Heat Management

The patented design requires 50% less material, making the overall LED module lighter and more efficient.

The shape and layout of ELR’s innovative heat sink promotes passive, natural convection in a small form factor, eliminating the need for active fans or diaphragms that are prone to wear and making unnecessary noise.

Colour Quality

LED modules are available in a variety colour temperatures: warmer white with a CCT of 2200K and 2700K; warm white at 3000K; neutral white at 4000K and cool white at 5000K.

Utilising advanced and systematic LED binning techniques, ELR ensure the white colour balance between LED modules, which are tightly controlled at 3-step MacAdam ellipse binning for consistent white light and aesthetically pleasing lighting effects.

All ELR LED modules offer an excellent colour rendering index (CRI) of Ra~85, with optional further increase to Ra~95 using ProART models. 


An expansion from ELR’s technology breakthrough, flexiK LED modules are pre-set at preferred colour temperatures by increments of 100K, ranging from very warm white of 1800K up to very cool white of 6500K. With flexiK, preferred colour temperatures can be fulfilled to obtain the desired ambience.


tuneWHITE™ is ELR’s on-demand colour temperature adjustment system. With a tuning range from warm, halogen-like 2700K through to cool 6500K, flexible room atmospheres can be easily achieved. Also with ProART CRI~95, tuneWHITE™ LED modules to offer an excellent colour rendition performance.

tuneWHITE™ is interfaced to a DALI control system and is compatible with the latest DALI part 209 directive. This allows the tuning of colour temperature with a single DALI address for simplified installation and configuration.


The WARM DIM effect has been integrated into our integrated NEST, and PRO LED modules with dimming performance to <1%. The colour rendition performance is the greatest at ProART level of CRI~95.

The WARM DIM technology provides CCT tuned from warm white of 2700K or 3000K towards the warmer 1800K, and is available within 35Nest, 50Nest, 50P and 100P LED module series. Beam angle selection is from 20°, 35° and 60°.


Optics used in all ELR LED modules are manufactured from premium grade PMMA or polycarbonate polymers that offer exceptional performance without degradation over the life of the component.

A range of beam angles is available to provide suitable illumination for a wide variety of applications, from variations of narrow to a wide beam with excellent uniformity and rotationally symmetrical light distribution to asymmetrical wall washing applications.

While maintaining the performance of providing accurate light distribution and chromatic consistency, the ELR X-Beam maximises luminous efficiency further within luminaires, giving near perfect light output ratio (LOR).


NEST fully expands the LED module thermal surface to the outer layer of its entire body, enhancing better heat transfer from module to ambient environment and most importantly, maintaining its performance within the expected lifetime of 50,000 hours. The centre of the NEST LED module, which is normally threated as the “heat-sinking” element that temporarily stores heat before being transferred to the surface and ambient environment, is designed to perform most effectively without the waste of space. With its unique design concept, extra space is allocated to either have the LED driving electronics flexibly placed compact together with the LED module, or as an external LED driver.


ATePS™ is an intelligent combination of superior LED engine, electronics and heat management firmware. The heart of ATePS™ is ELR’s proprietary thermal feedback system. In the event of abnormally  high ambient temperature conditions, ATePS™ actively regulates the LED engine temperature through algorithmic fine-tuning without any user intervention, maintaining maximum possible light output without sacrificing the service life of the LED engine.


Light oscillates, but normally at very high frequencies not noticeable by the human eye. Therefore our instantaneous perception is a continuous ray of light. Just like TV or computer screens having their own defined oscillating refresh rate, otherwise known as frame rate.

Nowadays with our power grid running at 50Hz or 60Hz, artificial light is prone to oscillate at 100Hz or 120Hz. Since this oscillation frequency is low, it’s easier for the human eye to perceive a stroboscopic effect that may cause discomfort and health concerns to some. In order to provide comfortable light experience, the ComfyEYE aspect embedded in ELR LED driver technology minimises light flicker percentage, which is the measurement of peak-to-peak contrast of light output. By reducing light flicker percentage below certain threshold at lower frequencies, ComfyEYE eliminates stroboscopic effect and prevents our eyes from being strained to perceive light as continuous.

Eye Response Dimming

The human eye has a non-linear response to the brightness of light. The adaptation of our pupils to bright light greatly differs when being in a darker environment. It is scientifically proven that this is a logarithmically response. ELR LED drivers provide dimming curves to match the human eye response for maximum comfort and a luxurious feeling of the dimming effect.

Multiple Dimming Protocols
ELR provide LED driver selections with different dimming protocols to fit different applications.
