Bang for buck CFL bulbs,
Verified Purchase(What's this?)
This review is from: GE 13-Watt Energy SmartTM - 8 Pack - 60 watt replacement (Tools & Home Improvement)
The package came nicely packed in bubble wrap, and no bulbs were broken. Unlike most CFL spiral bulbs I've used, these have a narrower base and are closer to incandescent bulb bases.
Compared to older CFL bulbs I have installed, these light up instantly. While the box says its not at final brightness until its allowed to warm up, its not visibly brighter even after 1/2 hour. Checking it with a lux meter, it does ~800 lux/1 meter, that's ~ lumen expected.
A typical incandescent bulb lasts 1000-2000 hours, while the GE website and the box state it should last 9000-10000 hours. That's at least 5-10x longer. FWIW, left on 24/7, a year is about 8800 hours. I typically have most lights on for 3-6 hours, so worse case GE estimates it should last 9000 hrs/3 hr/day = 3000 days or 8.2 years at best, 4.1 at least.
Many of my house lights are X-10 switched with dimmer modules. Despite that, some of my CFL bulbs on the modules have lived a long time, it also makes my incandescent bulbs last long too. I will try to see how these bulbs do on the same sockets, with or without a dim level, and will report back. Over a month later, all is well.
The same type of bubs sold retail at Walmart cost $15, for 6 bulbs. Even if a few broke in transit, its far cheaper than retail. How cost effective it will be now depends on how long they last.
