What are the different types of LED strip lights?
SMD Strip - Surface Mounted Device LED Tape
Adopts SMD LED package, common models are SMD 2835, SMD 5050, SMD 3528, etc. These splice LED strip feature high brightness, high energy efficiency and good heat dissipation, and are widely used in home and commercial lighting.
SMD 2835: The individual strip 2835 size is small, but with high energy efficiency, it is suitable for scenes that do not require high brightness but want to save energy, such as cabinet lighting, bedroom background lights, etc.
SMD 5050: each LED chip consists of three independent lamp beads, high brightness, can be used for colourful RGB strip, suitable for stage lighting, entertainment lighting.
SMD 3528: Moderate light efficiency, suitable for indirect lighting or auxiliary lighting, such as ceiling light trough, step lighting, etc
Advantages: SMD light bar has good heat dissipation performance, and different models can be selected according to the lighting needs of the appropriate light effect and power.
COB Light Strip -Chip on Board LED dotless LED strip
COB Light Strip adopts high-density encapsulation technology, which makes the light more even and without visible light spots, and is suitable for high-end lighting needs, such as architectural decorations, photographic lighting and so on.
Uniform light effect: As the luminous surface of COB LED tape is continuous and dense, there is no light spot problem of traditional SMD strip, so the lighting is more uniform.
High colour rendering index (CRI): COB super bright LED tape usually provide higher colour rendering index (CRI>90), which makes the lighting environment more natural and is suitable for high-end display lighting, such as jewellery shops, museums, photography studios, etc.
Energy saving and heat dissipation advantage: COB strips are more energy efficient, while the heat dissipation is well-designed so that they have a longer life span and can maintain a stable brightness over a longer period of time.
Applicable Scenarios: Widely used in commercial window lighting, art exhibition lighting, professional photography lighting arrangement, etc.
Neon LED Strip
Wrapped with flexible silicone material, soft and even light, excellent waterproof performance, suitable for outdoor decoration, advertising signboards, architectural contour lighting, etc.
Highly flexible design: Neon bendable strip lights is encapsulated in silicone or PU material, which allows it to be bent into various shapes, suitable for complex decorative needs, such as customised fonts and patterned lighting designs.
Waterproof: Many Neon light strips reach IP65 or even IP67 waterproof rating, which is suitable for outdoor environments, such as building facades, outdoor signboards, and landscape lighting.
Uniform light emission without light spots: Compared with traditional SMD strips, Neon strips make the light softer and more uniform through the full wrapping design, avoiding blinding glare.
Multiple colours available: Different colours such as monochrome, RGB, RGBW are available for dynamic lighting design, such as bar, KTV, shopping mall decoration.

LED Strip Accessories
Essential accessories include connectors (straight, angled, or solderless clips) for joining strips, waterproof terminals (2-pin or 4-pin) for secure wiring, and adhesive-backed clips or channel retainers for mounting. For extended installations, extension cables (2-core or 4-core in 1m/2m/5m lengths) help bridge gaps between strips, while heat shrink tubing provides waterproofing for soldered connections.
Power Supply/Controller
A constant voltage power supply (12V/24V, 60W/100W/200W) is required to safely power LED strips. Controllers like wireless remotes, Wi-Fi/Bluetooth/Zigbee modules, or DMX/PWM dimmers enable color adjustment, dimming (0-100%), and programmable lighting scenes. Compatibility depends on whether the strip is addressable (e.g., WS2812B, SK6812) or non-addressable. Built-in safety features like overload and short-circuit protection prevent damage to the system.
LED Profile
LED profiles, typically made of aluminum, plastic, or silicone, house and protect the strips. They come in surface-mounted, recessed, corner, or suspended designs for versatile installation. Sizes vary (e.g., 10mm×10mm, 20mm×20mm) to accommodate different strip widths, while diffuser covers (clear, frosted, opal, or prismatic) soften light and reduce glare. Accessories like end caps, mounting brackets, and screws ensure a polished, secure setup.
Cutting and Connecting Compatibility
Different types of LED strips may have different cutting and connecting requirements:
Single-colour LED stripe usually have one cutting point for every 3-5 LEDs, while RGB strips may require more complex wiring.
After cutting, ensure that the chosen connection method (soldered or unsoldered) is compatible with the strip to ensure electrical stability.
How the LED strip lights cut to size？
Identifying the Correct Cutting Points
Most LED light strips are marked with cut marks (usually scissor symbols) at specific intervals, these are safe cutting points to ensure that the circuitry is not damaged.
Tools Required for Precise Cutting
In order to get a clean cut and avoid damaging the 5 metre LED strip, the following tools are required:
- Sharp scissors or hobby knife: to ensure precise cutting without damaging the circuitry.
- Tweezers: For removing excess solder or adjusting wires.
- Electrical tape or heat shrink tubing: to protect cut ports from short circuits.
Precautions to Avoid Damage
Disconnect power before cutting:
Make sure the LED tape is unpowered to avoid the risk of electric shock.
Use the correct cutting tool:
Avoid using blunt knives or pliers to avoid damaging the circuit board.
Protect cutting ports:
Use proper insulation to prevent short circuits or oxidation.

FAQ
What is a soft LED strip?
A flexible, adhesive-backed lighting strip with embedded LEDs. It bends easily for curved surfaces, ideal for accent lighting, decor, or task lighting in homes, cars, or commercial spaces.
How do I install a soft LED strip?
Peel and stick the adhesive backing to a clean, dry surface. Ensure proper alignment before pressing firmly. Use mounting clips for extra security in high-temperature areas.
Can I cut soft LED strips to fit my space?
Yes! Most have designated cut points (marked by scissor icons). Cut only at these points to avoid damaging circuitry.
Do soft LED strips come with adhesive backing?
Most include 3M adhesive, but quality varies. For heavy-duty use, add mounting clips or stronger tape.
What power supply do I need?
Typically 12V or 24V DC. Match the strip’s voltage rating. Use a compatible driver/transformer and check wattage requirements for longer runs.
Are soft LED strips waterproof?
IP20: Indoor use (non-waterproof).
IP65: Splash-resistant.
IP67/IP68: Fully waterproof for outdoor/pool areas.
Can I change colors or control brightness?
Single-color: Adjust brightness with a dimmer.
RGB/RGBW: Use a controller for color changes, effects, and brightness. Some work with apps/voice assistants.
Do soft LED strips overheat?
Low-voltage strips rarely overheat if used properly. Avoid covering them or running in confined spaces. Use aluminum channels for heat dissipation in long installations.
How long do soft LED strips last?
Typically 30,000–50,000 hours. Lifespan depends on usage, heat management, and quality. Higher-grade chips (e.g., Samsung, Epistar) last longer.
