While all of these lights are awesome and are loved by indoor growers, there is one that stands out from the rest, the Roleadro Galaxyhydro 300W Grow Light. Why is it our top choice? Well, there are a few reasons. For starters, unlike some of the other lights listed here, it has UV and IR lights, which help plants to develop well. Secondly, it has a good coverage. Thirdly, it is designed in such a way that almost all the light it emits is absorbed by plants. The most affordable light on this list is clearly the Roleadro 45W LED Grow Light, but it only emits 25 watts per hour and is only ideal for microgreens and seedlings. It is not recommended for the blooming or fruiting phases.
