Dimmable LED Grow Lights (The Best Fixtures Reviewed And Compared)

The adoption of dimmable LED grow light for new installations is rising fast, but with a vast retrofit market to address, there is an opportunity for further growth if the user experience can be optimised. LED lighting has already captured the imagination of consumers in a way that CFLs never did with LED lamps offering many of the energy-saving benefits of compact fluorescents but in a much more familiar package.

Dimmable LED Plant Lights: Comparison Table

Spider Farmer SF1000 Grow Light



Spider Farmer is the only one of these brands that combines warm white, cool white, deep red and IR diodes in one fixture.

Specifically, they use 3000K and 5000K white light, red light with a wavelength of 660 nm and infrared light with a wavelength of 760 nm. This spectrum has been shown to give bigger and higher quality yields than one containing only white light.

VIPARSPECTRA PAR700 Dimmable LED Grow Light



Viparspectra’s coverage is significantly higher when compared to that achieved by other brands of grow lights. To illustrate this, thePAR700 Dimmable light from Viparspectra can easily cover a 24-inch high and 5 by 4-foot area.

Viparspectra offers different products with different power consumption levels. For instance, you may wish to replace a 600W HPS with the Viparspectra PAR700 which draws 326W to save on energy costs.

Eco Farm 800W CREE COB LED Grow Light



One of the lowest priced option of the bunch and great energy savings.

These lights deliver 12 bands including 2 IR and 2 UV through optical lens to maximize the PAR per watt. The ECO Farm grow lights are great for the veg cycle and you should see results quickly with the brightness of the light. The lights themselves are very powerful, but don’t give off the same kind of heat as some of the other more expensive brands/lights on this list.
