The HLG 320 Watt XL QB648 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 600 watt HID equivalent light that that flowers a 2.5 by 5 foot space (two of these cover 5 by 5) with a powerful 4000K white light and 660 nm deep red. For vegging, it covers a 5 by 5 space.

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