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’s so many brands claiming they’re the baddest and brightest with the best lumens and high PAR, etc., etc.– which makes it difficult picking the best HPS grow 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 actually 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 setup parameters to make it as objective as possible and the results were surprising:
Testing the Best 1000w Single Ended HPS Bulbs
- Eye Hortilux Super HPS
- Digilux HPS
- Sunmaster Yellow Blossom HPS
- Yield Lab High Output HPS
- Ushio Hilux Gro
- Maxlume HPS
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:
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 actually 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 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?
