430W HPS Electricty Cost Question!

[Italiano715]

sounds about right...:thumbsup:

I checked mine: 462 kw hours divided by $47.19 = $0.10 kw

I think you're right in the ballpark! When I added my 400, the bill bumped about $25/mo.

You are being very generous with the amount allowed for the ballast, my 400 HPS only pulls a total of 410 watts. It would need to be among the worlds worst ballasts to consume an extra 50!

I appreciate the feedback my friends....I was just paranoid on to HOW much extra it would cost a month. Was expecting a lot more before I did the math. I need to keep that conversion chart for later references!

must spread some reputation around before giving it to Dutch and EvilC again!

Problem comes with electricity costs. So I found a conversion table for the cost and did the numbers. Now I sha'll put them down here and can somebody please confirm or correct me if I'm right/wrong. Alright....Well I checked the recent light bill and I used 742kw hours this month and the bill was $102. So, I divided the 102 into the 742 and it came out to .137 rounded to .14. Rating: 5
