I have two plug in table cord lamp dimmers. One flickers, other works perfectly and is made for an LED dimmer. I enjoyed this light bulb because at night I turn it on low, when I have to get up, and it makes red-ish light that allows me to sleep well. During the day I can turn it up all the way and it is blue-ish daylight color.
The blue light can really keep me from sleeping. This light really solves that problem. I use this bulb in a touchier lamp with a dimmer close by. I tried five or ten bulbs. This one works best. No more headaches from daylight at nighttime when I have to get up for a few minutes.
