Your IEC 62305 questions, answered

Lumex is web software for IEC 62305:2024 lightning risk assessment. You model a structure and the engine computes your lightning risk against the tolerable limit, plus the frequency of damage to internal systems, from the standard's coefficients. What you walk away with is a branded, audit-ready PDF you can hand straight to the client, built by Webority Technologies.

The deliverable is a 10 to 14 page PDF: the structure model, the full risk computation, protection recommendations, an engineer sign-off block and a revision history. It is the document a building owner files for compliance. Lumex also produces a short periodic LPS inspection checklist for the routine maintenance cycle.

It is the full IEC 62305:2024 method, not a simplified estimator. Lumex computes every risk component and resolves your lightning risk against the tolerable limit, plus the frequency of damage to internal systems, all from the standard's coefficients. Every number on the report traces back to the clause behind it, and the how it works page walks through the method.

Yes. Alongside the 62305-2 risk assessment, Lumex produces a periodic LPS check per IEC 62305-3: a 2 to 3 page checklist for the routine (typically annual) maintenance cycle, covering physical LPS condition, the earth-resistance reading, a defect list and photo attachments.

Yes, on the Enterprise plan. Your reports carry your firm's name and logo, your accent colour and your sign-off line, so the deliverable looks like your firm's, not ours. Reports are watermarked during the 14-day trial and stop being watermarked as soon as you subscribe. See the pricing page for what each plan includes.

No. Every number comes from the deterministic IEC 62305-2 engine, and the compliance verdict is the engine's alone. Lumi, the Lumex assistant, writes the prose around those figures, the executive summary, the methodology note and the recommendations, and answers questions about the assessment. It never produces a risk value or decides a pass or fail.

The full report is the filing document: executive summary, the standard reference, sources of damage, every risk and frequency component, environmental data, the structure and its collection areas, the assessment before and after protection measures, the conclusion and the legal obligations. The short report keeps the same figures and the same verdict but drops the explanatory pages, so it suits a quick internal review or a client update.

Yes. Each project carries its revisions with a revision number, the date and a note on what changed, so a reviewer can see how the assessment reached its current state and which version a client was issued.

Lumex is open. You can start a 14-day free trial today, no sales call needed. See the pricing page for the plans.

Sign up and your workspace is ready in a couple of minutes. Every plan starts with a 14-day free trial: 2 seats, 3 projects, 5 assessments and 20 AI messages, with watermarked reports. A card is required to open the trial, and nothing is charged until it ends.

Professional is $49 per seat per month, or $490 per seat per year with two months free. Enterprise is $79 per seat per month, or $790 per seat per year, from a minimum of 10 seats. Both are billed in USD and include unlimited projects, assessments and report downloads. The full breakdown is on the pricing page.

You pay per seat, never per report. Every plan runs unlimited projects and assessments, and you can download as many full and short PDF reports as you need at no extra cost, so a busy month and a quiet month cost the same. Add or remove seats as your team changes. The full breakdown is on the pricing page.

Every plan starts with a 14-day free trial that covers 2 seats, 3 projects, 5 assessments and 20 AI messages, with reports watermarked until you subscribe. There is no permanently free tier. Once you subscribe, projects, assessments and report downloads are unlimited, and you add a seat for everyone who needs a login.

A seat is one person with their own login in your workspace. Roles cover how they work, from admin and engineer to reviewer, field surveyor and viewer, and every one of them uses a seat. Professional starts at one seat with no minimum. Enterprise starts at ten.

Yes. An upgrade takes effect as soon as it is paid for, and your previous plan retires the moment the new one is live. A downgrade is scheduled for your next renewal, so you keep everything you have paid for until the period ends, then the smaller plan starts.

You keep full access until the end of the period you have already paid for. After that the workspace stays open in a read-only state: your projects, assessments and reports are all still there to open and download, you just cannot start new work until you subscribe again.

Payment is by card through Razorpay, billed in USD. Where local tax law requires it, tax is calculated and added at checkout from your billing address (GST in India, VAT in Europe and the UK, and the equivalent elsewhere), and every invoice is itemised.

Anyone who has to produce an IEC 62305 lightning risk assessment, for their own buildings and sites, or for clients. That includes in-house engineering, facilities and safety teams at data centres, hospitals, telecom, industrial and other high-value sites, alongside the electrical and MEP consultancies, lightning-protection specialists and auditors who issue assessments for others. Start a 14-day free trial to see how it fits your work.

IEC 62305 is the international standard for protection against lightning. Part 2 (IEC 62305-2) defines the risk method: you assess a structure and the engine builds the nine risk components, resolving your lightning risk against the tolerable limit, plus the frequency of damage to internal systems. The how it works page walks through the method in detail.

Each firm's workspace is kept separate, and we handle personal data under the law that applies to you: the GDPR or UK GDPR in Europe and the UK, India's Digital Personal Data Protection (DPDP) Act in India, and the equivalent regime in your market. Our privacy policy sets out what we collect and how it is used.

Lumex is used wherever IEC 62305-2 or a national adoption of it applies, which is most of the world outside the United States: India, the Middle East, Africa, South and Southeast Asia, Australia and New Zealand, Europe and the UK. The engine implements Edition 3.0 (2024), the same technical text those countries publish under their own numbers, such as IS/IEC 62305-2 in India, AS/NZS IEC 62305-2 in Australia and New Zealand, and EN IEC 62305-2 in Europe. You select the jurisdiction before you compute, and Lumex applies that country's national rules rather than the IEC defaults alone. Billing is in USD by card.

Edition 3.0, published in 2024, adopted nationally across most of the world: IS/IEC 62305-2 in India, AS/NZS IEC 62305-2 in Australia and New Zealand, EN IEC 62305-2 in Europe, BS EN IEC 62305-2 in the UK, and national adoptions across the Middle East, Africa and Asia. The engine reproduces all three Annex F worked case studies to the published figures. It computes the nine risk components per zone and the four frequency-of-damage components, against the tolerable limits. Where your jurisdiction sets its own values instead of the IEC defaults, the report says so in the footer.
