I am attempting to bu 10 feet of Digi Tech Part number 1647-106458 - 1- ND which I believe is Inspired LED’s 24V-MB240-WW-12M. It is unclear from the website if I can purchase by the foot or if I would be required to purchase the whole roll. When I called the 800 number for Digi Tech the nice lady could not answer that question either and refereed me to this forum. I only need 7-10 feet of a dimable warm white LED tape and I have a 24 volt Dimmer/Driver set up to connect it to. If this product does not come in custom lengths is there a different tape that does and would work with my driver?
