Great

Works fine.
I like that I was able to find one of these bulbs. I don’t like that I should have checked and plugged the light back in before ordering a new bulb.

Great specialty bulb
This is a hard to find replacement tube, so it was nice to find it here. They aren't cheap, so if you don't already own a fixture that uses this unusual tube, don't buy one. If you already own one and need a replacement, this one is a good bet. The packaging is superb, unlike another reviewer suggested. I purchased to bulbs, which were in original, unopened packaging, rubber-banded back to back, and wrapped in sufficient bubble wrap to fill a 4x8x12 inch box. Bulbs are easy to install. Only downside, they are a little slow to warm up and brighten up. Once brightened up, they illuminate my undercounter space very well.

Excellent replacement of hard to find bulb. FYI: 10.5" end to end.
I spent 3 days trying to track this odd bulb down between the Home improvement stores, Wally world, and my local hardware store.. Even the store I bought the fixtures from (Loews) doesn't carry it. I had forgotten I bought the bulb here on Amazon once before (four years ago to be exact) Lo and behold they still have it. Not the cheapest solution, but those "1001 bulbs" websites that sell it for $2.00 also charge $15.00 for shipping, which is crazy. The price here was ok enough for something that's going to become harder to find in the future. Because it's such a weird size, there is currently no LED equivalent like the more popular 12' or 48" sizes.I made the crusade to rid my entire home of those horrible twisty CFL bulbs with more efficient (and safer..) LEDs as soon as they became affordable. However, my kitchen has 6 chained mini fluorescent fixtures under the cabinets. I'm going to be replacing those last remaining FLS with LED pucks, just not a project I have time for now. Mine are on at least 12 hours a day so fair enough value that I got 4 years from the last one. I'm happy! BTW: it's 10.5" end to end.

Glad Westek still provides this hard to find product
I purchased this T4 fluorescent Tube light from Westek on Amazon because my local Lowe's no longer carries it. I have several under cabinet light fixtures that require this specific size. I love that I can still get them from Westek, but these bulbs don't last very long. My first one lasted 3 months so hopefully my second one will last longer. I will give the product more stars if it does.

Perfect fit!
I was not able to find this bulb locally so I was glad that I found it through Amazon.com. It was just what I needed for my under cabinet light fixture. The description was detailed enough that I was pretty sure it was the correct bulb, and was pleased when it arrived and fit perfectly. It was packaged well and arrived in a timely manner. I will definitely order again, assuming the fixture outlasts the bulb!

They work fine but don't last long
They burn out way too quickly. These are either cheap Chinese junk or the fixtures they go in are, and are destroying them. A decent fluorescent bulb should last 5-10 years. These last 6 months to 2 years.

Was happy to be able to find this bulb for an old lighting fixture
When the bulb in my under-the-cabinet lighting fixture burned out after years of use, I wasn't sure I would be able to find a replacement bulb. After some unsuccessful searches, I was very happy to find that this vendor had the bulb I needed. I was a bit skeptical that a single light bulb would survive the bumps & bruises of shipping & delivery, but it came through with flying colors - perfectly unscathed and delivered quickly! Great experience!
