![]() ![]() Dead travel - When the dimmer is adjusted there is no matching change in light output (light may not dim to acceptable level).Drop-out - No light output at the end of the scale.Flickering - Lamps will flicker (can also occur if a non-dimmable lamp is used).Some of the issues that may occur when a dimmer is incompatible with an LED lamp are: Low-voltage transformers as used with MR16 12V spotlights also add to the complexity LED currently have a lower dimming range than a filament lamp – LEDs currently dim down to about 10% of the total light output whereas filaments may go down to 1-2%. Since there are a huge number of possible combinations of lamps and dimmer, it is very difficult to produce an LED lamp that works in all dimming environments. Overall the LED dimming performance is regulated by the capability of the LED driver/chip and the compatibility of the dimming circuit. The dimming experience can be different with LED. Dedicated LED dimmers have a very low minimum power rating. A 60W filament lamp may use a dimmer that has a minimum load of 25W the replacement LED has a power rating of 6.5W - below the level required by the dimmer. The driver in dimmable LED lamps may work with many types of dimmer but not all, for instance LED lamps tend to work better with trailing-edge dimmers rather than leading-edge dimmers, but an existing dimmer may have a minimum load that is too high for an LED lamp, e.g. So when using new LED lamps with existing dimmers there is a matching of old technology with new which can be challenging. ![]() resistive leading-edge and trailing-edge and electronic). They are many different types of dimmers installed in homes and offices of various specifications (e.g. Furthermore driver specifications are not uniform across the LED industry. An LED bulb is a solid-state product that has built in circuitry (called a driver) that takes high-voltage AC input current and converts it to low-voltage DC current to drive the LEDs. LED lamps on the other hand are low-power and more complex. Most dimmers installed today are designed to be used with high-power circuits to drive traditional filament lamps which were all quite uniform and dimmable by just a voltage change. Integral lamps are clearly marked as dimmable or non-dimmable on the packaging and on the lamp. ![]() You should NOT use a non-dimmable lamp in a dimmable circuit as it may cause damage to the lamp and or circuit. You can use a dimmable LED lamp in a non-dimmable circuit. You will need to choose the correct type for your lighting circuit.ĭimming LED lamps can save energy and changes the visual appearance and mood of your space. Many retrofit LED lamps are sold in two versions dimmable and non-dimmable. ![]()
