Why shouldn't different types of light bulbs(i.e. incandescent, LED, cfl) be used in the same fixture?
I read this under the CAUTIONS & WARNINGS
section of the LED bulb packaging.
...Do not use in multi-bulb enclosed fixtures together with other bulb technologies (e.g. incandescent, halogen, CFL, etc.)...
I have followed this warning, but I would like to understand the reasoning behind it.
