Hello, I have a 220 Volt outlet in my garage for my Arc Welder. Is it possible to use that for my 1000 Watt growlamp. Will the electricity bill be cheaper to run the 220Volt???. An electrician told me it's cheaper to run my household washer and dryer with 220V instead of through normal 110V. Also, will I have to buy a different plug and wire for my growlamp to use it with 220Volt, Thanks CW.
