What is Dimmable Lighting?

Dimmable lighting allows users to adjust the brightness of their light fixtures to suit their preferences or the needs of their space. This feature offers flexibility in creating the perfect ambiance for any occasion.


One of the key benefits of dimmable lighting is its ability to conserve energy and extend the lifespan of light bulbs. By reducing the light intensity, energy consumption decreases, leading to lower utility bills and a smaller carbon footprint.

Use Cases:

Dimmable lights are versatile in use, enhancing the functionality of various environments. They can create a soft, intimate atmosphere in dining and living areas or provide bright, focused light in workspaces and kitchens, adjusting seamlessly to the task at hand.

Driver Included

What does "Driver Included" mean?

"Driver Included" indicates that an LED fixture comes with an integrated driver, which is a device necessary to convert incoming AC power to a suitable DC voltage for LED operation. This feature simplifies installation and ensures compatibility between the LED and power source.


The key benefit is convenience and assurance of performance, as the included driver is specifically designed to work with the corresponding LED fixture. It eliminates the need for separate purchases and compatibility checks, facilitating easier and more reliable setups.

Use Cases:

This is particularly beneficial for DIY projects, retail lighting installations, or anywhere that LED lighting is employed, as it streamlines the process.

Dimmable Options Explained:

0-10v: A 0–10V dimming driver sends a low DC voltage signal to the fluorescent ballast or LED driver. The lighting changes as the voltage is varied. So, at 0v the light will dim to 0% and turn off. At 10v the driver is operating at 100% and the light will be fully on. A 0-10v dimming system can operate 10 LED products per controller.

DALI: This panel comes complete with a TC Jolly Dali dimmable LED driver, enabling this panel to be dimmed via a PC or Wall Interface system. It can be dimmed as a group or singular. This also enables the fitting to work on a corridor function and have options for pre-set scenes.

DSI: The driver receives a digital signal which tells it how to respond. The advantage of digital dimming is that fixtures are addressable. You can also have many more different levels of light output.

TRIAC: TRIAC Dimming otherwise known as phase cut dimming, TRIAC dimming acts as a high-speed switch and is used to control the amount of electrical energy passing to the lamp. A 'trigger' dictates what point the device starts to conduct the electricity, the quicker the switch reacts the more power is let through and the later it reacts the less power, resulting in the dimming of the bulb. TRIAC Dimmers include leading and newer trailing edge switches.
