The standard plastic ones can not take sustained heat). Note: If you have 'can lights' and your house had attic insulation added after (retrofitted) construction, make sure the insulation DOES NOT cover the 'cans', the fixture can overheat
In the latter, There are Dimmers, and then there are Cheap dimmers to contend with, on top of special bulb electronic requirements to actually allow dimming |
I knew dimmers were a problem, so the ones we tried to replace didn't have dimmers but they were recessed. I can't remember if it was summer or not though, and the attic heat wouldn't be a problem in winter. I don't think insulation was added after construction, but since we didn't buy new I can't be sure. We also had our outdoor flood lights fail very quickly as well.
We went through two different brands for the kitchen replacements. The first only had about 10% to 20% of normal brightness when they were turned on. They didn't even start to increase brightness until nearly two minutes passed. Full brightness was after three minutes. The next ones were at full brightness after a few seconds, but they burned out after a few months.
