"Can I use X watt CFL/LED/Halogen bulbs in a Y rated fixture?" seems to be a fairly popular question lately. Do we currently have a good answer for this question, that we can close new questions as a duplicate of?
Can I use a 60 watt Halogen bulb instead of a 100 watt incandescent bulb?
Can I put 42W CFL bulbs into a fixture marked as “R20 Halogen bulbs up to 50W max”?
Can I use an 11 watt bulb in a desk lamp that says “CFL max 9 watts”?
Can I use a 23 W CFL in a fixture that's rated for a 60 W incandescent?
