Light + Building 2026
Frankfurt am Main.

What Light + Building is, in two lines

Light + Building is the world’s leading trade fair for lighting and building services technology: the place where lighting design, electrical engineering, home and building automation and smart/connected solutions all come together under one roof. It is held every two years (even years, in March) at Messe Frankfurt and is reserved exclusively for professional visitors. The 2026 edition closed with 1.927 exhibitors from 49 countries and 144.767 visitors from 143 countries, with a 95% visitor satisfaction rate: numbers that say only one thing, namely that practically the entire supply chain passes through Frankfurt.

The operational point is simple. At a fair of this scale you don’t sign at the stand: you collect contacts that, in the construction and electrical sector, mature into specifications, tenders and orders over the following weeks and months. That is why it matters less how many business cards you collect and far more how you handle each contact right afterwards, while the memory of the conversation is still warm.

What to exhibit, where to exhibit

The exhibition grounds are large and split by product logic, not by nationality. Halls 3.0-12.1 are organised by product category, with two big souls:

• East area — lighting: technical and decorative luminaires, lighting design, lighting components. This is the cluster that draws architects, lighting designers and specifiers.
• West area — electrical engineering and building automation: home and building automation, electrical installation, safety, energy. This is the cluster that draws installers, system integrators and building services designers.

Practical positioning tip: before you even think about stand design, understand which side of the grounds your customer walks through. A maker of decorative luminaires presenting itself in the right mood in the East speaks the language of those who look for aesthetics and rendering; a supplier of KNX, sensors or electrical panels in the West has to demonstrate integration and reliability. If your product straddles the two worlds (for example connected, controllable lighting), choose the hall based on who makes the purchasing decision, not on how you classify the product internally, and use the app’s floor plan to work out in advance who your stand neighbours are.

Visitor profile

The Light + Building audience is almost entirely B2B and technical. The realistic mix to prepare for:

• Architects and lighting designers (~20-25%): they look for rendering, aesthetics, datasheets; often specifiers rather than direct buyers, but decisive in the specification.
• Designers and engineers in building services, electrical and construction (~20-25%): they assess integration, standards, performance; they think in terms of projects and tenders.
• Installers and electrical-sector contractors (~20%): they buy per order, want availability, easy installation, support.
• System integrators and smart home/building specialists (~10-15%): interested in interoperability, protocols, scalability.
• Distributors, wholesalers and retail (~10%): they think in terms of catalogue, margins, logistics.
• Industry and facility / property management (~5-10%): a TCO lens, energy efficiency, managing the building portfolio.

Two things matter for whoever runs the stand. The first: seniority is high and very international (around 75% of exhibitors are from abroad, visitors come from 143 countries), so you often have the person who decides or who specifies in front of you, not someone collecting flyers. The second: the same badge can hide wildly different roles. Telling a specifier from a buyer from an installer straight away completely changes the follow-up, and that is exactly the kind of information you need to capture on the spot, not reconstruct from memory three weeks later.

How to prepare in the 4 weeks before the event

Week -4: message audit

Review what your stand promises. At Light + Building different worlds coexist (the aesthetics of light and the engineering of building services): a claim that works for an architect is noise for an installer. Define two or three distinct messages per segment and decide who you really want to attract. Also clarify what you are NOT: it helps your staff avoid wasting time on off-target contacts. This is also where the list of qualifying questions comes from.

Week -3: the stand operating playbook

Put in writing who does what: who welcomes, who runs demos, who qualifies, who records the contact. Establish how you hand a person from one set of hands to another without losing the thread of the conversation. Over six days of fair at these volumes, a stand without a script burns leads simply because nobody knows who is supposed to record what. Also define the exact moment a contact is “saved” and by whom.

Week -2: the 3-question qualifying form

Keep qualification short and brutal, three questions that genuinely change the follow-up. For Light + Building these work well:

1. What is your role on the project? (specifier / designer / installer / buyer / distributor)
2. What is your timeframe? (project under way / imminent tender / technology scouting)
3. What do you need as a next step? (samples / quotation / datasheet / local contact)

Three sharp answers collected at the stand are worth more than half an hour of chatting reconstructed from memory the following week.

Week -1: CRM integration

Decide before the fair where the contacts end up, not after. The goal is for every lead to land directly in the CRM with an event tag (“Light+Building 2026”), the answers to the three qualifying questions and a voice note from whoever spoke with the person. This is where the Linkly logic comes in: you capture the contact, enrich it with company data, qualify it on the spot and have it arrive in the CRM already prepared, without the Excel sheet to retype back home. Find out how Linkly works.

Is the official Light + Building app worth it?

Yes, it exists and it is useful: the Light + Building Navigator is the free official app (iOS and Android). It does some things well:

• exhibitor and product search with filters;
• hall floor plans with stand details and quick finder;
• events and conference calendar;
• favourites watchlist;
• badge QR scanner to import contacts;
• works offline too.

It is perfect for finding your way around and for the visitor. But it has to be said honestly what it does NOT do for you as an exhibitor: it does not export leads into your CRM in a structured way, it does not enrich contacts with company data, it does not qualify anyone, it does not build the follow-up, it does not give you a concise report for management. It is also a fair app, which changes from edition to edition: you build your sales process on top of it and you find it different two years later.

In short: the official app helps you experience the fair, but the contact capture system is better off being your own. That is exactly the piece Linkly covers, with the chain capture → enrichment → qualification → follow-up handled by agents that work on the contact the moment you save it. See how Linkly works.

What to do during the 6 days of the fair

Day 1

Opening and calibration. Traffic builds, but this is the day to tune the stand: check that the QR scanner and the qualifying flow work, align the staff on the three questions, fix the message if you see it attracting the wrong audience. Better to sort it now than on the third day.

Day 2

Things get into full swing. Designers and specifiers with real projects in hand start arriving. Keep qualifying discipline high: every valuable conversation has to be closed with the contact saved and the three data points collected, before the next person arrives.

Day 3

Often the decision-making peak day. This is the day when the hottest contacts pass through and when it is easiest to lose one in the chaos. Concentrate your best people and your most important demos here; do a quick mid-day check on leads already recorded.

Day 4

Traffic still full. Use the evening break for a first clean-up of the leads: who is genuinely hot, who needs calling back immediately, who is just scouting. Starting to sort now saves you days later.

Day 5

The pace eases slightly but the quality of contacts often rises: those who come specifically at the tail end of the week usually have a precise reason. A good moment for long conversations and for closing post-fair appointments.

Day 6

Closing day, lower traffic. Make the most of it for the last targeted conversations and, above all, to close the database: every lead tagged, qualified and ready to go. Whoever leaves Frankfurt with the contacts already in the CRM has won the fair; whoever leaves with a stack of business cards starts to lose it.

What to do in the 7 days after the fair

This is where the ROI is decided. The principle is response speed: a contact followed up within 24 hours is worth far more than the same contact called back two weeks later, when they have already spoken to three of your competitors.

• Within 24 hours: a personalised message to the hot leads. Genuinely personalised, citing what you talked about at the stand: this is why you need the voice note or the qualifying answers saved on the spot.
• Within 7 days: send what you promised (samples, quotation, datasheet) and structured contact to the warm leads, segmented by role and project timeframe.
• Within 14 days: a second touch for those who did not reply, with a different angle (a use case, a project reference, the local contact).
• Within 30 days: a cold review. What moved, what entered the pipeline, which contacts to close as unqualified. It is also the time for the honest report to management on the fair’s real performance.

With a system like Linkly this sequence does not live in the salesperson’s head: the leads are already in the CRM with tag, qualification and note, and the follow-up starts while the memories are still fresh.

Practical FAQ

How much does it cost to exhibit at Light + Building?

The cost depends mostly on square metres and stand build. As an order of magnitude for Messe Frankfurt, between bare space rental, stand build, technical services, staff, travel and logistics you easily start from a few tens of thousands of euros for a small stand and it rises quickly for prominent positions. Always ask for the up-to-date price list and think in terms of total cost, not just space rental.

Which is the best day?

For the most decision-making contacts, the central days (around the third day) are usually the peak. Closing day has less traffic but often more targeted contacts. The first day serves to tune the stand more than to generate volumes.

When is it best to register as a visitor?

In advance. The fair is reserved for professionals and registering online before the event avoids queues and gives you access to the floor plan, the agenda and the Navigator app to organise your visits. If you have customers you want to see at the stand, set the appointments beforehand, don’t rely on a chance encounter among the halls.

Do you really need a dedicated app if the official Navigator already exists?

The Navigator is great for finding your way around, but it does not run your sales process: it does not bring leads into your CRM in a structured way, it does not enrich them and it does not build the follow-up. For that you need your own system, one that stays the same from one edition to the next.

Is there an alternative to collecting paper business cards?

Yes, and that is the point. Instead of piling up cards and badges to retype by hand after the fair, with Linkly you capture the contact, enrich it, qualify it on the spot with the three questions and have it land directly in the CRM with an event tag and a voice note. The difference is not cosmetic: it is the speed at which the follow-up starts. See how Linkly works.
