  • Is the Phillips Dynalite system compatible with Filament LED Globes?

    Phillips Dynalite system struggles with LED filament lamps due to technology gaps and the fact the system is leading edge dimming which isn’t always compatible with LED lamps.

    To dim our Edison Filament LED lamps effectively without flickering you need a Dynalite DDBC120-DALI MultiMaster Dali Driver Controller with 1 dali loop and a Helvar 454 4x500W Leading/Trailing Edge Dimmer.

    The Dynalite DDBC-120-DALI must be connected to the existing Dynalite System using proprietary Dynet protocol and the Helvar 454 will be connected to DDBC-120-DALI output. The process and installation in not invasive or complicated.

  • Do LED globes dim the same way as incandescent globes?

    LED lamps have very different response to dimming than previous generations of lighting lamps. It is important to remember that the pre-set scenes of a lighting control system will need to be adjusted if a project has upgraded to LED lamps.

    LED lamps could also have a very different dimming curve to previous generation of lighting lamps. A lighting control system will need to compensate for LED dimming site effects such as:

    Dead travel this is when adjusting the dimmer channel output seems to have no relative effect to the LED lamp light output.

    Popping on a LED lamp may require a minimum level before it is able to start producing light. For some lamps this might be as high as 10%-15%.

  • Why are my LED globes flickering?

    When dimmed, LED lamps may become susceptible to a temporary or permanent flickering. Care in selecting the right lighting dimmer or controller for the desired LED lamp is important so the risk of LED flickering can be reduced. Sources of LED lamp flicker can come from a range of different locations and often at the same time, for example:

    • Mains supply instability.
    • Noise on the mains supply or dimming system.
    • Dimming system not loaded correctly.
    • Too many or to few LED lamps are being used per lighting circuit.
    • LED driver design.
    • Dimmer level set too low.

  • Why dim LED globes?

    As with any area in which artificial lighting is used, people like to adjust the lighting level to meet their needs and create a more comfortable environment. Allowing the occupants of an area to reduce the lighting level can help reduce glare when there is excessive lighting levels. By reducing eye strain in office or school areas occupants are more comfortable and better able to focus on the task at hand, allowing for them to be more productive.

    When dimming LED lamps, their power consumption is also reduced, producing further running cost savings. A dimmed LED lamp also produces less heat which will help increase their operation life and protects the investment an end-user has made into their LED lamps.

  • Dimming LEDs

    Not all LED lamps are dimmable, only lamps that have been specifically designed by the manufacturer as dimmable may be dimmed. Attempting to dim a non-dimmable LED lamp or using an incompatible dimming method will result in undesirable behaviour or complete lamp failure. Dimmable lamps may only be compatible with certain dimming techniques so it is important the correct method is used.

  • Are your light globes dimmable?

    All incandescent bulbs are dimmable.  All our LED globes are dimmable, however the the right dimmer needs to be used. Generally a Trailing Edge or Universal dimmer should be used for LED. We recommend a Clipsal Universal as a general starting point.

    Our current update to our 240V LED bulbs give much better dimming performance across a wider range of dimmer switches. Look for bulbs that are listed including Double IC deep dimming system in the specifications tab.
