ArmadilloLED are committed to provide educational information so you can cut through competitive manufacturer claims and separate fact from fiction. We want to help you find products that meet your expectations. We’d be happy to discuss your Lighting requirements and offer guidance for you to make fair comparisons on LED.

1. Performance Delivery at Application Level
2. Ask for certified Photometric Data
3. Establish Lumen depreciation
4. Look at Light loss Factors
5. Evaluate Lifetime Luminaire ROI
Total Solution Approach
As you begin investigating LED lighting for your specific applications, keep in mind that you're buying an integrated system, not just individual components. An effective LED lighting fixture is only as strong as its weakest link. Look for features that provide the key benefits you expect on every installation – performance, longevity, efficiency, style and reliability.
Not all LED luminaires are created equal
ArmadilloLED understand and add value for providing educational information so you can cut through competitive manufacturer claims and separate fact from fiction. Armadillo use tools for light modelling that all can understand by using freely available Dialux software tools to guide you in making informed buying decisions. Plus, our application engineers and product representatives are well-trained and will help you objectively consider your options.

Use Measurable Performance Data
Spec Sheets and IES Photometric files
Case study installations
Product Data Sheets
ISO Certification

1. Performance Delivery at Application Level
Do not be lead by data only . Many claimed manufacturers supply data from other lighting components and one time lab results. Conduct "in field" application level performance evaluations using IESNA recommended practices and standards. Utilise available design software and application engineering practices to predict application level performance. Evaluate relevant and credible case studies. (case studies link)
2. Ask for Certified Photometric Data
Make sure the LED luminaire manufacturer provides a certified photometric report (per IESNA LM-79) from an approved DOE lab to validate the manufacturer's photometric performance claims.
3. Establish Lumen Depreciation
Obtain lumen depreciation (life) data for the LED luminaire supported by the LED chip manufacturer's IESNA LM-80 test data, directly correlated to luminaire level performance. Along with thermal characteristics to maintain light levels.
4. Look at Light Loss Factors
When a light fixture is activated, it produces light which must leave the lamp, then the fixture, then reach the work plane where it is needed. Along the way, a number of operating and environmental conditions interfere with the transmission of light, resulted in wasted lumens.
Please bear in mind the light loss figure supplied is only as good as the manufacturers data, thermal properties and design of the fitting itself. Using the manufacturer's LED luminaire lumen depreciation data, you can only apply if supported by the correct thermal design for an accurate light loss factor..
As an example, a typical outdoor dusk-to-dawn application may be evaluated at a 50,000 hour (~11 – 12 year) application life. Based on this example, you would conduct an evaluation based on each manufacturer's 50,000 hour lumen depreciation values. See Benefits of LED (link)
5. Evaluate Lifetime Luminaire ROI
Analyse initial investment versus lifetime value by considering all LED fixture benefits such as lighting performance, total power consumption, maintenance and warranty. The entire luminaire must be built to last for the length of the application life.
