If you know a thing or two about LED grow lights, you’ve probably heard of VIPARSPECTRA and KingLED. Both are respected brands in the LED grow light industry and make lights that range from basic to complex. Both companies are based in China and sell their grow lights all over the world, especially on e-commerce sites.

Since the grow light you choose makes all the difference when it comes to plant growth, health, and yield, we’re comparing two grow lights in three different categories to point out the best. All six lights have a full spectrum and can grow plants from germination to maturity.

VIPARSPECTRA Reflector-Series 900W VS King Plus 1000w

The first lights we’re comparing to each other are VIPARSPECTRA’s 900W LEDGrow Light and KingLED’s 1000W Grow Light. Our favorite between the two is the VIPARSPECTRA light because of its low price for each wattit draws ($0.59). While its power output isn’t as high as that of the King Plus light, it has a better coverage (4’ x 4’ at 32”).
