LUBAN Led Signal Tower Stack Lights, Industrial Warning Column Lamp, Andon With Rotatable Base, Steady/Flashing Switchable, 12V 24V DC (3-Layer, With Buzzer)

There was nothing I didn't like about this unit. Once we figured out how to get it apart, the Green didn't budge but we managed to get a flat blade screw driver inside to change the switch from flash to constant. Then everything was fine. Like with all buzzers we had to put tape over the hols to quieten it down. I machined a dent into the base as I was passing the wires through the side not the bottom, no big chore. But now when the machine comes on it lights up green, when the Laser armed the Red light fires up and when there's an anomaly needed attending the orange/amber light flashes and the buzzer sounds. Solid bit of kit and should last for years. Oh and the wiring flummoxed me as the only diagram is on the side of the lamp, no other instructions but when adding it to the Rueda controller wiring diagram it made no sense to my brain, but my partner insisted that was correct way to go, I went for it closed my eyes and hit the power and low and behold it worked so I need to understand my Rueda controller really... lol Josh

It work well for a side project that need a light sign in the motion of work. It play well with the PLC on the machine.

Top Verarbeitung, bei Nacht oder tagsüber ohne Gegenlicht gut sichtbar, bei Gegenlich ist es allerdings nicht hell genug, und nur schwer erkennbar, welche Farbe leuchtet. Zum Glück ist der Warnton absolut unüberhörbar, so daß die beiden Geräte, die ich gekauft habe gut als Ampelanlage an meinen Automatischen Toren geeignet sind. Ich habe übrigens die Version mit 12 V im Einsatz.

The base has to be attached to the lights. I found it easiest to remove the screw that holds the two halves of the base together in order to feed the wires through it. The lights can then be screwed onto the base. The light looks well made. It has a number of features that makes it easy to use. It uses 12V or 24V DC. Polarity does not matter, so it can be wired in NPN or PNP configurations. This means the common wire can either be positive or negative voltage. Each light has an internal switch so you can switch between flashing or solid light. The lenses can be removed individually by twisting off, but it is easiest to just twist off the green lens and then remove all lenses as a unit to get access to the internal switches. I tested the light with both 12VDC and 24VDC and the brightness appeared to be about the same. The audio alarm is not as loud as a smoke alarm but it is very noticeable. The only negative is the brightness which could higher. But it is fine for many indoor applications.

Die Lampe ist in Ordnung und funktioniert wie es in der Beschreibung steht!
