Frequently Asked Questions

What are IES files?

IES files contain photometric data. The majority of Venture Lighting fixtures have IES files which can be downloaded by clicking the icon adjacent to the product description tables on our website.

How can I view an IES file?

IES files contain luminous intensity data and angular information which is typically presented as polar diagrams and cone diagrams. Neither of these diagrams is included in the file format itself, but can be generated from the files by using lighting analysis and design programs such as Photometrics Pro, Photometric Toolbox, Relux or Dialux. A free viewer can also be downloaded from

How is LED product life defined?

LED product life is defined differently from traditional light sources and is the maintained lumens of the product (lumen maintenance), if there are no product failures. Rated life is usually limited to 6 times the actual measured lumen maintenance. Projected or Calculated Life is calculated to project the number of hours when the LEDs will reach 70% of their initial lumens (L70).

What are the certifications for LED Products?

UL (Underwriters Laboratory) & ETL (Intertek) - Organizations which will certify the safety of a product if the product passes series of rigorous testing protocols. LED lamps with internal drivers can be tested against these protocols. Not all LED lamps are UL or ETL Listed. Venture has taken the added steps to gain this approval.

Energy Star & Design Lights Consortium (DLC) – Organizations which will certify the performance of a product. Products are approved by the appropriate organization which reviews the lamp efficiency, CCT, CRI, electrical characteristics, and life data to confirm the product meets the acceptability criteria established for a product category. Not all LED products are Energy Star Certified or DLC Certified.

When the surge protection device in my fixture reaches end of life will the light shut off?

The surge protection devices utilized in Venture's lighting systems are designed to be transparent at end of life, keeping the lights ON for safety and security.
