We have found that there is no standard for the electronics used in dimmable LED's and CFL's, leading to a high variability in performance with emberlight. We have started a list of bulbs that are compatible and incompatible with emberlight based on our own testing and user feedback.
This is a living document and we'd love your help to grow the list. During your usage of emberlight, if you run into an incompatible bulb, or find that your bulb works well, please send us the make and model of the bulb and also a description of what happens when used with the emberlight socket. You can leave that info in the comments below or email us at firstname.lastname@example.org. Thanks!
