What does electricity cost where you are? I madea few worst case assumptions here.

Six day workweek with a few days off for holidays is about 300 days a year?

490 watts x 12 hours x 300 days = 1,764 KWH per year

166 watts x 12 hours x 300 days = 598 KWH per year

So, If electricity is $1 per KWH, then you could save the thousand+ dollars. If electricity is $0.10 per KWH, then you will save $115 per year. I have no idea what the cost of power might be for you, but I would not consider this unless the payoff was less than five years, as the life of the bulbs may be less than that. You will be helping the environment and society by not using as much power, but the direct economic costs to you should win out.

Check out the electricity costs and the assumptions for the power (time and days), and you can adjust these numbers accordingly.

Subject: [Chevelle-list] off topic garage lighting

hi wondering if there are any electricians out there who know if this is true, a salesman told my friend he could switch his fluorescent lights from a T12 to a T8 type of light and he could save $1179.00 a year on his light bill and have more light with the same ammt of fixtures (13). I priced the fixtures out and they are 24.00 more per light (twin 8' tube) or 6.00 more per light for a 4-tube- 4' bulb light. I need about 90 of them for my shop so the cost on the light fixtures would be a lot more, but if this savings on lighting bills is true maybe it would be worth it??

(my friend owns a small muffler shop so the lights are on at least 8 hours a day). they claim the wattage on his fixtures are 490, and the new fixtures are 166.

thanks for the help.
