FAQs

What is the ideal hanging height for this light?+

For flowering, the recommended hanging height is 15" to 24" above the plant canopy. For vegetative growth, a height of 36" is ideal to cover a larger 6' x 6' area.

Is this light powerful enough for a 4'x4' tent?+

Absolutely. The HLG 750 Diablo is designed for a 5'x5' flowering footprint, so it will provide more than enough high-intensity, uniform light for a 4'x4' tent, ensuring maximum yields and density.

What's the difference between the HLG 750 Diablo and the Scorpion Diablo?+

Both lights use the same high-efficiency Diablo Quantum Boards. The main difference is the form factor. The HLG 750 Diablo has a more compact, rectangular design, while the HLG Scorpion Diablo has a wider, six-bar design for broader coverage in specific setups. The choice depends on the shape and needs of your grow space.

How does this compare to a 1000W HPS light?+

The HLG 750 Diablo is designed to replace and outperform a 1000W single-ended HPS light. It consumes less power (715W vs. 1000W+), produces significantly less heat, has a more optimized full spectrum for plant growth, and has a much longer lifespan with minimal light degradation.
