I bought these lights in 2 orders (2x and 3x) and am very satisfied with the brightness and color of light. However, these lamps have (from two deliveries) an unsightly side effect: when they are turned off, it flashes (like a flashlight) 2-3 times in untereschiedlichen intervals! Mind you, the lights are off.
Therefore, and because the vendors so far not responded to my email request for the cause I rate the lamps being only 2 stars.
