What is the difference between an articulated arm and a flex arm?

An articulated arm holds its position through springs and joints and carries larger heads as well. A flex arm is a bendable gooseneck that can be shaped freely and is meant for small, light heads.

How is the luminaire fixed?

Articulated arm, table clamp, magnetic holder and base are available. Table clamp and magnetic holder need no drilling, and the base can simply be moved across the work surface.

What does tunable white offer?

Tunable white lets you shift the light colour between warm and cool white. That helps at stations with changing visual tasks. For integration into a central lighting control there are DALI dimmable luminaires as well.

How much light is sensible?

Luminous flux runs from 180 lm to 14400 lm at a power input of 2 W to 125 W. Low values are enough for a flex arm light directly above the workpiece, high values light a whole workbench.

Which colour rendering do I need?

Ra 90 is the choice when colours and surfaces have to be judged reliably, for example in visual and final inspection. Ra 80 is enough for general assembly work.

Workplace lighting

Articulated and flex arm lights

Articulated and flex arm lights put the light where the work happens: at assembly and inspection stations, at workbenches and on machines. The head sits on a spring-balanced articulated arm, on a flexible gooseneck, on a table clamp, on a magnetic holder or on a base. Luminous flux runs from 180 lm to 14400 lm at 2 W to 125 W, light colour from 3000 K to 5700 K, plus luminaires with tunable white. Colour rendering is Ra 80 or Ra 90.

How to choose Articulated and flex arm lights

What matters when choosing: properties, comparison and typical applications.

Selection criteria

Criterion	Values in this category	What to look at
Mounting	Articulated arm, table clamp, magnetic holder, base	Table clamp and magnetic holder need no drilling and can be moved.
Luminous flux	180 lm to 14400 lm	Low values for a flex arm right above the workpiece, high values for a whole bench.
Power input	2 W to 125 W	Input rises with luminous flux and luminaire size.
Light colour	3000 K, tunable white, 4000 K, 5000 K, 5700 K	3000 K reads warm, 5700 K cool and high in contrast; tunable white covers both.
Colour rendering	Ra 80, Ra 90, Ra 70	Ra 90 for colour judgement, Ra 80 for general assembly work.
Control	Tunable white, DALI dimmable, dimmable, HF switching	DALI suits a central lighting control, HF switching reacts to movement.
Protection class	IP20, IP65, IP67, IP40	IP20 is enough indoors and dry, IP65 and IP67 handle splash water and coolant.
Beam angle	10°, 30°, 90°, 100°	A 10° spot for detail work, wide angles for even area lighting.
Supply voltage	100-240 V, 12-40 V, 110-230 V, 22-26 V	Mains operation or extra-low voltage from the machine control.
Manufacturer	Glamox, Waldmann, LED2WORK, Starlight	Series range from Motus and FREE-F2100 through TANEO to ROCIA.focus.
