How To Choose the Best LED Grow Lights: A Buyers Guide

LED grow lights are becoming more and more prevalent in both industrial grows and home grows. Their recent spike in popularity is likely due to their superior results and increased publicity in mainstream media. Many years ago it used to be the case that only big gardening companies could afford to run indoor growing operations, but with a fall in price and the introduction of smaller models they have become available to the general public.

Growing plants indoors can return a far greater yield than growing outdoors, mainly because of the constant light in the right spectrum, which the top rated grow lights will deliver. Starting your own indoor garden is going to require investment both in purchasing components and also the cost of running them. So it’s important that you pick the right lights for your grow and ones that are going to last for as long as possible. When you are working with bright LED lights it’s important that you wear good quality eye protection, this isn’t optional. Apollo Horticulture make a great pair which will protect you from all UV rays and will reduce eye strain.

What should you look for in grow lights?

With a huge array of products available on the market it can be hard to decipher what the differences are and which ones are the best LED grow lights for you.

Cooling Systems

Grow lights are designed to prove your plants with all the light they need, but as with all lights they produce a lot of heat. This heat if directed to your plants can harm them and inhibit their growth. Also, the hotter an LED is the faster it is going to break. Cheap grow lights are notorious for emitting a large amount of heat and for breaking quickly.

Instead, you should look for products that include heat sinks and fans that are used to absorb the heat instead of sending it out and then fans which cool the lights down. When you look at the packaging of grow lights you’ll often see that they are mounted on MCPCB’s, these are circuit boards that contain a solid metal core. These conduct far more heat than traditional circuit boards, preventing them from breaking under high temperatures. MCPCB’s are crucial.

Adjustable LED’s

Just like the radiation from the sun can differ, so should your grow lamps. A good led grow light will allow you to control the intensity of each of the different led colors. This allows you to simulate outdoors season changes and thus promote growth or inhibit it.

Some plants will require different spectrums of light, if you have the option to adjust the levels of each color of LED then you’ll be able to give your plants exactly what they want. An adjustable output is an important feature especially if you plan on using the grow lights more than once.


The LED’s are powered by an intricate circuit board containing many different components. The board will take the AC power that comes from your house and convert it to DC power that will power the grow lights. It’s important that the DC current is constant regardless of the LED’s voltage or temperature. If you don’t pick a grow light with constant current then you should expect it to break far earlier than other models that do use constant current driver circuits.

Advanced Platinum Series P300 300w

PlatinumLED are one of the best companies in the indoor gardening world, with one of the most superior grow lights on the market. Their LED’s have the highest output per watt of any grow light, meaning a greater intensity for the same cost. With a complete 5 year warranty there is no reason not to try them out. You won’t be disappointed.

The P300 comes with a inbuilt vegetable/flower switch meaning that you can make quick adjustments to the output spectrum. As detailed above the heat sink and fan system is crucial to a good grow light. The P300 includes 2 super quiet fans and an aluminium heat sink that will prevent the system from overheating and causing damage. With this system you can be assured that your plants or flowers are getting exactly what they need.

This light had a huge spectrum, with 11 different lengths of light from 380nm all the way up to 760nm, practically ensuring that your plants get everything they need to grow as fast as possible.
