Maybe you guys can help. I'm going nuts here!

I've been buying Duramax bulbs, Duramax br40 bulbs upc 046677139278, for the past 7 years and love them. I have about 15 of these bulbs in my house in recessed lighting fixtures in my ceiling. I buy some of these bulbs every year. I just went out to buy some more and noticed the packaging changed for the bulbs, no big deal I thought, as the UPC code was the same. But, when I got them home, these bulbs are slightly different and NO LONGER FIT in my ceiling recessed housings. The old bulbs, which I still have, have a chrome finish on the neck, whereas the new bulbs are all white on the neck. Eventhough the UPC is the same, the dfeinitely changed. The old bulbs were made in mexico, and the new packaged bulbs are made in china, and the necks of the bulbs are slightly different, and this change doesn't let them fit in my housings. I'd like to know why this bulb changed in physical size if the UPC is the same? Maybe phillips isn't aware of this and it's a defect? I really need bulbs that will fit and have been using these same bulbs for 7 years as I mentioned earlier, and I buy "duramax br40's" because they last long, but now don't fit.

Here is the 2 pack old packaging where the bulbs had chrome neck, and says 630 lumens, last 1 1/2 years:

New packaging, and says 625 lumens, last 2.3years:

Again, the new packing is the same UPC!! Here you will also see the old bulb, which has chrome neck, and you can see how the new bulb on the right has CHANGED. But again, same model number!
