Stack Lights, Industrial Signal Tower with Rotatable Base, Steady/Flashing Light Switchable, 12V/24V DC (3-Layer, No Buzzer)

I looked at the all-steel versions for $100+, but for my application, this low cost alternative worked well. Nice bright LEDs and no problems.

Works as well as ones costing five times as much.

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.

This is very easy to see from all angles. Build quality seems good. It is all plastic, so mount it where it won't get bumped and should last a long time. It has 4 wires, 1 for ground and 1 for each color.

This worked out very well for our church. We're doing live worship broadcasts which sometimes include a short video. The light is handy for letting the worship participants know when the video is playing, almost over, and ended. I coupled it with a small remote control device and 12 volt power supply to operate it from behind a wall where the computer and video recording software is located.

These worked for my application. I’ve been designing automated equipment for the company I work for currently, and we are on a budget. So these will beat the price of pretty much everything else out there. However, these are made of cheap plastic. Don’t expect them to hold up well to abuse. But hey, they’re stacklights. They shouldn’t be experiencing a ton of abuse, in a normal application anyway.

Works great, used it on a machine to indicate different states. The buzzer is not consistent though and is on a few second timer. Not sure if this was in the description but might be good to know.

I like that the common can be positive or negitive. With that said, It worked perfectly for my need. It works with my rgbw/4channel white LED wifi controller.

Works as intended… looks great… used it for a status indicator on our outdoor sauna

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

Eingesetzt ein einem Zugangssystem erfüllt die Ampel alle Voraussetzungen: Leuchtet hell, der Alarmton ist weit zu hören, abklappbar und stabil. Kann via Relais mit GPIOs vom Raspi angesteuert werden

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.

Sehr schönes Produkt entspricht genau der Beschreibung. Einfach zu installieren und anzuschließen.
