Dimmable led9/16/2023 ![]() ![]() When LED drivers are first switched on, they draw a large amount of current for a very short time, until the capacitors inside them have charged. But it’s not necessary to worry about this as the Varilight V-PRO dimmers we recommend for all our LED Panel TRIAC dimmable drivers are compatible with both Leading Edge and Trailing Edge drivers. Mains dimming can be split into two types – Leading Edge and Trailing Edge. Mains dimming is achieved by switching off the power for a period twice in every wave, one for each cycle of current. As the current from the mains is alternating, switching from positive to negative every cycle, there are 100 cycles of current per second: 50 positive and 50 negative. That means this wave is repeated 50 times a second. The power from the mains in the UK comes in a wave with a frequency of 50Hz. Since our eyes cannot process the rapid switching, our brain interprets this as a steady, dimmed light source. The light is on and off at full power, but less light is delivered in total compared to if it was on the whole time. The result of this rapid switching is that less power is available to the light as the power is off for part of each second. It does this by switching the electric current on and off several times a second. Mains dimming works by chopping up the electrical signal from the mains. They have a knob you can twist anticlockwise or clockwise to decrease or increase the light output and push in to switch the light on and off. Mains dimmers tend to be rotary and are what you would find on a wall in place of a light switch. This will be familiar to many people, as it’s the method generally used in homes. Once that’s all sorted, it’s simply a case of taking a look through our dimmer range choosing your dimming method. Most LED panels are sold with a non-dimmable driver, as a dimmable driver must include more electronics which adds cost. When it comes to introducing dimming to your lighting setup, make sure that the LED panel, or more specifically the driver, is dimmable. But by following our guidance, dimming LEDs can work for you and become a great way to make even bigger energy savings and control your lighting environment. But your dimming module’s compatibility with LED bulb determines if and how well the system works, so be aware of your dimmer manufacturer’s requirements.Dimming LEDs is not as simple as dimming incandescent bulbs. While LEDs are generally priced higher than incandescent ones, they cost less to operate and don’t have to be replaced near as often, saving you cash over the lifetime of the bulb. Light-emitting diodes (LED), which use 75% energy and last 25 times longer than traditional incandescent bulbs, are another popular option. Florescent lights are commonly not dimmable due to the cost of dimmer-compatible ballasts, while compact fluorescent lights (CFL) that are fitted with their own ballast and standard screw bases are (check the manufacturers’ instructions to make sure). Like adjusting the water pressure on a facet, incandescent bulbs or lights with filaments are the easiest to dim (it’s a matter of lowering the power supplied to the filament using the dimmer switch). ![]() There are as many dimmer-compatible light bulbs available for sale as standard bulbs, with variations in type, wattage, size, style and color of lighting. ![]() Light bulbs are clearly marked as dimmable or non-dimmable on their packaging or ordering website. While installing a non-dimmable bulb in a dimmable circuit may cause damage to the bulb or circuit, a dimmable bulb in a non-dimmable circuit will work just fine - it will just run at an unadjustable 100% output. To utilize this type of lighting, you must have a dimmable light switch installed and compatible light bulbs. Dimmable lights support a reduction in energy consumption and prime mood lighting in your home. ![]()
