I got a very rare incident when I switch my desk light on or off: This is not happening every time, but like 1/10 times. For example, I have my phone connected and switch off my light… Windows instantly plays the sound of a disconnecting/reconnecting USB device and iTunes starts syncing again.
My desk light uses an 11 watt fluorescent “Osram Dulux S” energy saving lamp. When I switch it on, it flashes two times before it’s permanent. It seems, as if this issue only occurs after the lamp was on a longer period, as I cannot reproduce it by switching it on and off multiple times.
The desk light was formerly connected to the same multi outlet socket, but right now it is a few meters away plugged in, but still in the same wall.
Could be, that my problem is a bit off topic, but I thought, that some people here might also know something about electronics ;)
I built this computer myself, but I made a lot time and precision to build it, in order to do everything correctly.
What might be causing this issue?
2The type of light that your desk light is could be important to the question. florescent , cfl, led , Incandescent? how many watts total it is and if it relies on a low-voltage or high-voltage transformer ? Like if it uses 12V bulbs? – Psycogeek – 2015-09-11T22:46:32.603
oh yes, sorry for forgetting about that: it's a 11 watts fluorescent energy saving lamp named "Osram Dulux S". When I switch it on, it flashes two times before it is permanent.
