How does “Fringe Flux” affect my calculation?
Fringe Flux is the energy created by a lighthead beyond the standard 57 data points defined by the standard that could possibly affect the compliance of a vehicle. All lightheads produce light outside of the 5° Up/45° Left to 5° Down/45° Right however some produce large amounts of energy beyond that range, such as a 600 Series Rota-Beam™ or V-Series™ lighthead. Recognizing Fringe Flux helps keep Non-Permissible light out of zones that it should not be in and could also contribute to other zones that would receive the energy.
Example 1 – What Fringe Flux Looks Like. A lighthead can typically produce up to 180° of light, which will contribute 90° of energy to Zone A, and 45° of energy to zones B and D.
Example 2 – Rotating Non-Permissible Light into a Zone. With the ability to rotate lightheads and lightbars when mounting them on the vehicle the need to look at Fringe Flux becomes necessary. In this example, the lightbars are rotated 45°. If a White flashing alley/warning light is included in the configuration it will be contributing to Zone C. If the Standard doesn’t allow White light in Zone C, then AOG will calculate how much energy is being added and determine if it’s acceptable to have this light on. If AOG determines too much energy is being added to Zone C, it will turn off the offending lighthead(s) for all Modes of Operation. *Non-Permissible light never contributes to Zone Totals.
Example 3 – Permissible Light into a Zone. Two 600 Series Rota-Beam™ lightheads are mounted in Zones B and D. Because of the design of the 600 Series Rota-Beam, it produces a large amount of Fringe Flux into adjacent zones (zones A and C). If the Standard allows these colors, AOG will include any Fringe Flux in the appropriate Zone Totals. If the colors are producing Non-Permissible light in the adjacent Zones, refer to example 2.
I used a .brx file that I made last week and AOG is asking me if I want to “Use Historic Data” or “Don’t Use Historic Data”. Which option should I choose?
The option for using Historic Data will appear if the .bxr contains a lighthead that is linked to old data which has since been superseded. You can continue to perform the calculation by selecting “Use Historic Data” to use the Historical Data. However, Whelen recommends that you always create a new .bxr to access the most up-to-date data.
Standard: NFPA 1906. I’ve put a White/Red lighthead in Zone A. Why does it give me a warning saying, “Non-permissible light color in Blocking mode of operation”?
The warning message indicates that the Zone Totals will not include the white light in Zone A during Blocking mode of operation.
Standard: SAE J2498. I’ve put an Amber/Red lighthead in Zone A. Why does it give the warning: “Non-Permissible light color in calling mode of operation”?
The warning message indicates that the Zone Totals will not include the amber light in Zone A during Calling mode of operation.
What are “Candela-Seconds/Minutes (CdSM)”?
Candela-Seconds Per Minute is the amount of flash energy over time, independent of color. For example, Red CdSM can be combined with Blue CdSM to calculate total flash energy over time for the product.
Candela-Seconds/Minutes = Candela-Seconds x 60 ÷ Flash Period
What do you mean by “Permissible Light”?
Permissible Light is any light in a zone that is allowed to be operating during a Mode of Operation.
What do you mean by “Non-Permissible Light”?
Non-Permissible Light is any light in a zone that is NOT allowed to be operating during a Mode of Operation.
What is “Candela (Cd)”?
Candela-seconds are a unit of flash energy. Candela-Seconds = Candela x Flash Duration.
What is the “!” symbol next to my uploaded Lightbar?
If the uploaded .bxr file contains a lighthead that is not available to the AOG, a “!” will be displayed to indicate missing data. Hovering over the lightbar will display which lightheads are missing. Please contact email@example.com for help. We will review the request to ensure that the data is made available.
What is the difference between System Type = Standalone Lights vs Lighting Control System?
Standalone Lights will treat each lighthead as if they are not connected to a control system, and only the low-power values hardcoded into the lighthead can be used. If the lighthead doesn’t have a low-power wire, it will not have an option for low-power. Lighting Control System allows the user to control the power percentage in 5% increments. This will allow the ability to apply low-power to all lightheads when controlled by a control system.

How do I determine the model of my lightbar?
Determining the model lightbar you have is the most important thing you can do before contacting us for technical support.

What is the difference between SAE Class 1, 2 and 3?
These are SAE intensity categories.
- Class 3 products are typically used inside buildings where there is no ambient sunlight. For Amber warning products, Class 3 products provide approximately 40% of the minimum intensity of Class 2 products.
- Class 2 products are typically used by utility vehicles and other equipment found working along the roadside. The minimum intensity for Class 2 products is approximately 2.5 times that of Class 3 products.
- Class 1 products are intended for primary emergency vehicles such as police, fire, and ambulance vehicles. Many states are beginning to mandate the use of Class 1 amber warning products where previously Class 2 was the minimum requirement. Check with local authorities to determine what is needed in your area. Class 1 products are approximately four times the minimum intensity of Class 2 products.
