Rated 4 out of 5 by Stapes Very comparable to the Hortilux super HPS
I have bought many bulbs over the last six years. I like these for the price point. They are very similar in specs to the 1000 watt Hortilux and are better quality than the Plant Max bulbs, which seem to burn out quickly. I would recommend these to anyone on a budget.

Rated 5 out of 5 by bent good alternative to the pricy ones
When you're in the 140k lum range, you don't need an extra 5k for another $70. Save your $ and get these

With the prices for the majority of the competitors being 2,3, or 4 times the price of these, it's a huge money saver for very little if any notice in performance. I will right in again and edit this review when I've used these for a longer period of time. So far so good thou!
