What is the hansonled led module IES file?

An IES file is a standardized plain-text document that stores the measured photometric data of a luminaire or light source. The format is defined by ANSI/IES LM-63, and the data is usually generated through IES LM-79 testing in a certified photometric laboratory. In simple terms, the file describes how light leaves a fixture at every angle, allowing lighting software to predict real-world performance.

For a LED module manufacturer like HansonLed, an IES file is the digital fingerprint of a specific module. It tells designers how bright the module is, how the light is distributed, and how suitable it is for a particular sign application.

Although the file looks like a block of numbers and labels when opened in a text editor, each section has a clear purpose. A typical HansonLed LED module IES file includes the following information:

• Fixture identification: Manufacturer name, product series, and model description.
• Luminous flux: Total lumen output of the tested module.
• Luminous intensity distribution: Candela values measured across horizontal and vertical angles.
• Photometric type: Indicates whether the distribution is direct, indirect, or general diffuse.
• Electrical data: Wattage, voltage, and related parameters used during the test.
• Test conditions: Information about the testing lab, equipment, and measurement setup.

Because HansonLed produces a wide range of modules including channel letter LED modules, light box modules, and high-efficiency backlight modules, each product series may have its own IES file that reflects its unique optical characteristics.

Signage lighting must meet several goals at once: visibility, uniformity, energy efficiency, and compliance with local codes. Guessing how a module will perform can lead to hotspots, uneven illumination, or unnecessary power consumption. An IES file removes that uncertainty.

Designers import the file into programs such as DIALux, AGi32, or Relux to simulate the final result. The software calculates illuminance levels, uniformity ratios, and beam spread based on the actual measured data in the file. This is especially important for applications such as:

• Channel letters where even brightness across the face is critical.
• Light boxes that need consistent backlighting without dark corners.
• Sign cabinets that require precise spacing and power planning.
• Retail and commercial signs that must meet brand appearance standards.

Using an IES file is straightforward. Download the file that corresponds to the HansonLed module model you are considering, then import it into your lighting design software. From there, you can position the modules inside your digital model, adjust spacing and orientation, and generate photometric reports that show expected performance.

If you are unsure which IES file matches your chosen product, contact HansonLed directly. With over ten years of experience in LED signage lighting, the team can guide you to the correct file and help interpret the results for your specific application.

The HansonLed LED module IES file is more than a technical document. It is a practical tool that helps lighting professionals design better signage with confidence. By converting measured photometric data into predictable performance, IES files support smarter product selection, accurate spacing, and energy-efficient installations. Whether you are working on channel letters, light boxes, or large commercial signs, requesting the correct IES file is a simple step that can significantly improve your project outcome.
