LED Power Supplies
The power supply (LED driver) is the heart of any LED installation. For engineering projects, we recommend Meanwell brand drivers for their proven reliability, global certifications, and 5-year warranty. Choosing the right power supply ensures stable operation, long lifespan, and safe performance.
- Meanwell HLG series: IP67 waterproof, ideal for outdoor bridge/facade projects
- Meanwell LRS series: Indoor use, slim metal case, cost-effective
- Meanwell ELG series: IP67 with dimming function (0-10V, PWM, DALI)
- Always use 24V drivers for engineering projects (safer, less voltage drop)
- Size the power supply at 80% load maximum for longevity

LED Controllers
Smart ControlControllers determine how your LED strips behave — from simple on/off and dimming to complex RGB color-changing effects and DMX-controlled architectural lighting scenes. Choose the right controller based on your strip type and project requirements.

Aluminum Profiles
Heat DissipationAluminum profiles (channels/extrusions) serve three critical functions: heat dissipation to extend LED lifespan, light diffusion for a smoother appearance, and physical protection for the strip. For engineering projects, always install LED strips inside aluminum profiles — this is an industry best practice.
| Profile Type | Mounting | Strip Width | Diffuser | Application |
|---|---|---|---|---|
| Surface Mount (U-shape) | Screw/adhesive on surface | Up to 12mm | Frosted / Clear | Under-cabinet, shelf lighting |
| Recessed (T-shape) | Flush into drywall/wood | Up to 12mm | Frosted | Ceiling cove, wall slots |
| Corner (V-shape) | 45° angle mounting | Up to 10mm | Frosted | Cabinet corners, display cases |
| Pendant / Suspended | Wire suspension | Up to 20mm | Frosted | Office, retail hanging lights |
| Floor / Ground | Flush with floor surface | Up to 15mm | Frosted (walk-over) | Stairway, pathway guidance |
| Wide Channel | Surface/recessed | Up to 30mm | Frosted | High-power dual-row strips |
Connectors & Mounting
AccessoriesProfessional connectors and mounting accessories ensure clean, reliable, and code-compliant installations. For outdoor projects, always use IP-rated waterproof connectors to prevent moisture ingress and ensure long-term reliability.

How to Calculate Power Supply Size
Choosing the correct power supply wattage is critical. An undersized power supply will overheat and fail; an oversized one wastes money. Use this formula:
Power Supply Formula
Strip: SMD 2835, 120 LEDs/m, 9.6W/m
Total length: 20 meters
Calculation: 9.6W × 20m × 1.2 = 230.4W
→ Choose Meanwell HLG-240H-24 (240W, outdoor) or Meanwell LRS-350-24 (350W, indoor with room to spare)
Voltage Drop Rule
For runs over 5 meters, always use 24V DC instead of 12V. Feed power from both ends for runs over 10m to prevent brightness drop at the far end.
Thermal Management
Always install high-power strips (>14W/m) inside aluminum profiles for heat dissipation. Without proper cooling, LED lifespan can drop by 50% or more.
Safety Margin
Load your power supply to a maximum of 80% capacity (multiply by 1.2x). This extends PSU lifespan and prevents overheating in hot climates.
