How to tell if a light fixture has T12 vs. T8 lamps?

Spin the flicker checkerChoppy, checkered pattern= magnetic ballast = T12

lampConcentric, gray rings = electronic ballast = T8 lamp


T12 vs T8 ActivityActivity Instructions:

Break up into teams of 3-4, grab a flicker checker, and select a specific site to conduct a linear fluorescent light audit, specifically looking at existing T12/T8 lamps in the building.

Use the worksheet provided to collect information on the study site’s existing lighting condition.

Calculate the potential electricity, cost, and GHG savings associated with upgrading the existing lighting conditions, if an upgrade is needed.


Energy Audit #3 - Delamping:

What is it, and why is it important?


Recommended Lighting Levels

How to Use a Light Meter

How To Use It

Make sure the sensor is covered.

Check that the “Range” switch is selected to A

Turn on the “Power” button.Remove the sensor cover.Read the lighting level.

Readings should be taken at the level where the work occurs.

Make sure user does not cover the sensor


Layout of room:

Sample light levels collected from room:

3 linear fluorescent fixtures

Light Meter ActivityConduct a light analysis of the room/building you are in. Example:


Light Meter ActivityActivity Instructions:

Break up into teams of 3-4, grab a light meter, select a specific site to conduct a light meter analysis in the building.

Draw a floor plan of the study site as shown in the previous slide, and write down different light meter levels (foot-candles). Collect at least 6 light meter levels in different parts of the room.

Based on the recommended lighting level, assess if there is too much/too little light in the study site, and what next steps you would recommend to the facilities staff to help them save energy.


What’s a plug load? Plug loads make up about 4% of all electricity

use in the US What’s a run watt?

Power drawn by a plug load while in operation What’s a phantom load?

Aka energy vampires, standby loads U.S. consumption of phantom loads = electricity use of

Greece, Peru, and Vietnam, combined.

Energy Audit #3: Plug Loads and Phantom Loads

Phantom load on this printer is 2.8 watts.

This translates into _______kWh a year.


Typical Appliance Energy Use


Plug Load ActivityActivity Instructions:

Break up into teams of 3-4 and pick at least one plug load and one watt meter.

Using the handout, calculate the run watts and the phantom load (if any), along with the associated annual energy use, cost, and GHG emissions.
