You may have medium to long term problems because the extra heat may affect susceptible parts. Sorry I can't be more specific than that. > > 2.

Dimmers are usually rated by the power (wattage) they can control. You may find you are limited by the amount of current you are allowed to draw from a household outlet. In the UK (240Volt) this is 13amps. Your setup would draw about 4amps here. There, it will be more like 9. Don't use a wind-up extension without pulling all the wire off the reel. <voice of experience> You can start quite an exciting fire due to inductive effects melting the insulation. </voice of experience> Can't help you with the rest. mike ----------------------------------------- Email sent from www.ntlworld.com Virus-checked using McAfee(R) Software Visit www.ntlworld.com/security for more information
