Create energy-efficient, healthy lighting. ESY!
LENJA series surface-mounted ceiling luminaires and pendant lights

Versatile applications

From classrooms and offices to retirement homes: Pendant lights and surface-mounted luminaires from the LENJA series are ideal for energy-efficient modernisation of a wide variety of applications, not least due to their high luminous efficacy.

Tunable White variants for energy-efficient Human Centric Lighting
High luminous efficacy of up to 148 lm/W (LENJA CL) or 159 lm/W (LENJA PDL)
Pendant lights with an indirect light proportion of 45 % for harmonious illumination of rooms
Surface-mounted variants with protection type IP44
Easy installation and integration into an intelligent light control system

Sustainable illumination

Alongside Tunable White variants (2700 – 6500 K), the series also includes variants with a fixed light colour (3000 or 4000 K).

In all the luminaires, the backlight arrangement of the LEDs ensures homogeneous, dazzle-free illumination and a long illuminant service life.

Intelligent use of DALI-2

A presence- and daylight-dependent light control allows you to make the most of this extended LED service life.

LENJA's DALI-2-certified driver makes it ideal for this purpose – and it can be combined with Tunable White to create Human Centric Lighting that promotes health and motivation.

Let in the light

Human Centric Lighting (HCL) is the best form of indoor lighting for people. Many studies have proven that its daylight-imitating brightness and colour gradients improve well-being, performance and concentration.

In classrooms, for example, Human Centric Lighting improves learning in the long-term.

Energy-efficient Human Centric Lighting

Tunable White variants in the LENJA series and DALI-2 light control from ESYLUX combine HCL with a flexible luminaire design and especially energy-efficient implementation.

This is because the presence- and daylight-dependent light control offered by SymbiLogic technology reduces the energy consumption of the HCL, making this form of lighting fit for a sustainable future.

SymbiLogic in schools

Children, young people and teaching staff benefit in everyday school life. Results of a study conducted by the University Medical Centre Hamburg-Eppendorf in Germany show:

An increase in reading speed by more than 30 %
45 % fewer errors
A reduction in restlessness by 76 % due to targeted use of dimmed, warm white lighting

Elegant suspended mounting – LENJA PDL

LENJA pendant lights provide an optimal balance of light and shadow through a combination of 55 % direct and 45 % indirect lighting.

An additional module with an integrated FLAT presence detector enables seamless integration into a DALI-2 light control system.

High indirect light proportion of 45 %
High luminous efficacy of up to 159 lm/W
Protection type IP40 prevents insects from entering

Simple surface mounting – LENJA CL

LENJA surface-mounted luminaires offer an alternative with protection type IP44. This level of protection, for example, makes them ideal for changing rooms or other areas with harsher environmental conditions.

High luminous efficacy of up to 148 lm/W
Protection type IP44 enables use in sanitary/side rooms

The simple locking mechanism makes it easy for just one person to install the surface-mounted luminaires.

5-wire cable with 230 V voltage and DALI-2 control line can be flexibly inserted into the housing:

Option 1
Cable entering in the centre (1) or slightly offset (2)

Option 2
Surface-mounted cable entering from the side into the opening (1) and exiting from (2) for through-wiring of multiple light strips.

And flexible control

The cross-manufacturer interoperability and backwards compatibility of DALI-2 open up a wide range of control options for LENJA – for example in combination with a single push button!

An ESYLUX DALI-2 light control system remains the first choice for creating maximum quality of life and ensuring energy efficiency with LENJA: 
From Human Centric Lighting and presence- and daylight-dependent constant light control to a light alarm in hazardous situations, for example.
