The scientific reason you don’t like LED bulbs — and the simple way to fix them

 

There’s a handy trick for reading station signs that otherwise fly past in a blur as you travel in a high-speed train. Look at one side of the window and then immediately at the other side of the window. When you change your gaze, your eyes will automatically make a rapid jerking movement, known as a saccade. If the direction of the saccade is the same as that of the train, your eyes will freeze the image for a split second, long enough to read the station name if you time things right.

Saccades are very fast movements of the eyes. Their exact speed depends on the size of the movement, but large saccades can move the eyes at the same rate as a high-speed train. The image of the station name becomes visible because it is travelling at the same speed as the eye, and the images before and after the saccade are blurred and so don’t interfere with the image of the sign. This shows us that our vision is still working when our eyes move rapidly during saccades.

not me

While I retrofitted most bulbs in my house years ago with CFL, I never liked them. I've subsequently re-retrofitted an even larger fraction with LED, and I do like them.

I've noticed that of the diverse types I have bought the turn-on time varies noticeably, most seeming to hit 90% light in something like 0.2 to 0.5 seconds. In other words they turn on slower than conventional incandescents, but way faster than any of my fluorescents of any type.

Still that time is enormous compared to the actual time for an LED junction to generate light when voltage is applied, which implies that internal electronics in the bulb which interface between household 120 AC and the DC requirement of the bulb are taking a bit of time to get going.

The obvious candidate is charging time for a capacitor. If that is there, then why would the makers have the voltage supplied chopping to zero at the claimed rate? I'd like to see real data on the claimed flicker, from a broad sample of randomly chosen commercial products. Not a worst-case, somebody found a screwball design as bad as...

The main bad things I've seen with LED household lighting are high prices and very limited availability (and even higher prices) for the higher lumen levels.

Color rendition, power efficiency, lifetime, dimming characteristics, and most other things are so far superior to my CFL experience as to have made me very glad to have done the swap. I've even replaced twenty "40 watt" fluorescent tubes with LED models. That got me about a factor of two in power efficiency, better color rendition, and vanished ballast noise.

LED's

Like archae86, I too had changed all my bulbs to CFL, but the ones that were a warm light, not the rotten bluish color.

About 2-3 years ago the electric company gave out great discount coupons for LED bulbs. I completely changed over to LED bulbs, some are like chandelier type others are dimmable and with the coupons they were dirt cheap.

So as not to waste the CFL bulbs I took them with me to Mexico where you can almost only get the rotten bluish CFL's.

I actually have all

I actually have all different kinds here. I have a halogen incandescent in my stand lamp because at the time I couldn't find dimmable LEDs. The kitchen has a LED for the range hood and a flourescent with ballast for regular lighting (apartment building). The bathroom, my roommate's desk lamp and my table lamp use CFL. I'm fortunate in that electricity is included as part of my rent, but I like the idea of not having to replace LED lamps for a few years. So as the older technologies burn out, I'm switching to LEDs.

A wish

My only wish for home LED lighting is that the cost of the LED dimmers comes down. Old incandescent dimmers don't work with CFL or LED lights and the needed dimmers are $30. I have one light set with a dimmer now but would like to do two more if only the prices come down.

LED Lights

I've converted all the lights in the house toLEDs and I'm very happy with them.

Lights in our 5th wheel were all converted to save drain on the 12 volt system. Of course all the marker, stop, turn signal and cab lights on our Freightliner tow vehicle have been changed over!

I have a room where I had to buy the LED dimmer because the dimmable bulb in the regular dimmer would flicker and I do use the dimmer often. The LED dimmer works perfect, it was costly but worth it to me.

I had a two foot fluorescent bulbs in a very hard to get to spot over the kitchen sink, light is used a lot so they'd burn out often and changing was a real pain in the ... Changed over to two foot LED bulbs with an expected life expectancy of 10,000 hours, did the same with the 4 footers in the basement.

Just this weekend I finally changed the ceiling fan lights to LED now that they make them and have come down in price.

Only two spots left, the bathroom has a circular florescent and the refrigerator is still incandescent.

The two dimmable LED recessed lights in my kitchen were first tried with the existing incandescent dimmer hard-wired from the 120V circuit to the two LEDs. The dimming available from the incandescent dimmer was negligible. Swapping it out for a CFL/LED dimmer ($30 from Home Depot), and properly setting the internal adjustment on the dimmer, the two LED recessed lights dim very well, right down to nothing. There may be some LEDs, maybe multiple higher-wattage LEDs, that will dim with an incandescent dimmer, but for my double low-wattage LEDs, they required the CFL/LED dimmer.

It's always worth trying the old dimmer with new dimmable LEDs, but don't count on not needing a new $30 dimmer.

At first the incandescent dimmer worked with my "Cree" (Home Depot brand?) LED lights, but the bulbs didn't dim very much before just going off and ended up with a noticeable flicker. Installed a proper LED dimmer and the very same bulb works as it should. I'm told the reason is the LEDs low power wasn't enough for the incandescent dimmer to work properly.

I have had several Cree bulbs go dark before a few months of use, but they have a 10 year warranty so they were replaced with no problem or hassle, I didn't even have the receipt. This was a year or so ago. The replacements have been going strong for over a year now.

I've been using 3 dimmer switches which have been installed for many years and they are dimming my LED's perfectly from a barely visible glow to top brightness, just as they did the incandescent before. One dimmer does a six bulb candle style chandelier.

Maybe, my house was built in the 1950s the wiring from back then was a nightmare compared to today's stuff. I had a larger junction box and new outlets installed but all the light switch wires are original. That could be the problem for all I know. I had 3 rooms on a dimmer with the incandescents with no problems, once I put in LEDs they all had a much shorter light span and a noticeable flicker at any level. I did away with two of them and switched one that I used a lot to an LED specific dimmer and it's all good now. When I mentioned the flicker to my brother, who is an electrician by trade, he said what I've mentioned already, that the LED bulb didn't draw enough power to operate correctly and get a LED dimmer.

CFL to LED

I have gotten rid of all my CFL's and incandescents. In the kitchen and bathrooms we had open can lights that I am sure siphoned off a massive amount of heat in the winter into the attic. I replaced all the can lights with the plug in conversion to LED's that also sealed the hole in the can going up into the attic. I could not be happier. Most of the LED's are on dimmers. I did get dimmers that specifically stated that they worked with LED's.

We initially switched over the lights that were always on at night. I started seeing a savings in energy immediately. Then we slowly replaced all the older technology lights with new LED's as they came on sale.

Better lights, longer lasting, less money spent on energy. All around winner by changing to LED's.

Yes.

Not all dimmer models of a given generation are the same, and for sure the characteristics of current LED bulbs regarding dimming and dimming compatibility vary a great deal. Any advice you get that is not specific to a particular pair of dimmer and bulb may be incorrect.

My advice is first "just try it". You may be satisfied with the dimming behavior of your new LED bulb with your old dimmer. If you don't like that, consider whether you need dimming at all on that circuit, and if not just swap out the dimmer for a simple switch. Failing that, you may want to consider buying a new dimmer that claims LED compatibility, but be aware that the actual dimming range will quite likely be a lot less than it was with an incandescent, and that if you put more than one LED bulb of differing types on the same circuit, their dimming profiles may not match very well.

My house came equipped with dimmers on almost every lighting circuit and with hideously inefficient hundred 130V incandescent bulbs installed. I converted about half the circuits to simple switches during my CFL conversion wave some years ago.

With all that, I'll say my LED bulb dimming experience has been considerably better than my CFL dimming experience.

Wattage

Wattage is 5.5 watt each. But in two locations there are two bulbs and the chandelier has six. All the rest are single bulbs without a dimmer.

We have fluorescent in the ones you can't see.
These cans are the larger ones (10 of them in just the living room) and I have been looking for led lights that are larger to fit them. So far haven't found the ones I need.
I never turn on the living room cans as they are all 100 watt bulbs and I cringe at the thought of how much electricity that would use.

Also, just what sort of incandescent bulbs are currently installed in yours. Perhaps floods like BR30 or BR40? Something else?

Melaqueman wrote:

By that definition I have an appreciable number of two types of can lights in the house. Both were originally equipped with 130V incandescent flood lights. All are currently equipped with BR30 or BR40 LED lamps of varying lumen rating and beam width. As the living room ceiling is fairly high, I put a high lumen rating BR40 with moderately low beam width in a fixture I can point right at the music desk on my piano. The other location I have narrower than standard beam width lights up the reading rack on an exercise machine.

The brightest one I have went to a high location in the work area of the garage. Those were special ones I found to equip the ceiling fixtures in the church sanctuary. The church fixtures were a pain in the neck forever. While rated for survival with a 300W incandescent bulb, they were only about 2 feet in diameter, with no ventilating holes, so the bulbs got significant lifetime impairment from self heating. A music teacher ran them many more hours a week than the room was in use for the church, so with eight fixtures someone was running up a ladder to change a bulb once every few weeks, and even so a Sunday visitor would seen one or more dark fixtures quite often.

The LED replacements were over $50 each. Their lumen rating of 2500 was well below the original incandescents, but they were wide-beam floods, so much more of their light got to where it was needed. Bulbs with about 36W of power consumption lit the areas of interest just about equivalently. Though not rated for enclosed spaces, I don't think they get frighteningly hot, as they actual power dissipated in the fixture is perhaps 7% of what it was before. No failures in three years and counting. Somewhat to my surprise this model (Feit BR40/DM/2500/3K/LED BR40 Dimmable LED, 250W Equivalent, 3000K) remains available, and has come down to $35.

I think in the current marketplace, availability and price of the lumen output higher than about a 100W incandescent, and dimming properties are the biggest shortcomings of LED lamps.

when I look at CFLs and LED

when I look at CFLs and LED bulbs some are obviously marked DIMMABLE some obviously not.
The bulbs are made different, so I would suspect that some ppl have success with dimmers and some not.
Lacking the AC 2 DC conversion an LED bulb is instant on/off with 12vDC applied. Watch a car's tail lights and you can tell they are LEDs by the instant on/off. Incandescents must warm up and cool off so they cannot be instant and you can actually watch them turn on/off.

For what it's worth, the LEDs that didn't work with incandescent dimmer switches I've mentioned here a few times are rated as dimmable LED bulbs, as mentioned once switched to a LED rated dimmer switch the same LED bulb worked as it should.

I have switched my whole house to LED bulbs slowly. I have 12 Phillips Hue bulbs in the house as well. I am using these Hue bulbs in the areas where I need dimming capability. I can dim lights with phones, Hue dimmer switches or Google Home or SIRI. So I don't have any experience with existing dimmer switches. Earlier I used to have X-10 switches for dimming and other remote control purposes. Again it is my personal choice and not recommending to anyone.

LED Dimmer Switches Causes Static in AM Radio

I changed my lights over from incandescent to CFL some years ago. Now almost all CFLs have been changed to LEDs. As I've changed over to LEDs I've changed most of the switches to dimmers. I found that the LED dimmer switches causes static in my radio. I found further that changing radio reception to FM from AM gets rid of the static noise. Fortunately, my favorite listening radio station broadcasts in both AM & FM.

Recessed lighting is a better label

My "can lights" use the large screw in bulbs. All the led ones I have found so far are smaller and do not fill up the space from the bulb to the fixture.

Can't use outdoors

My only complaint with the LEDs is that I cannot use them in my sensor lights outside. They flash like a strobe light all day long. And another sensor light they act like a dimmer switch and glow softly.

Sounds like BR40 to me

I'll hazard a guess you want BR40. While the prices are not great, there are plenty available. For example:

https://www.1000bulbs.com/category/led-light-bulbs/

If you click the BR40 link, you'll see lots of options, varying in Lumen output, beam width, color temperature, and brand, but sadly clustered near $10 each.

A quick check with a ruler should help tell whether BR40 is right for a particular fixture. Some of mine are BR40 and are pointable, while the others are BR30 and not pointable.

One caution: most LED floods are wider just above the screw-in base than are most incandescents. Some fixtures don't have the room without an extender. Look before buying. Not all the LED floods have the same shape there, so you still would have bulb options.

How well do LEDs work in cold environments?

Bought a new upright freezer last year and it came with an LED bulb. It worked off and on - mostly off. Didn't expect it was the bulb - thought it might be the door switch and almost called Sears. Just for fun, I bought an incandescent bulb that fit. No issues since. Now I have an LED bulb that doesn't fit anything else.

Pleasantly surprised

Changed the entire house over to LEDs last year when our Hydro company offers 50% off the bulbs and I must say we're impressed.
We picked and chose the appropriate colour and K intensity for the application and everything is working as advertised..no problems at all in the outdoor fixtures with temps in the winter going down to -35c..
We've noticed a big savings as well, even having them on longer than incandescent bulbs..
The daylight bulbs are a must for winter reading!
