Hi All,

I am looking for defused, flicker free LED light bulbs
(5000K, 60w equiv). Had no luck with the Phillips
(waste of money). I see a lot of reviews but then
people complain about the flicker anyway.

You guys have any tips?

Many thanks,
-T

Flickering all-the-time ? .. intermittent / random ?
.. when other devices are going on-off ?
I have several LED bulbs in my home and the only
flicker I notice is the kitchen ceiling fan lights - 1 flicker -
caused by the laser printer coming to life for a print job.
The printer is in the next room but may well be off the same circuit.
ps : have you tried dimmable vs non dimmable ?
I think all of mine are dimmable ..

Constantly

My sister can see 60 Hz and 120 Hz flicker. Gives
her a massive headache. She still uses incandescent
bulbs because of it.

I personally can not see it.

I've worked in the 25 Hz flicker -

Hope you / she find a solution.

Shouldn’t be on the same circuit since lights are on a lighting circuit and
power points are on a separate higher current rating circuit. At least,
that’s the way it’s done here.

Found these

When I added electrical service to a shed in my back yard, I added a 15-amp
circuit for lighting and a 20-amp circuit for receptacles. In my house, however,
the builders created one 20-amp circuit per room, mostly. Bedrooms 3 & 4 are on
the same circuit. There is no area of the house where there's a separate circuit
for lighting and receptacles. I wish there was.

Yup, when an appliance trips a breaker or blows a fuse, the lights go
out and you're in the dark. Not good.

Depends on how many circuits there are.

Not all houses are wired properly. Clueless homeowners do a lot
of strange stuff. I once saw a house that used lamp cord instead
of Romex in an attic--and it was laid on top of the joists where
it might get pinched if someone laid down plywood for walking in
the attic.

LOL, yes. My house was once owned by a bosun's mate who fanied he was
an extrician. Almost 30 years later, we are still rooting out bad
wiring.

I've been using these for a couple of years now:
https://www.amazon.com/gp/product/B07PZSTX8B/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

Quite bright. No noticeable flicker at any time. Rated at 13w, but
much brighter than a regular 75w bulb. None have failed yet.

In fact, the description includes: "No flicker or strobe. Each bulb is
stict (sic) tested before ship, no need to worry about the problem you
suffered before with other bulbs such as flicker, strobe, glare and
color rendition. Healthy for every member of your family. "

It is "T", trolling you. The frequency used in LED lights
cannot be distinguished by the human eye as "flicker"
(aside some special purpose bulbs like christmas lights).

Mine was a new house in Baltimore owned first by a man from Louisiana.
He was always cold here so he caulked like crazy. Except he couldn't
caulk a straight line and around the doors, it got over the bricks
outside. He also taped all the windows around the edges, but not very
neatly. They already had storm windows but maybe he had put a layer of
vinyl under the tape. (Bought the house in May so he would have taken
the vinyl off.) I could get the tape off but there was stickum left
behind.

He also put extra wall on 3 sides of his bedroom. Each wall was done
differently. He explained each one to me but I forget a couple details,
but when I put wiring in the rear wall I saw that he had put pink
insulation and another layer of sheetrock. Something similar on the
side wall (which also covered the phone jack, so I had to put in another
phone jack). And the wall next to the other townhouse next door he put
in a layer of cork and a layer of sheetrock. He might have moved the
clothes rod forward to make up for this and it was still deep enough to
hang things up and close the doors.

The cork was for noise, and the other two walls were for warmth, and I'm
sure they help a bit.

T trolls so much you can't tell if he's just crying wolf or being
serious. If he's being serious, I suspect the flicker he's complaining
about is due to either overloaded or poorly wired electrical service in
his home rather than either from what his electric company is providing
or from the circuitry inside his bulbs. The flicker he's complaining
about is probably due to short duration voltage drops when a high
current device turns on (heat pump, refrigerator, etc.) If he lives in
a multi-unit dwelling and the wiring is sketchy or the building's
service panel supplies insufficient current, the source of the voltage
drop might not even be in his unit. I have several Phillips LED bulbs
and none of them flicker except very briefly when I turn on a laser printer.

I have some in the kitchen that sometime flicker when dining room
fixture with dimmer switch is turned on and changing the dimmer can stop
the flicker.

T is certainly not reliable, to say the least, but dyno dan posted bulbs
that advertise "no flicker", so it makes me think that maybe some do,

Do LED bulbs flicker, gives a lot of hits in google.

Here is one that seems longer than others and maybe the OP (oh, that's
T!) should read.

About the frame rate of movie film. I've wondered if that has anything
to do with old movies being called "flicks".

When I said I hadn't seen LED flicker, I did forget about that one. I
have had a LED bulb designed to flicker, to simulate a candle flame.

I've been using them for years, different brands, never noticed. Given
that you have a 60hz current, it may be possible that some people would
be sensitive to it. Similar to the pitch of some sounds that can drive
people nuts.

I like that LED bulbs last a long time too. I did have one go bad once
some years ago, but otherwise, never replaced on.

I have had a few die.

well, the typical AC operated lamp (light bulb) is
actually "blinking" at _twice_ that number, as it
illuminates on both the (loosely speaking) "up"
and "down" stroke...

So that 25CPS [a] lamp is actually usually blinking
50 times/second. (and the standard US 60hz is
flashing 120 times/sec...)

sidenote: back 1975ish I was in the NYC subway station
right next to Penn Station, and the incandescent
lamps were... yes .. wired to the 25 CPS of the
rail road supply. Who knows why?

Anyway, it was a super cold winter, about zero F,
and yes, I definitely saw the flickering.

Hmmmm... I don't know about the early movie
projectors, but don't the modern ones, umm,
make that 1940ish?, do a double flash od
each fram?

[a] ain't none of this silly "Hertz" deal back then..
