    • Purchased lots of t5 in 20 years and these suck
Size: 2 Feet
Just do yourself a favor and don't make price your biggest concern. These bulbs drop in brightness within the first 6 months and then they start burning out like crazy. I purchased a package of these in February and have used them 18 hours a day until January 2027 so about 10 months. The brightness had dropped by almost half at the 6-month mark as measured with a light meter. only one of them are still working In January 26th. They burn out prematurely as normal t5 fluorescents last several years out of the box. They sell a lot of them apparently because they show up at the top of the search results and they have a competitive price. Unfortunately they suck and I've been buying these type bulbs for over 20 years. ... show more

The closest yet to the real sun. Yet, all baby plants go outside on the first sunny day, and I bring them in to warm their feet at night. The Grow lights give me a six-week jump start on the garden.

    • Missing and Broken Bulbs. Aquatic Life is Higher Quality.
Size: 4 Feet
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. ... show more
