Pricing and plans
How much does Lumex™ cost?
Plans are priced per seat, with unlimited projects, assessments and report downloads, so you pay for the team, never per report. You buy either plan online, monthly or yearly. The current prices are on the pricing page.
Is there a free trial?
Yes. Professional starts with a 30-day free trial with 3 seats, 3 clients, 3 projects, 5 assessments and 50 Lumi messages a day for each person. Enterprise has no trial. A free trial needs no card. Your paid plan starts when you pay for it. Paying ends the trial that day. Reports made during the trial carry a watermark, which goes once you subscribe. Reports made under the founding member offer carry no watermark. There is no permanently free plan.
How do I get started?
Create an account from the Get started button, choose a plan and start your free trial. No card is needed. Your workspace opens straight away. Create a project, pick the standard for its first assessment and work through the steps to a result and a report. You can invite colleagues and give each one a role as soon as the workspace is open.
Can I see a sample report before I sign up?
Yes. The pricing page has a sample PDF for each standard: one for IEC 62305-2:2024, one for NFPA 780-2026 and one for AS 1768:2021. Each is a worked example made in Lumex™, so you can read the figures, the working and the layout before you start a trial. The NFPA 780 and AS 1768 pages link to their own samples too.
Do I need to install anything?
Can I get a walkthrough before I buy?
Yes. Book a demo, pick a free time, and a 30-minute Microsoft Teams call is booked for you. Someone from our team runs an assessment live in Lumex™, from the first input to the finished report, and answers your questions as you go. If you would rather explore on your own, you can skip the call and start the free trial straight away.
Who it is for, the standard and your data
Who is Lumex™ for?
Anyone who has to produce a lightning risk assessment, for their own sites or for clients. That includes electrical and MEP consultancies, lightning protection installers and auditors, and in-house engineering, facilities and safety teams at data centres, hospitals, telecom, industrial and other high-value sites. A team of one works the same way as a large firm, with each person's role set in the workspace.
Which standards does Lumex™ support?
Three, each run by Sphera with its own standard's method: IEC 62305-2:2024 (Edition 3), used across most of the world; the Annex L risk assessment of NFPA 780-2026 for the United States; and AS 1768:2021 for Australia. You pick the standard when you start an assessment, the inputs follow that standard, and the report cites it throughout. Every plan includes all three.
Which regions does Lumex™ serve?
Where is my data stored, and how is it protected?
Your workspace data is stored on Microsoft Azure in India. The model behind Lumi, which answers questions, drafts report narratives and reviews drafts, runs on Azure in the United States. Data is encrypted with TLS 1.2 or later in transit and AES-256 at rest, and each workspace is kept apart from every other, so one firm never sees another's records. Roles decide what each person can open or change. Our privacy policy has the detail.
Which privacy laws cover my data?
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 Act in India, and the equivalent law in your market. Where data from Europe or the UK is processed in India or, for Lumi, in the United States, we rely on the Standard Contractual Clauses. Our privacy policy sets out what we collect and why.
Can I export or delete my data?
Yes. An Admin can download the whole workspace from Settings as one ZIP file of every report and its images. An Engineer can download the same for the projects assigned to them. To have personal data erased, follow the steps on the data deletion page. After an account closes we keep its workspace data for 90 days, so a mistaken closure can be undone, then delete it, except records the law makes us keep, such as tax invoices.
