LED bulbs in old fixtures

Our old ceiling mount light in the laundry room says a 75w is the max bulb. How does that figure translate to the new LED bulbs? Do we have to stick with no brighter than a 75w equivalent?

You can use any size LED replacement.
A 100w LED equivalent bulb would be bright and only use/generate 15w of heat.

Thanks! The old bulb is dim like a candle so we wanted to upgrade.

We have this discussion often here: The wattage equivalent of a CFL or LED is a measure of brightness, The power consumption limit on the fixture applies to the actual wattage of the bulb, which is considerably less for CFLs and LEDs,

It means you use the actual wattage of the LED not the equivalent. The wattage limitation is in relation to heat. Equivalent wattage doesn't make heat only real wattage makes heat.

The new LED bulbs in the store are in packages labeled with something like:
Equal to XXX watt standard bulb, uses only YYY watts.

For your fixture rated 75 watts you can choose any new LED or CFL bulb using less than (or equal to) YYY watts.
Because you are complaining that the old bulb is dim as a candle, you should choose a new LED or CFL equal to a "standard" bulb with wattage somewhat greater than XXX..
