It was too long for my mount so I couldn't put the jar lid back on but it's not their fault as the sizes are listed. However, I am not completely satisfied with the dimming function. As the brightness dropped to around 40% it got brighter, probably as bright as it was at 70%. Then, like all LEDs, it turns off completely when you turn it down to about 10 or 20%. Even on the lowest settings it still worked, it was still very bright. It's definitely not mood lighting. I would give it 2 or 3 stars for poor dimming, but I also understand that the quality of a dimmed LED really depends on how compatible it is with your particular dimmer, so it might work great for you.
