LED Strip Light Power Supply - Hard Wired (Dimmable)

These 24V TRIAC Dimmable power supplies work with linear LED ribbon strip or other constant voltage LED luminaires, suitable for indoor use only.

A 20% buffer is recommended when calculating your required power supply wattage to avoid overloading.

Here's how to calculate the correct power supply wattage for your COB LED installation:

Basic Formula: Total Watts Needed = (Watts per meter × Total meters) × Safety Factor

Step-by-Step Calculation:
- Determine your total length

- Measure how many meters of COB strip you'll be installing
- Calculate base power requirement

- Multiply: watts per meter × total meters
- Example: 9W/m × 5 meters = 45 watts
- Add safety margin (20-30%)

- Multiply your base requirement by 1.2
- Example: 45W × 1.25 = 56.25 watts
- Round up to next available power supply size

What is an I.P Rating

IP ratings tell you how well protected your power supply is against dust and moisture - crucial for choosing the right unit for your installation location.

IP Rating Breakdown: The two digits after "IP" indicate protection levels:

- First digit = dust protection (0-6 scale)
- Second digit = water protection (0-8 scale)

IP20 Power Supplies:

- 2 = Protected against objects larger than 12mm (like fingers)
- 0 = NO water protection whatsoever

Best for: Indoor use only in completely dry locations

- Inside cabinets, closets, electrical panels
- Residential indoor installations
- Office environments
- Anywhere moisture will never be present

IP67 Power Supplies:

- 6 = Completely dust-tight
- 7 = Protected against water immersion up to 1 meter deep

Best for: Outdoor and wet location installations

- Exterior building lighting
- Pool/spa areas
- Bathrooms and kitchens
- Basement installations
- Marine applications
- Any location with potential moisture exposure

Key Differences:

IP20:

- Lower cost
- Better heat dissipation (ventilated)
- Smaller, more compact
- Must be installed in protected locations

IP67:

- Higher cost
- Sealed units (may run warmer)
- Larger/bulkier due to weatherproof housing
- Can handle rain, splashing, temporary submersion

Choosing the Right One:

- Always use IP67 if there's ANY chance of moisture contact
- IP20 is fine for completely dry, indoor-only installations
- When in doubt, go IP67 - better safe than dealing with failed power supplies
