Avoid costly mistakes in linear lighting with LIANNA’s unparalleled flexibility

Costly mistakes in linear lighting are common – inefficiencies, gaps, uneven illumination and poor reliability that drain time and money. LIANNA prevents them. With unmatched flexibility, efficiency, and adaptability, it delivers flawless performance for both industrial and retail applications.

Make the right choices with confidence

Every project faces a trade-off: should you prioritise maximum efficacy or lowest BOM cost?

Your customers will compare alternatives anyway. If you don’t guide that comparison, they’ll do it on their own terms — and the result may not favor you. That’s why we’ve laid out the facts clearly: how LIANNA outperforms standard solutions in both efficacy and cost.

Which priority matters most in your project
– the highest lm/W or the lowest BOM?

LIANNA gives you the freedom to succeed either way. Whether your goal is to push lm/W performance to the limit or to build the most cost-efficient luminaire, LIANNA adapts – without sacrificing quality or reliability.

The table below shows LIANNA side by side with 1-row and 3-row IP solutions, including the LED types used in each scenario.

Priority	Risk if wrong choice	LIANNA IP advantage	1-row IP	3-row IP

Maximise efficacy	Lower output → wasted energy & higher long-term costs	187 lm/W (+26 lm/W vs 1-row) at lowest cost (high-efficacy LED) ✅	161 lm/W baseline (high-efficacy LED)	~187 lm/W but +20 % cost (high-efficacy LED)
Minimise BOM cost	Cheap components → poor efficiency & dissatisfied clients	~180 lm/W with –9.4 % BOM vs 1-row IP (standard LED) ✅	161 lm/W, higher cost (high-efficacy LED)	~187 lm/W with +16 % BOM (standard LED)

So actually, there is no real choice to make – or at least no need for compromises. Whether you aim for maximum efficacy or the lowest BOM, the winning solution is always the same: LIANNA – delivering top performance in a compact 40 mm form factor that 3-row solutions cannot match.

Shape the perfect light

Lighting is more than numbers – it defines how people experience spaces. The wrong beam angle can lead to wasted energy, poor visibility, or dissatisfied clients.

With LIANNA’s wide range of symmetrical (110°, 90°, 60°, 30°) and asymmetrical (ZT25, Z2T25, O) beams you can achieve exactly the result you need. From uniform illumination in high-bay warehouses to precise aisle lighting in retail, LIANNA adapts to every application.

See how the different LIANNA beams shape the space below making it easy to choose the perfect distribution for your project.

110° beam – low-bay installations: Extra-wide coverage designed for open-plan areas and supermarkets with low ceilings.

Lengths that fit your design

Compromises in length often mean visible gaps, broken aesthetics, or restricted design freedom.

LIANNA solves this. Its versatile two-row lens design is available in virtually any desired length, in 1-foot increments – even so long that we had to make the video below to show it. It’s one continuous piece, eliminating gaps entirely. Whether the goal is creating long continuous lines of light or shorter, more compact fixtures, LIANNA adapts effortlessly to the application.

We offer all beam types in 4-, 5-, and 6-foot lengths for a seamless, gapless aesthetic. In addition, 60° and 90° beams are available in 2-foot versions that can be used as standalone units or combined effortlessly with longer lengths.

Built for reliability

Failures in harsh conditions can quickly become costly – damaging both projects and trust.

LIANNA protects your investment. Its IP65-rated design eliminates the need for a separate cover glass, delivering robust protection against dust and moisture in a simple, cost-efficient way. See how straightforward the process is in the video below.

Installation is just as secure: LIANNA’s side-clipping system enables fast, tool-free attachment to aluminium profiles or metal sheets. The result is quick, reliable integration that saves time and reduces risk.
