[Magic]

The earliest iterations of LED grow lights were weak products of just 10 to 20W. However, these days products of 100W or more have appeared, which can successfully challenge the efficacy of older incandescent and HID lights of much higher wattage in terms of luminosity, while saving the user valuable money. This means that grow lights of the LED variety are now applicable in a wide range of indoor horticultural setups, instead of being limited to just the smaller ones. Furthermore, though LEDs with higher wattage produce more heat, the rise is insignificant compared to the rise in heat output noted in case of HIDs.

Good point
