Easy installation, just screw in clockwise and press switch. Lights up magically! OK, seriously. These were exactly the bulbs I needed to keep things from burning in the oven. Can't comment on longevity as I just put it in the oven. As for the presentation, hmm. Well they were in the package so I thought the presentation was great. I would buy them again but I bought six a pack so it should be a while.
