Have a look at our Q2 presentation video. We'll show you what's inside the box,
how to assemble and hang the lamp as well as some practical uses.

  • Grows Any And All Plants: The LEDTonic Q2 LED grow light is versatile and will work with all plants. It covers a 1.5x1.5' area with high-light intensity (tomato, pepper, cannabis plants) and 2x2' area with medium-light intensity (herbs, microgreens, house plants).
  • Small, Neat, Efficient: Fits all spaces; from your window sill to garage shelf to grow tent. Comes with a 6' power cord which connects to the lamp's E27 base. Hang the lamp from above or from its side; whichever way gives your plants the best light coverage.
  • Incredibly Cost-Effective: At 36W draw power, the Q2's cost comes out to $1.52/watt for 1-pack, $1.24/watt for 2-pack. Plenty of bang for your buck, which both your plants and wallet will love!
  • Premium Samsung Diodes: The LM561C model is among the highest performing, longest-lasting, and most efficient diodes on the market. Cleverly built with low operational temperature will ensure the lamp lasts 50.000++ hours (5.7++ years of CONSTANT use).
  • Choose The Right CCT For You: The Q2 comes in 3500K (white), 4000K (blue) white-light spectrum. 3500K generally works best for most plants but the Q2 allows you to experiment with different CCTs to please your curiosity.

LEDTonic Q2 Indoor LED Grow Light

We set out on a quest to create an indoor grow light that is both high-performing, discrete, and easy to use. We challenged ourselves to design a lamp that you can be proud of showing in your home as a part of your interior design while still making it powerful enough to satisfy high-light plants. In contrary to many other lamps on the market, the Q2 will emit a neutral white, sun-like, light that is easy on the eyes and effective on your plants. The Q2 was engineered to need no fan while still maintain a cool temperature for maximum longevity.

The Q2 comes in three different CCTs ("shades" of white light): 3000K with a red lamp holder, 3500K with a white lamp holder, and 4000K with a blue lamp holder. 3500K is the most common and generally preferred spectrum but we know that growers like to experiment with all possible factors and we want to support this curiosity.
