Again I agree 100% with what your saying. I was taught in school that anything that causes resistance (ohms) generates heat and uses electricity. Like you mentioned even a extension cord has resistance and is a factor in power consumption. I don't claim know everything, but that doesn't mean that I just believe anything that anyone says either. If it doesn't make sense to me, I ask questions (sorry if that offends you willard3).

I have known about the Kill-A-Watt Meters for about two years now. I saw one on a show about being green, and decided to look into them. I still have not gotten one, but would like one because I would like to know just how much each appliance in the house is costing to run. I grow everything outside so hydroponic lighting is not an issue for me (at least now), but I may do some indoor growing in the future. I also know they are easy to get, I have seen them down at Home Depot and Lowe's, I just always seem to have something else to spend the money on.

And again what you say about Lumens is very true (I was only being sarcastic in my P.S.). But I agree that Lumens are essential to plant growth and photosynthesis, and even a form of energy in that regard. It's just not as a form of electricity as willard3 would have me believe. But simply just a measurement of preservable light (the key word being "preservable") to the human eye. I also know there are meters that will tell you the Lumens at the distance you place it from the light (I don't have one of those meters either). But for any indoor commercial growing operation that would be a must for cost efficacy.

P.S. When I retire, I plan on getting glaucoma so I can get one of those medical marijuana cards myself. It has been 20 years sense I have partaked. But when I'm sitting on the front porch in a rocking chair, I'm rolling a duby to go with my rum and coke regardless.
