Generally, there are higher losses in older control gear (more total watts) and less light from old burners. (things don't grow as well or happen as fast.) Cheers . . |
Yes I just did the bulb sizes to keep it simpe for everyone. But the math is solid. All you would need to do is add 5% to
Your Lights total for a little leway. You could also use the
Your Setup cells to get totals for your pumps, fans, or anything else that has a steady draw and is on a timed schedual. Add them to Your Lights totals and get a Compleat cost instaid of just lights.
Anyways thanks for your input and I hope it was informitive.
