3.0 out of 5 stars Annoyingly Needed Adjustments to Fit.
Reviewed in the United States on 7 March 2021
Once installed, they ended up brighter than the bulbs they replaced and work in my fixtures with ballasts.

The issue is that the pins are spaced about 1/16th of an inch further apart than the pins on the original bulbs. This can be seen in one of my pictures. Old bulb on the left.

It took some fiddling with a pair of pliers to get them to just the right spread to fit in my light fixtures. Fortunately these are basically led strips inside frosted glass tubes rather than vacuum tube glass, so they didn't implode or shatter in my hands while working on them. That said, taking a pair of pliers to these is not what I consider an ideal outcome for what should have been a quick five minute swap of bulbs.

Two stars deducted for the hassle and fear I was going to break brand new items.

I can easily picture less handy people simply returning these in frustration and I can't blame them for that.
