Hi Everyone:
I did a quick search of this site and have discovered several posts reporting trouble with Megaman Dimmerable CFL GU10 lights.
We have installed 14 of the warm 11W GU10s here in ceiling downlights. The bulbs came with the light fittings (Flameguard CF409s). There are three circuits: One with 6 lights and two with 4 lights each. The dimming switches we used were recommended on the Megaman site. We calculated the load on each dimming switch as described on the Megaman site and got the appropriately rated switch. They were always started at full power, allowed to warm up for a few minutes and then dimmed if required.
Since installation in the autumn of 2009, 13 of the lights have failed. Not dramatically, or anything, they just fail to come on one day. After about 4 of them failed, we took off the dimming switches and replaced them with normal on/off switches. That didn't seem to stop them failing. They were advertised as being good for 10,000hrs, but there is no way that limit has been reached.
We also installed a fourth circuit at the same time as the three dimmerable circuits. This circuit had three normal 11W CFL GU10s. So far they have worked fine.
Just wondering if anyone else has had a similar experience and if anyone can see if we have done anything wrong.
Cheers!
