Rectory we removed an old fan that had 4 a19 bulbs in it and replaced it with a new harbor breeze that had 4 cadleabra bulbs, we didn't like the light output or hue so I swapped the cadleabra bases with a19 and place utiltech daylight led bulbs in the fan, which is what we were using before.
Since we're using led, I am not worried about the wattage being prop low.
The problem is when I go to use the dimmer (a lutron led/cfl dimmer), the 4 lights barley dim now. However, if I replace 1 led with a standard incandescent, the dimmer has full range of dimming each bulb from a spotlight too where the bulb is barley glowing (like the rest of the the house).
I tested what would happen with an array of bulb combinations, and if I use 4 incandescent, the bulbs are ver ddim as if the don't have enough power. Additionally, I have adjusted the dimmer dial behind wall, and it has no effect. We also have replaced it with a new switch and that had no effect.
