Many years ago I ordered mine from here and they worked great. Many options to choose from. You can cut them to any length you need. They seem to be out of stock in the bright white, but soft white is available.
Years go I had a set very similar to those ...kinda got yellowed over time and quit working ...I then went with the Dust2Oasis 5' color strip w/remote ...worked well in my 2man flip ..I even got a 10' version for my hub last season..this season I got the Power Practical 10' color w/remote ...these are very nice lights..I would 100% recommend them ..and at the discounted price its a no brainer . Mine are going to be hooked up to a knock off 12v M12 Milwaukee power source .
