Greetings.
Have any of you delightful people tried LED recessed lighting in your studio? If so, what were your findings? Any issues with buzzing; either with or without a dimmer?
Other thoughts/anecdotes/advisements/knock-knock jokes?
Thanks in advance, -09

I have tons of it . . .why?

oh wait . . . works great, it's cheaper, it's easier on the eyes and no buzzing with dimmable bulbs. Choose wisely. Dimmers and bulbs.

I've got LED strip lighting above my ceiling clouds and use LED bulbs in everything else. No problem at all here. The only thing I don't like about a lot of LED options is the cold sterile nature of it. It took me some time finding the right brightness/warmth in the bulbs.

You have to be careful what LED lighting you get. All LED "light bulbs" contain a tiny switching power supply to feed the LEDs. As we all know (I hope) searching power supplies spew copious amounts of RFI unless the outputs are adequately filtered.
Some LED bulbs have great filtering, some have effectively none. The quality of the filtering is not related to the cost or to the reputation of the company (for example, Phillips LED products rank really low for noise pollution. Not low pollution, low ratings.) So you need to do a lot of investigation and perhaps some testing one's self before committing to a particular brand of LED lighting.

You can go the pro route and install the low voltage units that have remote power supplies. Then the bulbs don't have noise issues.

All of my lights are LED (Phillips Hue), none are recessed. I can dim them to my hearts delight via WIFI (or someone else consternation.) No buzz.

Lutron makes some really good dimmers for LED's. (About $50 a pop or so) You want to make sure your LED arrays are dimmable, then use the Lutron's and it's all good. DO NOT use standard in the wall dimmers for incandescents.

DO NOT use standard in the wall dimmers for incandescents. Installed many of these and they're great. Their 3-way approach is really cool too (no traveler wire required, just a remote switch) and having full control via the app is awesome. Turn the whole studio on with one touch.

I've got a bunch of can lights I need to put LEDs in.

I've got a bunch of can lights I need to put LEDs in. Lutron Maestro. C-L Dimmers. Not sure what the brand of LED's are. They are drop down from ceiling on a "rail". Fairly expensive. Not home depot specials. Got em from a lighting place.

I have LED track lighting, no buzzing. Using basic GU10 LEDs from Amazon.

Well, let us know how it works out. Note that it doesn't really matter if it's a "bulb" or not - any LED lighting device must, by necessity, contain a miniature switching power supply. (EDIT: Unless it runs off an external supply) If you Google "LED lighting noise" or something similar you should be able to find a few articles about it.
Some of them give noise ratings for some common lights, none that I've seen a very comprehensive though. I'd also want to consult an LED lighting specialist.
In the case of the units you linked to I'd be a bit suspicious, as they state that they're designed to be used with standard 120 VAC in-wall dimmers and, as we know, typical in-wall dimmers also spew RFI.

That does put the driver in the ceiling, so less hi frequency noise issues directly from the bulb. These are close to the industrial units that I was talking about. I would be curious if you can remotely mount the jbox and just run the LV wiring to the "cans". They may make extension and or dasy chain cables for them. You would probably need to go to an actual lighting or electrical supplier for good info.

I've installed about 20 or so of that type of IC LED all-in-one fixture. 3" and 4". Commercial Electric that HD sells and some from Lowes. Two of the CE ones went dead in a few months and just lost a Lowes one after a little over year. The rest are still going strong. Bottom line is that they're good value and look great (plus being IC) but some will go bad on you. HD quit selling the ones I installed so it's going to take some effort to order replacements if they're even available at this point. Other option is a replacement the same size. Pain in the ass to wire them up all over again though.

I've got both recessed LEDs and installed strips.
No problem with switching noise.
Besides, switching noise problems have always been overblown in the studio world talk, and any instance could likely be traced back to a wiring/installation issue.

I have a shitload of all kinds of Philips Hue lights, including the recessed ones, in my studio. Love em. No hum whatsoever.

The Philips Hue series looks great but very expensive per bulb. Maybe someday I will be able to afford them. Right now, I have (16) LEDs in my home studio and went through a couple different brands. I had some Philips and GE LEDs go bad very quickly. I then started using the less expensive Home depot Eco Smart LEDs in a GU10 base to fit my track lighting. I've only had one fail on me in the last year. My favorite part is that they don't get hot. the studio is always kind of warm due to all the gear. It was unbearable when I had halogen lamps. I have an LED compatible dimmer. I think it is a levaton. No noise.

So you need to do a lot of investigation and perhaps some testing one's self before committing to a particular brand of LED lighting. Go the DIY route and use a DC power supply. Easily dimmable by using a PSU you can control the voltage or current of. No interference from the LEDs and the wiring and you can stuff the power supply where it's far enough from sensitive wiring/gear. I've seen some pretty lousy builds in constant current LED drivers. And it's not price related...

And it's not price related... HMmmm. Have you actually tried that? I don't have experience with LED dimming, but most lighting dimmers I know of control the light by altering the duty cycle of the AC, not the amplitude of the voltage. That would lead me to think that an LED dimmer would be contolling the duty cycle of pulsed DC.
Don't LEDS have a fairly narrow range of voltages they respond to?
I'm asking because I don't know.
