1. Don't get me wrong, I'm not clinging to incandescent, but my LED journey has been quite frustrating thus far. I still can't find a good LED can light or a dimmable light bulb that wouldn't flicker.


2. That's the thing, what IS the correct dimmer?


1. My only advantage is that I started with converting an outside LED solar system to 12 vdc about 15 years ago. So I've had at least 15 years to curse and internally vent my frustration with LED lighting. Back then, all LED's were the small 5 mm solder mount, bullet style and the quality control was horrendous. If you burned out LED's the soldering iron was your only friend.

So, judging by those standards, the current LED situation is a piece of cake.  [smile]  It can be frustrating so that's one of the reasons I've authored a couple of LED threads on the FOG trying to shorten the learning curve for installations.

2. I've had really good luck with Insteon dimmers. I have NOT had good results using Lutron Diva or Maestro although they've recently come out with LED+ versions. I've also had issues with Lightolier controllers.

When I started installing quality RGBWW strip LEDs with controllers, I discovered it is possible to perfectly dim LEDs, but it comes at a price (ps: the theatre industry wouldnt put up with poor control and they have long gone LED),

For single LED lamps i use a programmable LED dimmer module. This enables the dimmer to be set for 100% and whatever minimum the user wants. Once programmed the dimmer provides a good  linear ramp between the two.

This is a level of complexity that we didnt need to bother with using incandescent lamps. I understand the need comes from the uncontrolled variation in LED forward voltages and efficiencies from lamp to lamp.

Perhaps we are also trying to recreate an incandescent lamp which dosent match what the LED technology is more suited to do. As I remodel/redecorate our rooms I have changed  the lighting to use LED strips in 'indirect' settings. This lights the room, without obvious lamps. Especially good for work areas, tv rooms, bedrooms, etc. I can generate a much more even lighting distribution, no glare and adjust the brightness and colour to suit the room, task or time of day. To have done this with incandescent would have been very difficult and much more expensive.

At least in the UK & Europe we have no choice - the efficiency of LEDs is deemed necessary. (ps: 25% of all US electrical energy goes into lighting)

FWIW...for strip lighting applications I really like using this product from Diode LED. It's a driver and dimmer in one unit that fits inside a single electrical box. I installed one in the kitchen 4 years ago with under cabinet lighting and it's been flawless. It probably gets turned on & off 6-8 times every day.

I replaced some fluorescent troffers in my basement suspended ceiling a couple years ago.
They are 2x2 foot LED dimmable flat panels I got from e-conolite but I didn't get the dimmers.

They use a 10v dimmer control IIRC. I couldn't wait to get the lights back on in that space so
I just wired them up full throttle. The switch I use for that light circuit is part of my HA system
and I haven't looked for a low volt dimmer that works with SmartThings.

My lights seem to be ok so far after replacing the back stab switches.

There was a thread here a few years ago that detailed the issues with back stab receptacles & switches.  [smile]

Bringing up the topic of back stabbing devices was  a sure way to generate some laughs on the jobsite.  It was always a sure thing to do a wind up (as the Brits say [smile]) and mention this to our electrician onsite.  [big grin] [big grin] Our sparkies had very little sense of humor about the practice of back stabbing.  [big grin]

Like how they are outlawed in a lot of states since they cause fires? ya...

Seems like you can't do any good with all that back stabbing.
