Although they are incredibly efficient, LED lights still produce some heat that needs to be properly managed. This is a result of the energy being transformed and heating up the lamp. Each watt of electricity produces some amount of heat regardless of LEDs output efficiency. For example, an LED bulb that consumes 8 watts would generate a heat of 27.28 Btu.
When talking about heat emission and led grow lights for grow tent we should mention the role of the so called heat sink, an integral part of the grow light that helps the heat escape. Heat sinks are made so that they absorb the heat and prevent it from going to the diodes. This is a vital piece of the equipment because it helps it last longer, preventing any changes in the light spectrum and emission. At Advanced LED we`ve developed a special patented Dual Heat Sink system and a ColdFlo Heat Dissipation technology that reduce the emitted heat with more than 50%.
What is the best approach to keeping light arrays cool while keeping costs low?
Water cooling is not 100 percent efficient at transferring heat, at least not yet. Locating the power supply outside of the growing area may give a grower half of the heat savings that could be realized with a water cooled system, but what is gained in lower cooling energy is lost in line losses of long electrical cables.
Including fans (convection) to produce currents of cooling air is an effective way to manage heat issues, but fans introduce a moving part into the system. Moving parts typically break down long before LEDs fade.
However, if you must purchase a unit with fans in it, make sure the led grow lights for weed have a long warranty and the fans are rated for a lifetime that exceeds that of the LEDs.
While LEDs generate heat, there are important differences between traditional lighting technology and LED lights:
HID grow lights (metal halide, high pressure sodium and ceramic metal halide / light emitting ceramic) require heat to produce light by arcing electricity through selected gasses, making them extremely hot, to the point the gasses glow.
Because LEDs aren't wasting energy producing light plants can't use, we can use less energy overall to get the same (or better!) growth from plants. Less energy consumed means less heat; for a given growing area, LED lights will put off less heat than any equivalent artificial light.
Summing Up
In short, yes, LED grow lights do create heat. But so much less than any other form of grow lighting.
The reason for keeping them at a sensible distance from your plants is much more about sheer brightness and intensity than any real danger of overheating your plants. As you lower them towards your plants, the intensity of light will cause problems long before the heat emitted ever does.
So just follow the manufacturer recommendations, make any necessary adjustments for the specific strain you're growing, monitor heat and humidity in your grow space (as usual) and you'll have no problems with your LEDs.
