How does this light compare with HID lighting performance? Not all light is created equally. And neither are LED lights! At least not as far as plants are concerned. Below is an accurate chart of light spectrum usage by plants. Light spectrums are measured in nanometers or nm. Chlorophyll production is made up of two parts, A and B. Maximum chlorophyll A production occurs at 662nm (for red) and 430nm (for blue), while maximum chlorophyll B production occurs at 642nm (for red) and 453nm (for blue). These are the peak points at which chlorophyll production is maximized, even just a few nm above or below these points will significantly reduce production. There are ideally 4 peaks of growth spectrum. Larger leaves lead to larger surface area for further absorption, etc, etc. But it is still... Less

This high power 600-watt has no ballasts to burn out like other plant lights. It runs at a warm temperature rather than very hot which is common with most other inefficient plant lights. This more controlled running temperature reduces the need to water so often and keeps rooms with plant lights from getting uncomfortably hot in the summer months requiring additional air conditioning. This state of the art LED grow light is extremely energy efficient, paying for itself many times over annually in electricity savings.
