Utilitech G25 5000K CFL

I really hope I don't regret buying these. I just swapped out two Feit Electric and two GE G25 globe CFLs of 2700K that are about 8 years old that still worked fine (but have dimmed somewhat) - they had rapid-start triple-tube internals. These are, of course, instant-start spirals with amalgams (so start very dimly), but I really wanted 5000K lamps in my windowless bathroom (hey, it's cheaper than building in a skylight) to match the other bathroom that has 32w T8 SPX50's. Well, these have lower CRI than the linears but they still do look quite nice. Will they last 10 years, though? We'll see! (you gotta love the slogan, "Grounded in Quality").
