Failed (melted) LED 2D retrofit lamp.

It was put into a fitting rated for a higher power lamp, and as it relies on the existing ballast to limit the current, it caused the lamp to overheat with the higher current than it was designed for.

There's a huge range of pocket scopes now. It's worth looking for reviews that show them in use in similar situations to your intended use.

I have been trying to save up to buy an oscilloscope for a few years now, but when I finally found one that I could afford it ended up being in-op and I have no idea how to fix it. Besides being in working shape, what should I look at as a minimum requirement in an old affordable scope? I hate the idea of finally being able to buy another one and find that it doesn't do what I need. I have been fooling around with old radios, but also want a scope that will help with a larger range of newer circuits.
