Things to consider before buying

There are a couple of things you absolutely need to consider before choosing the best LED grow light:

 

Reviews Of The Best Carbon Filters

Runner Up: Vivosun 4 Inch Air Carbon Filter

These lights have great design and also have high PAR value across your canopy. King Plus is a relatively new player in the market, but they have come out swinging with this light. Featuring 10W Double Chips, which are brighter more efficient than traditional 3W and 5W LEDs, this lamp is scientifically engineered to keep the balance of the PAR & lumen output and coverage. It gives BESTVA a run for it's money, beating it on $ / watt, but keep in mind you typically get what you pay for and you can expect the BESTVA to last longer.

Great for grow tents, a room, and greenhouses. This is also a great product for you if you want something that’s easy to install as it comes with everything you need (hangers, cords, carabiners). 

Customers rave about how fast the plants grow and how potent they become. This light produces very high PAR at a very low wattage. Great for energy consumption and for the price, this light gets the job done.

CoolGrows 4 Inch Air Carbon Filter - Good For Beginners

 

For those who love the P600 but don’t have quite that large of a budget or size of a grow tent, the Advanced Platinum Series P300 is a great runner-up. This is definitely a more affordable LED grow light that offers many of the same benefits as the P600, but at around half the price.

Its coverage is about 4.5 feet by 3.8 feet at an 18-inch height, perfect for compact grow areas, or when used in combination with additional lamps for larger areas. This light panel effectively replaces a 400W HPS light, while only actually using 180 watts of power – making it an energy efficient alternative to a traditional light. It’s just perfect for the small home grower. Just as the P600 represents the higher end of the market, this is still a serious piece of equipment–practically a steal for the amazing coverage you get.

This is a system that has a great high PAR per Lumen output of any other LED grow light panel I’ve seen. What does that mean? Well it means the panel gives off about 2 to 3 times the intensity of other grow lights.

More importantly, it has an 11 band spectrum that gives your marijuana plants the most nutritional value including those needed from UV and IR. The light chips are all 3W LEDs, and as I’ve mentioned before, the best 3-watt panels have an additional lens to focus the light a bit more. This panel comes with a 60-degree lens and secondary 90-degree focusing lens to give more intensity for plant growth.

The chips in this lamp are also replaceable and another reason for the slightly higher price tag. This means you can always keep that 400-watt output, even when a chip blows. Just order the one chip and replace it when it arrives from the manufacturer. With a 5-year guarantee, PlatinumLED offers security to their customers.

Amagabeli 4 Inch Carbon Filter - Versatile

Morsen is a top brand and you are looking for top quality. These lights typically run bigger and more powerful than most other LEDs. These lights have low energy consumption and really run great no matter what stage of plant growth you are in.

It’s a very high quality product and trusted brand for a very good price (especially when you compare to more expensive options out there like California Lightworks). Can be used in house garden, pot culture, sowing, a greenhouse + more. This particular product comes with a free power cord and free hanging hook. The lifespan for this light is particularly long and runs >50,000 hours and you should be good to go with the 3 year warranty in case anything breaks. This is a very safe option as it is also 3x to 5x the efficiency than HID & HPS lights.

VIVOSUN 6 Inch Air Carbon Filter 8 Feet of Ducting - Most Trusted Brand

 Everyone knows the Apollo brand. This LED light produces very little heat because of the compactness of the product.
The Apollo brands are typically lighter in weight and this light is easier to mount inside grow tents in particular. The price is very good for someone that isn’t looking to spend much but is looking for a recognized brand and quality.
This particular product has been known to provide great light no matter what stage you are in (veg or flower). The Apollo light will have enough lumens to do whatever your plant needs to do with little to no heat and easy installation steps for you to follow. Plants respond well and these lights consume less power with great durability.
When we tested this product ourselves, we did notice that the fan did error on the hot side (despite the fact that it has fans). This light does have a lifespan of ~50,000 hours, but does lack a power switch - which can be an annoyance to some growers. What we have noticed is that this particular light is great for medium sized, simple set up.

iPower 4 Inch Carbon Filter + Kit - Economical Choice

The first thing comes to mind for this product is the price. For what it costs, you’re getting a great product that has high output and is durable.The intensity of the light is great especially considering it is very power efficient with  great spectrum on the light. The fans on this light also help keep the temperature down dramatically and is great for a beginner indoor grower who wants to test a light at an affordable price. 

The recommended height to plant distance is around 12”-50” depending on the growing stages. The item is light at around 5 pounds and is extremely bright given the size. This light may not speed up the growing pace for your plants like some of the more expensive options, but it’s perfectly serviceable.

Despite the fact that this light doesn't offer the full spectrum setup, it is still great for growth (especially if you are a beginner doing a basic set up). You'll need to purchase basic accessories that typically don't come with the cheaper LED lights (timer).

Growneer 4 Inch Carbon Filter - Low Budget Choice

->

California Lightworks 440W LED Grow Light definitely falls under one of the more expensive lights on our list, but this is one situation where you get the results you pay for. This particular unit comes in a bright red color – a stark change from subtly-colored light panels from other manufacturers.

The light is a bit more intense than those with 3W chips, as this uses 5W LEDs instead – 88 of them. The optics are all jewel-quality glass focused at 90 degrees. In addition, it has two 15W UV-B tubes to enhance growth at the flowering stages. This panel runs cool and quiet with its built-in fans, and it comes with a 3-year warranty. California Lightworks is always a very well-recognized brand in the LED community, so you can't go wrong here. It's also one of the most popular lamps for producing flower for CBD oils and tinctures.

Phresh Filter - Most Expensive

This light does not get loud nor does it get loud. When we tried this light, it exceeded our expectations, especially for an “inexpensive” light.

The brand has been around for a while hence why they are able to make the installation easy for just about everyone (they've been in business for over 7 years and are a well-known brand in the industry). This light was definitely one of the more energy efficient compared to some of the other lights that we tested (especially the cheaper ones). We used ours in a 4x4 canopy and it worked great as the light was able to penetrate all open space.

This light does have the switch so you can toggle between veg/bloom mode, making this one of the premier lights for compact spaces. It can also be used for medium-sized spaces, so it's an extremely versatile. It has the full spectrum of blue, red, and white for the veg and flowering stages.

PrimeGarden Carbon Filter + Kit - Best Kit Value

This is a very highly lauded grow light with some of the best longevity we have seen in the LED category. G8LED has had many iterations and has been producing LED grow lights for 8 years. Many bloggers and review sites describe this light as the cream of the crop, and it has been awarded some high accolades by major publications. 

These lights are for both vegetative growth and flowering and provide intense lighting for 24 square feet of canopy. The light emits low heat and requires low electricity usage. If you want to graduate from a beginner set up to a professional production, this is the perfect light for you.

You may think it is a high price tag, but the money you save through electricity costs and the durability of this light will get you a long way.

Oh and by the way? High Times rated this the best LED light of 2016.

VIVOSUN 6 Inch Carbon Filter - Best ROI For Small Grows

This is great bang for your buck. One of the lowest priced option of the bunch and great energy savings. With only 269 watts pulled from the outlet, the light is able to still give high PAR value (equivalent to a 600W HPS/MH) which will allow for very valuable savings after a few months, so you should be able to get your $ back soon.

These lights deliver 12 bands including 2 IR and 2 UV through optical lens to maximize the PAR per watt. The VIPARSPECTRA lights are great for the veg cycle and you should see results quickly with the brightness of the light. The lights themselves are very powerful, but don’t give off the same kind of heat as some of the other more expensive brands/lights on this list.
