I have had a genius idea...
I mentioned I wanted some ceiling-wash tube lighting for the daughter's bedroom... After considering cornice (trough) lighting, I have come up with a better idea:
2 foot twin T8 fitting, HF ballast, fairly cheap, mounted in two key places on ceiling. Hanging by fine chain/wire from ceiling about 15-20cm down, and parallel-plane to ceiling is a flat sheet of white transluscent acrylic (or similar), about 1m x 0.6m, say 5mm thick so it will hang by 4-6 wires/chains at the corners. Has to be easy to unhook and clean because it will become a little bug(ger) trap.This will act as a part diffuser and part reflector allowing some light through and a lot of sideways wash onto the white ceiling.
This is *secondary* lighting for use in dark days, winter etc - not for getting up to, she will have a regular dimmable lamp for that. T8 (or even T5( tubes give me inexpensive fittings and a massive choice of tube colour- temps with decent efficiency.
So all I need to complete my plan is a way or machining place to get nicely shaped plastic sheet. Simulations with sheets of white paper held under a tube suggest this will be a good method.
Fancy case could be long ovoid. Simpler would be a rectangle with strongly radiused corners.
So I could either jigsaw it, then sand and somehow polish the edges. Not sure how to do that - but it needs to look totally pro and not like it's been hacked out by a jigsaw!
Or find some prototyping type place that can laser/water/CNC [1] cut the stuff in small runs. [1] Whatever leaves a clean edge.
Any ideas?
If this works, I am tempted to deploy in the two hallways too.
