Lumex - 2026 Pricing, Features, Reviews & Alternatives

Lumex is a browser-based SaaS workspace built for IEC 62305-2:2024 lightning risk assessment. The platform runs the full third-edition risk method entirely in the browser, computing collection areas, dangerous-event rates, damage probabilities, and loss factors from the standard's coefficients. Results are rolled into nine risk components, each evaluated against its tolerable threshold, with a full coefficient trace linking every figure back to the specific clause, equation, or table in the standard. No installation is required; all computation and report generation execute client-side. The platform targets electrical consultants, MEP and design firms, and LPS installers and auditors, with primary coverage in India and the GCC (UAE), and additional coverage in Singapore and the United Kingdom.

The feature set spans the full assessment workflow. Projects are structured by site and zone, each with independent revision lines. Role-based access control supports Admin, Project Manager, and Sales Manager roles, enabling team collaboration without per-engineer file management. An append-only audit log records every edit, approval, and impersonation session, providing a defensible compliance trail for clients and auditors. Branded PDF reports of 10 to 14 pages include an executive summary, methodology, per-zone results, engineer attestation block, and configurable logo and accent colour. What-if scenario modeling covers LPS class selection and SPD coordination. Periodic LPS inspection checklists per IEC 62305-3 are included. Multi-tenant data isolation with encryption and compliance with GDPR, UK GDPR, and India's DPDP Act are enforced per jurisdiction. GST-ready invoicing supports CGST, SGST, and IGST splits, GSTIN on invoice, FY-sequenced numbering, and multi-currency billing. Secure shareable report links and a 14-day free trial on all plans are available.

Lumex explicitly excludes AI from all risk calculations. The risk engine (Voltrace) is fully deterministic: the same inputs always produce the same outputs, and no AI component can write, edit, or override any result. Planned assistive AI features, clearly scoped outside the engine, include automated risk analysis highlighting drivers per risk component, AI-drafted narrative sections subject to engineer review and approval before issuance, AI-suggested protection options ranked by effect with engineer final authority, and predictive flagging of likely-failing risks during data entry. The platform is independent of any lightning protection hardware manufacturer, removing potential conflicts of interest from protection recommendations.
