Photometric files, datasheets, BIM objects, and technical guides — all in one place. Free to download for lighting designers, architects, and MEP consultants.
Need a custom product specification? Contact our technical team.
Accurate photometric data tested in our in-house integrating sphere. Download IES files for all standard products — DIALux project files available on request.
Comprehensive datasheets with dimensions, electrical specifications, optical data, thermal performance, materials, and certifications. Download as PDF.
Practical guides written by our optical and electrical engineering team. Designed to help you specify better lighting — regardless of which brand you choose.
What CRI really means, how it's measured, and why it matters for your project. Plus: when CRI 80 is enough and when you need 95.
A complete comparison guide covering architecture, dimming performance, cost, scalability, and use cases for each protocol.
A designer's practical guide to IES files, candela distributions, beam angles, and what the numbers actually mean on site.
How we engineer fixtures for extreme temperatures — and why cheap LED fixtures fail in Gulf-region summers.
Our technical team works directly with designers and engineers to make specification seamless. Three ways we support your project.
We provide complete specification text for your projects — ready to insert directly into tender documents. Includes performance criteria, material standards, testing requirements, and warranty terms.
Request spec text →Send us your floor plan or project brief, and our lighting designers will provide full DIALux calculations, false-colour layouts, luminaire schedules, and energy consumption reports.
Request calculations →Need to see and test a product before specifying? We provide evaluation samples for qualified projects — typically shipped within 10 working days, returnable after project completion.
Request samples →Integrate Yakeen products directly into your project models. All BIM objects include accurate dimensions, photometric data, and material definitions.
All certification documents available on request. We provide complete certification packages for every order to ensure smooth customs clearance worldwide.
Our engineering team is here to help with photometric questions, specification writing, DIALux calculations, or custom product engineering. Response within 24 hours.
Contact Technical Team →All our standard product IES files are tested in our in-house integrating sphere laboratory following LM-79 standards. Custom product photometrics are also tested — not simulated — for maximum accuracy.
Send your floor plan, project brief, and lighting level requirements to [email protected]. We'll provide full DIALux calculations, false-colour renderings, luminaire schedules, and energy reports within 5-7 working days for standard projects.
Yes. Our technical team provides complete specification text including performance criteria, material standards, testing requirements, warranty terms, and compliance statements — ready to insert directly into your tender documents.
Our standard Revit families include type catalogs with all standard product variants (sizes, power, beam angles). For custom projects, we create fully parametric families matched to your exact specifications.
All CAD blocks are provided in DWG format (AutoCAD 2018+ compatible) and include plan, elevation, and section views with accurate dimensions. Other formats (DXF, PDF) available on request.
Standard certification documents (CE, CB, RoHS, ISO 9001) are typically sent within 24 hours of your request. Market-specific certifications (SASO, ESMA, G-Mark, EAC) may take 2-5 working days depending on the scope required.
Yes. LM-80 test reports from our LED suppliers and our own TM-21 lifetime projections are available for all product lines. We guarantee L70 of 50,000+ hours at rated operating temperature.
Absolutely. We provide evaluation samples for qualified projects. Samples are typically shipped within 10 working days and are returnable after project completion. Contact us to request samples for your project.
