Any seasoned grower knows that the more light your plants receive, the bigger the harvest will be. This is due to the fact that light intensity drives plant growth during the flowering stage. That’s where double-ended grow lights come in.

There’s a reason commercial growers have been using double-ended (DE) grow lights for years. Now, though, this type of grow light is highly popular among home growers, too.

Selecting the perfect double-ended grow light kit for your grow room or grow tent can be a difficult task. Where do you start? Well, a bit of research is a great jumping off point, and that’s why we’re here. We’ve compiled a list of the top double-ended grow lights so you can narrow down your selection to the very best.

Before we look at the best kits, though, let’s talk a little bit about what makes a double-ended grow light such a great choice for indoor growers.

What Is a Double-Ended Grow Light?

Double-ended grow bulb.Unlike a traditional screw bulb, a double-ended grow light bulb has thin wires on each side — these are fastened into the grow light fixture. In addition, double-ended bulbs have a shorter, thinner arc tube compared to single-ended bulbs.

These installation and design differences actually give DE grow lights a bit of an edge over their single-ended counterparts.

The Advantages of Double-Ended Grow Lights vs. Single-Ended Grow Lights

While both traditional and DE grow lights are great options for anyone with a grow room setup or grow tent, there are some notable perks to using a double-ended option. Double-ended grow light inside grow tent.

  • More light intensity: Double-ended grow lights are pretty much supercharged HIDs. Because these lights have two connection points instead of one, the filament in the tube gets much hotter. When that filament gets hotter, it gives off a much brighter light than its single-ended counterpart — about 10 percent (or 6,600 lumens) brighter, to be specific.
  • Ultraviolet and infrared light wavelengths: Double-ended grow bulbs emit more UV light than single-ended bulbs — this helps with photosynthesis, aroma, and root production, among other things. DE lights also give off a good amount of IR light, which is great for overall plant growth.
  • Less light degradation: Due to their structural design, as well as their ability to easily produce more light, DE grow lights typically last longer than single-ended lights. That means you’ll be able to use your double-ended HPS and MH grow light bulbs for a long time before you need to swap them out.

The Best Double-Ended Grow Lights of 2020

Now that you know what sets DE grow lights apart from standard single-ended kits, you’re ready to make a decision for your grow room. So with that said, let’s take a look at the top 5 double-ended grow light kits of 2020.
