This high power 90-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. It saves 80% to 90% in energy consumption compared to fluorescent tubes, HPS or MHS 95% lights of LEDs can be absorbed by plants, but only 10% by HPS or MHS Reduce grow room temperature but 15 degrees compare to HPS or MHS high power LED estimate to last 50, 000 hours. High power LED has the light decay about 5%, Nearly no maintaining. Wide angle projection insures uniform leaf coverage. The design of this new all in one Full Spectrum grow light allows maximum level photosynthesis food production, growth and flowering all in one. It is the new Full Spectrum system providing maximum plant health, beauty and productivity.
