They have a built-in mechanism that will conflict with a wall-mounted dimmer, causing the bulb to flicker, hum or simply not turn on. It’s also important to remember that smart bulbs are not designed to work with dimmer switches. Furthermore, to gain maximum benefits from a DALI system, all your light fittings should be independently wired, meaning that retrofits, while possible, are certainly more complex. Certain fittings require dedicated control cabling alongside power cables between fixtures, such as the DMX and DALI options. Once purchased, they’re extremely efficient to run, which should offset the initial higher cost.Įase of installation is another factor to consider, especially if your lighting project has a tighter timeframe and budget. For example, a DALI network arguably provides the best user experience, but the advanced technology that facilitates this can come at a higher price than other more established solutions. The driver must be designed to understand and interpret the signalling by the dimming device for dimming to occur.Īnother decision you will have to make will involve finding the balance between cost and control. This is due to the complex circuitry of the LED’s built-in driver.Īlthough it is the driver which dictates whether an LED product will dim, the driver’s performance largely depends on its compatibility with the dimming device. If a LED bulb is used with an incandescent dimmer switch, the bulb may only work at full brightness, may hum or flicker at certain levels or may even not turn on at all. Unlike incandescent bulbs, which dim indiscriminately, LEDs either dim or they don’t. In many cases, existing dimmer switches don’t work well with newer LED bulbs. Even the most experienced electrician or specifier may have trouble remembering which dimmer switch is best suited to your dimmable led light fittings. The main issue to be aware of is compatibility. However, now that there are so many options, there are some things that you’d be wise to consider before making a final decision. The innovations we’ve seen in dimmable led lights means that there’s now a workable solution for everybody, and you’ve never had more control over the brightness, colour and ambience of your lighting design.
