Jaffacree Posted January 13, 2015 Share Posted January 13, 2015 Hello,I have a dimmer that will every so often, when turning on the light, flash the LED's green and shut the light instantly off. I will then have to turn the light back on and it works just fine. Any ideas as to why this is? I am running 2.6 Link to comment Share on other sites More sharing options...
Cyknight Posted January 13, 2015 Share Posted January 13, 2015 Most likely overload, shut off for protection. Are these LEDs or CFL/Fluor Tubes? Link to comment Share on other sites More sharing options...

Cyknight Posted January 13, 2015 Share Posted January 13, 2015 Then I'm guessing these are the previous style switches? - Because on overload the new ones should go red (and would need a reset). LEDs have a very high initial rush potential - do you know the details on your lighting device (ie what generation, is it normal/ELV, is it in a multigang box, are there still tabs on the side) and what is the total wattage on the LED bulbs it's dimming.

Jaffacree Posted January 13, 2015 Author Share Posted January 13, 2015 It is a previous generation style normal switch. Single gang. (2) 9.5W bulbs so 19W total. The tabs should both still be in place Link to comment Share on other sites More sharing options...
Cyknight Posted January 13, 2015 Share Posted January 13, 2015 Mhh, well that should be well below the threshhold - however, you're also well BELOW the minimum wattage for those dimmers. Is it a major concern to swap those two out for incandescent or halogen (to test). I don't see how being below the minimum would cause the issues you see (would expect other issues though) - but it's something to start with. Wait - you say switch now - is it a switch or a dimmer?

Jaffacree Posted January 13, 2015 Author Share Posted January 13, 2015 Sorry, it is a dimmer. Ill try swapping out the LEDs for incandescent and see if that works. Like i said, its not every time I turn on the dimmer. Only some times... Link to comment Share on other sites More sharing options...
Cyknight Posted January 13, 2015 Share Posted January 13, 2015 Yeah I got that. If you can have those incandescent in for a few days or unitll the same thing happens - if it doesn't happen then, at least we know if it may have something to do with rush current or minimum current - be it bulb side or dimmer side. If it does, the issue would be with the switch (sorry - dimmer ). Link to comment Share on other sites More sharing options...
Jaffacree Posted January 14, 2015 Author Share Posted January 14, 2015 I replaced the trouble LEDs with lesser wattage LEDs, and so far so good. No issues as of yet. Moved trouble LEDs to another dimmer and no problems yet. Hopefully it works out Link to comment Share on other sites More sharing options...
Jaffacree Posted January 15, 2015 Author Share Posted January 15, 2015 So the trouble LEDs acted up again on a different dimmer. I now completely took these LEDs out and have different bulbs in for good. The bulbs were Cree 9.5w 2700k 800 lumen bulbs. Link to comment Share on other sites More sharing options...
CFUG Posted January 15, 2015 Share Posted January 15, 2015 I've had more troubles with LEDs in past 4 months. A few years ago, I started in replacing with LEDs and they worked marvelous against C4 dimmers but the color was not ideal. Now that the color temp. is about right, the new ones are flashing on/off and flickering randomly. Make no mistake, the C4 dimmers will handle the load of your LEDs- that's not the problem area. I would be more concerned if it were a switch but still not up against a few watts of LED. Cheap, cheap, cheap goods. I don't care what the box says, Cree, Phillips- all engineered to take your money now. Link to comment Share on other sites More sharing options...
Jaffacree Posted January 15, 2015 Author Share Posted January 15, 2015 I have similar Cree bulbs in all over my house, on dimmers and switches. This is the only bulb that has ever acted this way against a dimmer. Link to comment Share on other sites More sharing options...
