The only reason I didn't give 5 stars is because I think the bulbs I bought them for are defective , so I've never seen them do the job I thought they would do. However, they work! - I intervened and modified one. It definitely carries a signal when I flipped the switch because I messed up the ground pin in the socket. DO NOT DO THAT. I BEND AMBITIOUSLY AND PAY FROM IT OFTEN. The item is well packed. Made of good materials, durable. I keep them on the shelf because who knows when I'll find a need and purpose for additional or retrofit lighting. Adapters are handy. **I tried using these to adapt a 300w CFL lightbulb to a standard sized magnate base. But I couldn't do it with lightbulbs. Even if I put them in a matching lamp with an E39 base. So the fault is again in the lightbulb. Not Dikuno.
