These Enviro LED strips are intended for surface mounting, in any direction. LEDs consume less energy and run at a cooler temperature. These strips are ideal for accent lighting under or over any cabinet, shelf or display. They are also an extra value to add to any workspace, workshop or even the garage. Due to their very low profile, they are very easy to hide even in shallow structures. Multiple fixtures can be linked together, up to 3 with the included driver. They comes in three different length, 12, 24 and 36 inches to best fit your spaces.
