Just to use as a quick estimation.... At 10 cent kilowatt hour, a 1,000 W bulb run at 10 hours a day for 30 days will cost $30. Sorry for the very basic numbers but I did not want to strain my brain too much.

I think I'm cheating by giving you all the answers without making you read but I enjoy helping out on the very rare ocassion I'm able. You can always read up as you go. :thumbsup:

Keep up the great work!
