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

Lighting projects fail every year – from inefficient, costly luminaires and uneven illumination to unattractive designs and IP breakdowns. Each failure costs thousands and harms your reputation.

LIANNA prevents these risks with a continuous two-row lens available in virtually any length. With multiple beam options optimised for industrial and retail applications, one-click installation, and proven IP protection, LIANNA delivers seamless, flawless, and reliable lighting that keeps your projects performing for years.

Make the right choice, every time

Every project faces a trade-off: should you maximise efficacy or minimise BOM cost?

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

In today’s competitive linear optics market, customers will compare alternatives. That’s why we’ve laid out the facts clearly in the table below showing how LIANNA IP outperforms standard 1-row and 3-row IP solutions in both lm/W and BOM. This is how you win tenders in your favour.

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)

Shape the perfect light

The wrong light distribution 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 lighting outcome you need. From uniform illumination in high-bay warehouses to precise aisle lighting in retail, LIANNA adapts to every application.

Which beam pattern best fits your project?

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

Lengths that fit your project

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

LIANNA solves this with a versatile two-row lens available in virtually any length, in 1-foot increments. Standard beams are offered in 4-, 5-, and 6-foot versions*, forming a continuous piece that eliminates gaps entirely and keeps every luminaire seamless and flawless.

*60° and 90° beams are also available in 2-foot versions, usable as standalone units or effortlessly combined with longer lengths.

Easy click-in, proven IP65 protection

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

LIANNA protects your investment. Its IP65-rated design – achieved with just two sealing gaskets – eliminates the need for a separate cover glass, which typically adds €5 per luminaire and reduces efficiency by 10%. At the same time, it provides robust protection against dust and moisture in a simple, cost-efficient way. Installation is equally reliable and effortless: the side-clipping system locks securely without tools, saving both time and labour.
