Wanna know what the best 1000W HPS grow bulb is on the market?
3 HPS grow light bulbs
You walk into your local hydroponic store or browse the internet looking for the best HPS grow bulb at the right price range... but then you get stuck. There are so many brands claiming they're the best dest and brightest with the best lumens and high PAR, etc., etc.-- which makes it difficult picking the best HPS light bulb that can help you produce your desired yields. Not only that, but the prices between all the different bulb manufacturers differ and it's tough figuring if the money you'd spend is going towards a bulb that claims what it does. Well, GrowAce has put your question to rest. We did a comparison test on 6 of the biggest HPS grow light bulb brands and pit them against each other. We set up parameters to make it as objective as possible and the results were surprising:

Testing the Best 1000w Single Ended HPS Bulbs

We asked our Instagram and Facebook followers what their favorite bulbs were, and combined with the highest-selling grow light bulbs on the market and we tested the following 1000w HPS bulbs: Using the same grow light ballast, reflective grow tent, and PAR meter, we tested each bulb for its total light intensity and here's what we found:
Best grow light bulb
To be thorough, we measured the PAR readings from three different heights, 15 inches, 27 inches, and 51 inches. Here are the readings from the highest par reading to the least to show you how much power these bulbs put out:

We also created a comparison graph on the average PAR reading in the footprint we measured.

And there you have it, the results for the top 6 popular grow bulbs to help you complete your best grow light system. As expected, time and time again that Hortilux outperformed the other 5 HPS bulbs, but here are a couple of other discoveries we made during this review:
    • While Eye Hortilux outperformed Yield Lab, it was Yield Lab that came out to be the best value
    • Yield Lab 1000w bulbs outperformed the 4 remaining bulbs and cost $12-70 less than them, too
  • The best, safest packaging goes to the Digilux bulb. While it did not perform as well as the rest, it's packaging was hands-down the best we've seen in a while
So with all that said, which is the best bulb? In terms of the highest light output, the winner is Eye Hortilux. In the battle for the best value (which we believe is the better choice of the two) you've got to go with Yield Lab, hands down. The next time you're out buying an HPS grow bulb for your fruits or flowers, remember this chart and ask yourself... Am I getting the best bulb for the price?



Appreciate the recommendation. Let me try it out can not wait to give my feedback.

“Hello William.

That is a great question. Since the HPS bulbs are sensitive you can tell by any black spotting on the bulb or a blue spotting. However, we do advise when grabbing an HPS bulb to be sure to put on a pair of gloves due to the fact that the HPS bulbs are delicate. All our HPS bulbs are shipped as a new bulb and will show no signs and if any issue that this does occur we will be more than happy to take care of you."


I know you used the same reflector. But it would be great to see this same test done, except for reflectors too. I can’t really apply this information to my particular setup because there are so many different reflectors. I would have to have the reflector you tested with for this to really mean anything for my particular setup. So, there, requested :) Same test, except Try each reflector with each bulb. I know its a lot of data to collect, but that would be very impressive. This is impressive too. Nicely done!
