LED vs. Fluorescent Lighting for Your Grow Operations

LED lights offer safety and efficiency where fluorescent lights can’t

Your technology should match the modern age. There’s no reason to be using outdated fluorescent lights at your grow facility. At ProGrowTech, we understand the need to increase your harvest and maintain quality without spending tons of money. We say: let the technology do the work for you in the new year. And, if you’re still skeptical, our top two reasons to move forward with LED lights are efficiency and safety.

Energy Efficiency

LED lights have truly revolutionized energy efficient lighting. This option only uses a fraction of the electricity that their fluorescent counterparts consume. Because of this benefit, they are ideal for large facilities that need a lot of light, without the skyrocketing electrical bill. Furthermore, LEDs last around 10 times longer than a traditional fluorescent light. When your grow requires a long daily run—particularly in the vegetative stage—LEDs can offer a smarter and more efficient choice. Although LEDs often have a higher installation cost, these bulbs last longer and use less electricity.

While fluorescent options emit heat and light in all directions, LEDs are directional. This means LEDs are delivering their full benefits in a desired direction—for example, at a plant. Simply, it makes sense to choose LED lights. You’ll save electricity, money and light.

Because of LEDs low energy usage and directional lighting, the payback period for those installation costs is short. You will most likely be making your money back in less than a year.


Did you know that fluorescent bulbs use mercury vapor to transport electrical currents? It’s as scary as it sounds: mercury is a toxic heavy metal that can cause damage to the brain, lungs and other organs. When broken, these lights release this mercury vapor, putting those in the vicinity at risk. Because of this toxicity, used fluorescent bulbs often require special recycling processes. In the end, mercury ends up polluting the environment because of disposed fluorescent bulbs.

LEDs do not use mercury in operation. Rather, LEDs—which stands for light-emitting diode—use a solid-state technology to produce light, unlike the mercury vapor found in fluorescent lights. LEDs utilize an electrical current moving through a microchip, which, in turn, illuminates tiny diodes within the bulb. This technology is much safer and is nontoxic.

The Verdict

These are only a couple reasons that LED lighting outperform other lighting options. Beyond efficiency and safety, LED lights are adjustable to fit your exact needs. For instance, LEDs incorporate spectral tuning, which is particularly important in the early stages of a plant’s growth. Spectral tuning allows the grower to maximize yields, manipulate the plant height, and have an overall healthier adult plant.  Fluorescent lights do not have this capability.  Our Evolve lights—specifically the EV155 and EV360—were designed with the early stage of plant growth in mind. By using LED lights, you’re giving your plants the closest thing to natural light while still maintaining control. They’re perfect for encouraging strong roots.

It is important to take safety and efficiency into consideration when choosing lights for your facility. We recommend spending some time researching all the options, however, we are confident in LED lights’ ability to provide direct, effective light, while still being low-cost and nontoxic. LEDs are the best choice to protect yourself while boosting your harvest.

    LED lights are more energy efficient than fluorescent and can save a significant amount in annual energy cost. This is very beneficial when a great amount of light is needed in order to grow plants indoor. LED lamps have the feature of directional lighting which is very much needed for plants, while it also lasts longer than other types of lamps.

    Thanks a ton to ProGrowTech for sharing such a useful guide. Already I have read your article and gotten valuable information for me because I use fluorescent lights in my leaving room corner and was increased electricity bill then I could not understand that why increased electricity bill. Now I understood that Led grow light best technology for present. I will change all fluorescent lights in next month.

    Well, I will save your site and I will share it with my friends. I hope they will be benefited by this blog topic.

    Nice suggestion. I think we should check this out since it is good for indoor gardens. Can you suggest the best one for budget of $1,000? Thanks.

      How big of a garden is it? I bought a simple desk clip grow light (LED) and it cost maybe $30. I’ve seen some hanging LED grow lights for about $200.

      The blue/red LED lights have worked amazing so far through vegetative stages. Time to see what the flowering stage will be like.

        Hi Dan! Plants need different qualities and quantities of light from propagation through flower. Just like the sun is not stagnant, just like temps and atomospheric conditions are not stagnant. These all have affects on the photosynthesis of the plant. The middle part of the spectrum matters, too! Feel free to call us for more info.

        How many watts is your lamp? I’m struggling with my small LED grow light stuff and feel dispondent that I wasted seed…

          Hi Nev,

          Our flowering fixtures come in both 700W and 580W configurations. Both at 2.5 µmol/j.
