Thanks for the replies guys. I spent hours today reading and researhing this because I have an unhappy customer who doesn't want to pay for the new dimmer or bulbs that have failed on a job with very low use on the installation, maybe 8hrs use.
Trumpy...I used a 1000watt Lutron dimmer on 3 outside bullet style double flood lights with G8 base 120volt 100watt halogen capsule bi-pin style bulbs.
I found some light bulb info in another thread here on this site...
http://members.misty.com/don/bulb1.html#wbsI also called Philips technical assistance who said the bulb failure would never cause a dimmer to blow out. They said it must have been a power surge/spike or some problem with the dimmer.
I called Lutron technical assistance who said that it is possible that bulb failure in some instances can blow the dimmer.
Both companies offered replacements and Philips said to send the failed bulbs in so they could have a look.
Greg...I have 3 failed bulbs from the job and 1 bulb has evidence of a violent condition when it failed. There are burn marks on the glass inside the bulb and the filament supports have broken apart completely.
I suspect this failed bulb caused the dimmer failure.
