Building Custom Desk Lamp - Need Help

In my kitchen we have a recessed can above the sink (non halogen kind) I have yet to change a bulb in this light. I use to have 2 halogen track lights with 3 halogen bulbs per track that was burning out bulbs every 2-3 weeks if not sooner at times. We decided to change the light fixtures out for a standard flush. mount dome light with 2 energy saver bulbs and a pendant light above table with 1 energy saver bulb. we had the bulb blow in the pendant light within a couple hours and one of the bulbs in the flush mount blew in 2 days. Im very confused these are the only fixtures giving us issues and my husband instahled all new fixtures in the rest of our house that have yet to need a bulb changed and are going on a year old so im sure he wired them correctly. we have the correct bulbs in the fixtures as well. our dining room and entry way are also on same breaker and these as well as my kitchen recessed and have given us no grief. We live in a one story built in 1997. Any ideas?

Hello! In my bedroom, I have five recessed lights. One out of the five fixtures is actually working. We have tried different bulbs but not had any luck there. We tested one of the fixtures, and it is not showing any voltage. All four went out the same day. Any suggestions? Best, Derek
