Made for lighting

Not a generic CRM with a lamp icon.

Beam angles, lumen packages, IP ratings, target lux, floor plans. LediCRM understands the things a lighting business actually sells.

Photometrics

Every luminaire, with its real light distribution.

Attach the manufacturer’s IES or LDT file to a variant. LediCRM reads it for you — intensity distribution, lumen output, beam angle — and checks it against the datasheet before it reaches a quote.

  • Light distribution curve on every variant
  • Warns when the file and the datasheet disagree on watts or lumens
  • Curve and photometric summary printed on the datasheet PDF

Lighting design

From floor plan to luminaire layout.

Upload a DXF or DWG plan, mark the rooms, pick a room type and let LediCRM place luminaires against the target lux — then check the result point by point.

  • Draw any room shape, not just rectangles
  • Room type sets the target lux and the starting luminaire
  • Heat map, average lux and uniformity for every room
  • Multi-room PDF report with the luminaire bill of materials
  • Or ask the assistant to design a room — you confirm before anything is saved

A pre-sizing tool. Final designs still call for a full calculation in software such as DIALux or Relux.

Quotations

Straight from the design into a priced quote.

The luminaires in a lighting project become a draft quotation for the right customer in one click, priced from your own catalogue. Or import a BOQ and match it line by line.

  • Draft quotation created from the project’s luminaires
  • PDF catalogue import with an editable preview
  • BOQ matching against your own range
  • Revision history kept against the customer

What it does

Everything between the catalogue and the quote.

The daily work of a manufacturer, distributor or project company, in one system.

PDF catalogue import

Drop in a supplier catalogue. Products, specifications and images are extracted in parallel and land in an editable grid. Nothing is saved until you approve it.

One product, many SKUs

Variants that share an appearance sit under a single parent. Images live on the parent; every variant keeps its own SKU.

BOQ matching

Load a project bill of quantities and match specified items against your own range, line by line.

Quotations

Build a quotation from catalogue products, from matched BOQ lines or from a lighting design, with revision history against the customer.

Plain-language search

Ask for “recessed downlights, 3000 K, IP44, under 15 W” and get products back, not a keyword match.

Customers and projects

Companies, contacts, activities and tasks, structured around lighting projects rather than generic deals.

All features

How it works

From a first estimate to a sent quote.

1

Size the room

Start with the free calculator: lumens, luminaire count and power for any room, in seconds.

2

Build your catalogue

Upload the supplier catalogue and IES/LDT files. Review the extracted grid, then commit it.

3

Design and match

Lay out luminaires on the floor plan, or match the project BOQ against your own range.

4

Send the quote

Turn the design into a priced quotation for the customer and track it to a decision.

Inside the app

The actual screens, not a mock-up.

Captured on a demo account: the assistant on the dashboard, the catalogue import, BOQ matching and the quotation list.

Trust

Your pricing and customers stay yours.

An assistant that can reach your commercial data is only useful if you can say exactly what it is allowed to touch. Here is the arrangement.

Hosted in the EU

Account data and customer content are stored in Frankfurt, Germany, and encrypted in transit.

Tenant isolation

Every record carries a tenant id, enforced on the server. One account cannot read another’s data.

A read-only assistant

The assistant reads through a database user that cannot write. Any change it proposes waits for your confirmation.

Not training data

Content sent to the AI features is processed by Anthropic as our sub-processor and is not used to train models.

Two plans, a 14-day trial, and the free calculator stays free.
