LED lighting transformers are devices that provide the low-voltage direct current (DC) required for LED lamps. LEDs typically operate on 12V or 24V DC, and these transformers convert standard mains electricity (220V AC) into a voltage suitable for LEDs. When selecting a transformer, the following features should be considered:

1. Power Capacity (Watt)

• The total power of the LEDs you will use (e.g., 5 LEDs x 10W = 50W) should be less than the transformer’s capacity. It's recommended to choose a transformer with at least 20% extra capacity.

2. Voltage Output

• Choose a transformer compatible with your LEDs' operating voltage (12V or 24V).

3. Type

• Constant Voltage Transformers: Commonly used for indoor applications and decorative LEDs.
• Constant Current Transformers: Preferred for professional LED systems operating at a specific current.

4. IP Rating

• For outdoor use, water- and dust-resistant models (IP65 and above) are required, while IP20 is sufficient for indoor use.

5. Dimmable Feature

• If you need to adjust the light levels, opt for dimmable transformers.
