Is the dimmer module used on these units smooth to 0% or is there a noticeable cut on the low end of the dimmer?

I got a smooth dim thru out. I only ran into an issue when I got to 5 strings in a row.

This is odd since i have installed a number of them in my house and they are completely silent. I used standard on-off light switches too - nothing special. Are you using a dimmer switch? If so, is it made for LED lights and is it robust enough? Other ideas - get rid of the dimmer switch if you are using one, ensure the screw-in bulb end is screwed in all the way each fixture, or other lighting on the same circuit is causing feedback and electrical noise. This is probably not much help but good luck on solving this.

Mine does not remember the last dimmer setting. It normally goes on about half of full power.

I bought one at HomeDepot today and it does dim my dimmable LEDs which I recently purchased from Costco. No issue at all. In fact most of my old 1980s dimmers work fine for these bulbs. I guess you just need bulbs that say dimmable. They dim to a very low level with no flicker. The bulbs do not power off with the dim lever set to the lowest setting which I find useful. If your bulbs are dimmable save yourself 19 bucks and buy this. I bought one at HD and will buy 5 more here to save a few bucks.

When I have my unit dimmed to it's lowest setting I do occasionally hear a buzz although it's only noticeable if I am standing next to the switch.

make sure you turn down the dimmer level located on the front of the metal box - I didn't notice this at first but there is a dial that can be shifted from "-" to "+" Once I turned it down, I discovered my LED lights dimmed down to almost nothing, which was my goal.

In my opinion they're a little dimmer, especially depending on the color you're using. Definitely no hum though.

It works fine with my LEDs so far, but it only goes to about 30-40% dimmer than full bright. I wanted it to go even dimmer.

These G4 will dim partially, dependent on your dimmer, but will not dim linearly. so you will have a partial dimming effect.

In my experience, it turns onto the lowest setting. You can increase the light by touching the dimmer pad.

I have several of these units and have had no problems. I suggest you use a voltmeter to measure both the input voltage (should be about 12V) and the output voltage (voltage should go from about 0V to 12V as you adjust the knob from full dim to full bright. If no input voltage, check the power supply. If input voltage OK, but no output voltage, first check that you LEDs are working by connecting directly to the 12V power supply; If LEDs lite OK, dimmer is bad.

No, they are all clear. IT could be the lighting that makes it seem darker. Our light is on a dimmer and it looks darker when we lower the lighting switch. I love it!

The dimmer seems to work well. The only problem that I have seen that it seems to take quite a bit of tunring before the light comes on at all but then starts very dim and goes to full brightness. I also put in a 300 Watt bulb because the 200W it came with was not bright enough.

This 7W LED bulb dims down smoothly with traditional TRIAC dimmers. There is a faint buzzing sound, but I have to listen in closely (within 1 ft) to notice it.

Work just fine. However I have found only to check the dim was the only time I have dimmed. Look great and easy on the eyes. Hope this helps.

What a great question. I never noticed the issue until you brought it up. All my keys units light up well and evenly except the 2,5,8, and 9 keys, which are still visible in a darkened room, but clearly much dimmer. Thanks for bringing this up.

No buzzing, but with my dimmer switch you need to go to 50 % before they go on. They are wicked bright though (I have 4 on one switch). Also, once they are on, you can go below the 50%. Seems like there is a lot less control than with incandescent bulbs
