What Wattage rating for lamp limiter?

[pwdrive]

That's a neat and well thought out presentation Lawrence.

Well spotted.

David,yes, I've been trying to find on the web some plotted curves for various voltages versus current/resistance when applied to a 230/240 volt filament bulb, didn't find anything on my first trawl but that link I posted came up, from that it might be able to establish a general prediction curve for higher and lower wattage bulbs not covered in that link, why?...dunno, I just find some odd things interesting.
