Below is more on this lot of 5 Grow lights: Below is more on this light: - 315w Ceramic Discharge Metal Halide grow light kit delivers a light spectrum that's much closer to natural sunlight than typical high intensity discharge (HID) systems. A higher temperature creating light much closer to the sun’s. Being able to operate more efficiently at higher temperatures means a boost in performance, Coverage area is 4ft*4ft,that means bigger harvest and less cost - The lamp is optimized for the bloom phase with enhanced reds, but, because it's full-spectrum, it will produce the goods in both vegetable and flower – expect to see increased growth rates, tighter internodes, an improvement in overall vigor and an increase in final weight. - Size:18" Long x 9.5" Wide x 10" High,Input 16AWG/3C SJTW 105℃ 300V Cord, 110V, 5-15P Plug , L=16FT - Degradation time: Standard MH bulbs have a lifetime of around 10,000 Hours.
