Height adjustment LIGHTtune 3

LIGHTtune 3 came onto the market in 2020, initially designed as a height adjustment LIGHTtune 3 /3 with 3 suspension cables, conceived for larger and heavier circular or disc-shaped lamps.
Now we also offer the LIGHTtune 3 /2 version, with 2 suspension cables, for linear luminaires up to 5 kg.
We are thus meeting the demand and the requirements for electrically and mechanically higher loadable height adjustments.
The sliding contacts and cables make it possible to connect lights with a current consumption of up to 4 amperes.
The optimized sliding contact can lead through up to 4 wires.
Only Teflon-coated coax cables (Ø 2.1 mm) in transparent or black are used
The adjustment range is approx. 160 cm.

A motor-driven variant is under development

The classics

Height adjustments LIGHTtune 1 und LIGHTtune 2

The LIGHTtune 1 and LIGHTtune 2 height adjusters, which have been tried and tested for years, extend the use of suspended LED lights in a way never before seen.
The lamp hangs on a specially developed cable which serves both as power supply and mechanical suspension.
Depending on the model, we achieve adjustment ranges between 105 cm and 160 cm, with light weights of up to 2,5 kg.
When pulling the lamp head downwards, or when lifting the lamp, it stops at the desired height, i.e. it neither falls down nor rises.

We offer 2 versions:

LIGHTtune 1 for suspended luminaires with a 3-wire cable or a coaxial cable.
LIGHTtune 2 for suspended luminaires with two single strands or coax cables.

NEW

LIGHTtune 2 is now also available for use with linear luminaires. As a rule, one of the cables in the canopy is routed out via a rerouter, while the other is routed directly downwards.

The technology

The height adjustment function is made possible by a sophisticated mechanism and cable routing in a compact housing. As an additional extension of the product range, all height adjustments presented here can be adapted to track systems.
LIGHTtune can be installed in a canopy on the ceiling or integrated 'upside down' in the luminaire.
The special cable developed for the height adjustment of the LIGHTtune 1 measures Ø 2.4 mm and contains three strands. The 3rd wire serves as a control line if required.
Alternatively a coaxial cable Ø 2.1 mm can be used.
The LIGHTtune 2 height adjuster is usually operated with 2 single strands Ø 1.3 mm (adjustment range approx. 135 cm), or with two coaxial cables Ø 2.1 mm (adjustment range approx. 105 cm).
The current carrying capacity is 2A and thus covers the power requirements of most LED lights. A Kevlar reinforcement in the cable safely absorbs the weight of the lamp. High-quality gold-plated sliding contacts ensure trouble-free and long-lasting operation.
