OPERATING INSTRUCTIONS

LED DESK LAMP CL-4R-20

___________________________________________________________________________

1. General information

The CL-4R-20 is a 20-

inch LED gooseneck

lamp for the lighting of

mixing consoles and

other devices in the

audio / video area.

The very robust lamp

head (aluminium, CNC

milled) and the use of a

high-quality metal

flexible hose meet the

special requirements for

professional use. Highly

selected LEDs (CRI>90)

and a diffuser for optimal light distribution create a particularly comfortable working

environment and ensure maintenance-free operation. The lamp can be dimmed either

analogue in the voltage range of 3-12V, or with PWM. Due to the integrated bridge

rectifier, the polarity of the operating voltage can be neglected. Operation is therefore

also possible with AC voltage.

With regard to a blue light hazard when using LEDs, the photo-biological

measurement of the lamp according to EN 62471:2009 resulted in a classification

in the risk group RG0 (no hazard).

2. Operation / functions

The lamp is designed for a nominal voltage of 12V DC and is therefore compatible

with most sound and light control desks available on the market.

In order to achieve a very long service life for our lamps, the LEDs are only loaded

with 40% of their maximum current. As a result, the expected service life of the LEDs

corresponds to more than 50,000 hours and allows long and maintenance-free use.

Please make sure that the flexible hose (gooseneck) is not bent too sharply.

Overstretching causes irreversible damage. The bending radius must not be less

than 6 times the diameter of the flexible hose!

(6 x 8 = max. bending radius R=48 mm) After opening the connector housing, the

orientation of the XLR- PIN insert can be adjusted in 45° steps to the respective

mechanical properties of different consoles. Under no circumstances should solvent-

containing cleaners be used for cleaning the lamp. Please avoid excessive wetting of

the flexible hose. For further information, please refer to the diagrams under points 4.
