Re: [Chevelle-list] off topic garage lighting
There you go, an even better answer than I made, because you have real numbers and light output (which I forgot). Brad From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dean VandergriffSent: Friday, November 03, 2006 11:18 AMTo: The Chevelle Mailing ListSubject: Re: [Chevelle-list] off topic garage lighting Harlan, I do lighting design work for a fluorescent fixture manufacturer. There is more than one type of both T12 & T8 lamps. If your friend is using an F96T12HO lamp, two of them have a system wattage of 216 watts & around 9000 lumens per lamp. F96T12 slimline is actually a 75 watt lamp with a system wattage of 158 & around 6300 lumens per lamp. These are both 8’, T12 lamps & my wattage figures are based on magnetic ballasts (most likely for older fixtures). Incidentally, both of these lamp types are rated for 12000 hours per lamp. T8 slimline lamps are a 59 watt lamp & have a system wattage for two lamps of 110 watts, are rated at 5950 lumens per lamp, & a 20,000 hour life. The 86 watt T8 HO has a system wattage of 160 watts, 8200 lumens per lamp, & 18,000 hour life. The 4’, 32 watt T8 lamp is rated for 20,000 hour life & you can operate 4 of them on a single ballast at 114 watts & 2950 lumens each. All of my figures for the T8 lamps are based on solid state, electronic ballasts. Four of these is a good replacement for two of the 8ft, T8 slimline lamps. You can get the same light output at about the same energy cost & you’re buying a less expensive lamp that’s easier to store & dispose of since it’s only a 4’ lamp. Bottom line, be sure of what you’re comparing. You could replace T12HO with T8 slimline fixtures & save about 50% on electricity, but then you’d only end up with about 2/3 of the light that you started with.

Re: [Chevelle-list] off topic garage lighting
Harlan, I do lighting design work for a fluorescent fixture manufacturer. There is more than one type of both T12 & T8 lamps. If your friend is using an F96T12HO lamp, two of them have a system wattage of 216 watts & around 9000 lumens per lamp. F96T12 slimline is actually a 75 watt lamp with a system wattage of 158 & around 6300 lumens per lamp. These are both 8’, T12 lamps & my wattage figures are based on magnetic ballasts (most likely for older fixtures). Incidentally, both of these lamp types are rated for 12000 hours per lamp. T8 slimline lamps are a 59 watt lamp & have a system wattage for two lamps of 110 watts, are rated at 5950 lumens per lamp, & a 20,000 hour life. The 86 watt T8 HO has a system wattage of 160 watts, 8200 lumens per lamp, & 18,000 hour life. The 4’, 32 watt T8 lamp is rated for 20,000 hour life & you can operate 4 of them on a single ballast at 114 watts & 2950 lumens each. All of my figures for the T8 lamps are based on solid state, electronic ballasts. Four of these is a good replacement for two of the 8ft, T8 slimline lamps. You can get the same light output at about the same energy cost & you’re buying a less expensive lamp that’s easier to store & dispose of since it’s only a 4’ lamp. Bottom line, be sure of what you’re comparing. You could replace T12HO with T8 slimline fixtures & save about 50% on electricity, but then you’d only end up with about 2/3 of the light that you started with.

Re: [Chevelle-list] off topic garage lighting
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.

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.
