Luban 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.
