Is there a 40 watt CFL bulb?

Answer 1

Yes. You can always use a light that uses LESS than the rated capacity of the fixture, just don't use a bulb that is rated at MORE than the rated capacity.

The 13 Watt CFL uses LESS than the rated 40 Watts... so it's safe. .............

Unless the light fixture is connected to a dimmer. Most florescent bulbs don't work with most dimmers. Look for a note on the dimmer like; " suitable for florescent lights" or on the bulb "suitable for use on dimmers"

Answer 2

You are likely looking for a CFL that is equivalent to a 40 watt incandescent bulb. You want the lumens to be equivalent. The wattage required for the CFL will be quite a bit less than for the incandescent.

Answer 3

If the bulb will physically fit and is within the wattage rating for the particular fixture, the answer is yes, however, bear in mind that appliance bulbs are more rugged than regular ones, so the trade off is these bulbs draw more current and therefore will cost you more to run.

There is no reason why you can not use a 40 watt bulb in a lamp. A lamp that is rated at 40 watts, whether it is an appliance bulb or an ordinary everyday use lamp will both draw the same current. The have to because of of the following equation Amps = Watts/Volts. The only difference between the two lamps is that the appliance lamp is built for more rugged use. This is done in manufacturing by adding more filament supports to hold the tungsten filament from movement if the bulb gets jarred in its operation. Where a normal bulb may have two filament supports an appliance or rough service bulb may have from three to five filament supports.

Answer 4

Yes, there are 40 watt CFL (compact fluorescent lamp) bulbs available. CFL bulbs come in a range of wattages, including 40 watts. They are energy-efficient alternatives to traditional incandescent bulbs.
