Question: I need a T4 circline bulb.  Is this it?
Document: Works great. Fit like it was the original bulb. I would recommend to anyone who needs this type of bulb.
My wife's favorite work light has this vary hard to find bulb. I bought two. They came on time and worked like they should.
Had my fingers crossed and I got lucky. On my first try I got bulb that fits and works. A little pricey though.
after having 3 inexpensive  bulbs burn up within weeks, I finally thought I would try this bulb before putting the entire lamp in the trash can. after 3 months, bulb is bright, and still working great.
It did not fit the magnifier so I have not been able to use it. I wish I could return it.
Bought this as a replacement bulb for my magnifier craft lamp. It's lasted a long time - longer than the original so far.
The replacement bulb worked great in the magnifier lamp that is used for inspecting label graphics in our quality assurance department.
I ordered this fluorescent tube from Amazon because at the brick and mortar store where I bought the lamp, it would have taken over a week to get the replacement tube. Same product; works as expected.
We were happy to find natual light bulbs for our clip lights that we use on our bird cages. We can control breeding patterns this way. This is a different use for magnifying clip lights and much cheaper that free standing lamps. The bulbs last a very long time.
Answer: yes
