Trio DUOline 78150107 is a single LED spotlight for the two-phase DUOline track system. Its compact metal head has a block-shaped outline and a pale front face. The matt nickel finish identifies this particular version, rather than the white or black alternatives in the same family.
A light point within a compatible track layout
This is a system component, not a complete track lighting kit. Compatibility with DUOline is therefore the first consideration; a similar silver finish on another track does not establish a match. In a suitably configured installation, the two-phase system allows fittings to be divided into two groups that can be switched or dimmed independently.
The spotlight can be positioned at the chosen point on a compatible track. A joint between the adapter and the head lets you change the direction of the light, with the installation instructions showing a tilt of up to 90°. This is useful when the furniture layout changes but the track remains in place. The manufacturer allows wall and ceiling mounting.
Warm white light and external dimming
The integrated SMD LED is rated at 3.5 W, with 330 lm and a colour temperature of 3000 K. It provides a warm white light point for a living room or bedroom. The number of fittings needed for an entire room depends on its size and the lighting layout: the output of one head should not be mistaken for the output of a complete installation.
Dimming requires an external controller compatible with the fitting and its installation. It is not operated by a button on the spotlight head. The built-in LED also means there is no separate screw-base bulb to select.
Size and visual character
The fitting measures 14 cm high, 5 cm wide and 8.5 cm deep. Compare these dimensions with the clearance between the track and nearby furniture. Its simple geometry and matt nickel finish suit modern, minimalist interiors where the visible track forms part of the room's design.
