The 260-watt V2 quantum board LED is our best selling Quantum board led grow light. It emits light equivalent to a 500 watt HID grow light, making it an energy-efficient replacement to HID lights. With the HLG 260 Watt QB288 V2 R-Spec LED grow light, get 40% higher, superior-quality yields with the 301B LED allows better canopy penetration.

  • Deep Canopy Light Penetration: The 2x QB288 Boards powered by Samsung with 301B LED deeply penetrates canopies and results in 40% higher yields compared to the other models.

  • Dimmable Lights:The Meanwell HLG-240H LED Driver enables you to adjust the light intensity between 135-280 Watts, according to your requirements.

  • High-Energy Efficiency: The 260W QB V2 RSpec led grow lights use 32 OSRAM deep red diodes that promote photosynthesis for the healthy growth of your plant.

  • Noiseless, Passive-Cooled Design: The unit features one slate2 double predrilled 600mm Heatsink allows effective heat management by dissipating excessive heat.

  • Wide Coverage: Designed to flower up to a 2 x 4 area or 3x3 area and veg an area of 3x6 ft. or 4x4 ft.

  • Multiple Spectrum for Better Results: 3000K: ideal for vegetative growth, 4000k: ideal for seed to harvest full spectrum, All new RSpec spectrum for full spectrum growth with an added red spectrum enhanced flowering.

The quantum board, powdered by the Samsung LM301B diodes, helps achieve the highest output per watt of any LED grow light on the market. It promotes better canopy light penetration so that you get 40% better produce than that with previous models. The top bin diodes by Samsung consume minimum energy in comparison to other growl ights in it's class. That’s why the HLG 260 watt V2 saves you on electrical costs.

The HLG 260 watt QB288 LED kit features the OSRAM 660nm deep red diodes available in the market for growing indoor plants. The wavelength of the 600 nm hyper or deep red diodes promotes the process of photosynthesis which helps in growing dense and healthier plants.

A dimmable driver lets you adjust the light emission. So, you can easily adjust the heat and light according to the growing space and the requirements of your plants.

The 6FT Nema 5-15P 16/3 SJTW NA Power Cord is an extension cord perfect for indoor and outdoor use. It provides 6ft. additional length to the board from the power source. You can plug the cord to the NEMA wall or equivalent for standard 120VAC with a cable connector.
