Editors Choice

Advanced Platinum Series P1200 1200w 12-band LED Grow Light - DUAL VEG/FLOWER FULL SPECTRUM

To grow cannabis indoors, you need to provide the right amount of light to your plant to produce better yields. If allowed, cannabis grows the best in sunlight and the natural environment. But it can still grow very nicely indoors provide a well-lit environment to your marijuana to grow indoors.

Check out our in-depth review here.

The Advanced LED Platinum Series is a trusted name in the world of growing marijuana indoors. But does it live up to its price tag?

The best feature of the Advanced LED platinum series lights is that they keep your grow room cool while providing your plants an adequate amount of light. It includes 12 wavelengths of light including infrared and ultraviolet spectrums which are invisible to the naked eye. This means your plant is getting light that is as close to natural sunlight as possible in an indoor environment. These lights also have selectable Veg/Flower switches so that you can modulate the light according to the growing phase of your plant.

Their all-new upgraded aluminum fans include high speed whisper quiet fans with 8x speed. There is no doubt why the Platinum series P1200 is an excellent buy if you are looking for a reliable grow light for your grow room.

They use 90-degree focused lenses that disperse the light far enough to reach the canopy of your grow room and reach all your plants within a 4×6 radius.

It might seem like a 1200 watt bulb would cost you more in electricity, but using a higher watt bulb will save you electricity costs in the long run. The P1200 can easily replace a 1000-watt HPS light at full intensity and only uses approximately 515 watts of electricity. This means that running the P1200 LED in your grow room will cost you nearly half in electricity costs compared to using a 1000 watt HPS light.

The Platinum P1200 performs the best when suspended at least 18-inches above the plant. At this height, it covers 6.0 x 5.5 square feet of the growing area. The area might vary depending on the growth stage of your plant, so you may need to adjust the height of the lights at different growing stages. When the plant is at its initial growth stage, you can use a lower intensity light.

If you have the budget, it’s worth it to spring for the P1200 model. It comes with a 5-year warranty and 90-day money-back guarantee.

Here’s a short video that covers even more features of the Advanced LED Platinum Series P1200.

It offers three times more intensity of light compared to other competing grow lights at the same price range. The Platinum series LED lights provides the highest Par/Lumen light output per watt of any LED grow light we’ve seen. 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 a light source that creates a maximum photosynthetic response. With this light, plants experience a near replicate of a natural environment.

This light supports the full growing process, and you won’t have to supplement any additional lamps for nurturing your plant. With the P900, you can carry out a full-scale commercial operation since it supports the growth of your plant from seedling to flowering.

When using this light, it’s recommended that you use multi-panel set-ups. Most P900 users have 5×5 grow tents, or sizeable hydroponic flood trays as part of their setup to get the best results.

Like the P1200 model, the P900 also covers 12 different rays of the light spectrum. The mixture of UV light and IR rays provides your plant with the best light conditions, and mimic natural sunlight. The adjustable angles of the light support help to penetrate the canopy of your grow room so that your plant can get complete nourishment and produce deep roots.

This LED also contains switches for Veg and Bloom phases. The Veg phase consists of a purple/blue light spectrum, which mostly favors the development of the leaves. During the boom phase, switch to the pink/red range for a better output. You can use the dimmable switch when you want a low-intensity light to help your plant reach the sprouting stage. This can be changed to the bloom setting when you need high-intensity light to nurture the plant.

When it is suspended 18 inches above the plant, the rays can easily cover and reach 3x5feet and up to 4×6 feet at the right angle.

The P300 is a good choice if you are looking for an affordable grow light and the right choice if you want to use multiple P300 LEDs in your grow room. They are ideally suited for all growth phases of your plant.

It’s no secret that full-spectrum lights are better for plant growth. The P300’s success is due to its combination of 12 full-spectrum light bands offering a complete spectrum of light from ultraviolet to upper IR. This combination helps the growth of your cannabis because the light pattern is similar to the one provided by natural sunlight.

All the LED chips in the lamp are 3 watt LEDs and help you achieve maximum light while consuming as little energy as possible. LED lights that contain COB LEDs (Chips on Board) are lighting packages that save more energy and have an even higher lifespan than regular LEDs.

LED Grow Lights Buyers Guide 2019

Now that you’re familiar with the top-rated LED grow lights on the market, let’s talk about how to choose the right LED grow light. To tackle this subject, we’ll need to briefly dive into the origin story of LED lights and what makes them such a popular option among marijuana growers.

History of LED grow lights

You can see from the image below how much we have evolved from the early 1800s. The lighting industry has come from simple candle lights and oil lamps to the modern-day LED lights we see now.

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

Usage of LED Lights

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

From lamps to decoration lights, traffic lights to headlights, LEDs are used across industries and devices as a bright and energy-efficient option to other lights. LEDs have a longer lifespan compared to CFL lights, and they emit less heat, which was a significant issue with conventional lights.

How do LED Lights Work?

LEDs are semiconductors which conduct electricity in a circuit. They have two junctions — P junction and N junction. The N junction is the negative side, and the P junction is the positive side. These silicon-based junctions play a significant role in conducting electricity. When electricity is passed, the electrons will move from the negative to the positive side producing light.

What is the Significance of Different Colors?

Most LED grow lights emit different colors, which excessively support the growth of indoor plants, like cannabis.

When white light passes through a prism, you see different colors on the other side of it. Similarly, we can modulate the intensity emitted by the LED lights by using different semiconductor elements within the light to create different colors.

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

The Benefits of LED Lights:

1) They are very bright and are the best choice to mimic natural sunlights for your plants.

2) LED lights cover a larger area compared to conventional HID lights.

3) They are highly energy-efficient, meaning you will reduce your electricity bill in the long run.

4) They have a long lifespan. You can expect an average LED light to stay strong for more than 50000 hours.

5) They usually come with a manufacturer warranty, which is a major reason why people are shifting towards using them.

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

How to Choose the Best LED Grow Lights?

You don’t need to spend a lot of money on lights to grow good quality marijuana. It’s more about making the right choices and following the correct processes that will produce high-quality cannabis plants.

But even though you don’t need to spend a lot, you do need to choose the right lights that work will your grow room and set up.

Here are some essential points to keep in mind when choosing an LED grow light:

The growing area you need to cover:

This the most important thing to consider when selecting the grow light. Some grow lights are capable of covering through a large area while others are better suited for smaller grow spaces.

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

On average, every 1 square foot of grow space needs 32 watts of light.

Plant Growth Phase:

It is always recommended that you use full-spectrum LED grow lights to support each phase of the marijuana growing process. This way, you can modulate the light according to the growing phase. Many LEDs come with a switch that lets you jump between settings for the different phases of growth.

Most lights will be able to help you 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. Decide if you want the convince of a single light that can switch between phases or the power of an individual light for each specific stage.

LED lens Angle:

You might wonder how the angle of light affects the growth of marijuana. It doesn’t make as much difference as you think. The primary way it impacts your plant is that it helps disperse light over a greater grow area.

An LED with the option to change angles will be able to cover more area compared to an LED with fewer angle options. This is why a lot of growers prefer LED lights with more adjustable angles so that their light can adapt as their grow room changes.

Your Budget

Like most things, the highest quality and most reliable grow lights come at a price. We’ve covered quite a few affordable full-spectrum LED lights in our review, and we stand by those options. However, the higher your budget, the more you will be able to get for your money.

When it comes to LED grow lights, full-spectrum lights will cost more than standard lights. In the end, better quality marijuana will sell for a better price. Having a higher quality light that produces a better plant will be worth it in the long run.

The good thing is that most of the top LED grow lights covered in this post come with a minimum warranty of three years. This means, once you buy the LED, you can rest assured that you won’t have to replace it for at least two or three years depending on the brand.

On average, the lifespan of an LED is more than 50,000 hours, meaning you’ll get plenty of use out of your light regardless.

Benefits of Choosing a Full-Spectrum LED Grow Light

There are various types of lights that you could use for growing marijuana indoors. Some people choose standard lamps and HID/HPS lights. But if you’re serious about growing, LED lights are the most reliable and efficient choice.

Cannabis grows the best in natural sunlight. The plant needs a lot of light to grow in proper density. To produce the best yield, it is necessary that you provide your plant with a natural environment. Full-spectrum LED grow lights are changing the way people grow cannabis indoors. They mimic real sunlight and, have proven to produce better plants than HID/HPS and fluorescent lights.

To summarize the benefits of full-spectrum LED grow lights:

  • Produce higher quality plants
  • Higher grain quality
  • Reduced electricity costs over time
  • You will need fewer exhaust fans to circulate the temperature
  • They last for 50,000+ hours; a much better life than the HID’s and normal bulbs
  • Most LED brands offer a minimum of 3 years of warranty
