What are the best LED grow lights for cannabis in 2019
As more States have moved towards the legalization of marijuana led to increased indoor growing of Cannabis. And in a bid to maximize yields, growers of weed have resorted to using full spectrum LED grow lights as they consume less electricity, produce minimal heat and produce high marijuana yields.
The VARASPECTRA Reflector Series 600W panel can be switched between vegetative and flowering stages as needed. Perfect for a small grow tent.
Optimally configured with red, blue and white LEDs for a total of (120) 5 watt EpiLEDs diodes for all stages of growth leaning more towards the blue spectrum for the vegetative stage.
The light produced is so bright that it’ll be unwise to stare at it with the naked, unshielded eye.
The VIPARSPECTRA Reflector Series 600 watt panel has two 4.72″ fan for cooling. The fan draws air in thru the side vents, across the heat sink and blow out the top. This is petty standard with other comparable LED grow panels.
Indoor Garden Coverage
The VIPARSPECTRA Reflector Series 600 is perfect for a small garden 3×3′ with a maximum area of 4×4′. Compares to an traditional 600w HPS.
Expanding your indoor garden is relatively easy by adding additional fixtures by daisy chaining them together. No special cables are needed. Just plug the power cable from one unit into the other as shown below.

2. Advanced Platinum Series P600
Advanced Platinum Series are among the most powerful LED grow lights available to consumers today. Yet this is just one of the reasons why we think that this is one of the best on the market. First of all, let’s talk output. Offering the highest PAR per watt of any grow light, it also features a 12-band spectrum. This means that you can expect excellent yield with minimum power usage and heat. So if you’re looking for LED grow lights that are high in efficiency, you can’t go wrong with the P600. The dimensions of the unit are 36” x 8” x 3”. Therefore, it can provide 6ft x 4ft coverage at a height of 18-inches. If you’re able to stretch your budget, go for several of these units and you’ll be able to grow some impressive crops!
The 12-band spectrum produced by the P600 is the secret to the success of this product. This offers a complete blend from low UV to high IR which is exactly what your cannabis plants need. The LEDs used are US-made so you can expect them to be of high quality. This is reflected in their lifespan which is some 100,000 hours (up to 8-10 years). When you combine all of these advantages with the 5-year warranty and 90-day money back guarantee, you’ve got an unbeatable combination! The only drawback is the price which may be out of reach for those on more limited budgets. We think they’re well worth the investment.

Unlike other manufacturers, Black Dog LED PhytoMAX-2 600 uses the actual wattage in their product names. Thus, the Phytomax 600 actually consumes 600 watts and is equivalent to using a 900 watt HPS.
Black Dog LEDs feature their Phyto-Genesis Spectrum™, which they developed after 5 years of extensive research. It includes light from 365 nm to 750 nm. That means it has all the wavelengths from UV-A to IR—basically every color of light plants need during any stage of growth.
Black Dog PhytoMAX-2 lights do not have separate modes for veg and bloom. As for the effectiveness of Black Dog’s spectrum: it has outperformed every other type of light (HPS bulbs, standard MH bulbs, light-emitting ceramic MH bulbs, induction bulbs, fluorescent bulbs and “white” LEDs) in equal-wattage tests.
This light will give you a 4.25 by 4.25 foot coverage area during flowering and a 6 by 6 foot coverage during veg.
Black Dog fixtures distribute their light much more evenly throughout the coverage area, so while you get less power in the center, you get more power on the outside of the coverage area and more average power overall.

I don’t have BESTVA or KINGLED on my list because they both are made by the same company and they do not reply back to their customers. I bought a King Plus 1200w light from them on their Kingled website and the photo of the light shows it with the Veg and Bloom switches, but the one i got does not have those switches. so i’ve sent two emails to them in the past thee weeks and they never replied back. On their website “Contact Us” they say they will reply back in 24 hours, that is just a lie. I imagine their 3 year Warranty is just a lie also,because they do not reply back to customers,so your Warranty is no good. All they care about is just getting your hard earned money. So i will not recommend them.
What you need to look for when buying your LED lights
When buying led grow lights for your marijuana growing needs, there are a number of things you need to consider. Below are the main factors to consider in your search for the best LED grow panel for marijuana.
Size of grow space and power
When buying a panel for indoor marijuana it is important to consider the amount of indoor space you have dedicated to the growing of marijuana. The space you have dedicated to the growing of weed will dictate the size and number of growing panels you require. As a basic rule of thumb, the minimum wattage you should get is 50 watt. With a 50 watt light, you can comfortably grow weed in one square foot of space.
Therefore, the minimum grow space to power ration is 50 watt per 1 square foot of space. That being said, it is important you calculate the size of the area that your indoor weed occupies. For example, if your marijuana occupies 4 square feet of space then you will need a minimum of 200 watts.
If on the other hand, your marijuana takes up 16 square feet of your indoor space go for a more powerful 800 watt light. The general rule is that more wattage results in more yields. Thus, it is wise to go for most power you can afford.
As with any other appliance, price is an important factor to consider when choosing a panel for growing marijuana. However, it should never be the main factor that influences your decisions when selecting led grow light kits. The main reason why LED lights are in so much demand is they save on electricity costs and bulb replacement costs.
If you are looking to supplement your existing grow lights, panels are great the way to go since minimal additional heat is generated. There are other cheaper led grow light options available that you can take advantage of if you are growing marijuana on a small scale, panels are the only way to grow indoors.
Nevertheless, light emitting diode panels are priced differently. Thus, there are those that cost upwards of $1000 and there are others that cost as little as $ 100. Needless to say, a led grow light that costs $ 1000 will be more powerful than a $100 panel. As such, it is important to evaluate your light needs vis-a-vis your financial position. If you are a small scale grower looking to increase your yields, a $100 panel will be ideal.
Contrastingly, if you have more marijuana to grow a $1000 led grow light will do a better job. A cheaper light will be incapable of providing light efficiently. To get a balance between price and performance go for a mid-range led grow light. These are lights that cost between $200 and $500. These lights offer more power compared to $100 grow lights but are less expensive than $1000 kits.
In the past, you only had two options to choose from, white and panels of specific colors, such as red or green. Today, there are more options to select from.
However, all the options available can be categorized into two broad categories, white LEDs, and multi-band LEDs. White LEDs mimic the rays of the sun and are said to be more closely related to natural sunlight. Therefore, there are many people who prefer white LEDs to multi-band. So which of the two is the right one for you?
Well, it all depends on your preference and what you are growing. The biggest problem with white light emitting diodes are that they emit green and yellow spectrums, which are not required by plants.
Therefore, these lights are less efficient as the green and yellow lights go to waste. Multi-band lights, on the other hand, do not have this problem, making them more ideal for large scale growing of marijuana. Unlike white light emitting diodes, multi-band panels produce different spectrums including white spectrums. Therefore, they are able to emit the specific spectrum needed by marijuana plants.
Most full spectrum LED grow lights have customizable spectrums. This means they can be programmed to emit a specific spectrum. The benefit of this is that you are able to save on energy costs without exposing your plant to unwanted spectrums. For efficiency and flexibility, choose an LED grow light with more spectrums.
The more programmable lights an LED grow light is able to produce the more efficient it will be. This is because marijuana plants grow in stages and each stage requires a different spectrum. The first stage is the vegetative stage, which takes between 1 week and 40 days and the second is the flowering stage which takes about 40 days. While the plant is in the flowering stage it will require a different light than when it is in the vegetative stage.
What’s PAR and Why It’s Important
PAR stands for ‘Photosynthetically Active Radiation.’
And although some LED light manufacturers (wrongly) use the term PAR when talking about a light’s intensity, PAR is not a way to measure the intensity of your light.
PAR is the range for all the different wavelengths/colors of light that plants use for photosynthesis.
For your plants to grow optimally, your LED light should have all the different wavelengths/colors of light that makeup PAR. But especially important are:
The blue wavelengths (for vegetative growth), and;
The orange/red wavelengths (for the flowering process).
Luckily, most LED manufacturers are aware of PAR and design their lights in such a way that most of the wavelengths/colors of light that fall within the PAR-range are present.
And the lights in this list have specific vegetation/flowering settings with optimized spectra for that particular stage in the growth cycle. and, you can quickly activate these specific settings with a simple switch.
This is also the main reason why LED lights are more efficient than HID lights (HPS and MH).
HID lights emit ALL the different wavelengths/colors all the time. This even includes wavelength/colors that fall outside of the PAR range!
What this means is that HID lights waste quite a lot of electricity, because they’re using power for colors/wavelengths that fall outside of the PAR range and thus are useless for your plants!
If you get the right LED light, your light will mostly have the wavelengths/colors of light that fall into the range of PAR and wavelengths that fall into the deep and far-red spectrum (which are essential for the Emerson effect). Your light will largely emit light that’s actually being used by your plants for photosynthesis. This way, little to no electricity goes to waste.
PAR doesn’t say anything about the light’s intensity (in all these different wavelengths). Your light’s intensity is key to rating a grow-light and getting strong plants with monster yields as well.
