Same here Ken.

We tried single 8W then double 8W - both made heaps of noise through the car radio - especially when in a distant location, where the radio signal is weak.

I was convinced that the interference was coming back through the 12V wiring so we bought a stand alone Arlec 20W rechargeable - but it does the same - noise!!! It is a much better light than the smaller units though.

Then I came across some Nelson 12V/12W compact fluro bulbs. These physically look like a normal 240V high efficiency compact fluro - and are available with the normal bayonet or edison screw fittings.

WOW - much better light than the Arlec 20W fluro and NO NOISE!

I bought mine from Bunnings and used the bayonet type because a HPM switched batton socket is available for bayonets but not Edison Screw types. This makes it easy to make up a switched lead.

Have a look at:

Then look in the 'Garden Lights' section and scroll down to the 'ELV' (Extra Low Voltage) section - there are two colour temperatures available - Natural or Warm White - both available in either bayonet base or Edison Screw base. You will note that they have built in 'Radio Interference Suppression'.
Print off the page and take it to your local lighting specialist distributor.

Current draw is 1 amp and they run cool.

We now have three of them!
