Horticulture Lighting Group HLG 350R
Get the most light for your buck and increase your bottom line by switching to HLG LED Grow Lights. Designed to replace a 600W HPS in veg/flower with as little as 330W, these lights are ideal for commercial growers trying to get more efficiency out of every inch of their grow room or closet-sized home growers looking at making the jump to LED.
Each HLG 650R uses 2 of HLG's custom designed full-spectrum high-efficiency Diablo (QB648) quantum boards with Samsung LM301H white and LM351H deep red LED diodes. They deliver 3.11 PPF per watt.
HLG 350R Quantum LED Grow Light Features
- QB648 quantum boards: high-efficiency and custom-designed Diablo boards deliver 3.11 umol/j (this is why you get 600w HID equivalent light while using only 350w)

- Large coverage: 3 by 5 foot coverage for flowering; 5 by 5 for vegging
