The TaoTronics Full Spectrum LED Grow Light Bulb provide everything your plant needs – on the light side of things anyway – with a selection of 12 evenly spaced LED bulbs you get all of the wavelengths that encourage your plant to grow in a single bulb.

You’ll never need to worry about heat with this grow light. On top of being an already low output LED, it features an aircraft grade heat sink with aluminum fins which dissipate the heat 1.5 times better than its predecessors. Even after 24 hours of continuous use this lamp will be cool to the touch, which makes it super safe for your plants.

Now unlike the other options on this list, instead of being a full-fledged lamp, this is just a bulb. That means that it’s super easy to install and doesn’t require the sort of extra set up a lamp might require. It’s designed to be compatible with standard E26 / E27 sockets and 100-240 AC, so you should be able to use it pretty much anywhere and it comes along with a free E26 socket to make things even easier.

Since it’s just a bulb, you’ll find that it has a smaller illumination area than some of the lamps. However, with a 60-degree beam angle you’ll still be impressed by how respectable it is. One of the bonuses with this is that if you’re looking to increase the lit area, you can easily (and super affordably) pick up a couple more bulbs.

ColoFocus 1000W LED Grow Light

No products found.

The ColoFocus 1000W LED Grow Light is the most powerful light on this list. If you have a larger space to illuminate, it’s definitely worth taking a look at.

Each individual light features two 5 watt light chips, amounting to an output of 10 watts each with a separate resistance so they work separately and a single bulb failing won’t take the entire light out of commission. Combining red and blue lights with a handful of infrared and UV lights as well, this grow light is designed to seriously support your plant’s natural growth and encourage higher yields and healthier plants.

Since this grow light uses LEDs, heat output isn’t something you have to worry about too much. Just to be sure though, this unit includes an effective pair of built in fans that run whenever the lights are on. They’re strong enough to promote airflow and keep condensation at bay while gentle enough to help your plants grow strong without knocking them down.

It’s a bigger grow light than the rest on this list and can comfortably light an area of about 3.5 x 4 feet, though the exact number will vary by the height you place it at. It’s not waterproof, so you’ll want to make sure to use this product indoors and somewhere it’s unlikely to get splashed.

Things We Like

Types of Grow Lights

Most of the grow lights on the market for smaller scale growing are one of two kinds: fluorescent or LED.

Fluorescent Grow Lights

Fluorescent lights have been around longer and they certainly have their advantages. They create light by running a current through mercury vapor, starting off a chemical process to produce the light we see. They’re available in a whole range of different sizes, wattages, and outputs and they’re easy to use, requiring no special set up beyond hanging the lamp.

Fluorescent lamps are great at encouraging growth in the early stages of a plant’s life, but aren’t as good at supporting your plants through the flowering stage. You’ll rarely need to worry about the temperature of your lamps causing trouble for your plants, but it does need to be considered if you’re using high-output fluorescents.

While they’re often a bit cheaper upfront, fluorescent lights cost more to run in the long term and have a much shorter lifespan overall. You’ll need to be careful with your fluorescent lights as well. Since they contain mercury, which is highly toxic, breaking them can cause health issues and they continue to pollute the environment long after you dispose of them.

LED Grow Lights

Unlike fluorescent lights, LED lighting gives you a lot more control over your growing, by allowing you to customize your light spectrums during different stages of a plant’s growth. Instead of operating on the wavelengths available, with LED lights you can have different light chips operating on different wavelengths, which means you can get a perfectly tailored ratio of red to blue light, with a few other wavelengths thrown in for good measure.

They’re also incredibly efficient, using a fraction of the energy of other lighting types and lasting up to ten times longer. Since they’re directional, unlike fluorescent lights which transmit light and heat in all directions, where your LED is pointed is where the light will go, so you’re not wasting energy lighting the ceiling and instead all of the light is directed at your plants.

They’re also non-toxic! No mercury vapor floating around inside. You don’t have to worry about a breakage causing lasting problems or contemplate the ultimate effect of your choices as the fluorescent lights continue to leak toxins long after they’ve been disposed of. Instead, you get an effective, customizable light that is energy efficient and completely non-toxic.

 

How to Garden Under Grow Lights

Color

A lot of effort has gone into understanding what wavelengths of light is best for encouraging optimal plant growth, and we mean a lot. To break it down a little, wavelengths determine the color we see light as. When the sun shines, it contains all the different wavelengths of light in itself. If you’ve been outside before, you can see that the sun seems to be doing a great job of encouraging plants to grow.

Since we know so much about how to influence the growth of plants with wavelengths, when we use grow lights we can hack that system to improve yields, taste, and quality of the plants we’re growing. The colors that are most important to plant growth are red and blue.

Blue light helps stimulate the production of chlorophyll, which, as you probably learned in middle school, is the chemical that plants use to create energy from light and gives them their green color. So using blue light helps your plants to be healthier and leafier.

When used in tandem with blue lighting, red lighting also helps your plants to be more productive. Red lighting also encourages your plants to germinate and flower more quickly, increasing their yields. Any LED grow light will have a proper balance between red and blue lighting and you’ll see a marked difference in your plants as they grow!

Intensity/Distance

Each plant has different needs related to how intense the light they’re receiving can be. Plants native to forests or jungles, where they would have lived much of their lives in a shaded environment tend to need less intense light than a native desert plant, which would have been accustomed to intense and undisturbed sunlight.

Since all of your plants will have different needs, it helps to read up on the type of plant you’re growing. You’ll also find that different types of grow lights have different heat and intensity outputs that will affect your plant growth as well. If your plants are too near your lights you could end up with bleached plants, nutrient deficient plants, or, worse, dead plants.

While there are lots of variables to consider as you’re setting up your grow light, here’s a great website with charts you can work off of!

Duration

Since you’re saving so much on power by using LED lights, you may be tempted to leave them on all day long. Some plants will love this, but other plants desperately need the dark to bloom. Some plants, like orchids and cacti will thrive in 24/7 light and grow much faster than they do in the wild. Other plants, like poinsettias, which bloom in the winter and are evolved to be used to shortened periods of daylight, would suffer in a 24/7 situation. In fact, it’s actually the dark that triggers your plants to flower, rather than daylight. There are three main categories of plants based on their daylight and darkness needs.

Short Day Plants

Short day plants would more accurately be called long night plants, because what they need to flower isn’t a short exposure to sun, but a longer exposure to dark. They won’t flower without that uninterrupted stretch of night. This means that if you’re keeping your lights on all day long, you’re going to find that these plants aren’t doing as well as you may expect. With more than 12 hours of sunlight a day, they simply won’t flower. Plants in this category tend to bloom in the spring, fall, and winter.

Long Day Plants

Long day plants require only a short night to bloom. Giving these plants more than 12 hours a day of light will thrill them! Most vegetables, like spinach and potatoes, and summer flowers, like asters and poppies, will thrive under these lighting conditions.

Day Neutral Plants

Day neutral plants will flower regardless of whether or not they’re receiving long days or long nights. Tomatoes and corn fall under this category.

FAQ

Q: Will grow lights burn my plants?

A: Although most of the grow lights on this list are designed with LEDs, so they don’t run especially hot, you certainly can burn or bleach your plants if you don’t use them correctly. The best way to avoid burning your plants is to make sure that you don’t put your grow lights too close to them. Your users’ manual should have information about the proper heights for your specific light and if you can’t find them there, it’s worth contacting the manufacturer to make sure your plants stay healthy and unburnt.

Q: Can grow lights damage your eyes?

A: Depending on the brightness of your lights and the length of your exposure, it is possible to damage your eyes. If you only have a small grow light and you don’t spend an excessive amount of time gardening beneath it, you shouldn’t have any problems. If you’re doing a larger scale project and do spend a lot of time under your lights, it’s not a bad idea to invest in a pair of specially designed LED glasses to protect your eyes from the light that glow lights emit. You can read more information about it here!

Q: Why are grow lights purple?

A: Grow lights are optimized to provide light on wavelengths that plants can easily absorb. The lights they absorb the most tend to be around the blue and red bands of the spectrum. So when you’re buying lights that are designed specifically to help plants grow, they focus on the wavelengths that most plants absorb more easily, thus encouraging a higher level of growth.
