Do LED Dimmers Save Power? Here's What You Need to Know

If you’re using dimmable LED lights in your home, you might be wondering: does dimming actually save power? The short answer is yes—but only if you’re using the right kind of LED and dimmer combination. In this post, Greenled NZ breaks down how LED dimmers work, when they save energy, and what to look for.

How LED Dimmers Work

Unlike traditional incandescent dimmers, which reduce brightness by wasting electricity as heat, modern LED dimmers adjust the power flow to your LED bulbs using electronic control. This means they lower the brightness and use less energy at the same time—as long as both the bulb and dimmer are compatible.

When Does Dimming Save Power?

Dimming an LED light reduces its power consumption proportionally. For example, if you're dimming your LED to 50% brightness, you're typically using around 50% of the energy too. This is one of the easiest ways to lower electricity usage without sacrificing style or function.

Keep in mind, the actual savings can vary depending on the dimmer model, the number of lights on the circuit, and how often you dim. But the result is always better than running full brightness 24/7.

Tips for Choosing the Right LED Dimmer in NZ

• Check compatibility: Only use dimmable LED bulbs with an LED-compatible dimmer switch. Not all dimmers work with LEDs! You can find a wide selection of compatible dimmable LED downlights at Greenled.
• Use SAA-certified products: All Greenled dimmers and LED bulbs are SAA certified and tested for NZ electrical standards.
• Choose the right brightness: 3000K warm white LEDs are perfect for cozy living spaces. Use dimmers to adjust for mood and time of day.
