Não, they emit less heat than HPS lights.
HPS produces a great deal of heat. Growers do in fact need to spend more money on additional water and cooling solutions. Além disso, the excessive heat produced by these lights may be dangerous, particularly if the ballasts or bulbs need to be changed.
You won’t have to worry about controlling the excessive ambient heat in your grow area if you use LED grow lights. Na realidade, compared to HPS lights, which emit 50% more radiant heat, most LEDs only emit roughly 25% of that heat. You may be confident that your LEDs use the majority of their energy to produce light rather than heat.
