4 ft. T5 28-Watt Cool White (4100K) Linear Fluorescent ALTO Light Bulb is rated 1.3 out of 5 by 9.
Rated 1 out of 5 by from 3X the price, 1/10 the life comparied to commom size floresents. I installed a new fixture 5 months ago with 2 electronic ballasts powering 3 of these tubes. one tube died after 3 months, the other two died after 5 months. These tubes lights may last 20,000 hrs as the manufacturer claims if installed in the old school iron ballast fixtures, I don't know. But I do know they suffer sudden infant death syndrome (SIDS) if installed into a fixture with electronic ballasts. That aside, they are still 3 to four times the price of any other size tube light. Very dissatisfied.

Rated 1 out of 5 by from Did not last Long New home in laundry room. Light was wonderful while it lasted. This bulb lasted only 6 months. For the price very disappointed.

Rated 1 out of 5 by from 20,000 hours my foot Bought a new fixture less than a year ago. I didn't realize it required these small, over priced and hard to find bulbs. Two went bad already.

Rated 1 out of 5 by from 28 w 4ft t5 alto fluorescent bulb I wish I had read these reviews before I bought mine. What a piece of junk! Bulbs burned out 3 times this year. Cost me $70 first of year. Home Depot replaced free but I feel I'm wasting my time. The lumens are great but not worth the money and aggravation. Don't know what I'll get next, but not T5s!!

Rated 1 out of 5 by from Outstanding.... ....ly poor life. Three bulbs installed in a new fixture in a laundry room lasted less than a year with very little use. They failed to start intermittently which developed into a full consistent failure. For an eleven dollar bulb with a 20,000 hour rated life, this is appalling performance. The big box store with the gable logo has house brand bulbs for less than seven dollars.

Rated 1 out of 5 by from t5 junk It's thru they give fantastic light for what they are but they die fast . This 4f bulbs are pure JUNK I purchase 6 fixture and in 18 months I replace all of them (12) and now again Im down to one bulb in each . Out of 6 fixture 2 of them have to be replaced . ***DON't waist your money get the T8 *** I wish I can replace mine for T8

Rated 1 out of 5 by from 6 Months is "Long Life"? I purchased a fixture in October 2012 that took 3 of these bulbs. All 3 burned out together last week. At the price they get for these, if the exorbitant cost replacement bulbs I got perform like the originals, I'll be shipping them and the fixture to DoE with a poignant suggestion what to do with them. Fortunately, there are still some dependable fixtures still available.

Rated 1 out of 5 by from Product life expectancy extremely over-rated Professionally installed (2) fixtures containing 3 tubes each in June 2013. 4 of the 6 tubes have burned out in less than 100 hours of use.
