(like the ones used in promotional musical CD box). we need, under specifications, like speed/interval cicles. Thanks for any help PP Pellegrini

This device may be configured with external components selected to provide the flash rate you want, and there is sufficient drive current to power the LEDs. Regards, Pete Sorenson
