The product was exactly what I was looking to replace the defective neon lights with a flat screen. The tape is 8 mm wide. One side of the tape is self-adhesive and the other side is coated with a transparent and flexible material which gives it a good insulation. White is really cold and high light the intensity. As shown in the ad the product does not come with a power supply. Despite this, the tape has a very good price / quality ratio.
