I've got a fluorescent lamp on my desk which I've been using for about 3 months. Before that it had spent at least 5 years or so in the garage. It's been working fine (a slight delay when starting up, but I'm pretty sure that's normal), however recently I've noticed that when it starts up it makes a fairly loud crackling noise as the light flickers on (with each flicker of the light it makes a noise). Is this normal?
The reason I'm asking is that it's right next to my desktop, so I won't be too impressed if it blows up or something. On the other hand, I don't want to replace something that's not broken.
Does anyone have any experience about this or advice?
