Lxfree lights seems small6/27/2023 ![]() The problem is worse on older lighting circuits and longer switch runs such as in two or three-way switching arrangements and it relates to how lighting and switch wiring is routed. In this case, the cause was stray capacitance on the switch wiring and this is likely to be the issue for most readers. This time the effect was more noticeable, and because it was in a bedroom, less desirable. I came across the problem again today however after converting an R50 fitting from incandescent to LED operation. There have been no ill effects over the past nine years and these lamps continue to work just fine. I did find it curious that when switched off, some of the LED elements in these lamps continued to glow dimly. LED lamps were in their infancy back then and these cluster lamps aren't great, but they're only lighting a small space and at a paltry 1.3W each they've already saved a sack load of energy over the 11W CFL fitting that was there before. I first noticed the 'glowing when off' issue after I fitted three LED lamps in my home's entranceway back in 2005. I can think of four reasons for this phenomenon and I have a potential quick and dirty fix for the most common cause. That said, one oddity is that they sometimes glow when off. Modern LED lighting is great. Bright, clean and a fraction of the running cost of incandescent lighting such as halogen or tungsten lamps.
