iPower 400 Watt Metal Halide Grow Light Bulb

iPower grow bulbs, like this 400 watt metal halide (MH) lamp, cost less than other high-quality bulbs, but they perform at the same (or a higher) level. This bulb gives you 36,000 lumen of output and has a lifespan of 12,000 hours. You will not find many bulbs that can match that, even at double or triple the price.
