LED bulb longevity report

Dave Farquhar Saving money , , , , , , , , ,

Now that I’ve had a couple of LED bulbs burn out, I can actually give an LED bulb longevity report.

I’ve been buying LED bulbs since 2010, and now I’ve lost three of them. It’s a little disappointing, but two of the bulbs were Philips 420240 bulbs, which are no longer on the market. The first 420240 failed completely within a couple of weeks of getting it, and I exchanged it for a Cree. The second 420240 lasted a shade over two years. Clearly the 420240 just wasn’t a very good bulb, and it accounted for my first LED bulb mortality.

My other failed bulb is one of the early 40W equivalents I bought at either Lowe’s or Home Depot in 2010 or early 2011. So I got about four years out of that one, which is better than Philips at least.

Enerlites HOSS: an occupancy sensor switch without ground

Dave Farquhar DIY, Saving money , , , ,

The Enerlites Top Greener HOSS is an occupancy sensor switch without ground wire requirements, and it’s pretty cheap too, at $12. A Lutron switch costs almost twice as much.

But the HOSS does come with some compromises. The HOSS does require a neutral (white) wire. But most switch boxes will have the whites in there and accessible, so that’s not a big deal. It’s also a bit trickier to wire than a Lutron, and it doesn’t look as nice.

That said, it’s nice to have an option for older houses that may not have a ground connection available. People in older houses need energy savings too. Read more

My favorite LED bulbs for 2014

After talking about LEDs last week, a friend asked what my favorite LED bulbs today are. I’m not sure I would say I dislike any of the bulbs that are widely available today, but I do have two favorites.

Compact fluorescent life expectancy

There’s a lot of talk about compact fluorescent life expectancy. I actually tracked my CFL lifespan. Here’s what I found.

I noticed this week that a compact fluorescent bulb in the kitchen had burned out, so this week I bought an LED bulb to replace it. I started writing the dates on bulbs back in 2008 so I could track how long they last. This particular bulb was dated 1-2011. So the bulb lasted 3 years, 8 months. That’s a lot better than a standard incandescent light bulb. I suspect I may have had CFL bulbs last less time than that, but I know I’ve had bulbs last longer, too. The most recent bulb I replaced prior to this one was from 2008.

If your CFL bulbs are burning out early, here are some tips. They work. Remember, my bulbs lasted three years or more.

I have about 16 CFL bulbs left in the house now, and I’ll continue using those until they die. I have around 28 LED bulbs. All in all I prefer LED; they give more lumens per watt, tend to reach full brightness faster, and generally give off a better quality of light, but the biggest advantage–an advantage they have over incandescent bulbs as well–is the complete lack of ultraviolet light so they don’t fade the paint on your walls or the stuff hanging on your walls. Supposedly they don’t attract bugs either, but that seems to not be entirely true. Still, cutting down on ultraviolet light and saving money are good things.

I don’t want my light bulbs on the Internet

I heard this week that the first vulnerability in smart light bulbs has been discovered–they can leak your wifi password.

I suppose I can take comfort in the cost of the bulbs–they cost $129, which means not a lot of people will have them, in a world where people complain about paying $5 for an LED bulb. Then again, for $129, I think it’s reasonable to expect a little bit of security. This isn’t a $15 router with a $2 profit margin. To its credit, the manufacturer immediately issued a patch to fix the vulnerability.

The problem with devices like these with security vulnerabilities is that they will be around a very long time. Read more

CFL bulbs burn out quickly? Here’s what to do.

CFL bulbs burn out quickly? Here’s what to do.

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.

CFL bulbs do seem to be more sensitive to minor electrical problems than older bulbs. Fixing the tab in your light socket or replacing your light switch is often enough to make the bulbs last as long as the package said they would.

The Feit Electric G25 LED globe from Costco

Dave Farquhar Saving money , , , , ,

I spied a 3-pack of LED globe bulbs at Costco last week, priced at $20. This is a ridiculously good price on LED globe bulbs–typically I see them at $15 apiece at the home improvement stores. After verifying that, I picked up a package to try out on my next Costco run. While they aren’t the best LED bulbs I’ve seen, they’re easily the best deal I’ve seen on LED globes, and I’ll be buying more of them. Read more

While installing a new garage door opener, I found a curious statement in the manual: Don’t use LED bulbs. Why can’t you use LED bulbs in a garage door opener? Six words: LED bulb garage door opener interference. Read more

Another month, another go-to LED bulb

Dave Farquhar Saving money , , , , , , , , ,

LED lighting seems to change constantly. I read about Cree’s LED bulbs a good 12-18 months ago and they sounded too good to be true. In a way, they were, because you couldn’t buy them anywhere. The wait is finally over–they’re finally available, though only at Home Depot. I tried out their 800-lumen (60W equivalent), 2700K, 9.5W bulb, which currently costs about $13. It’s a good bulb that lives up to the hype.

These study results on energy savings aren’t surprising

Dave Farquhar Saving money , ,

This Ars Technica article talks about the politicization of energy saving products. Pitch energy efficiency as a cost savings, and liberals and conservatives alike are willing to buy. Pitch it as environmental-saving, and moderates get turned off while conservatives get even more so.

The lesson to marketers: Sell energy-efficient products as technology that promotes energy independence and cost savings. Everyone likes technology, everyone likes energy independence, and everyone likes cost savings.

And the savings is significant. Although I don’t have LED lights and an occupancy switch in every room yet, that’s my eventual goal. Even as electric rates go up, my electric bills tend to hold steady or barely go up, mostly because none of my rooms consume more than 60 watts of electricity to light them, and the highest-traffic rooms turn the lights off automatically after everyone leaves. My total usage goes down some years.

And for what it’s worth, I always preferred LED lights with occupancy switches. The LEDs don’t seem to care how often you switch them off and on; but CFL bulbs do. When using an occupancy switch with CFL bulbs, be sure to put them on their very longest time setting. Anymore, I always go with LED bulbs.
