SYLVANIA SMART+ lightstrip flexablity

Can anyone tell me how flexible these strips actually are? I want to run then around the inside edge of the molding of my front picture window. so they don't have to make a perfect 90, but they do have to make a somewhat tight turn.
This way it can be Xmas lights, Halloween lights, flashing lights for emergencies etc.....

I have one with 2 bends for 90° corners. Mine are mounted under cabinets so I wasn't too concerned but they are flexible enough. I think they will work for you purpose. On a side note, I've had mine for a few years.

I have several sets. If you're concerned about corners, you can buy rgbww corners for them to help or flexible extenders. I have some run around a bed with 90's and they're flexible, but may turn themselves in way that you notice a difference in the light distribution. But yes, they're ok on corners if you're turning a corner front to back. If you're turning to the side, then buy the 90's.

Thanks, that is just what I wanted to know.
