My table lamps were over 20 years old, dated and the shades had faded and the plastic was disintegrating. I looked for replacements awhile ago but was looking for something with a tri-light switch since it is nice to be set them at different brightness levels. Tri-light incandescant bulbs don’t seem to last and are also available in CFL versions.
I found some more modern lamps at the Target liquidation sale and snapped them up even though they weren’t tri-lights. I got LED bulbs for them since they tend to be on all evening. I was going to get a slide dimmer but end up finding touch operated dimmers that operate with metal lamps. I found these at Princess Auto though Canadian Tire has them as well for quite a bit more.
