1. Advanced LED Platinum Series P1200-
Editors Choice


In order to grow indoor cannabis, you need to provide a good amount of light to your plant for the best produce and a good yield. If allowed, cannabis grows the best in sunlight and the natural environment. Thus, it is very necessary for you to provide a near to about similar environment to your marijuana when growing it indoors.

The Advanced LED Platinum Series is a trusted name in providing the best led grow lights for growing marijuana indoors. So, does the P1200 model worth the money? Let’s find out.

The best feature of the Advanced LED platinum series lights is, they keep your grow room cool while providing your plants an adequate amount of light for their best produce.

The P900 offers 3 times more intensity of light as compared to the other competing grow lights. The Platinum series LED lights offers the highest Par/Lumen output per watt of any LED grow light.

The P900 LED includes 12 bands of light wavelengths which also include the infrared and ultraviolet spectrums which are invisible to see with a naked eye. This means, your plant is getting a light which is as close to the sunlight so that it gets that natural environment to grow.

The LED also has selectable Veg/Flower switches so that you can modulate the light according to the growing phase of your marijuana.

Including the all new upgraded aluminum fans and high speed whisper quiet fans with 8x speed, there is no doubt why the Platinum series P1200 is a great buy if you are looking for a reliable grow light for your grow room.

The 90-degree focusing lenses disperse the light so that it can reach till the canopy of your plant. This promotes the growth of your marijuana to a larger extent.

Now, the 1200 watt might give you a thought that it would be using a lot of electricity, you are absolutely wrong.

The P1200 can easily replace a 1000-watt HPS light at a full intensity by only using approx 515 watts of electricity. This means that running the P1200 LED in your grow room will cost you nearly half of your electricity bills as compared to running a 1000 watt HPS light. Isn’t it fairly super efficient?

The Platinum P1200 performs the best when suspended at 18-inches above the plant, it covers 6.0 x 5.5 ft of the coverage area. Well, this may vary depending upon the growth stage of your marijuana. You will have to modulate the height of the LED at different growing stages.

On an average, for sprouting, you can cover a larger area up to 4.0 x 6.0 ft. However, you will need to lower the light for greater intensity when your plant is at its initial growth stage.

Knowing the above features about the P1200 model, it is surely a great buy if you have a strong budget. The company provides a 5-year warranty with a 90-day return guarantee. This is foremost the best option if you are running having a big pocket

2. Advanced LED Platinum Series P900 LED Grow Light


Coming to the second LED light from the Advanced LED Platinum series, the P900 model is another superb grow light that will help you to produce a great quality cannabis indoors.

The P900 can replace a conventional 1000 watt HPS grow light easily while consuming just 557 watts of actual power.

Adding to the efficiency, it provides your cannabis with 100% usable light source with a motive to create maximum photosynthetic response so that the plants get near to about a replicate of a natural environment. This is considered as one of the best home essentials that everyone should have.

The LED supports the full growing process and you would not have to supplement any additional light for nurturing your plant. You can carry out a full-scale commercial operation as the P900 supports the growth of your cannabis from its seedling to its flowering level.

It is preferred to use the LED in multi-panel set-ups. The 5×5 grow tents or large hydroponics flood trays are preferred as many customers have claimed to use the LED in the same setup.

Like the P1200 model, the P900 also covers 12 different bands of a complete light spectrum. The mixture of UV and IR rays provides your plant with the aptest light conditions, somewhat covering for the natural sunlight in which the plant grows the best.

The different angles support the LED light to penetrate the canopy so that your plant can get a good nourishment till the deep root levels. You can use the 90-degree secondary focusing lenses for achieving the same.

The LED contains switches for Veg and Bloom. The Veg consists of purple/blue spectrum which mostly favors the development of the leaves. When it is engaged with the Bloom, the spectrum turns to pink/red with a heavy output.

You can keep the switch to Veg when you want a low-intensity light to help your plant reach the sprouting stage. This can be later changed to the bloom when you need high-intensity light to nurture the plant.

Thus, you can achieve a fully grown marijuana using the P900 model. It is definitely worth every penny on this high-quality product.

Talking about the reach of the Advanced LED series P900, when it is suspended at 18 inches height above the plant, the rays can cover and reach 3 by 5 feet easily. Its maximum reach is 4 by 6 feet. Now, many of you may be confused about the reach of the light.

Actually, at different growth stages of your plant, it needs a different intensity of light. In short, your plant would need less intensive light and you can cover 4 by 6 feet. However, at later stages of your plant such as the flowering stage, you would have to lower the grow light and bring it nearer to the plant as it would need a more intensive light.

On an average, an adult cannabis takes at least 1sqft in a 3-gallon pot. The Advanced Platinum Series P900 would be able to cover 12-24 pots at a time easily.

Here is a small video review which you can refer for getting the gist of the above features:

3. Advanced LED Platinum Series P300


Covering the last awesome LED grow light by Advanced LED Platinum Series, the P300 is suitable for those who have a small growing area. It is probably the best affordable LED grow light for the money.

As by now, you must have observed that the Platinum LED grow lights are one of the most powerful and energy-efficient grow lights available in the market.

They offer the complete 12-band spectrum which ensures that your grow room stays cool as well as yield maximum great quality marijuana. This is mainly because the Platinum series offers the highest PAR per watt as compared to any other LED grow light in the market.

The P300 is a good choice if you are looking for an affordable grow light. You can use multiple P300 LEDs in your grow room. They are perfectly suited for all growth phase of your marijuana i.e. from seedling to flower.

This combination helps in the growth of your cannabis as the light pattern is similar to the one provided by sunlight, under which the cannabis grows the best.

The 90-degree secondary focusing lens increases the intensity of your light so that it fully seeps down till the canopy, providing an optimal growth to your plant.

All the light chips are 3 watt LEDs, it is simply fantastic how the company has built the product using which you can achieve maximum light while consuming low energy.

Talking about the coverage area, the P300 covers slightly less than what is covered by the P600. It can cover about 4.5 x 3.8 ft area when the light is suspended at a height of 18 inches.

Also, like the other two models discussed above, the P300 also has selectable Veg and Bloom light spectrums so that you don’t have to worry about using any other grow light from the initial seedling phase of the cannabis till it turns into a full harvest.

The Veg spectrum features a purple/blue output which majorly favors the leaf development. Combine the Veg switch with the Bloom to enable the 100% panel power.

This would shift the spectral output to pink/red heavy output. Thus, you won’t need any other supplemental lighting as the P300 handles the full development of your cannabis.

LED Grow Lights Buyers Guide 2018

Now that you have seen the top rated LED grow lights, will now discuss the details on how you can buy the best LED grow lights for growing weed. For this, we shall have to start from the very basics and know about the history of LED grow lights, how did they came into existence and for what purpose.

History of LED grow lights

You can see from the image below how we have evolved from early 1800 starting from simple candle lights to modern day LED lights.

LEDs work on the primary principle of electroluminescence. The Monsanto Company was the first organization that produced the visible LEDs for the mass in 1968.


Usage of LED Lights

LEDs are being widely used in majorly all the lighting equipment. This is mainly because of the fact they are brighter than conventional lamps and consume less electricity.

From lamps to decoration lights, traffic lights to LED daylight lamps in automobiles, LEDs are used in all the major lighting gadgets.

LEDs have a better life as compared to CFL lights. Also, they emit less heat which was a major issue with the conventional lights.


How do LED Lights Work?

The process of working is quite simple. LEDs are semiconductors which conduct electricity in a circuit. They have two junctions- P-N junction. These silicon-based junctions play a major role in conducting electricity.

The N junction is the negative side and the P junction is the positive side. When electricity is passed, the electrons will pass from the negative to the positive side producing light.


What is the Significance of Different Colors?

As discussed earlier that most of the LED grow lights emit different colors which excessively support the growth of indoor plants, mostly cannabis.

This might be a little techy for you to understand. Just that, when we pass white light through a prism, you can view different colors on the other side of it. Similarly, we can modulate the color emitted by the LED lights by using different semiconductor elements.

Below is the detailed chart to show you how different colored LED lights are made using different semiconductor material.


Top Features of LED Lights:

1) They are super bright and would be best to provide your plants with adequate light.
2) LED lights cover a larger area as compared to conventional HID lights.
3) They are highly energy efficient meaning you would save a lot on your electricity bill in the long run.
4) They have a great lifespan and you can expect even an average LED light staying strong for more than 50000 hours.
5) They come with manufacturer warranty in the most cases which is a major point why people are shifting towards using them.

Now, let’s understand how to choose the best grow light for marijuana.

How to Choose the Best LED Grow Lights?

I have seen many people failing to grow a good quality marijuana due to stupid reasons. It’s not about spending the money or having a team to manage the growing process. Choosing the right equipment, especially, the LED grow light is important as it is something which directly affects the growing process of your weed.

Here are some important points to keep a note of while choosing an LED grow light:

The growing area you need to cover:

This the foremost thing that you need to consider while choosing the grow light. Some grow lights are capable to scatter through a small area while some are good to control the growing process of a big room.

The growing area will decide the number of LED grow lights you will need and which type of LED’s will provide you the best scattering and coverage. You can place the LED’s adjacent to each other to increase more coverage.

On an average, every 1 sqft of grow space needs 32 watts of actual wattage. However, this is an average number. The coverage varies from LED to LED.

For a general rule, you can refer to the below table to get the gist of how much wattage you will require on an estimate for a specific coverage area.

Number Of PlantsSquare FeetRecommended LED Wattage

Plant Growth Phase:

It is always preferred to use full-spectrum LED grow lights to support each phase of the marijuana growing process. You can modulate the light according to the growing phase of the marijuana. Many LEDs will come with a switching option which you can use to switch to the vegetative and blossom stage.

They would typically help you to grow your plant from the vegetative to the flowering stage without the addition of any external supporting lights.

However, there are lights which support only a specific growing phase of the plant. You could go for them although, you would have to change the settings according to the growth of the marijuana.

LED lens Angle:

Well, you may wonder how would the angle affect the growth of the marijuana. It doesn’t actually. The only thing it helps is in greater dispersion of light.


An LED with greater angles would cover more area as compared to an LED with less angle. Thus, we would prefer to go for LED lights with a greater angle as you would have to accumulate less growing lights in your space.

Your Budget

To be very frank, you should have a decent pocket if you are looking for a greater quality of marijuana. The good and reliable equipment come for a price. As you have already read the detailed full spectrum led grow lights reviews, you know that you can easily buy a good quality LED grow light between $100-$600. Well, there is always room for the expensive options but we would rather prefer you to stay within the above budget only.

Talking about the LED grow lights, the full spectrum would cost you more than the normal ones. Well, they are worth the price. In the end, the better quality of marijuana will also sell for a better price. Also, the full spectrum LEDs are energy-efficient which would be an added advantage in the long run.

You can plan and work on your budget. Grow lights are something where you should spend for the best. You could save a little here and there on the tents and other equips.

The best part is, most of the top LED grow lights covered in this post will come with a minimum warranty of three years. This means, once you buy the LED, you can stay tension free for three years as if any internal damage occurs, you can get it repaired free of cost.

On an average, the lifespan of an LED is more than 50,000 hours. Thus, they are truly worth every penny.

A good amount of light will help in a better yield, potency, and density of your plant which would, of course, be an advantage.

Benefits of Choosing a Full-Spectrum LED Grow Light

There are various types of lights that you could use for growing indoor marijuana. Most people use lamps and HID/HPS lights. Well, it is not wrong but, what if you could get a much better yield and that too in an energy-efficient manner.

The cannabis grows the best in natural sunlight. The plant actually needs a lot of light to grow in good density.

In order to produce the best yield, it is necessary that you provide your plant a natural environment. Full spectrum LED grow lights are changing the way of growing cannabis indoors. They mimic real sunlight and thus, have proved to be much better than the HID/HPS and fluorescent lights.

Using the full spectrum LED grow light:

  • You will get a better quality product.
  • Higher grain quality.
  • The cost of electricity is less over the time.
  • You will need fewer exhaust fans to circulate the temperature as the full spectrum lights run fairly cool as compared to HID and HPS lights.
  • The best part, you don’t need to replace them for 50,000+ hours. They have a much better life than the HID’s and normal bulbs. Also, most of the LED brands offer a minimum of 3 years of warranty.

After going through this list of top 15 led grow lights, you might be confused to decide which LED to buy in the end. Just to ease out the solution, we have come up with our recommended lights from the list under different categories.

So choose wisely and buy the perfect LED that would help you to grow a maximum harvest of marijuana from your grow room.
