The phosphor discolours just the same as normal tubes. Quality does vary between brands and older tubes are generally also better made than those coming out of China these days.

RFI is an issue these days because of self regulation. Manufacturers just put compliance plates on their appliances declaring that the product meets certain standards. Hardly anyone understands the issue so the declarations generally do not get contested.

Photos sent by members I the last couple of days will be published tonight.

I think the most bayonet double adaptors I ever had at one time was four - a mix of the type pictured and the earlier 'Y' type where both sockets are off at an angle.

I'd like to move to LEDs as soon as feasible, but there are a couple of problems with currently available types that have to be backwards-compatible to our 240v fittings.

The electronics to step down from 240v, rectify and smooth the DC can generate quite a lot of heat in base - as noted by Chris at to top of this thread.

Some of the power components can also put out a lot of RFI.

The light emitted is often less diffused than it claims to be, since every LED is is basically a uni-directional emitter. If find the quality of the light can play weird optical tricks with my eyesight, or perhaps it is my glasses. I tried using a gooseneck LED lamp for workshop purposes and it was hopeless for close work. Multi LED lanterns are fine for more general lighting.
