Like these:
Trying to figure out if I'm doing something wrong or these things are just crap. I can rarely get more than a few hours at a time out of the bulbs in these things before they go. Normally find the ceramic (?) bits at the end of the bulbs have cracked off and/or the glass at the end.
I think the instructions typically say keep 1m clear all around, but a) I sometimes do this but still have the bulbs go pretty quickly, and b) often I can't get 1m all around.
Is this just the way these things are, and are there any practical ways to improve bulb longevity? I tend to buy cheap-ass bulbs, but that's because my expectation is that they won't last long - perhaps it's circular!
Maybe LED versions are better in this day and age - any recommendations?
