Mounted flat on a surface is the ribbon flexible enough to turn a 90 degrees or a tight turn ( not wrap )

Thanks for your interest in Armacost Lighting RibbonFlex PRO. Turning this product at 90 degrees will damage it. To most easily do this, you should use SureLock corner connectors or assortment pack. Alternatively, you could cut at the copper pads and solder wire on to those pads to make the connection or make a very loose soft bend in the tape light.
