There is no doubt that LED light systems have introduced a number of benefits to the industry, but there are still things to consider when making this decision. HID bulbs try to replicate the energy created by the sun in a much truer way, and therefore offer plants a more natural, full-spectrum simulated sunlight, whereas LED lights try to digitally deliver parts of that light spectrum. It really comes down to quality. High end LED lights bring about a spectrum that is much closer to HID bulbs. LED lighting can give you the same desired results while using less energy and creating less heat, but avoid low quality circular LED lights, because they do not perform as well as HID bulbs. JUMP TO LED LIGHTING
