I'm attempting to replace my GE reveal 3-way incandescent bulbs with 3-way LED bulbs. So far I've tried Phillips and Sylvaina bulbs with weird results. I bought two bulbs and had the following results for both lamps. 1. LED bulb doesn't work on low setting 2. LED bulb works on middle setting 3. LED bulb works on high setting with no difference in brightness between middle setting and high setting. 4. Second LED bulb doesn't work at all. I know the lamp is OK cause the incandescent bulbs work fine on all 3 settings. The GE reveals are 30/70/100, the new LED (both brands, dimmable and non-dimmable) are 40/60/100. I called Phillips and they say they don't know what the problem could be. What am I missing here?
