4-Pack 2 Foot (22.625") 6,400K Grow T5 Fluorescent Grow Light Bulbs - (4) F24T5HO Bulbs

all arrived in good working order shipper did great protecting in shipping

Good bang for your buck, does what it is supposed to do. Fit my fixture perfectly.

Used for cuttingsand seedlings in a two by two little grow tent.

On October 17, 2017 we ordered one 4-pack of these bulbs, which worked well burning 12 hours per day, 7 days a week, until they finally expired this past December after a little over 3 years of continuous use. We reordered the product on December 29, 2020, this time ordering two 4-packs. One of the eight bulbs was physically broken on one end, and the seller promptly replaced it.Four of those new bulbs lasted, burning 12 hours per day, 7 days a week, until last week - roughly 3 months, not 3 years. The remaining four bulbs from our second order are all showing at least an inch of blackness on one end, indicative of end of life.We will not be purchasing this product again.Update, April 15, 2021: the remaining four bulbs are now burned out.

When the bulbs burned out in my small plant light I had no idea where to get replacements. I couldn't find anything locally. These arrived in perfect condition, very well packaged, and they fired right up when I installed them.

Don't wait until the bulbs burn out. Once you see black appear on the ends its time to replace them. Les beneficial light is produced past this point.

Bulb fit and worked as expected. Package was very well wrapped for shipping.

I bought these bulbs to replace the bulbs in one of my T5 light fixtures that I use for grow lights. I usually look for 6500K bulbs, but these are pretty close and the plants seem to love them. They are much brighter than the old bulbs that had been used for over a year,, and I believe the price is very good for these bulbs.
