Why are my 2-way switch bulbs flickering?

Depending on how a 2-Way Switch has been wired by the electrician, sometimes it can cause LED and CFL bulbs to briefly flicker every now and then while the switch is off. It may be anywhere from 10 to 30 seconds between flickers, and the flicker may not be very bright, but it is not ideal nonetheless. Our engineers have tested and reproduced this scenario and have come up with the cause and a very simple solution to the problem. Click here for a full explanation and solution to this issue.

Can I get dimmable LED bulbs?

Dimmable LED bulbs are not that common, and there are several reasons for this, including the higher cost associated with dimmable capable LED drivers, and the larger physical size making them difficult to fit into smaller bulbs such as MR16 bulbs.

However, one of the main reasons is because with current dimming technology it can be quite difficult to match dimmable LED bulbs with commonly available dimmers (such as mains leading and trailing edge dimmers available from electrical wholesalers) that are typically found in homes. Many of these dimmers require a certain amount of electrical current to operate, and therefore require a minimum loading.

LED bulbs draw very little power, and because they have internal switch mode drivers they actually draw less power if they are dimmed. This means that many LED bulbs when driven from commonly available dimmers (such as Clipsal, PDL etc) will flicker at low brightness, or will fail to turn on.

The engineers at LEDstuff are working hard to bring suitable dimmable products to our customers. We stock the Kiwi Electronics K004U Universal Dimmer as we have found it is more reliable with LED products than other available dimmers, and we fully test dimmable LED products before advertising their dimming functionality. If you are looking for dimmable LED products, please feel free to contact us to discuss your requirements.
