1、 Classified by voltage
Low voltage COB light strip
Voltage: 12V, 24V (common), 5V, 48V (rare).
Features:
High protection: Low voltage with no risk of electric shock, suitable for close range touch scenarios in households, cabinets, and bedside areas.
Sensitive device: Supports adhesive backing and light trough installation, with customizable length (generally no rated power supply required within 10 meters).
Long lifespan: Low voltage planning reduces circuit losses, with a lifespan 3-5 times that of high-voltage LED strips.
Usage: Home lighting (background wall, ceiling), car interior, commercial display cabinets.
High voltage COB light strip
Voltage: Directly connected to 220V mains power without the need for a transformer.
Features:
Length advantage: A single strip can extend continuously for tens to hundreds of meters, suitable for large-scale lighting.
Low cost: The price is affordable, but it emits eye-catching light, has severe flicker, and has a short lifespan.
High voltage electricity needs to be equipped with protective covers, and the location of the device should be kept away from human touch.
Usage: Outdoor advertising signs, construction and decoration, tooling spaces (such as mall ceilings).
2、 Classified by luminous method
Single sided illuminated COB light strip

Feature: When the light source is facing up or down, the light will converge.
Usage: Top lighting (such as ceiling concealed trough), light trough lighting.
Side illuminated COB light strip
Features: The lamp beads are placed on the side, and the light is scattered to both sides.
Usage: Advertising lightbox, letter light, narrow border light strip (such as display cabinet backlight).
Double sided illuminated COB light strip
Features: It emits light from both the front and side, with even and no dead corners.
Usage: Design decoration lighting (such as stair handrails, glass partitions).
