The units have four lamps each with a ballast for each pair of lamps. The ballast read ". 80

**amps**" which**would**be 1.6**amps**per unit. So 15 divided by 1.6 is 9.375.

Keeping this in view, how many watts does a t12 fixture use?

Fluorescent **T12** The lumens per **watt** of **T12** is roughly around 60 and a CRI of 70. Your average 2 lamp **fixture** will consume 90 **watts**, the 4 lamp version will consume roughly 160 - 170 **watts** depending on the ballast.

**T12**four-lamp fixture

**uses**172 watts of

**power**between the lamps and

**ballast**. LED equivalents typically

**use**only 50 watts, 71% less energy per fixture. [3] Not only are they brighter per watt, they also last longer than even the preferred florescent bulbs.

Also to know is, how many amps does a fluorescent light use?

The Standard **T12 lamp produces** 2,650 initial **lumens** per **lamp**. The standard T8 **produces** 2,800 initial **lumens** per **lamp**, 6% brighter. But the standard **T12 lamp produces** 2,300 design **lumens** and the T8 **produces** 2,660 design **lumens**.
