I got one of those bug-zapping LED lightbulbs, in hopes of murdering the flies drifting into my office during the increasingly warm and muggy Pennsylvania summer. I got mine from Home Depot, but the bulbs at Lowes, Wal-Mart and Amazon are all obviously identical. There are two lights in each bulb: an ultraviolet one inside an electrified bug-zapping cage, and a standard 60W-equivalent LED element to light the room. You can have one or both lit simply by turning the light off and on repeatedly within a second: it sounds clunky, but in practice is an ingenious way to cycle the options without adding interface elements.
But it doesn't matter, because they're useless.
I installed my bulb in three locations, moving it every couple of days until a week had passed. As a control, I moved one of those traditional gooey fly strips likewise.
Subjectively, neither did much to stop the flies, a job clearly best accomplished by closing the damn windows.
Objectively, the death tolls were as follows:
Traditional fly strip: 9 bugs, 3 large.
Bug-zapping lightbulb: 4 bugs, all tiny. (The bulb is pictured here, without cleaning)
VERDICT: Don't be tempted: they're not half as good as fly strips and are many times the price. The only advantage they have is not being quite so gross when you throw them in the trash.
Justine Haupt made this handsome and completely functional rotary cellphone. Her design is open-source and you can even buy a case kit from her company, Sky’s Edge Robotics. You have to find and carefully modify your own rotary dial, though — they’re apparently no longer made — as well as a few other components. Why […]
Samsung claims to have developed an “Ultra Thin Glass” for its new Galaxy Z Flip foldable smartphone, signalling scratch resistance and durability beyond that of similar products. But tests conducted by Zack Nelson using a Mohs Hardness Testkit [Amazon] — a set of styluses made of different materials — show that it is no more […]
There is very little evidence that Ring reduces crime. Hundreds of police departments have signed agreements with Amazon-owned Ring to obtain access to the home surveillance camera footage. Interviews with many of them, in 8 different states, show little to no evidence that Ring actually deters criminal activity.
In the early days of the web, everyone wanted a .com domain for their site. As a result, all the good ones got snapped up. But .com no longer has the cachet it once did. In fact, many new businesses and individuals are opting for other top-level domain extensions. One of the most memorable is […]
As you shiver your way through February, you’re probably thinking about paying your heating bill. But in just a few short months, the summer sun is going to come calling — and the fear of pulling that energy bill out of your mailbox will start becoming very, very real. Air conditioning accounts for about an […]
Despite legalization in 11 states and decriminalization in 15 more, marijuana-based products are still an often tough sell with many Americans. While the psychoactive THC portion of the plant remains controversial, the medicinal impact of the non-altering component of cannibis, CBD, is widely hailed. Many portions of those claims still await medical verification, but for […]
