Context
LEDEX sells lighting for hazardous and demanding industrial environments. Customers often need a rough lighting layout before they can choose a fixture or request a sealed photometric study. That first step used to require an engineer to prepare every comparison.
I led the software work for a self-serve estimator inside the LEDEX product platform. It gives customers and sales teams a visual starting point while keeping a clear boundary between an estimate and an engineering document used for permits or tenders.
My responsibility
I translated the lighting workflow into product requirements, data contracts, calculation rules, and a customer-facing interface. I also connected the tool to the product catalog and quote process, so users can move from a room layout to a real fixture configuration without re-entering the same information.
Engineering work
Photometric data pipeline
The estimator loads catalog IES files, parses their photometric distributions, and maps each record to a valid fixture configuration. Validation catches missing or incompatible data before a calculation reaches the interface.
Calculation engine
The browser evaluates room dimensions, work-plane height, reflectance, fixture spacing, mounting height, and target illuminance. A Web Worker keeps recalculation off the main thread. Users can compare layouts without freezing the controls or 3D view.
Layout and handoff
The interface combines a 2D plan, 3D scene, heatmap, isolines, summary results, and fixture controls. Users can save a project, print a layout, or send the selected configuration to LEDEX for pricing and engineering review.
Result
The production tool gives customers an immediate way to test a layout idea and compare real LEDEX fixtures. It also gives the technical team structured project inputs when a customer requests a quote or sealed study.
The estimator states its limits in the interface. Electrical-code submissions and permit work still go through qualified engineering review.
