I’ve been hearing a lot of complaints about CFL bulbs lately. I’ve written about how to address premature CFL burnout before, but I guess it bears repeating. It’s a five-minute fix, usually, to get the bulbs to last a while. So here’s what to do if your CFL bulbs burn out quickly.
Odds are that if your CFL bulbs burn out early, so do incandescents, but we notice it more with bulbs that advertise a lifespan measured in years rather than months. If an incandescent burns out after 3 months instead of four, we don’t really notice.
Check this tab first
Inside the light socket, there’s a metal tab that engages the light bulb. Over time, this gets mashed down from tightening bulbs all the way. Reach in with a popsicle stick or something else non-conductive and bend that tab back up. It doesn’t have to be far. About 15-20 degrees usually does the trick.
Check your light switch
If that doesn’t fix it, chances are it’s the light switch. The internals of a light switch can corrode or get dirty over time, which hurts conductivity and shortens bulb life. Switches in rooms like kitchens and bathrooms are especially prone to corrosion or dirt. If your CFL bulbs burn out quickly even after you fix the tab in the socket, it’s probably the switch.
I have some tips for replacing a light switch at the end of this entry.
Not all bulbs are the same
The other possibility is the bulbs themselves–some brands do better than others. I did well with Ecosmart and Feit bulbs; I had mixed success with other brands prior to discovering those two. So when all else fails, try a different brand.
I bought my first CFLs in 2003 and was 99% CFL by 2005. I bought my last big package of CFLs in 2008. The CFL in my garage lasted from 2003 to 2017 and I replaced it to get 40% more efficiency and 50% more light, not because it had burned out. They have their detractors, but CFL bulbs really do save energy and money. I noticed a difference of about $10 a month in 2003-2004. And in 2011, when I had modern bulbs and did a few other things, my power usage dropped 19 percent.
The LEDs I’m buying are about 50% more efficient than the CFLs they replaced, so I wasn’t heartbroken when one burned out. I like LEDs better but if you have underlying issues that cause CFLs to burn out early, LEDs probably will too. Fix those issues before you switch to LEDs.
Energy savings from newer technology
If your CFL bulbs burn out quickly, it’s worth tracking down the problem and fixing it. You’ll save more money from that than you will from switching back to an older technology.
I would estimate high-efficiency bulbs have saved me at least $1,200 since I started using them in 2003. Not many people have that much money to just throw away. And that figure isn’t counting the replacement cost of the incandescents that would have burned out over that time. That’s probably double what I’ve spent on the more advanced replacements, since modern lighting lasts so much longer and I haven’t had to buy them in quantity for a very long time.
