Replacing incandescent bulbs with CFL bulbs


A quick question for the experts out there:

I have a light fixture that warns me to use a 60W Type A19 (incandescent) bulb MAX. I would like to replace it with a CFL bulb. Can I use a 100W equivalent CFL bulb that only uses 23W? Or should I stick with the 60W equivalent CFL bulb that only uses 13W?

Basically, I'm wondering if the warning is based on wattage, or is it based on something else, like the temperature of the bulb.

I would love to use the 100W CFL bulb if I can - the 60W CFL bulb seems too dark...

Thanks!

Those limitations have to do with the amount of anticipated heat the bulbs will produce, not the light output.

You should be able to use any bulb up to 60 watts, as long as it will physically fit in the fixture. 23 watts is less than the 60 watt max.

With CFL I have increased the wattages in a lot of places
Where I used to have 60w I now have 75w CFL equiv
Limitation based on actual wattage...not "equiv to"

You go by the real wattage in these situations, not the fake equivalent light output wattage.

In addition to what has been said above, there is another aspect of this situation that needs to be considered. Many times a fixture is rated at a lower wattage (such as 60w) because the heat can't escape very well. In this situation, the heat created by the higher output CFL will not be able to escape. Altho this is not an issue with the fixture, it could be with the CFL itself, which doesn't get along too well with heat.

In the end this might lead to a much shorter life of the CFL.

Let me add a detail or duex.,

With CFL lamps some are not rated with dimmers or timers so check that out as well.

Some CFL are NOT rated to work in recessed luminaires { the heat will useally kill the electroniques quick }

For open luminaires all you have to follow the max wattage listed with real wattage not inflated wattage so you can put in larger CFL lamp as long it do not go over the wattage limit.

I know and I did see couple peoples stuck in monster 42 watters yeah big one { they are almost equal to 300 watters }

and that rated for 60 watts socket no issue AFAIK.

Merci.
Marc
