The LED track spotlight of the VLF series from Synergy 21, type S21-LED-NB2500020, is a 3-phase spotlight for track systems, specifically designed for integration into modern lighting systems in indoor environments. The device has a power rating of 15 watts and produces a light output of 1550 lumens at a colour temperature of 3000 Kelvin, corresponding to warm white lighting. Light quality is ensured by a CRI value of over 90, providing natural colour rendering. The spotlight features a beam angle of 36 degrees, enabling targeted, focused light distribution. The UGR rating below 5 indicates low glare, making it suitable for applications requiring high visual comfort.

Applications

The spotlight is designed for use in offices, retail spaces, exhibitions, and other indoor environments where precise and appealing lighting design is required. The 3-phase technology allows integration into existing track systems, providing a flexible and modular lighting solution. The swivelling and tilting mounting (359° and 90°) offers high flexibility in directing the light beam.

Functions and Equipment in Detail

The device features an aluminium housing, which is robust and durable. The housing colour is black, providing a modern and discreet appearance. The spotlight is not dimmable and operates with an on/off driver, enabling simple control. The nominal lifetime is 35,000 hours, indicating high reliability and low maintenance frequency. The optical ambient temperature is 25 °C, ensuring safe operation under normal indoor conditions.

Technology Explained Simply

LED technology ensures high light output with low energy consumption. The luminous efficiency of 105 lumens per watt demonstrates the high efficiency of the spotlight. Power supply is via the 3-phase track, eliminating the need for additional cables or sockets. The IP20 protection rating means the spotlight is protected against finger contact, but not suitable for outdoor use or damp environments.

Compatibility and Accessories

The spotlight is compatible with various 3-phase track systems, including recessed and surface-mounted tracks in different lengths and colours (white, black) as well as DALI-capable variants. Additionally, various beam angles are available as interchangeable lens kits (15°, 24°, 50°) as well as Honeycomb options, allowing light distribution to be adapted to specific requirements. The availability of interchangeable housings in seven colours (white, black, Brushed rose gold, Brushed gold, Brushed bronze, Electroplated titanium, Electroplated nickel) enables individual lighting design.

Mounting and Installation

Mounting is directly onto the 3-phase track, with the swivelling and tilting construction enabling precise alignment of the light beam. Installation requires no additional tools or special skills, as the track already provides the power supply. The dimensions of the spotlight are 162 mm × 163 mm × 55 mm, ensuring a compact design.

Advantages in Operation

The spotlight offers high light output with low energy consumption, leading to reduced operating costs. The long lifetime of 35,000 hours and high switching cycle durability of 50,000 cycles ensure reliable and low-maintenance operation. The flexible orientation and availability of various light distributions enable customised lighting solutions for different requirements.
