HLG 350 Diablo - 330W Full Spectrum LED

The HLG 350 Diablo is a high-efficiency, low-profile LED fixture designed to replace a traditional 600W HID using just 330 watts. Powered by two Diablo Quantum Boards® featuring Samsung full-spectrum white and deep red LEDs, this lamp delivers 1000+ PPF at a remarkable 3.11 µmol/Jsystem efficacy.

With its rectangular 35" wide footprint, integrated reflectors, and diffused light output, the HLG 350 Diablo offers excellent canopy penetration and uniform light distribution—making it ideal for compact flowering spaces, grow tents, or veg zones in commercial facilities.
