I have two coach lights on my porch that I'd like to put on a dimmer to
reduce their brightness. It's a small porch and even with 40w bulbs it is
pretty bright. Problem is we generally turn the lights on at dusk and off
at dawn and I was wondering what the life expectancy and risks might be of
using a dimmer. I know dimmers generate some heat.

I'd need to use a 3 way dimmer. The lights are controlled in the family
room and the laundry room, both switch locations are ganged, 3 in the family
room and 2 in the laundry.

Anyone ever do this?

Thanks for you input!

Mark

No risk at all. Install a three way dimmer at either location, or if you
really don't need the light, use smaller wattage lamps

Thanks!

I tried 20w, but the bulbs were expensive, a little small in the fixture,
and didn't last very long. It would also be nice to have the option to turn
them up when we'd like the extra light.

How about 25 watt "T10" ("refrigerator/showcase") ones?

At full power, a "Big 3" name brand one of those produces close to 230
lumens with life expectancy of 500 or 1,000 hours, brighter than a 25 watt
A19 designed to last 2500 hours though dimmer thjan a 40 watt one.

At 10 watts, a 25 watt 120V tubular produces about 25-30 lumens of
light, brighter than a 4-watt but a bit dimmer than a 7-watt incandescent
120V nightlight bulb. A 40 watt A19 to produce that amount of light
requires about 15-16 watts.

if you going to use a regular incandescent put the dimmer AFTER the 3
way switches in the line feeding the lamp.

this way you dont have to disturb the 3 way switches they are easy to
muck up:( and persumably you wouldnt be changing the lamp britness
often so the dimmer can go in a easy place to install.

lamp life will skyrocket.

although energy wise your probably better off with CF
