Thanks to recent advances in technology, screwing in a light bulb is a talent I no longer posses.
Consider this set up in the first picture.
Those are ordinary switches at location 1,2,3,4. Switch 2 is to connect to an LED light (3 Dimmable bulbs , each 6W, ST19, GE, replacement for 60W, see details in picture 3 and 4, I got these from a big box store and it turned out online they are half price!).
I want to replace switch 2 with a dimmer. Is this safe and doable? Are other modifications needed by code? What is the generic name of product I need to replace switch 1+2? The current switch-plate on the outside is 4.5" by 4.5". The interior of wallbox is about 3 3/4 wide and 2 7/8 tall.
Some issues came up. Apparently dimming LED lights is a complicated issue. You have to watch out for compatibility. GE website does not list a dimmer for this dimmable bulb of theirs, while it lists it for hundreds of other bulbs! And Lutron Website, which makes dimmers, does not recognize this bulb either! So I am wondering if I should return the bulbs?
