Which LED Bulbs are Greatest For Constructed-in Dimmers? > 자유게시판

Dwelling in a house filled with dimmer switches could make the lighting aisle appear extra intimidating than it ought to be. Sure, plenty of right now's LEDs are designed with dimmability in mind, but that does not assure satisfactory performance. We've heard loads of complaints from readers, EcoLight and likewise experienced first hand the annoyance of spending money on upgraded lighting, solely to discover that these fancy new bulbs can buzz, flicker, and dim erratically. In the curiosity of constructing your subsequent trip to the lighting aisle a little less exasperating, we put in the present day's LEDs to the take a look at. There are many things that may cause a mild bulb to buzz or flicker when it dims, including issues past the bulb's management like voltage irregularities, overloaded circuits, and outdoors interference. The commonest difficulty, though, lies with the dimmer itself, and that is where we decided to start out. Trendy dimmers (the sorts you may discover on the shelf at Lowe's or Residence Depot) will not really increase and lower the voltage for easy dimming, but will instead flash the ability up and down at unnoticeably excessive speeds to create the illusion of dimming.

These rapid-fireplace swings in voltage create electromagnetic resistance within the bulb, which could cause things to vibrate and buzz. You do not need that. We began with a simple rig using a few frequent dimmer switches. We chose an LED-suitable model from Lutron, an identical Leviton change, and a cheap, $5 triac rotary dial intended for incandescents solely. Although we aimed for EcoLight solutions a very good representation of what is on the market, there are clearly greater than three sorts of dimmer switches available on the market. As such, your mileage could differ -- particularly if you're utilizing an older model, LED bulbs for home or something more high end. Interestingly sufficient, every LED that we examined dimmed with all three dimmers, even the one rated just for incandescent use. That lends plenty of credence to producer claims of broad dimmer compatibility -- however it's solely the beginning of the story. As you'll see, dimmable LEDs usually are not all created equal. Dimming annoyances aren't a new problem -- and they aren't an issue that's unique to LEDs, either.

The tungsten filaments in most incandescent bulbs are particularly susceptible to the excitement-producing vibration attributable to in-wall dimmers. Sure enough, EcoLight solutions the 60-watt incandescents that we examined out in our rig put out a noticeable buzz throughout all three switches. Even without filaments, LEDs have loads of components that may vibrate and produce that annoying buzz, and most of the ones we tested did just that, EcoLight solutions even effectively-rated bulbs like the Cree 60-watt replacement LED and the GE Reveal LED. We rated each bulb's buzz on every dimmer utilizing a five-point scale -- very quiet, quiet, moderate, loud, EcoLight dimmable and very loud. The outcome you want is a bulb that rates "very quiet" throughout the board, as even a "quiet" buzz can get annoying in a quiet room. For essentially the most half, EcoLight solutions the buzzing within the LEDs we tested fell somewhere within the middle: fairly reasonable, however actually loud sufficient to be a professional bother. There were two standouts, though -- one good, and one not so good.

Apparently enough, EcoLight solutions they each came from Philips. The overachiever was the current generation of the company's normal 60-watt replacement LED, reduce energy consumption which ran darn close to silent throughout all three dimmers. We couldn't even hear anything after we dimmed it using the cheap, EcoLight solutions incandescent-only dimmer. Bookending the other end of the spectrum was the Philips SlimStyle LED, which produced the loudest buzz of any bulb we examined. This makes sense when you consider that in trials like these, EcoLight smart bulbs buzz is actually just a product of a bulb's design. With a radically completely different shape from the usual, near-silent Philips LED, together with a reorganization of the diodes themselves, it is not terribly shocking that the SlimStyle's buzz is so much louder. All that stated, it is price reiterating that we did not notice an audible buzz with any of those bulbs when using them with commonplace wall switches, so if you do not use dimmers in your house, then an affordable LED just like the Philips SlimStyle might make lots of sense.
