Confirm your wall switch is good. Bad switches can be intermittent. Turn off the switch and take the tubes back out and put them back in making sure they're fully snapped in. It's worth a try. Don't go buy more, but if you have other new tubes try them. If the lights work for a period of time and go out on their own, that usually indicates an over-heating ...

If this is, in fact, a split outlet, you should be fine wire nutting the blacks and a black pigtail, the reds and a red pigtail, and you can connect the whites directly or wirenut them and a pigtail, as you prefer. You will need to break the tab connecting the receptacles on the hot side, at least (my guess is that they broke the hot tab and left the neutral ...

Often, electricians used ordinary black/red/green twin&earth for C but marked the black wire with red tape (to indicate "switched live") You seem to have something nonstandard, perhaps a spur (therefore missing B) without an earth to the switch? You'll have to use appropriate methods to determine what is what. See answer to similar old question ...

Bulbs nearing end-of-life. Ballast nearing end-of-life. The CFL in my office has been doing something similar for months - I just turn it on once a day and try to remember not to turn it off unless it will be off for hours. It's a normal failure mode for fluorescents. Buzzing and flickering not required.

Can't find that one. Another company's model that gives numbers (after looking more - MANY don't, which seems sketchy) claims 10mA @ 24v, or 0.01A x24V = 0.24W - less than 15, yes; Quite a bit more than 0.002, though. Whether it's actually worth buying (since you mention that it's expensive) would depend on how much you pay for power and how many hours it ...

Brightness: Professional lighting Designers use lumens per metre to calculate the amount of light that is needed for the room using software on a computer in which to do this. So measuring this is unlikely but as a guide 5w per metre (around 300lm) is for highlighting, 10w is bright enough to use as work light (around 600lm). Uneven light: You do not want ...

The "California Three-Way" could be wired similar to what you have shown. Fundamentally, it wires each wire of one three-way switch to the corresponding wire of the other; if the switches are in opposite positions, each switch will form a connection between the wiper and one other terminal, and thus the two non-wiper terminals will be connected. The ...
