Here in this post I am reviewing LED grow lights for your grow room to grow healthy weed/marijuana/cannabis (whatever you call it :)). Since it’s a big investment, I’ve hand-picked the best lights in the market. I came up with this table after a lot of research – asked friends, reached out to people online, read up many reviews and then came up with these suggestions below.
You’ll need to consider a few factors to choose the best light for your growing room. The light that you would buy need to be powerful enough to cover the area where you grow your weed at. That might also differ depending on whether you have a separate and dedicated space for seedlings & clones or if your weed fully in one place.
The second factor is if you want an all-purpose light, or if you simply plan to supplement your weed with other lamps used for vegetation and flowering or home gardening.
The good thing about LED lights is that you don’t have to worry about replacing bulbs frequently, having to deal with ballast, or running too hot. You wouldn’t find these issues with LEDs. Such issues used to be with HID HPS lights.
Now, how do we choose the best lights for growing cannabis? Let’s take a close look at the best LED grow lights arranged by the area that they cover. That will help you match and pick a light according to the size of your grow space.
Mentioned below are some of the most important things to consider when choosing to buy an LED grow light:
1. The area you need to cover
As mentioned above at the beginning of my post, you should always keep in mind the area that the light needs to cover for growing your weed. That will help you in determining the number of LED lights that you would be needing and which type of LEDs would provide you the best coverage. You can place more lights adjacent to each other to cover more space.
2. The stages of plant growth
You can go for a full-spectrum LED grow light to assist in all growth phases.
3. Angle of the LED lens
You must also look for the angle of dispersion within the LED bulbs. The greater the angles, the more the coverage, while the lesser angles, the lesser the dispersion and more direct light. You need to select between these two options according to your needs.
4. Your budget
You need to figure out the features that are important to you and the amount of money you are ready to spend. I would say if you can invest better, you can grow better weed. But as always, you need to consider the factors, and you can decide that based on how you plan to grow your plant.
Why should you choose a full-spectrum LED grow light?
Well, the answer is simple. Full spectrum LED grow lights are a comparatively new product in the market. And that’s the reason why many growers are not that familiar with these new lights. While most of the growers might believe that large fluorescent lights are the best grow lights to use for an indoor growing marijuana garden, they simply aren’t. I wouldn’t say that they are bad. They are good, but Full spectrum light systems are better because they imitate sunlight. LEDs are environment-friendly too – plus point!
- They stimulate high yields
- They definitely cost less to run over time
- They don’t heat up. Instead, they run cool and hence don’t need extra fans
- They don’t have the problem of flickering
- They don’t need ballast for supporting
- Their lamps don’t need to be replaced for 50,000 hours or more—that saves you years of hassle and provides a problem-free service.
So, you might want to keep it in your agenda to consider updating an outdated system to a full-spectrum LED panel now.
Aside lights, what are the other items that you need to add to your grow room kit? Here is a list of useful gadgets that will be helpful for your grow room:
- Grow room sunglasses
- Nutrients, fertilizers/manure for cannabis
- A row tent as well
- A full Tool Kit for a grow room owner
- Light Meter
- Thermometer and Hygrometer
Sunglasses: Shades? For growing cannabis? Yes, that’s right. Sunglasses. You wear them outside too, right, to protect your eyes from UV rays. Similarly, you need to protect your eyes from UV rays indoors too when you’re running a full-spectrum LED light and have to look at it often.
Nutrients: Like every other organism, even plants need their nutrients and minerals. The nutrients that you provide them don’t just affect the yield. They also affect the flavour. Therefore, always choose your plants’ nutrients cleverly.
Grow tent: Tents provide you with a better ability to control the climate for your weed. It’s a good idea to get a tent even if you’re already growing in a closet or an enclosed space. A tent can help you protect your cannabis from stray light sources when they are supposed to be kept in the dark. Plus, it keeps humidity and smells under control too.
Light meter: You might think that only advanced growers use them. But that’s not the case. You can use one, too. Then when you’re advanced grower, you’ll already know how to use them. Always better to use such stuff even when you’re just beginning.
Thermometer and hygrometer: You will definitely want to know the ambient conditions inside your grow tent. For you, we have picked the most excellent model in the market that will last for years.
Now coming back to the main point of the article, what are the Best LED Grow Lights for the Money. We sorted our list of LED grow lights based on the results they showed and the features they offer.
Advanced Platinum Series P 900
To keep your grow room/tent and plants cool, all of the Advanced Platinum Series light models from PlatinumLED grow lights use groundbreaking full-spectrum technology. At the same time, they keep meeting your plants’ all light needs. The P900 provide their trademark “2x-3x intensity” lights that offer two to three times the brightness of competing LED grow lights.
The P900 has 12 bands of wavelengths of light which include both infrared (IR) and ultraviolet (UV), the fragments of light you cannot see with the naked eye. This panel, and others like it in the Advanced Platinum lineup, is about as close to sunlight as you can get indoors. This model is useful for every phase of growing cannabis and you’ll love it.
You can keep it less bright for sprouting by turning the “Veg” switch on or increase the intensity of the light by flipping the “Bloom” switch on. The 90-degree angle of the LED focusing lenses are designed to send light down into the canopy of your plants which helps in tremendous growth.
It is also energy efficient. It can replace a 1000-watt HPS light at a full intensity and still use only 515 watts of electricity. The price of electricity in the US is around 12 cents per kilowatt-hour (average) and using a 1000-watt HPS light costs you 12 cents every hour. But using the P900 gives the same or better quality of light and intensity at half the price of a 1000 watt HPS.
The P900, when suspended at 18-inches above the plants in your garden, its core coverage reaches up to 3 by 5 feet. The maximum coverage that it can provide is 4 by 6 feet. These dimensions are critical to keep in mind because at different stages of growth of cannabis, you’ll be adjusting (raising or lowering) the light according to your plants’ requirements. During the stage of sprouting, you can cover up to 4 by 6 feet. But at more vigorous stages like flowering, you’ll cover lesser area because you will need more concentrated light. An adult cannabis usually takes up at least a square foot of space in a 3-gallon flower pot, so the P900 model can flower between 12 to 24 at a time.
This light system is not budget friendly. But the fact that the P1200 LED drivers work anywhere in the world makes it worth it. They accept 110V or 220V input (or correctly, 85V to 260V). PlatinumLED offers one of the better warranties in the market. They come with a 90-day money-back guarantee and 5-year complete warranty.
Advanced Platinum Series P600
Consider the Advanced Platinum Series P600 as the most advanced grow light people have ever used. This grow light could be a heavy investment, but most of the growers will swear by the premium results that these lights give which are worth a hefty price tag. It has a durable build and is easy to set up. If you have enough money to invest in your crops, I suggest you go for it because it’s one of the best LED grow lights to buy for growing your cannabis. The core coverage area that this light offers is about 2 feet by 5 feet, so you can flip the “Bloom” switch on for about 5 to 10 plants, max.
The Advanced Platinum Series combined intense light and powerful fans in such a way that the light is intense enough that you can see it penetrate the plants and the same time doesn’t burn your plants up – an excellent feature. These lights also come with a 5-year warranty and awesome customer service provided by the company directly. Imagine the energy that you can save against an 800W HPS alone, this unit will pay for itself before the warranty runs out.
Advanced Platinum Series P300 – Perfect for small grow tents (3′ by 2′)
The Advanced Platinum Series P300 is a great runner-up to the P600. This is a more affordable LED grow light at around half the price of the P600 and offers quite a number of the same benefits as the P600. For those who love the P600 but don’t have quite that large of a budget or size of a grow tent, they can surely go for this model.
It is perfect for compact grow areas with a coverage of about 4.5 feet by 3.8 feet at an 18-inch height. You can also use these lights along with additional lamps for larger areas. It’s an excellent energy efficient alternative to a traditional light as it uses only 180 watts of power. This light is perfect for small home growers. Just as the P600 represents the higher end of the market, this is still a significant piece of equipment, basically a steal for the astonishing coverage it gives.
This system has a considerably high PAR (photosynthetically active radiation) per lumen output compared to any other LED grow light panel we’ve seen. That means the panel gives out about two to three times the intensity of other grow lights.
The most important thing about this light system is that it has an 11 band spectrum that gives your marijuana (cannabis) plants the nourishment value including those needed from UV (ultraviolet) and IR (infrared). They use 3W LEDs in all their light chips. The best 3-watt panels have an additional lens to focus the light a bit more. This model comes with a primary 60-degree lens and a secondary 90-degree focusing lens to give more intensity for enhancing plat growth.
Another reason for the moderately higher price tag is because the chips in this lamp are also replaceable. This feature allows you to keep that 400-watt output, even when a chip blows. You can just order one chip from the manufacturer and replace it when it arrives. PlatinumLED comes with a 5-year guarantee thereby offering security to their customers.
California Lightworks 440W LED Grow Light (ideally for a 3′ by 3′ grow tent)
California Lightworks 440W LED Grow Light falls under one of the more expensive lights categories in the list. But you definitely get the results you pay for. This grow light model comes in a bright red color – different from subtly-colored light panels from other manufacturers.
This model uses 5W LEDs – 88 of them. Therefore, the light is a bit more intense than those with 3W chips. The optics are all high quality jewel glass focused at an angle of 90 degrees. Plus, it has two 15W UV-B tubes to enhance the growth of plants/cannabis at the flowering stages. The model runs cool and quiet with its built-in fans. Also, it comes with a 3-year warranty.
G8LED 600 Watt MEGA LED Grow Light—named “2016 Best LED Grow Light” by HIGH TIMES Magazine
G8LED 600 Watt MEGA LED Grow Light—named “2016 Best LED Grow Light” by HIGH TIMES Magazine
High Times Magazine named this light a winner last year. The G8LED 600 Watt MEGA LED Grow Light is worth the price you pay for the quality you get. It can cover the complete growth cycle of your cannabis because it offers 8-band wavelength, IR (infrared light) and UV (ultraviolet light). These lights stay cool even if you keep the running for a full day (24 hours). This grow light product comes with a two-year warranty and are serviced entirely by the manufacturer. They also reach out to their customers to ensure proper functioning of the light.
G8LED 450 Watt LED Grow Light
The G8LED 450 Watt LED Grow Light is for all the small to mid-size growers to get the most out of your money. You don’t want to invest all your cash on a single light because you don’t have the budget of the big-time growers. This is where this light model comes in. I agree it’s still a bit expensive, but it’s an awesome choice for one of your first upgrades. This light covers 8 bands of the visible light spectrum and IR (infrared), making it a beneficial model to cover all your plants’ needs. Its big brother, the G8LED 600-Watt was named “Best LED Grow Light” by High Times.
MarsHydro Reflector 410 Watt LED Grow Light
The MarsHydro Reflector is a better choice for small square 4’ by 4’ grow tents than many of the rectangular panels that we’ve reviewed. There was slight singing when the “flower” setting was used. But we could see no such issues with the “veg” setting – one of the advantages of an adjustable spectrum. Those who are considering buying other lights will probably want to use this one as a backup light, but it undoubtedly excels when compared to less expensive options.
VIPARSPECTRA Reflector-Series 300W
If you have a small tent, 2’ by 2’ or 3’ by 3’, the VIPARSPECTRA 300 W can be a right choice for you. It has pleased a lot of customers because it has a good number of features for the cost. The manufacturer even chose this model as a top pick in their “growing light fixtures” category.
Apollo Horticulture GL45LED 135W
We should also include Apollo on our list since they are one of the better manufacturers when it comes to LED grow lights. This small LED grow light makes an excellent option for new small plant growers. It fits in a 2 by 2-foot space and can cover three to four plants and uses only around 90 watts of electricity.
This lamp is lightweight and doesn’t require a ballast. So you can hang this lamp closer to the plants than you can with the others because it runs cool and doesn’t heat up. In fact, this is one of my favorite lamp that I like to use for my marijuana seedlings because it covers four critical wavelengths of the spectrum.
This lamp may look small, but it has an impressive life span of over 50,000 hours which is somewhat unusual for an inexpensively priced lamp. Also, it comes with a 2-year warranty. The light will work with the full cycle of growth including the flowering stage, but you might want to add an additional lamp for that part.
Galaxy Hydro 300W
The Galaxy Hydro 300 Watt panel is a 9-band spectrum light panel with a seven to one ratio of red to blue LEDs and also includes UV and IR. This model is one of the least expensive grow lights that we’re reviewing in this post. It’s It can cover 2′ by 3′ at most. Also, use this light only for sprouting, not flowering. It’s also designed to be daisy-chained. You can buy a few of these lights for the same price of a larger light and connect them together like Christmas lights to cover a larger area. It comes with a 2-year warranty and a 30-day money-back guarantee.
Apollo Horticulture 300W LED Grow Light
Coming back to Apollo lights, 300W LED Grow Light is a small and light-weight grow light with roughly the face dimensions of a sheet of paper. It gives out a considerable amount of light for its small size. The panel gives off a broad spectrum of wavelengths, ensuring that it covers every phase of your plant’s life. This is not an inexpensive beginner’s light, but if you need a high-performing device on a smaller budget, this 300W LED grow light is a spectacular choice for growing your marijuana plant.
Global Star G02 300W

There are two built-in cooling fans which have a backup system to keep running even if one of their chips fails. The manufacturer provides a 1-year warranty that includes parts and services.
TaoTronics Hydroponic LED Grow Light
The TaoTronics Hydroponic LED Grow Light is ideal if you are a beginner in growing cannabis and want to master your craft without a hefty initial investment. If you only have one plant and need something that works for a small-scale grow room, why would you want to spend hundreds of dollars on a light for it? Right? This light might not last for your long-term plant growing goals, but it’s difficult to find a light that comes with a better value.
ABI 12W PAR38 Flowering lamp (to assist in blooming)

LED Grow Lights FAQs:
If you’re a beginner in growing cannabis or just want to improvise on existing knowledge, enjoy the read!
What is an LED Grow Light?
LED stands for ‘light emitting diode.’ It helps plants grow best when you plant indoors. It provides light energy that mimics the sunlight and affects these plants the same way sunlight does when plants are grown outdoors. It is environment/eco-friendly, user-friendly and provides various wavelengths of visible and invisible light including UV and IR rays that can directly enhance the growth and the yield of any plant grown under these lights.
How Do LED Grow Lights Work?
How can these tiny little lights mimic sunlight and help your plants grow better?
Plants usually tend to absorb more blue light than other colors like white or green light; hence, UV (ultraviolet) rays are the best to generate robust plant growth. While on the other hand, IR (infrared rays) act as the best catalysts for germination and blooming boost.
You can adjust the wavelengths according to the requirements of your plants’ growth conditions in the grow tent or area. To help stimulate the growth of plants in their vegetative phase, you can use UV rays to increase the cell division when the plants absorb the rays. The plants then grow quickly and result in more yield due to the increase in cell division.
If you want to treat your plant during the flowering stage, you can opt for the LED lights which provide IR (infrared) rays. The buds and apex of the plant absorb these promptly and this, in turn, helps them bloom quickly and heavily.
A LED grow light that has a wide range of wavelength options is always the best choice to buy so that you can adjust according to the effects that you need in your grow room. Various factors such as the amount of light output, type of light emitted (UV/IR), types of plants you want to grow, wavelength, Lumen per area, the height between plants and light etc., affect the growth and yield of the plant that you are growing.
Advantages of using LED Grow Lights:
Before the advent of LED grow lights, there were other methods in use like high-pressure sodium lamps, fluorescent bulbs, etc. But these methods were not good for small grow room owners who needed to have a small, tight or compact structure. The reason is these lights would occupy a lot of space due to the setup of all the equipment necessary to deal with the production of the huge amount of heat. They also needed to have a proper ventilation system to avoid building up of heat. These things made the process very hard for small grow owners who would have to invest a lot to grow their plants.
On the other hand, LED lights take up very less space, they don’t need their bulbs to be replaced, they don’t need ballasts to be managed, are eco-friendly, they don’t contribute extra heat and use half the electricity to run or sometimes even less than half the electricity to operate. They are very compact and easy to install too. You don’t need to have any specific knowledge to install these lights. You just need a proper place so that you can hang them above the plants in your grow garden at the required distance. They don’t need separate ventilation to be set up. They can work without any huge ventilation or large fan types.
They can also be installed adjacent to each other in order to give more coverage, thanks to their compact design.
The variety and control that they can provide are just awesome. You can adjust their wavelengths easily and can also change the modes for vegetative and bloom depending on the phases of your plants’ growth.
These factors combined with the great results that they give with a lot less hassle and price, have made us huge fans.
How Many Watts Do You Need for growing your plants?
First, you will need to find the area and the number of plants that you need to cover. Then you can figure out the exact wattage that you should have in your grow area
If you have 1 square foot of area that has one plant potted in it, then, the recommended wattage is 25 watts per square foot. If you have two plants in one sq. ft., then the recommended wattage would be 50 watts per Sq. Ft. and so on. So, if you consider an example of an LED grow light having a total wattage of 250 watts, you could grow 8-10 plants under it.
