Led Signal Tower Stack Lights, Industrial Signal Warning Lights, Column Tower Lamp Andon Lights with Rotatable Base, Steady/Flashing Light Switchable,12V 24V DC(2-Layer, with Buzzer)

I have been using the stack light for about a year in my garage to tell me when to stop when approaching the light sensor. No issues, even comes with a switch inside that you can toggle if you want the lights to flash.

Works great

Bought this for a classroom project and it works pretty well. The lights are bright, but not bright enough to use outside in full sun and be reliable. Little switch on the PCB board to switch between flashing and solid, each color is independent. Both colors can be used at the same time. It's not really industrial grade, but it's also not at that price point. A similar light for a factory machine was over 500 dollars.

These seem to work well. They're not crazy bright but are bright enough to see across the room. I don't think they'd work as well in an outdoor setting from far away, but you'd have to try them out to see. The brightness varies a bit with voltage. They technically light up around 6-7 V, but they're rated for 12-26. At 12V, they draw about 21 mA per light. Current draw increases, along with brightness, up to 16V, where they draw about 40 mA per light. After this, the brightness and current draw are constant up to at least 30V. In other words, at 30V, they still draw 40-42 mA per light, and do not change in brightness beyond 16V. I didn't check past 30V for power supply reasons. I assume the light will still draw 40-42 mA up to the rated 36V.

It's not what I would call industrial strength, but it is a quality plastic unit, and there are multiple LED's per color section so you can see if from all sides. I'm quite happy with it.

Needed to use Google translate to interpret the Chinese labels for the wires.

Don’t use Goof Off or Goo Be Gone to remove the label, since it will melt the plastic. Just use ethanol or isopropyl alcohol.

Worked for a few weeks then stopped! Garbage!

Used this on my dust collection system. Solid green for “armed”, flashing red for “bin full”.

As advertised

Très bon produit

Love these lights... use them with a garage door sensor (beam) that covers two O/H garage doors to know if the cars do not block the O/H door from coming down or up. Unfortunately, the red LED stopped working, so I have to purchase another replacement. They state 100,000 hrs for the life of those LED's which this one definitely did not even come close to.

It’s a little bit light duty But it works, and it can be set to shine continuously or blink you take the cover off and there’s a switch underneath
