What Is Lumex

Lumex is Webority's lightning risk assessment software. It turns the full IEC 62305-2:2024 (3rd edition) method, not a simplified estimator, into an automated, auditable engine, Voltrace™, so your team models a structure once and gets the risk components, the overall risk and the frequency of damage against the tolerable limits, and the resulting protection decisions from a single source of truth.

Automated lightning risk calculation with Voltrace
Compute — Automated Risk Calculation

Voltrace™, our risk engine, computes your lightning risk against the tolerable limit, plus the frequency of damage to internal systems, in real time, with no spreadsheet formulas to maintain.

Traceable lightning risk calculations
Prove — Calculations

Every result carries a full coefficient from the IEC 62305-2 standard, so you can defend each figure line by line for clients or auditors.

Branded lightning protection reports
Deliver — Branded Protection Reports

Generate a branded, client-ready lightning protection report in minutes, with your logo and colours built in.

Append-only audit and compliance log
Trust — Audit-Ready Compliance Log

Every action is saved to an append-only audit log, so you keep a defensible lightning risk compliance trail on every assessment.

Lightning risk engineers reviewing standard-compliant assessment data instead of fragile spreadsheets

One Stray Formula Away From a Wrong Number

A DIY Excel model and a rebranded Word template break right when it matters most, and nobody recalls who changed what. Lumex runs the whole assessment in one place, so a day of that manual work is instead delivered as a signed, standard-compliant report in a single sitting.

Because Lumex is a custom-built lightning risk platform rather than a generic calculator, the risk math stays deterministic while the workflow is shaped around how firms actually deliver assessments. It runs on a cloud-native architecture, so multi-site projects and multiple engineers work from one source of truth as your volumes grow.

IEC 62305-2:2024 (3rd edition)

Lumex implements the current third edition of the standard, IEC 62305-2:2024, which cancels and replaces the 2010 second edition, so your assessments reflect the methodology in force today.

IEC 62305-2 risk management
IEC 62305-2

The risk management methodology of the 2024 third edition that Lumex automates from collection area through the risk components to the overall risk and frequency of damage.

Risk and frequency-of-damage model with ground strike-point density
Risk, Frequency & NSG

The 2024 edition replaces ground-flash density (Ng) with ground strike-point density (Nsg) — the input that drives the number of dangerous events and the calculated risk. Lumex sources Nsg directly or derives it from Ng.

Single risk combining loss of life and loss due to fire
Single Risk Model

The 2024 edition introduces a single risk that combines loss of human life and loss due to fire, so protection decisions rest on one consolidated figure against the tolerable limit.

How Lumex Runs the IEC 62305 Risk Workflow

Six guided steps take an assessment from a blank structure to a signed, standard-compliant report, with the calculation shown at every stage.

General info: building and location Site and structure details Supply lines entering the structure Building floor plan divided into colour-coded protection zones Run the analysis and compute the risk Review the result and issue the report
01

Enter the General Information

Name the building, choose a building-type preset, and set its location, which fills in local thunderstorm days and ground strike-point density (NSG). Add the tolerable frequency and location factor, the structure type and geometry (length, width, height), and attach structure photos.

02

Define the Site and Structure

Set the density factor k and review the computed ground-flash and ground strike-point density (NG / NSG), then the construction material, structural shielding, environmental factor, LPS class, and any thunderstorm-warning system.

03

Add the Supply Lines

Describe the power and telecom services entering the structure, HV/LV power and shielded-pair or optical-fibre telecom, with their lengths, installation and environmental factors, shielding, bonding, withstand voltage, and SPD protection.

04

Define the Zones

Split the structure into zones and set each one's floor type, protection against shock, position of persons, fire risk and protection, internal shielding and wiring, coordinated SPDs, and the loss types that apply.

05

Run the Analysis

Lumex computes the collection area and the dangerous-event rate, then the per-zone probabilities and risk components, and finally the overall risk and frequency of damage against the tolerable limits. Adjust protection measures such as LPS class and watch them recalculate in real time.

06

Review the Result and Issue the Report

See the final verdict, then generate the branded, audit-ready report, preview, download, or share it, with an optional AI-drafted narrative and a protection optimizer that compares what-if scenarios such as LPS class and SPD coordination.

Core Modules Inside Lumex

Every module works from the same assessment data, so the risk engine, the reports, and the audit trail stay in step with each other.

Voltrace™ Deterministic Risk Engine

Voltrace™ is a real calculation engine, not a lookup table, that computes the risk components, the overall risk, and the frequency of damage against IEC 62305-2:2024. The same inputs always produce the same outputs, and the risk math is kept free of AI so results stay defensible.

Lumex deterministic risk engine module

Branded Report Generation

A branded, audit-ready assessment report, typically 10 to 14 pages, generated directly from the assessment and shareable as a PDF or a secure owner link, so the report always reflects the underlying calculation and the engineer's sign-off.

Lumex branded report generation module

Audit & Compliance Log

An append-only log records edits, approvals, and sign-offs across an assessment, giving you a defensible trail of who changed what and when, without the version drift of spreadsheet-based workflows.

Access & Multi-Site Workspace

Role-based access, with a multi-project, multi-site workspace that keeps each site's assessment and revision history organised under one project.

Lumex access and multi-site workspace module

Multi-Tenant Data Isolation

Each firm's projects and reports are isolated under a multi-tenant model, so your assessment data stays separated from every other organisation using the platform.

Each tenant's data held in its own isolated, locked vault

AI Assistant (Optional)

An optional AI assistant drafts the report narrative and executive summary and ranks mitigation options such as LPS class and SPD coordination. The risk calculation stays deterministic and AI-free, so the assistant never writes, edits, or overrides a computed risk value.

What Lumex Changes for Each Role

Lightning risk assessment software is a delivery and accountability tool, not just a calculator. It changes how four groups work, and supports the wider digital transformation of how assessments get done.

01
For Electrical Consultants

Faster assessments with traceable numbers, so the report carries a clear line from each result back to the standard and to your professional sign-off.

02
For MEP & Design Firms

One workspace for many projects and sites, so protection decisions stay consistent across a portfolio instead of living in scattered spreadsheets.

03
For LPS Installers

What-if scenarios for LPS class and SPD coordination make it easier to justify the protection measures you install against the assessed risk.

04
For Auditors & Inspectors

An append-only audit log and periodic inspection reports give reviewers a defensible record of how each assessment was reached and signed off.

For the People Who Put Their Name On It

Different firms are accountable for lightning risk in different ways. Lumex fits the way each of them delivers and signs off an assessment.

Lumex lightning risk assessment software users

Frequently Asked Questions

Lumex is lightning risk assessment software that automates the IEC 62305 methodology. It lets electrical consultants, MEP firms, and lightning protection specialists model a structure, compute the overall risk and the frequency of damage against the standard's tolerable limits, trace every coefficient back to the standard, and generate audit-ready reports, replacing fragile spreadsheet-and-document workflows with a single, deterministic platform.

Lumex is built to IEC 62305-2:2024 (risk management), the third edition of the standard, which cancels and replaces the 2010 second edition, and reflects the 2024 move from flash density to ground strike-point density (NSG).

Traditional lightning risk assessment relies on spreadsheets and document templates where formulas can break, versions drift, and there is no reliable audit trail. Lumex computes the risk components (RAT, RAD, RB, RC, RM, RU, RV, RW, RZ) and the resulting risk and frequency of damage with a deterministic engine, Voltrace™, so the same inputs always produce the same outputs. Every value can be traced to the relevant coefficient, and reports are generated directly from the assessment.

Lumex is designed for electrical consultants, MEP and design firms, and lightning protection system (LPS) installers and auditors, the professionals who are accountable for lightning risk assessments and the reports that carry their sign-off. Each role works within a shared, multi-project workspace scoped to their responsibilities.

Lumex applies role-based access control, keeps each firm's data isolated under a multi-tenant model, and maintains an append-only audit log of edits and approvals. It aligns with India's DPDP Act, supports SAML 2.0 single sign-on, and targets a 99.9% uptime service-level agreement.

No. Every risk value is computed straight from the IEC 62305:2024 coefficients, and the calculation is deterministic, so the same inputs always produce the same outputs. An optional AI assistant can help draft the report narrative and rank mitigation options, but it never writes, edits, or overrides a risk value.

Lumex generates a branded, audit-ready assessment report, typically 10 to 14 pages, covering the structure model, the risk and frequency-of-damage computation, and protection recommendations with an engineer sign-off. It also produces a 2 to 3 page periodic inspection report to IEC 62305-3, and every result carries a coefficient trace, so the document is defensible. Reports can be shared as a PDF or a secure owner link.
