Hi,



I am a little confused. If someone with electrical experience can answer, I

would appreciate it.



I have a ceiling light fixture that has space for two bulbs. It states that

the wattage limit is 60W per bulb. Now with everyone using Halogen bulbs,

can I place 2x 53W Halogen Bulbs - which produce the same lumens as a 75W

incandescent bulb, or do I need to ensure that the lumen output does not

exceed that of the 60W incandescent, which would mean a 43W Halogen bulb?



I hope the question makes sense. I know that halogens produce more heat than

incandescent, so I am not sure what the Wattage limit is about - is the the

heat that is produced, or is it about the energy that is drawn?



I would appreciate a response - dont want to take any risks, but would love

to maximise the lumen output.



Please note, only Halogen or Incandescent bulbs can be used in this specific

fitting.



Thank you in advance.



This one is straightforward. The 60 watt x 2 limit is based upon heat via a

UL test based upon standard UL-1598. The lumen output of the lamps doesn't

matter.



To the best of my knowledge, halogen bubs run hotter than regular

incandescents.

Halogen are slightly more efficient than tungsten so watt for watt they should produce slightly less waste heat.
