Yesterday, I replaced three R14 style incandescent bulbs with FEIT R14 dimmable LED bulbs (110v). The LED bulbs are rated at 3.3w each, so a total of about 10w. They are in a fixture controlled by Leviton Z-Wave lamp dimming module VRPD3-1LW. When I turned on the bulbs, they turned on but immediately turned off. I tried several times, same thing. They would turn on and then immediately turn off.
On a hunch, I decided to test dimming. So, I set the dimming level to 50% and turned on the bulbs, they turned on at 50% brightness and stayed on. More testing showed that the bulbs would remain on till about 92%-95% brightness level. If I increase brightness beyond this level, the bulbs turn off immediately. If I connect them directly to the 110v outlet, then there is no problem, they stay on at full brightness.
What could be causing the dimmer to turn off at 100% brightness level? It works fines with incandescent bulbs which are probably about 25w each, so total load of 75w. I am aware that dimmers do not work well with low power LED bulbs. Is this what I am seeing? Just trying to understand why it works perfectly till about 95% dimming level.
