Most LED light strips come with an adhesive or double-sided tape already applied, so that’s the easiest installation method. However, Dan Belanger, master electrician and co-owner of 4Wire Electrical, cautions to stay away from lower-quality “LED ‘tape’ because it never sticks properly and will come loose eventually.” For the best installation experience, you can use LED light strip clips or look for strips that use 3M double-sided tape. If you’re installing a light strip that uses an inferior adhesive, you may consider applying 3M tape right on top of the existing adhesive. Then you can use the 3M tape to adhere your light strips to the mounting surface.
