Thread starter Electric-Light Start date Feb 4, Electric-Light Senior Member. I am one of the many who hates flicker with a passion. You've probably seen tail lamps on newer cars look like flying tiny dots when your eyes scan across even though they look steadily lit when there is no relative motion. It flickers so much that I'm pretty sure this type of LED driver ballast hui8011l the record for the most flickery general service lighting apparatus in the history of electric lighting.

Incandescent bulbs have very little flicker and has been regarded as the gold standard of lighting flickering. The filament's thermal capacity keeps it glowing through the zero crossing. Fluorescent lamps have after-glow. Glowing hot arc tube of MH does the same thing. LED or its phosphor coating have almost no after glow to buffer flicker. There's really nothing in Energy Star that clamps down on this. Until standards become established and pressure continue reading LED industry to disclose poor performance or stop pushing out extremely flickery products, it is important to bench test a fixture before installing the lot so you do accidentally install a lighting downgrade.

A fixture with this much flicker would produce multiple image effect on anything in motion and it will be obvious. Just for your reference:. Location Interesting post so in the graph up there light output is flickering because the LED is not running on smooth DC? What kinds of LED's do you find flickering the least flicker? Location Shelby Twp. MI, near Detroit. Most flickery??? I think you meant highest flickerisity Electric-Light said:. Kind that use a ballast with very low ripple current.

Like a computer power supply? The concept of a "ballast" "driving" an LED I dont quite get can you explain further? When I think of a ballast I think of a lamp that needs "starting". A old fashioned hui8011l would be a transformer that can send a hi voltage spike along with a starting cap to spark or ignite an arc lamp. Also it would include a running cap.

Like HID lighting, and fluorescent. I suppose the newer electronic "ballasts" are like VFD's changing the frequency, but they still have to "start" the lamp and the lamp is still AC. Sorry, but I'm a little skeptical that led flicker is any kind of issue in any of the brand name fixtures, and even more skeptical its an issue in any quality fixtures.

There is just no reason in the world any manufacturer would pulse the LED's slow enough to make this an issue. Sure, manufacturers can pulse the LED's on and off. It even saves energy to do that.

Remember the old calculators with the 7 segment LED digits? They never lit up more than one digit at a time. A chip would send a clock signal that would light up one and only one digit at a time. Turning on more info 8 as the same time would have fried the small battery powered electronics. But just like you old TV, they all looked like they were constantly on because the eye responds to the peak level of brightness.

So lets make some comparisons. Fluorescent lights with magnetic ballasts pulsed the tubes at 60 hz. Some people claimed that could be perceived by flickering people, and continue reading quite possible. If you hold your phone camera up to such a light, you can easily see the flicker on the phone display as a series of darker bands that move across the fixture.

The scan frequency of the phone camera combined with the 60 hz. We also know TV's scanned at 60 hz, click here that is fast enough that is usually fast enough to produce smooth pictures and motion.

So 60 hz. However, when we get a little higher, say to hz. Bump it up a little higher to the 18, hz or more of a fluorescent ballast and the flicker can no longer be detected with a phone. I just see no reason in the world any manufacturer would use a frequency for a LED light fixture low enough to have flicker. The simplest most basic electronics hui8011l the world can easily make an LED driver that works high enough to make flicker not an issue.

I've looked at a couple of LED lights with my phone since you posted this, and they have detectable flicker with whatsoever. They would basically be equivalent to flickering fluorescent light with a electronic ballast. Hui8011l think its more likely you hui8011l a couple of bad lights.

The concept of a "ballast" "driving" an LED I dont quite get can you explain further? But to avoid the effects of LED flicker, you and your flickering will need a basic understanding of the issues behind it. Huu8011l would simulate the solution used by the electronic ballasts that hui8011l powered fluorescent lighting for many years. Plinths and Cupboards. Bump it up a little higher to the 18, hz or more of a fluorescent ballast and the flicker can no longer be detected with a phone.

Not all problems that hui8011l flickering are trivial, but if you have a strategy to eliminate all the easy-to-fix possibilities, you'll know when it's time to call an electrician. Loose wiring and flickering faulty connections can also cause problems. Check this out makes LED lights flicker? However, if all the lights flickering are on one circuit, it's easier to isolate the problem than if random lights throughout the house are flickering. Let us know so we can make you our top priority! So lets make some comparisons. If a single light fixture is flickering, you filckering be fairly confident that the problem is isolated flicering that fixture or the switch that controls it.

Bump it up a little higher to the 18, hz or more of a fluorescent ballast and the flicker can no longer be detected with a phone. If your incandescent light bulb is flickering, you may have simply neglected to tighten it. Fluorescent lamps have after-glow.

Once you've eliminated the bulb as the cause of the flickering, turn your attention to the switch. In the UK, that will result in a frequency of potential flickers a second. Consider using a constant-current LED driver. Log in. If not, it points to a loose connection somewhere in the circuit or a faulty breaker. Eliminating the breaker as the cause of the flickering leaves the probability of flickering loose connection somewhere in the circuit. It could be in hui8011l fixture, a switch or somewhere behind the wall.

This was because — unlike incandescents, halogens and fluorescents — LEDs have no http://ovdijahel.tk/and/barber-shop-on-7-mile-and-evergreen.php. Instead, it simply converts current from AC to DC.
