I’ve read through the excellent post on using dimmable LED bulbs on various dimmers and couldn’t find the info I needed so deciced to start a new post which is specifically for the ACT ZDM230 z wave dimmer (two switch), although I suspect the single switch dimmer form the same range is identical except for a bit of circuitry and a an extra bit of moveable plastic on the front.
So, I’ve tried some dimmable 5W LED GU10 bulbs from the “Long Life Lamp Company” (labelled GU5WLEDWW) on this switch, with an additional loading of around 160 watts from incandescents on the same circuit, so it shouldn’t be a load problem, and they flicker and shimmer something awful when you turn the brightness down. Even on full power they still flicker when you look at them with your peripheral vision. They are supposed to be dimmable on a halogen dimmer and are rated equivalent to a 50W halogen at 3000k colour temp.
They made averyone feel ill when I switched them on so they’re going back to the shop.
Has anyone had any good experience with dimmable LEDs on this switch?
Thanks
I tried some dimmable LEDs from Lustrum Lighting labelled EN62471 with 3 times 2 Watt LEDs in also labelled warm white but much closer to tungsten than the last ones. These flicker noticeably less and, whilst they still do flicker at low levels (in peripheral vision) it is much less annoying (no one is feeling sick or dazed!) and not noticeablefrom the light cast.
I’ll be keeping these in as task lighting and trying some Phillips branded ones later next week and will let you know how I get on. I’m relieved since I’m kind of stuck with the ACT dimmer switches, since nothing else is affordable in the UK.
As an aside, don’t know if I mentioned it previously but the switches are not reliable once you starting using the extra groupings (i.e. double clicks to control devices) but have so far performed flawlessly with single click operations.
I’ve got some of the switch only versions (ZTM230) with no dimmer circuitry to try out soon and am hoping they work similarly although I’m intrigued to see how they’ll show up in Vera, as they don’t have a device in them that can be controlled by Vera but are just remotes.
