(oops, originally I wanted to open this in Technology :s )
I thought knew the basics about fluorescent lights, like for example what it means when they need a while to turn on. But the lighting in my apartment has me scratching my head.
There are 3 light bulbs (fluorescent, but small/round) in one “holder”, plus another light bulb in a seperate holder on the other side of the room.
Normally (until recently) when you press the light switch for certain numbers of times, it switches between different states:
- 2 + 1 lamps on
- 0 + 1 lamps on (first 3 lamps have some kind of very dim extra light in the socket on, though)
- 3 + 1 lamps on
- 1 + 1 lamp on
And if, after waiting a few seconds, you press the switch once, everything goes off.
Weird enough logic for me, and seems overkill anyway… but now a while after turning on (a minute or so, seems getting shorter to just seconds now) you hear a slight “click” sound and the lighting stuff switches to the mode 2) I described above. That is, unless you select mode 3) - in this case all lamps will be on indefinitely. So only modes 1) and 4) are “broken”.
The fact that 3) works OK makes me wonder if maybe it’s not simply a too aged light bulb, but instead something else. My hope is that someone knows this kind of “light control logic” and can comment on where to have a look…
