Variables in strip lighting consist of colour, adhesives, and water resistance. Common chip placement within the tape allows light to emit away from the surface to which the tape is adhered (unless ‘side view‘ or ‘edge emitting‘, see below). Water resistant strip lighting is covered in a heat conducting epoxy to protect the circuitry from direct contact with water. The most common design differences are in how individual LEDs are controlled, specifically differences in color and whether or not each LED is addressable.[3]
LED strip lights typically operate on 12 or 24 volts of direct current from a transformer (driver). USB strip lights operate on the standard 5-volt direct current used by USB devices.[7] Any customizations require an LED controller to adjust brightness, colour, or individual LED activity. This can be done with an included controller or customized with a microcontroller.[3] Mains voltage LED strips are also available. These have the advantages of being usable in much longer single runs without a brightness drop along the length, but are less flexible and heavier due to higher voltage and current ratings and thick coatings for shock safety and high IP ratings in their intended outdoor positions, with limited cut points. No separate power supply is needed, although there must be a rectifier between the mains supply and the end of the LED strip.[8][9]
Strip lights are designed for both indoor and outdoor use depending on whether they’re water resistant. Since the strip is flexible and can be divided at any point between LEDs, it is extremely versatile and can be used in a number of installations. Outside of traditional lighting, strip lighting is extensively used in DIY projects or lighted clothing. The ability to power strip lights off of a USB device or battery pack makes them extremely portable. Examples include: Computer lighting, costume lights, toys, workspace lighting, monitor and display ambient lighting, and alcove lighting.[10]
