    • Great product, delivery exceeded expectations
Size: 4 Feet
This is a challenging order to fill properly, as it is extremely fragile and requires a lot of attention when packing. Everything about this delivery, exceeded my expectations. Great product, excellent pricing, and delivered 100% intact Thank you Amazon

Love these lights for growing my seedlings and my plants. It produces adequate light. Easy to switch out when needed. I use these in a greenhouse and my back porch.

    • Died out after two months in my Aquarium Wavepoint light system.
Size: 4 Feet
They were great at the start, I bought them back at the end of June for my aquarium Wavepoint light system to grow aquarium plants, and today at the start of September two of them died and the other two are faded out. They barely lasted 2 months. I don't know why, maybe they didn't like my aquarium light system, but they did not last. I will not buy these again ... show more

    • Tight fit, but works great!

The VIVOSUN T5 Grow Light Bulbs fit my existing Ferry-Morse Indoor Grow Light Fixture; however, it was a bit difficult to get the new bulb installed. The new bulb work great!

1 year later, 4 out of 5 bulbs are working. They're timed for 14 hours a day so that's 5110 hours per bulb and only 1 failed. Some other suppliers I bought from....all the bulbs have failed within 18 months. I grow herbs and these work great!

    • 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
