We turn a day of spreadsheet work into thirty minutes

Lumex^™ began on a consultant's desk, not in a product meeting. We sat with lightning-protection engineers to learn how the work really gets done, and watched one of them lose most of a day to a spreadsheet. He knew IEC 62305 cold; the standard was never the hard part. The day went elsewhere: dimensions typed cell by cell, coefficients chased across a dozen tabs, one wrong reference quietly pulling the risk off course, then a generic Word template rebranded by hand.

That was the moment the idea landed. The maths is deterministic and already written down in a published standard, yet every firm was rebuilding it by hand and betting on no typos in numbers a client would file. So we built Lumex^™ around one belief: keep the judgement with the engineer, and let the software carry everything around it. Sphera running each standard by its own method, a branded audit-ready report, and a workspace that outlives the assessment.
