LED grow lights intended for large spaces can be expensive. Many grow lights on the market today are either inefficient, don't properly cover the stated coverage area, or are grossly overpriced. When you're spending nearly $1,000 (or more) on a LED grow light, you want to make sure that you're getting not only a high-quality product that will last several years, but also a LED grow light that is efficient and evenly covers the grow space with light.
In this article, I will reveal my picks for the Best LED Grow Lights in 2023. This list will include LED grow lights that have a flowering coverage area of 5'x5' and are best for a full-cycle grow (from seedling through flowering). These are complete fixtures only. This list does not include DIY grow lights or lights that require significant assembly. The grow lights are listed in no specific order. For a LED grow light to make this list, I factor in: PAR output, efficiency, spectrum, light spread, diodes, drivers, and warranty. I've excluded grow lights that are over $1,000 because in my opinion it's simply not worth it to spend more than that to cover a 5'x5' area. Since prices are always changing, click either the Amazon link, Happy Hydro link, or LED Grow Lights Depot link under each light for the most up-to-date price.

Franklin F7000 LED Grow Light
According to Franklin, this F7000 model punches above its weight class thanks to a unique Blood Orange spectrum from a combination of 3000K, 5000K, 660nm, and 730nm diodes. This enhanced red spectrum is ideal for a full cycle grow.
The Franklin F70000 LED grow light produces 946 µmol/m²/s PPFD from a height of 18", and you can expect a PPF of 1975 μmol/s. With eight light bars, your plants will soak up a consistency from corner to corner in a 5' x 5' grow tent.
Helpfully, you also have options for driver placement. Thanks to the 10-foot connection, it's possible to connect directly to the light fixture or remove it from the grow room for better heat management. In addition, it's dimmable yet still scalable to a system with up-to 50 grow lights daisy-chained together.
