Led grow lights can speed up your plant's vegetative processes and boost yields and resin content and terpenes, while saving you over 50% on your energy bill. LEDs can deliver more PAR per watt than traditional grow lighting.
LED manufacturers have developed specialized lenses to point light directly to the plants and increase penetration, resulting in bigger yields for the same amount of light compared to older models. There are also many different form factors, with everything from the casing to the size of the diodes varying from model to model.
The standard panel LEDs have small to medium wattage diodes and the lamps tend to be more compact. Most LED grow lights available today are in this style. They are sort of halfway between a Quantum Board and a COB Style light, with a mix of features from both.
