I really like their high brightness - they let a lot more light into the room with existing BR30 based lighting and gently dim down to very low brightness with no flicker - so even on for me obsolete dimmer. Of the twelve, eleven worked perfectly and one failed. I tried contacting Energetic customer service but got no response so I got a loan from Revain to cover the death about a week later. Overall I am satisfied and as far as I know there are no other reviews on them - I decided it was worth the risk to become a Pioneer. Just don't hold your breath for customer service companies.
