I ran power and new lights... couple questions

Yesterday I installed new pendant lights where there previously were no lights. I tapped into an existing outlet's power, added a junction box with a dimmer switch. Installed 3 ceiling junction boxes. On the new line, there are 3 pendant lights. All of my wiring and connections went smoothly. The pendant lights are rated for up to 60 watt bulb, which is what I used. The power was turned on and all 3 lights worked properly. Within about an hour, the middle light bulb burned out. When I removed it, it was a milky white color (these were clear bulbs). The other 2 bulb s continued to function normally. After replacing the bulb in the center light, shortly thereafter, the second bulb was burned out again. This time, the bulb is black. What is up? The 2 bulbs came from different packages. The other 2 lights have not burned out.

Another thing I noticed... the dimmer switch is a slide bar type. When you slide the bar all the way up, the light is on, fully. Slide it down, the lights are supposed to be off. There is no on/off switch. When I slide the bar all the way down, the bulbs do NOT go out completely. There is a very faint glow coming from each bulb. What going on here?

Could be bad bulbs. What is the wattage rating of the dimmer? How exactly did you wire it? Does power come in at the center bulb? Have you tried it with a regular switch?

That's a strange one. Try measuring the voltage at one of the fixtures or at the dimmer. As long as you're getting about 120v (112 - 126v) you're well within tolerance. There's nothing that the dimmer could be doing to increase the voltage.

Also, the dimmer should have an 'off' position, likely by sliding the dimmer down to its most dim, then pushing it a little further to click off. If there really isn't an off setting, are you sure it's a dimmer and not a fan control?

Last thing, are you using name-brand bulbs? Maybe, even though they were in different packages, they were likely from the same production run - who knows, maybe there was a problem with that run.

Any chance can you get the dimmer model number and manufacter if you can ??

i know most slide dimmer when you slide down some have to push a little to feel a click to turn it off.

hope you did not use the wrong type of dimmer.

as far for the bulb itself you should able screw in the bulb but not very hard just engough to get it light up sometime a bad batch can show up from time to time.
