heatsink Cooling
Aluminum fins dissipate heat without fans, so there are no bearings to wear out and no noise. The fixture runs warm to the touch but keeps radiant heat low at the canopy level.
0-100% Dimming with RJ 0-10V
The included driver dims from zero to full power via a manual knob. For multi-light rooms, you can daisy-chain the RJ signal or add a GrowFlux Access Point for wireless control from your phone.
Full-Cycle Veg Through Flower
The ES spectrum is designed for the entire grow cycle. Run it at 40-50% for veg in a 6'x6' footprint, then ramp to full power for flower in a 5'x5'. No spectrum swap, no second fixture.
Setting up your HLG 750 Diablo ES
Hang the fixture
Use the included ratchet hangers or fixed hooks. For flowering, position the light 15 to 24 inches above the canopy. For veg, raise it to about 36 inches and dim to 40-50%.
Connect power
The included cord works on 120V or 240V circuits. Plug in, and the light powers on at the last dimmer setting. No warm-up time, no external driver box.
Set your intensity
Turn the manual dimmer knob to your target output. For seedlings and fresh transplants, start around 30%. Increase gradually as plants acclimate to the higher PPFD.
Daisy-chain or go wireless
For multi-light rooms, connect fixtures via RJ cables to dim them all from one knob. Or add a GrowFlux Access Point (sold separately) to control intensity from your phone.
