How Much Heat Do LED Grow Light Produce?

November 27, 2021

The primary reason that LED grow lights produce heat is slight imperfections in the crystal structure of the diode. The electricity that passes through the diode that doesn’t get turned into light gets turned into heat.

The second reason LEDs produce heat is internal reflection within the diode. For extremely efficient LEDs, about 80% of the electricity gets turned into light and about 80% of that light makes it out of the diode (leaving a total of roughly 60% of the light to exit the diode). The light that doesn’t make it out gets turned into heat when it is re-absorbed by the diode.

The final reason we’ll discuss that LED lights produce heat is another form of light absorption. Much of the light that leaves your LEDs will get turned into heat when it eventually gets absorbed by some object in your grow space. This is what we meant above by a “closed system.” Assuming none of the light the LEDs produce will exit in your grow space, it will almost all eventually turn into heat.

According to the Law of Conservation of Energy, energy can neither be created nor destroyed, only change forms. So, when light is absorbed by the objects in your grow room that energy doesn’t disappear, it either gets converted into chemical energy stored by your plants in the form of sugars or it eventually turns into heat.

Ideal Temperature for Growing Plants Indoors with LED grow lights.

This depends on what you will be growing, whether you use supplemental CO2, and what stage your plants are in their development, but our recommendation for flowering/generative growth to have the daytime ambient air temperature around 83-850 F (28-29.50C). The nighttime temperature should be about 10 degrees lower than your daytime temperature.

Managing Indoor Grow Room Heat

While the heat from one or two LED grow lights is quite manageable, air circulation and ventilation are essential tools for you as a grower.   Irrespective of heat, here are some things that will happen to your plants if you don’t ventilate and circulate your air: dust will settle on your plants and reduce their photosynthetic efficiency, humidity will rise reducing transpiration and increase mold pathogens, and carbon dioxide levels will drop lowering your photosynthesis rate.  Not only should you ventilate and circulate your air, but filtration is also recommended to reduce smells, dust, and the exchange of pathogens.
