Review: Great light-plants thrive-lasts long time - This is my second tube of lights. I have used them for years now and my plants thrive and grow quite tall. I have a variety of plants under this light: a couple of pomegranate bushes that bloom every year, an 8’ cactus that continues to put out new sections, multiple aloe vera with thick leaves, etc. They fit my light perfectly and last a long time. I recommend these for indoor plants.
Review: Great replacement - So much brighter! I had to replace 3 bulbs that weren't holding up anymore. Installed and WOW really made a difference. I only have one of the older bulbs and you can see how much brighter these bulbs are along side it. I will update my review to show how long these bulbs last and how bright they will be in the months to come. Two years from purchase and only two bulbs are holding up, not bad for 24hrs x 730 days, 17520 hrs and I’m sure they would last even longer if I use a timer for a few hours of off time.

### ⭐⭐⭐⭐⭐ Great light-plants thrive-lasts long time

### ⭐⭐⭐⭐⭐ Great replacement

### ⭐ Missing and Broken Bulbs. Aquatic Life is Higher Quality.
*by A***R on March 3, 2017*

UPDATE (September, 2017): Both of the Vivosun bulbs that I actually received in working order have completely stopped working. Not just dim, but dark. They didn't even last 6 months. I have had them on 14-16 hours a day over the summer, less in the winter. Stay away. I strongly recommend you spend a little more for the Aquatic Life Hydroponic Bulbs, 54-Watt T5 HO 6,500K Cool White Grow (4-Pack) Made in Germany . Barring one instance of shipping damage, the Aquatic Life bulbs arrived in good shape and are still going strong after 6 months. They are also brighter and have a more blue light. (All the bulbs are in the same fixture, by the way.) ORIGINAL REVIEW (March, 2017): The bulbs were packaged in a strong cardboard tube that seemed to have survived shipping. There were five paper sleeves that should each have had a bulb but only 2 bulbs! There were shards of what seemed like one more bulb that was broken. Where were the other two? Perhaps in dust at the bottom--I did not want to dig through the shards--but it appeared that only 3 were shipped. The two that arrived seem to be in good working order and much brighter than the 1-year old bulbs they replaced. And receiving two out of five in working order is an improvement: I ordered four more expensive, special spectrum bulbs at the same time all all arrived broken Aquatic Life Hydroponic Bulbs, 54-Watt T5 HO 6,500K Cool White Grow (4-Pack) Made in Germany (but at least there were clearly 4 bulbs shipped). UPDATE 3/26/17: I reordered the Aquatic Life bulbs and all arrived intact. They were actually much better packaged than the VIVISUN bulbs They were packaged by Aquatic Life, not Amazon, and it was clear that the damage in my first order of Aquatic Life bulbs was due to rough handling by UPS. In contrast, the VIVOSUN bulbs were poorly packaged by Amazon. Once installed, the Aquatic Life bulbs were clearly much brighter and bluer than the VIVOSUN bulbs--even though both are supposed to be 6500K. The Aquatic Life bulbs are clearly higher quality--worth the extra expense.
