The HLG 260 Watt XL V2 RSpec DIY LED Grow Light Kit from Horticulture Lighting Group is a great way to get a high-quality American-made light for less. You simply have to assemble the components yourself, but it is surprisingly easy (see the video below).

Once assembled, you get a 500 watt HID equivalent light that that flowers a 2 by 4 foot space (two of these cover 4 by 4) with a powerful 3500K all-white light with supplemental 660 nm deep red diodes. For vegging, it covers a 4 by 4 space.

NOTE: This kit is shipped disassembled and requires assembly before use.

 

HLG 260 Watt XL V2 RSpec DIY Kit Features

  • Ideal spectrum: 3500K white light plus 660 nm deep red
  • Great coverage: 2 by 4 foot coverage for flowering; 4 by 4 for vegging
  • Top-bin Samsung LEDs: high quality LM301H 3500K + 660 nm Deep Red diodes are super efficient and long-lasting
  • Dimmable driver: Meanwell XLG-240 driver is dimmable between 135 and 280w
  • Wider spread: 3 foot long heatsink gives you a wider light spread
  • American-made: designed and manufactured in the United States
  • 1-year warranty

 

HLG 260w XL V2 RSpec DIY Package Includes

  • 2x QB288 V2 R-Spec Quantum Boards
  • 1x Slate 2 Double Predrilled 891mm Heatsink
  • Meanwell XLG-240-M-AB LED Driver. 93.5% Driver Efficiency. Boards should be wired in series with the driver for maximum output
  • 6FT Nema 5-15P 16/3 SJTW NA Power Cord or equivalent for standard 120VAC with cable connector
  • 2ft solid core Wire, 2x Wago Connectors for DC wiring

The Horticulture Lighting Group 260 watt XL V2 Rspec DIY kit is an opportunity to get an American-made LED grow light with extremely high quality components for the price of a much cheaper Chinese brand. The only catch is that you have to assemble it yourself.
