Ultra-Powerful Delivering Up to 1500 Watts, 8 Diablo Quantum Boards, 2 Drivers, and Dual Zone Dimming for Commercial-Grade Growth

Maximize yields with this powerful LED grow light delivering 4178 PPF and 2.86 µmol/J for pro-level grow rooms.

The HLG Scorpion Ultima Diablo delivers industry-leading performance with its 4178 PPF and 2.86 µmol/J efficacy, using 8 high-output Diablo Quantum Boards. Built for high-intensity applications, this LED light excels in tents, flood tables, vertical racks, and rolling benches, any setup where power and uniformity matter.

Is it energy efficient?

Absolutely. With a photon efficacy of 2.86 µmol/J, it crushes any premium HPS fixture. For comparison, even high-end DE HPS tops out around 2.1 µmol/J. You’re getting more usable light per watt, and that means lower power bills and higher output.

Best applications

  • Large flowering bays four by four or five by five at correct height or dim level

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants like cannabis. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.
