I've seen them in one of our Bunnings hardware stores here, but they are 12v and fit halogen sockets...must be a market for coloured downlights? I think they were low powered..5W maybe? And I would guess they were cold cathode too, given the thickness of the tube was probably only 4mm or so.
How about the indicator coloring paints of yesteryear, or food coloring dyes?
Thanks -- That's a good idea, and one which hadn't crossed my mind.
What sort of application are these being used for?
They're actually linked with the very long-running saga of the mobile home and PV/wind system in this thread .
We're putting the regular white CFLs in most of the light fittings (spiral types due to restricted space), but the owner wants a couple of colored bulbs for decorative lighting (alcoves etc.), but being on the inverter system wants to keep the loading as low as possible.
I think he wants a couple of red or orange bulbs for the backlighting in the gas heater too.
