Best Double Ended (DE) Grow Lights – Everything You Need To Know

What is a double ended (DE) 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. Thus, the temperature and operating current are well balanced and much more constant.

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 (Normal) 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.

Difference between HPS and 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.

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

Whilst light coverage and electrical use, may be far more efficient,  than single ended lamps economically speaking; and some would they are comparatively maintenance free when up against the average single-ended light, upon initial purchase, they are also more costly. This applies, not only to the bulbs, but, to all parts of the entire setup. This may be fine for the more established grower, however, a newbie starting out, would most likely find it difficult to afford such luxury. Although the DE lamps do provide a lot of benefits and are more economical in the long run, they could well be out if reach for many newcomers or even some more established small scale home growers. They do also provide a substantially higher P.A.R. output and light intensity than conventional Single Ended or SE lights.

Benefits of Double Ended Grow Lights

Where can I start – well, this innovative newfangled double ended light technology is groundbreaking! Not only do you get a better spread of light, require less fixtures and fittings, get an higher lumen output, but, you get a more effective use of the lumen output; providing up to 50% more usable output but, only using the same amount of power! What else, I hear you say? According to information from growers and tests from independent sources, for the same expense of running a High Intensity Discharge setup, you can have an much more sizeable footprint plus an increase of 20-50% on your yield – now, that’s quite an achievement! As it kicks out over 2000 micromoles of luminous energy, it is also great for bloom crops. 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%!

Whether you’re a home grower with just a few plants or have a gigantic industrial unit with 1000s of buds, these are the lights for you! Even starting out, you can be guaranteed a better score with a HIgh Pressure Sodium (HPS) Double Ended Light.

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

You need to choose the correct items from the beginning, as if you purchase things that are incompatible, you could find yourself seriously out of pocket. If you are just starting out, it is usually best to try and buy a complete kit as that way you can be sure they will all work together. If, however, you do decide to invest in individual pieces, please make sure you check and double check all the specifications twice over, otherwise, you could end up with e.g. a ballast that cannot be controlled by any connector or a double ended bulb and a single ended reflector! So, particularly if buying second hand equipment, where you usually have no comeback or option of returns or refunds from the seller, remember to do your homework first, ask lots of questions and thoroughly check each item before you hand over your hard earned cash.

Conclusion

The market is ever expanding and the products are ever evolving to meet demands and expectations of customers, and keep up with their competitors.

Well, it really all depends on your perspective and your cash flow of course!

If you can spare a few hundred dollars for one single grow kit, you may want to go ahead and buy a DE Grow Light setup, but, for the small time home grower, it’s a luxury – it should pay off in the long term though with increased yield. If you’re a large scale home grower or somebody doing it on a commercial basis, then a Double Ended Grow Lights setup is a must. Yes, it will involve a costly initial outlay, but, when you get your best maximum yield ever- it will definitely save you lots more time, effort and money.

Best Product From The Reviews: The best double ended grow light really depends on individual requirements and funds available. For a commercial setup, the Phantom Commercial Grow Kit with the U.S.B. Interface would definitely be the best choice, but, for a home grower, it is best they check all the available options thoroughly, make sure they have the finances not just for the kit, but, any accessories or chemicals, etc. and then decide what best suits them.
