Best Double Ended (DE) HPS Grow Lights of 2023

What is a double ended (DE) HPS grow light? Double ended grow lights, sometimes referred to as grow lamps, are High Intensity Discharge (HID) grow lights that operate at ultra high frequencies.

They’re one of the two main types of grow lights used to grow cannabis.

These lights utilize High Pressure Sodium (HPS), Metal Halide (MH), or Ceramic Metal Halide (CMH). While quite effective, these grow lights are no longer the most efficient on the market.

You can purchase a LED grow light that uses a fraction of the energy of HPS, MH, or CMH double ended grow lights. The only downside is LED grow lights are a little more pricey. You can start reading about them here.

Despite double ended (DE) grow lights being less efficient, they still hold a piece of the grow light market, and so I’ve researched the best models for you in this article.

Double Ended vs. Single Ended Grow Lights – What’s The Difference?

  • Double Ended bulbs boast two connection points, one at either end, whereas a Single Ended bulb or lamp, only has one connection point.
  • Double Ended lights get much hotter, producing far more light and heat than a Normal or S.E. one, which in turn, gives maximum yield and greater profits if selling your bud.
  • Double ended grow lights require a much bigger financial layout than Single Ended to begin with, but, are more cost effective in the long run.
  • Double Ended are also less likely to be available second hand.

Double ended (DE) grow lights have the positive and neutral sockets at each end of the fixture, as opposed to the one socket on a Single Ended (SE) bulb. The extra socket equates to extra brightness, and therefore efficacy.

This TopoGrow double ended HPS kit includes a 2100K spectrum bulb, reflector, ballast, hangers and hooks.

While the spectrum of most HPS grow lights can’t compete with LEDs, these type of grow lights are better for growing in large areas of 5×5 feet and above. That size grow space can be considerably more expensive to light properly with LEDs.

The hood reflector is designed with heat dissipation and light reflectivity in mind.

Vivosun says this light will produce a considerably amount of heat, as is expected with a 1000 watt high intensity light fixture. If you’re using the proper ventilation and HVAC you’ll be fine.

This system has a overheating and short circuit protection feature, so you can sleep easy knowing your high powered grow light isn’t a fire risk.

At the heart of this system is Vivosun’s low frequency Square-Wave technology ballast which is high efficiency, reliable and causes no electromagnetic interference.

You can run this grow light on 120 or 240 volt outlets. Since it’s completely silent and lightweight, you won’t be disturbed as this ballast is entirely noise free and can easily be moved.

Good Or Bad – Why Buy Or Use Double Ended Grow Lights?

There are a few benefits to double ended grow lights compared to single ended grow lights.

The light coverage and power consumption of DE grow lights is more efficient than single ended grow lights. Double ended grow lights also provide a substantially higher light intensity than conventional Single Ended or SE lights.

You get a better spread of light and higher lumen output providing up to 50% more usable light while using the same amount of power! And if that’s not impressive enough, even after 10,000 hours of burning, the intensity of double ended bulbs stays at a whopping 90%.

In contrast, double ended grow lights are more expensive. This applies not only to the bulbs but to all parts of the setup. Although the DE lamps do provide a lot of benefits and are more economical in the long run, the cost will be a factor to consider.

As long as you have a method to control heat, which most growers do, then double ended grow lights can still be an attractive growing option.

Difference between HPS and LED grow lights:

HPS Grow Lights vs LED Grow Lights

There are three main differences between HPS or Double Ended grow lights, and LED grow lights.

The first difference is cost. HPS grow lights cost a fraction of good quality LED grow lights, and that’s what keeps them attractive even as LED grow lights have really gained popularity.

The downside to HPS grow lights is they produce much more heat than LED grow lights, and so they aren’t good for small grow tents, or even small areas with no ventilation.

Growing cannabis, fruits or vegetables indoors requires a specific temperature and humidity. HPS light users can definitely face a challenge in maintaining a proper growing environment.

The third difference is the ability to control and produce more favorable light spectrum with LEDs compared to double ended grow lights like HPS or MH grow lights.

It’s Not Just About Lights – What About Reflectors, Connectors, Ballasts & Bulbs?

Complete kits like the ones highlighted above are the best option so you can be sure it’ll all work together.

If however you decide to buy individual pieces, make sure you double check all the specifications. Otherwise you could end up with a ballast that cannot be controlled by any connector or a double ended bulb and a single ended reflector!

Final Thoughts:

The grow light market is ever expanding and the products are ever evolving to meet demands and expectations of customers. The internet has given the customer a mammoth selection of double ended grow light options to meet their individual requirements.

LED grow lights have just about replaced DE grow lights at this point, but HID grow lights can still be used.

If you have a flexible budget, you may want to buy a DE Grow Light setup – it should pay off in the long term though with increased yield.

Best Product From The Reviews: The best double ended grow light really depends on individual requirements and funds available. For a commercial setup, the Yield Lab Grow Kit is one of the best choices, but ultimately it’s up to you!


Are HPS or LED grow lights better?

LED grow light technology has surpassed HPS grow lights in terms of light spectrum and power consumption. LEDs can also provide more uniform light coverage.

Are double ended grow lights still worthwhile compared to LED grow lights?

Double ended grow lights will still grow plants well, as long as your grow environment can handle the heat they emit.

What’s the difference between Double Ended (DE) and Single Ended Grow Lights?

Double Ended grow lights have an extra light socket, produce more intense light, and emit more heat. Double Ended grow lights are typically priced higher than single ended grow lights.

What’s the best type of DE grow light to purchase?

It’s best to purchase a double ended grow light kit to ensure all the parts are compatible with each other.
