Some Globe-style CFLs are sucky.
As you know from reading my blog, I'm a fan of not throwing away my hard-earned cash. So it was obvious for me to replace my incandescent bulbs with much more efficient CFL bulbs. My conversion saved me quite a bit of money, but there was one trouble-spot: the CFL globes I installed in the bathroom.
I have one of those old-fashioned bar fixtures in the bathroom, designed for a set of three exposed globe-style bulbs, and so only globe style bulbs would look right in the fixture. I use my bathroom quite a bit, and the fixture with incandescent bulbs would normally require 180 watts to power (3 bulbs @ 60 watts each). Replacing them with CFLs seemed like an easy target for reducing electricity costs. "No problem!" I thought, since globe CFLs are readily available in retail stores.
I bought a set of three 14 Watt "Commercial Electric" globe CFLs from Home Depot (I think). Sadly, they had a long startup time - much like the CFL bulbs of yesteryear. I would go into the bathroom, flip on the switch, and wait in the dim light for a minute or more. It all came to a head when guests arrived - they complained that the bathroom lights weren't working. I told them to "hold it" for another minute while the bulbs warmed up. Embarrassing. Soon after, one of those globes failed - my one and only CFL failure.
I considered swapping out the fixture for a more modern one (that doesn't use all the tacky globe bulbs), but since I live in an apartment and don't want to make investments on my landlord's behalf, I decided to stick with the old-fashioned fixture.
I went back to the store (Lowe's?) and bought a set of three 9 watt Sylvania globe CFLs. I figured that a brand like Sylvania would operate more to my satisfaction, but I was wrong. The Sylvania globes were even slower in terms of startup. As a fix, I ended up swapping out the center CFL with a 25-watt incandescent globe in order to provide enough light at startup, and then after a minute or so the Sylvania globes would catch up and surpass the brightness of the 25 watter. Finally, my bathroom lighting was adequate, with two crusty CFL globes and one incandescent globe.
It all came to an end this week, when the incandecent blew out after a pitiful 3 months of use. So I went back to the store to buy a replacement. I found a GE CFL globe at Target, rated at 15 watts. I decided to give it a try, and plunked down $6 for the bulb (versus $2 for a short-life incandecent globe).
I placed the GE globe in the middle position of the fixture, again to give suitable light while the slow Sylvanias warm up. And to my glee, the GE gets bright very quickly. It takes less than a second for it to fire up, and almost immediately delivers full brightness. And that will make my bathroom experience all that much better, with a total consumption of about 33 watts - a reduction of almost 150 watts.
I could replace the two remaining Sylvania globes with GE globes, but now that I have plenty of light, I'll keep my bathroom lighting in its current configuration.
Conclusion and Recommendation
If you're buying globe-style CFLs, I recommend that you try the GE globes. I haven't had good luck with the other globe-style CFLs I've tried.
Other than globes, I've had great luck with CFLs. I haven't had a single issue with a "twist" or capsule CFLs, regardless of brand.
