KOR F13T5/CW T5 Fluorescent Tubes, 13W, 4100K Cool White, 6-Pack | 21-inch Length with 900 Lumens and Up to 15,000 Hours, 2 Pins at Each End for Under-cabinet, Under-counter and RV Lights.

These are my "go to" replacement fluorescent bulbs for my kitchen undercounter fixtures. I have five in my kitchen and I'm in a townhouse so my kitchen is pretty dark. We burn these almost continuously and they last for months and months.

Just as advertised..very satisfied

Tested all of them and working very good. I will buy again if I needed in the future.

It's a fair price. The bulbs are very bright. They are packaged well and each bulb has its own protective cardboard sleeve. I installed three shortly after they arrived. One lasted about two weeks! Yes, it died after two weeks and it wasn't used that much! After inspecting the bulb, it had dark black internally on one end of the bulb. Maybe I got a defective one because the other bulbs that I installed are still going and are used more frequently than the one bulb that died after two week.

After a few years of rummaging around in my pantry looking for extra virgin olive oil I realized lights go in there. I stood on a step stool and took two long bulbs out then found the replacements on Amazon. For the low, low price of $23 for six. And they work. Now I need to order all those nifty organizer things to make my newly bright pantry look instagram perfect. And I also need a dustpan and broom to sweep up the glass because my boys mistook the burned out bulbs for light sabers. I shoulda seen that coming.

love the daylight in my laundry room

Love the Warm White color and the bulbs are working great.

Update: I purchased these bulbs, due to the price and description, as replacements for over-the-counter lighting in my kitchen. I had previously purchased a different manufacturer's 2-pack on Amazon and had enjoyed more than 3 years of service from those two bulbs. I received this 6-pack of bulbs on November 5th, 2019. I found that these bulbs were not very reliable, as they failed after a very short time. I reported the failures in this forum as I progressed through the box. Today (February 16, 2020) the 6th and final bulb in the pack failed. Basic math reveals that each bulb lasted, on average, 17 days. The picture shows one of the failed bulbs at the bottom, with a fresh bulb (which later failed) above. You can see the blackened end of the failed tube. This is a completely unsatisfactory service life for a bulb under ANY circumstance, much less a 2 to 3 times per day activation of the ballast (each day) lighting my kitchen counter. The light from the bulb is fine and the brightness appropriate. Unfortunately, replacing a typical "residential use" of this bulb less than every three weeks makes this an expensive proposition, regardless of the favorable per unit price associated with the purchase. Because of the extremely poor service life, I cannot recommend this bulb under any circumstance.

Kitchen strip lights They work great and give very good lighting in an otherwise darker area of the kitchen.

the first shipment arrived with all bulbs damaged. What I liked was the quick response and replacement once I returned the damaged goods.

The packaging as not very safe and adequate for this kind of content.

These bulbs were just what we needed for our under counter kitchen lighting. The best price I have found!

The bulb emits a white light unlike the yellow tinge of a true daylight bulb.
