iPower 400 Watt HPS Grow Light Bulb

iPower grow bulbs, like this 400 watt HPS lamp, cost less than other high-quality bulbs, but they perform at the same (or a higher) level. This bulb gives you 55,000 lumen of output and has a lifespan of 24,000 hours. You will not find many bulbs that can match that, even at double or triple the price.

You can also get two of these bulbs for a bit less in a 2-pack.
