What to Look for in an LED Grow Light​

LED fixtures with an adjustable output spectrum

Since LED lights come in a variety of colors, you need to be able to control the light output spectrum depending on what plants you are growing or what season you are creating.

Basically, you will be able to match the LED bulb colors to the flowering season you are working with or the season you want. When you vary the light output, you can follow the growing circle of the plant by simulating seasonal light changes.

A high power cooling system for the LED fixture

It is necessary to cool high powered LED fixtures just like computer CPU fans. The LED fixtures themselves do not radiate heat and so they need a metal pad that gives the fixtures a way for the heat to be removed from the LED.

What you will need to look for is a fixture that is mounted on a metal core printed circuit board (or MCPCB). This is space-grade technology that operates at high temperatures.

A fixture that has a circuit board mounted to a large enough heat sink; it should also have several fins

The fins help the circuit board spread out the heat faster and having more than one fan will stop any failures that only having one fan may cause such as overheating and damaging the fixture.

LED fixtures that has a constant current driver circuit

The electronic current circuit converts AC power to the right voltage and level of current that the LED fixture can withstand. This allows the circuit drive to provide a constant supply of current and support the strength with corresponding temperature changes.

Benefits of Using 'LED' Grow Light

What are the benefits to LED lights in comparison to other types available? Led light benefits are best seen when compared to what other lamps produce.

These are a few of the benefits of using LED Grow Lights:

Design Efficiency

LED Grow Lights are well known for their space saving designs. Other types of grow lights require a lot of space as well as additional equipment to work well. LED lights allow you to have better space utilization since they are small and do not require extra equipment to run.

They are also easier to move around and change their positions with some lights designed to link together so they don’t require extra cords.

Light Spectrum Optimization

With LED lights, you are able to fine tune your light spectrum producing the best light for plants to grow through various stages in their cycle. You can even concentrate energy on specific frequency bands so you aren’t wasting energy on light that is in an unusable area of the spectrum. LED lights provide the correct kind of light that plants need to thrive.

Other lights do not have the ability to fine tune their spectrum so the light that they produce is all you get.

Energy Efficient

Another benefit of the LED lights is that they are energy efficient. They save you tons of money on your electricity bills each month. They are very reliable and a great way to save energy.

Long Term Use

They also have a long lifespan. Many of these LED lights will last between 50,000 and 100,000 hours before dying. Comparable lights will last only about 20,000 hours.

They also run at a low temperature so they do not heat the room too much risking changing the room temperature and possibly destroying your plant growth.
