I have replaced as many of the lights in my house with LED bulbs as I can. There are two lamps that I purposefully have not swapped out, and those are the lamps we use as night lights for my kids. The incandescent bulbs are capable of dimming FAR more than any LED bulbs I've tried.

Why?

I understand how dimming has traditionally worked. I also understand the way that LED bulbs work around that technology. What I don't understand is why that limits the lower end dimming limit. Is it because they simply can't make the diodes put out that little light? Are they not able to separate them for individual control?

I recently had my son's bulb burn out and had to replace it with the only incandescent I had on hand. Are there any LED bulbs that can dim really far?
