Grow Lights – a grow light does exactly what it says on the tin so to speak, it is a light designed to literally help your plants grow. Sometimes referred to as grow lamps, grow bulbs or grow kits; these were originally designed to enhance the growth of herbal plants.

Today, however, these lights are becoming increasingly popular and are more in demand than ever. The reason for this is due to an ever increasing world wide population, ever eroding coastlines, both meaning there are more and more people per square kilometer and not enough houses with gardens or outdoor spaces to grow plants or vegetables. This has resulted in people trying to grow food and many other types of plants within their own four walls, which in turn has caused a huge demand for equipment to do so. With grow kits becoming ever more sophisticated and readily available over the years, particularly online; and prices dropping drastically over the past 10-15 years, there has been a sudden surge in the everyday populous purchasing these items, and, they are eager to know about all that’s available including the latest technology and double ended grow lights.

This article digs deep into the best double ended grow lights in the market. Keep reading!

What is a Double Ended Grow Light?

Double Ended Lights, or, sometimes referred to as Lamps, are HID or High Intensity Discharge lights (High Pressure Sodium, Metal Halide, and Ceramic Metal Halide) that operate at ultra high frequencies, thus, the temperature and operating current are well balanced and much more constant. 

Having two connection points, one at each end, as opposed to the one connection point on a Single Ended (SE) bulb, the filament inside gets intensely hot compared to the latter, hence an extremely bright light is emitted – much stronger than from a Single Ended lamp. Some say even as much as 10-20% brighter. The main problem now is there is so much choice, how do you know which one to go for?

Good Or Bad – Why Buy Or Use Double Enders?

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 D.E. 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 S.E. 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.

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.
  • D.E. 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.

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.


The market is ever expanding and the products are ever evolving to meet demands and expectations of customers, and keep up with their competitors. The internet has given the customer a mammoth selection of options to meet their individual requirements. Somewhere amongst all these items, about ten or so years ago, along came the best double ended Grow Lights – are they good,  are they bad, are they value for money? 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 D.E. 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: Best product 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.
