Accepting Preorders - Shipping June 17th.

NEW - Rspec Quantum Board for Enhanced Flowering and General Use!

A Preinstalled External Dimmer Knob Now Comes Standard with All 600H Kits (Ready to Assemble and Preassembled) Without the Bluetooth Option

This DIY kit will easily replace any 1000 Watt HID using only 620 Watts of power producing a massive 1540 PPF total output! To put this in perspective, a single ended 1000 watt produces around 1250 PPF total. The HLG-600H produces 20% more light than the SE1000 watt with 40% less power! The 600H uses 4 ultra high efficiency V2 Rspec Quantum Boards driven by a Mean Well HLG-600H-54B LED Driver and is available as a preassembled and tested kit (recommended) or a ready to assemble DIY kit.

The new R-Spec spectrum will enhance flowering while still being a great all-around light from seed to harvest. The excellent performing QB-288 V2's in 3000k and 4000k are also available.

An optional Bluetooth controller is available for wireless scheduling and dimming via iOS or Android app. Full-color basic wiring diagrams are included with all ready to assemble 600H DIY kits.

The HLG 600H Rspec Quantum Board kit with 1088 Highest Bin Samsung LM301B LED's and 64 Osram deep red diodes is the most efficient grow light kit on the market. Enjoy lower energy cost, less heat, and more output. A 4% efficiency gain over the previous model!
