Best LED Grow Lights Under $300

1. Advanced Platinum Series P150 LED Grow Light

Best Led Grow Lights

The P150 offers the full 12-band light spectrum from ultraviolet to the upper infrared. This is truly about as close to sunlight as you can get with indoor LED lighting.

The LED lamps within the P150 ensures that the intensity of the light emitted remains constant.

Coverage wise, the P150 offers a maximum of 4.5ft by 3.5ft area coverage when suspended at 18 inches above the growing area. Its core coverage is 3ft by 1.5ft.

This means that the P150 is able to cover up to 4.5ft by 3.5ft during the sprouting stage of your plants and 3ft by 1.5ft during the flowering or blooming stage where the plants need more intense light, which reduces the coverage area.

[alert type=”info” icon-size=”hide-icon”] With its integrated 90-degree secondary focusing lenses, the P150 is able to provide deep light penetration to focus the light on the covered area.[/alert]

Another cool feature of the P150 is its selectable veg/flower switches to ensure that your plants get the appropriate type of lighting for the particular growth stage that they are in.

At a price range under $300, this LED grow light certainly doesn’t come cheap. What makes up for the relatively high upfront cost is its great energy efficiency.

Unlike conventional white LEDs and High-Intensity Discharge (HID) lights, the P150 LED grow light uses less than half the electricity and heat to produce the same growing power. Its photosynthetic active radiation (PAR) per watt is much higher.

In fact, the P150 can provide the same light intensity as a 250-watt High-Pressure Sodium (HPS) lamp and only use 86 watts.

This is thanks to Advanced Premium Series’ proprietary, auto-switching 110-volts/220-volts LED drivers which provide maximum output with as little input as possible, with the flexibility to adapt to any global voltage output.

To top it all off, the P150 also comes with a five-year warranty as well as a 90-day money-back guarantee.

We like that the P150 offers great versatility for worldwide use, full light spectrum with veg/flower switches, and one of the more well-covered warranties.

For the Best LED Grow lights under $300 category, the P150 is certainly amongst the best LED grow lights. 2020 reviews of this product have been mostly positive, a reflection of Advanced Premium Series’ consistency and reliability when it comes to its LED grow lights.

3. Galaxyhydro 300W LED Grow Light

Galaxyhydro 300W LED Grow Light

The Galaxyhydro 300W LED grow light is the most inexpensive LED grow lights that we have reviewed under $300 category.

Of course, with a lower price tag, you’re bound to expect some differences compared to other LED grow lights in the same price category.

Starting off with the spectrum of light, the Galaxyhydro 300W LED grow light offers a nine-band light spectrum, fewer than the light bands offered under P150, but sufficient for the optimized growth of most plants, vegetables, and flowers.

Its nine-band light spectrum includes a seven to one ratio of red to blue LEDs, plus ultraviolet and infrared.

In terms of the coverage, this LED grow light is ideal for a 2ft by 2ft grow space with a ceiling height of 18 to 25 inches and it is intended to be daisy-chained.

This means that you should probably get two to three of this LED grow light and link them up like Christmas lights so that you can cover a larger grow space.

Would this count among one of the best LED grow lights? 2020 reviews seem to indicate that this would depend on your purpose of use.

According to an updated review, the Galaxyhydro 300W LED grow light works amazingly well for the flowering stage but pales in comparison when it comes to the vegetating stage.

The user suspects that it might be due to the lack of blue light from the Galaxyhydro 300W LED grow light and this can be supplemented by installing other lights that emit more blue light.

That said, this LED grows light is currently available at a great price. It also comes with a two-year warranty and a thirty-day money-back guarantee.

It may be worth your while to consider this deal for a decent LED grows light that is relatively affordable. We wouldn’t say that it tops the under $300 category, but it’s definitely the most economical buy!

Best LED Grow Lights Under $500

4. Advanced Platinum Series P300 LED Grow Light

Advanced Platinum Series P300 LED Grow Light

All LED grow lights in the Advanced Premium Series tout the use of innovative full-spectrum technology that will help keep your grow space and the plants cool while fulfilling their light needs. The P300 is no exception.

Like the P150, the P300 boasts of all of the manufacturer’s trademark features: two to three times the light intensity of other competing LED lights, a 12- band light spectrum that mimics sunlight, customizable veg/flower switches, and if we forgot to mention earlier for the P150, its virtually silent and high-speed fans with improved cooling heat sinks.

Now you’re probably wondering about the price premium you are paying for the P300 since it costs at least a third more than the P150.

The difference mainly lies in the P300’s wattage and energy efficiency.

The P300 can replace a traditional 400-watt HPS lamp and for the equivalent energy produced, only consume 180 watts of power. So, you can generate higher light quality and intensity for a lower price.

So instead of getting two P150, you can just use one P300 to provide the level of light quality and intensity that you want for less than double the price of a P150 (which would be the price of two P150 LED grow lights). Higher wattages also mean that the P300 is able to cover a larger grow room.

Like the P150, the P300 comes with a five-year warranty and a 90-day money back guarantee.

If you are comfortable with moving your budget to the under $500 category, the P300 might be a better choice for the best LED grow lights than the P150.

How to Choose the Best Grow Light – Buyer’s Guide

To select the best grow light, you will need to consider a number of factors.

First, how big is the area that you need to cover? Your grow light should be sufficiently powerful to cover the entire area where you grow your plants. Consider the size of your grow room, including the height and footprint of the space.

You will notice that most manufacturers provide a “core coverage” number for the LED grow light, which refers to the grow space area that the light is able to cover. There are some good guidelines on websites like Plantazoid that suggest the ideal type of LED grows light depending on the size of the grow room.

You should also consider how many LED grow lights you will need and how they should be placed to maximize coverage. As a general rule, to increase space coverage, you should place more lights adjacent to each other.

Next, what are you growing? Depending on whether you are growing green crops, bushes, trees, etc., you may want to select particular setups that would be most conducive for the plants that you are growing in your grow room.

All LED grow lights that are full-cycle will be able to grow plants from the seedling stage to the flowering stage.

However, some LED grow lights are specifically designed for certain types of grows. One good example would be LED grow lights that are designed to grow cannabis.

[alert type=”info” icon-size=”hide-icon”]There are also LED grow lights that are designed for the indoor gardener when it comes to growing fruits, vegetables, and even flowers.[/alert]

The type of LED grows light is also important. As you may have realized by now, there are different types of LED grow lights that you can choose from.

Lights that are tailored for growing cannabis and vegetables can have various options in terms of the accompanying features. For example, there are LED grow lights that include single-channel lights (on or off), or two-channel lights that have a vegetable and bloom mode, and lights that can be programmed to set your preferred light schedules and even customize the spectrum and intensity of the lighting.

Programmable LED grows lights are considered one of the best LED grow lights. Reviews will tell you that these are among the advanced versions that make growing your crops close to effortless.

Using LED grow lights because they are supposed to have long useful lives? Well, yes, but that doesn’t mean you should ignore the warranty provided and the reputation of the manufacturer.

Don’t just take the manufacturer’s word for it, read the fine print. Given the large upfront investment that comes with acquiring LED grow lights, you don’t want to end up with the lights breaking down within months and having no recourse because you forgot to check if there was a warranty.

A reliable warranty will help to cover costs of replacing parts and possible repairs down the road, usually, five to six years after you have purchased and used the LED grow lights. Make sure that you get to benefit from the long-term savings that supposedly come along with the best LED grow lights. Reviews will indicate whether the manufacturer is a trustworthy supplier who honors the warranty provided for the product.

Last but not least, your budget is also an important factor when it comes to selecting the best LED to grow light. Obviously, high-quality LED grows lights come at a price. Consider the budget that you are willing to spend, and possibly the potential income you may get from your business if you are growing for profit, and work backward to decide on the best LED grow light that will be value for your money.

Why Choose a Full-Spectrum LED Grow Light?

If you have done some research online, you may be wondering why everyone seems to be touting full-spectrum LED grow lights. There’s some science behind this, but we’re here to break it down so that it’s easier for you to understand some of the reasons why full-spectrum LED grow lights are considered the best LED grow lights.

Ever wondered why many farmers still prefer to plant outdoors where possible? This despite land scarcity, exposure to the elements, etc.? Well, it turns out that sunlight plays a huge part in this. Sunlight offers the whole spectrum of visible light which is important because many plants require different colors of the light spectrum during different growth stages.

If you only use a certain type of LED grow the plant, it’s likely that your plants will not have the appropriate color spectrum for one of the growth stages. Blue LED lights, for instance, maybe great when it comes to encouraging vegetative growth, think plants that grow tall and leafy, but they aren’t so useful if you are at a stage where you want your plant to bud and flower.

In fact, this is where blue LED lights alone may result in not so ideal situations where your plants turn out to be busy with minimal buds that can eventually flower. Red LED lights, on the other hand, are really beneficial for the budding and flowering of plants, but this alone is also not sufficient if you want your plants to eventually grow tall and healthy.

That said, you may think that it will be fine for you to just get red and blue LED lights. Well, that’s not the end of the story. While there are different views on the value of ultraviolet light, there has been some research that suggests that the use of ultraviolet light in short bursts can help to boost THC production, i.e. increase the potency of the growing cannabis.

As for white LED light, it isn’t particularly helpful to the growth of the plants, but in an indirect way, it helps you, the grower, better see and resolve any potential problems in your grow room. These aside, research also suggests that plants are used to growing with the full spectrum range that’s available from sunlight, which is probably why the isolated use of blue and red LED grow lights may still not be an ideal way about it.

Since full-spectrum LED grow lights mimic real sunlight, it is probably best to use them in your grow room to achieve the best possible outcome. This is also why all of our recommended LED grow lights below are full-spectrum LED grow lights or at least LED grow lights that come with some combinations of the different spectrums that are essential for particular crops they are designed for.

LED Grow Lights Q&A

Now before you head out there to buy LED grow lights, this section is worth a read if you don’t have a good understanding of LED grow lights. If so, some of the terms we’ve used to describe the LED grow light features above may not be things that you are familiar with. To clear the air, here are some Q&A that we hope will be helpful for you.

What is an LED Grow Light?

LED stands for light-emitting diode. It is what we call a “solid-state lighting technology”, also known as SSL. In essence, an SSL gives out the light from a piece of solid matter. This is unlike an incandescent bulb that gives out the light from a vacuum or a compact fluorescent light that gives out the light from gas.

LED lights have come a long way from their humble beginning as indicator lights on electronics. Today, they are a popular choice of lighting because of their many favorable qualities: power efficiency, relatively long lifespan (around 50,000 to 100,000 of hours compared to other lights which need to be replaced after about 20,000 hours of use) and lower heat dissipation (they can remain cooler compared to other lights). This is also why LED lights have become a favored choice for grow lights, which are lights used specifically for growing plants, think horticulture and even food production like hydroponics.

An LED grows light is basically an artificial source of light to cultivate plants indoors. It makes up for the lack of sunlight available to the plants indoors by mimicking sunlight or providing the light spectrum needed for the plants to grow. LED grow lights can be used for industrial or household purposes.

How Do LED Grow Lights Work?

As mentioned earlier, LED works by emitting light through a piece of solid matter. LED grow lights work by sending an electric current through a semiconductor material. Doing so excites the electrons and this results in a powerful light being emitted from a relatively small bulb. Depending on the materials used for the semiconductor, you can create LED diodes that emit various wavelengths of light. This allows you to provide your indoor plants with the different light wavelengths that they need for every stage of growth.

What Are the Benefits of Using LED Grow Lights?

There are many benefits to using LED grow lights and we have highlighted the following for your information.

Energy Efficient

Other conventional forms of lighting are sufficiently powerful to serve as grow lights, but the downside is that they are not very energy efficient. HPS grow lights, for instance, require much more power than LED grow lights to run effectively. So, even though HPS grow lights are not as costly as LED grow lights up front, the cost can add up in the long run because of the higher power requirements. The same problem plagues HID grow lights and fluorescent grow lights. This is the reason why LED grow lights are the preferred choice over these other more conventional forms of lighting. In the long run, the energy efficiency of LED grows lights helps you save more money down the road.

Lower Heat Dissipation

The temperature of your grow room or tent can make or break your harvest. Maintaining the optimal temperature of the room or the tent is extremely important to ensure that your plants stay healthy. HPS and HID grow lights produce an incredible amount of heat, which means you have to invest in extensive cooling systems so that you can prevent your room from overheating. With LED grow lights, you don’t have to invest so much money in cooling systems because LED grows lights have the innate advantage of remaining cool or just warm to touch even after long hours of usage.

Longer Lifespan

Generally, LED grow lights can last for 50,000 to 100,000 hours of use. Of course, there are a few rotten apples here and there, but broadly speaking, if you use the best LED grow lights, it is highly likely that you won’t have to replace your lighting system for years or even a few decades. In contrast, other grow light options such as the HPS grow lights and fluorescent grow lights will need to be replaced much more frequently.

Saves Space

A relatively small LED grow lamp can emit a large amount of light. Because it doesn’t require as much equipment to run these LED grow lamps, you can free up a lot of space in your grow room or your grow tent without having to worry about the additional equipment or cooling systems that will inevitably take up space that could have been put to better use, like more space to put your plants or areas to access your plants.

More Environmentally-Friendly

LED grow lights are more energy-efficient, which also means that they are more environmentally-friendly. HPS grow lights, on the other hand, are less energy-efficient and linked to a large amount of carbon dioxide emissions in today’s world. Fluorescent grow lights are also not the most environmentally-friendly alternative. Because they use mercury vapor and other inert gases pressurized inside the tube, they become a hazard when they need to be disposed of.

How Many Watts Do You Need?

On average, an LED grows light needs about 32 watts of power to cover 1 square ft of flowering plants. For vegetating plants, you will need much less wattage, about 50% less because plants in the vegetating stage do not require as much light intensity.

As a general rule, you should consider the number of plants that you intend to grow in your grow room, the area that will be covered by your plants in the grow room, and the recommended LED wattage for the number of plants grown in the space. Obviously, the more plants grown, and the larger the area occupied by your plants in the grow room, the higher the wattage required to ensure sufficient light intensity provided to all the plants. Depending on the make of the LED grow light, it is best to look at the manufacturer’s recommendations when it comes to the number of watts you need to optimize the growth and yield of your plants.


With all this information, you are all set to buy the best LED grow lights for your needs! Now that you have a better idea of the recommended brands and models, benefits of LED grow lights and the wattage requirements, it’s time for you to get cracking!
