Such compatibility lists can be found primarily from brand manufacturers. Such lists can be found in a search engine of your choice, for example with the search term dimmer compatibility list manufacturer name. The results are summarized in the compatibility list. The manufacturer is therefore testing the LED lamp with LED dimmers widely available on the market. But even today there is still no hundred percent guarantee that a dimmable LED lamp will function perfectly with any LED dimmer.įor this reason, some lamp manufacturers publish dimmer compatibility lists for their dimmable bulbs and luminaires. A too small dimming range or other side effects were the result. In the early days of LED technology there were big compatibility issues despite dimmable LED lamps and LED dimmers. Most LED lamps require a reverse phase control dimmer. The old dimmers are therefore mostly unsuitable for the new LED lamps. However, LED lamps represent a capacitive load. These are primarily suitable for resistive loads. The dimmers installed for older incandescent light sources work with forward phase control technology. In addition to various dimmer variants (rotary knob, touch dimmer, with remote control), these work internally with one of the following techniques: In addition to a dimmable lamp, a dimmer suitable for LED technology must also be used. If only one component in the entire chain (dimmer – transformer – illuminant) is not marked as dimmable, difficulties or defects are inevitable. Dimmable LED transformers also have a corresponding marking. Please note that both the LED lamps and the LED transformer must be dimmable. When using low-voltage LED lights, an LED power supply is required. Many online shops offer a sorting function where you can filter by dimmable lamps. The proportion of dimmable LED luminaires is slightly smaller. Especially for LED bulbs there is a huge selection of dimmable models. Whether an LED illuminant or an LED luminaire is suitable for use with a dimmer can be seen from the marking. Therefore, it is generally cheaper to pay the surcharge for dimming only for rooms where adjustable brightness matters (such as living rooms).ĭue to the complex internal structure, only LED lamps marked as dimmable should be operated on a dimmer. In most rooms (such as corridors, kitchens, bathrooms, cellars) it is not necessary to adjust the brightness at all. If all LED lamps were suitable for connection to a dimmer, LED lighting would be more expensive overall. Dimmable LED lamps are usually somewhat more expensive than non-dimmable versions. Why isn’t dimmable technology built into all illuminants and luminaires? The main reason is the higher effort regarding the internal electronics which leads to higher costs. The dimming of LEDs is therefore technically possible. This question arises after finding out that there is a large number of dimmable LED lamps on the market.
Just make sure that the lamp is marked as dimmable. Fortunately, consumers do not have to concern themselves with the technical details. The dimming process of an LED lamp is more complex than with old light sources. If this does not work without problems, sometimes the entire LED technology is demonized as not mature. However, this is primarily due to the fact that many people simply assume that LED’s can be dimmed just as easily as the old light sources. However, LED technology is much more complex and brings in some challenges.ĭimming of LED lights is one of the most common difficulties when converting to LED lighting. In the meantime, LED lighting technology has established itself and offers many advantages over the old light sources. These lamps could be easily operated with a dimmer. Old incandescent bulbs and halogen bulbs had an advantage in addition to all their disadvantages.
