The magnets are powerful.
It works well.
Unfortunately, in this version of the LED lights, the individual LEDs appear as protruding light points, and thus there is no uniform light surface as seen in other previously purchased lights of what appears to be the same type. As if that weren't enough, the "3-color effect" is generated by two different groups of LEDs and not within the LED itself. This allows you to see white and yellow LEDs at the respective medium color temperatures. Not just a flaw of beauty. If you look closely at the product images, you can at least make out this non-homogeneous, i.e., point-like, luminous image. So keep your eyes open when buying light bulbs!
everything is okay
I recommend it; it's better than I expected.
These are not great. I bought others that were much better quality and the battery lasts longer.
