Quiet Operation

Inside of the unit, there are large heatsinks and ultra quiet fans that are designed to keep it within the proper operating temperature while it’s turned on. Naturally, LED panels tend to run much cooler than your standard metal halide, high pressure sodium, and even fluorescent lighting options. This means you may be able to finally put away that expensive air conditioner or turn off a few fans since room temperature has been shown to decrease on average among gardeners who invest in LED panels.
