Envision and Paramida LED's are junk. I got sent to a client's mountain cabin to change all light bulbs in the house to LED's and all can trims to LED's. They wanted me to get the bulbs through a lighting store they use regularly. These two brands claim to be dimmable and are not. They seem to works on off fine on a regular switch. As soon as they were put on a Lutron C/L dimmer they turned into strobe lights. I also had multiple bulbs come out of the box in pieces. So I had to go home and then drive back up at a later date after ordering Feit bulbs through my distributer. Stay away from Envision and Paramida.
