Features to consider when LED grow lights

Here are some of the crucial features you have to be extra keen on when choosing an LED grow light if you don’t want to regret your decision:


8 Best 1000-Watt LED Grow Lights to Maximize Growth Rate

This is an essential factor as it determines the quality of light your plants will be getting. You need to consider the color of the light and the customization options available. Be sure to go for white LEDs as they mimic sunlight and make it easier to inspect the plants. As for the customization options, go for grow lights that have the BLOOM and VEG modes for ease of use and low cost of energy.

Light intensity

To get the optimal light for your plants go for a grow light with 5 to 15-watt diodes like the Sunraise 1000W LED Grow Light above. It will have a balanced spectrum with a high PAR/Lumen output that would benefit your plant.

Wattage draw

This determines how much you will be paying in your electricity bill. Most grow lights use between 150 and 180 watts. The MARS HYDRO TS 1000W Led Grow Light above uses only 150W which is super great energy efficient.

Coverage area

This is another crucial factor, especially if you have a large indoor garden. You need to ensure the light from your LED can cover the entire area to benefit all the plants equally.

Input voltage

This determines the wattage draw of a grow light. The higher the input voltage the higher amount of energy the grow light will be using.

Cooling system

When used for extended periods, LED grow lights can be prone to overheating. This is why they have efficient cooling systems that include cooling fans, aluminum heat sinks and vents that ensure maximum airflow.
Some like the MARS HYDRO TS 1000W Led Grow Light have a fan-less cooling system thus the quietest and still get to dissipate heat sufficiently with an aluminum heat sink.

Dimensions and weight

The stronger the light the further it needs to get hung. For 1000-watts LED light you can hang it at least 15 inches away from your plants.

No. Overheating is one of the main reasons why lights catch fire. LED lights do overheat but they produce light at a very low heat compared to other bulbs.

It is not advisable to leave LED grow lights on for 24hours. Plants need to carry out the respiration process and 24hrs of light can prevent them from doing so. 12 to 18hrs should be enough.
