Tower Stack Lights, Industrial Warning Signal Lights Tower Lamps Column, Factory Workshop Safety RGB Signal Indicator, LED Andon Lights (24V, 3 Layers)

My husband has a high-stress job managing an IT data center, and he and my daughter love to build and program projects. As a gift / idea for a new DIY fun project, I gave them the Nxtop Red Sign Mushroom Emergency Stop Button (https://www.amazon.com/gp/product/B083BPRGRP) and Nxtop DC 24V Industrial Signal Lights (https://www.amazon.com/gp/product/B07DN59CZ6). They are pairing these with an Arduino setup, so that my husband and his employees can have a fun way to mess around during meetings and such. I realize these are designed for production facilities, but they’re also fun to build into customized silliness. 😉As the parent of kiddos with autism, there are causes near and dear to my heart.

This is a great value for a stack light. This unit came with an annunciator which isn't reported in the description. There was no documentation included. The wiring diagram on the box doesn't match the actual wire colors of the unit. You should test with a DMM before connecting the wires to a power supply but this is what I found.red wire > red ledyellow wire > yellow ledgreen wire> green ledpurple wire > annunciatorgray wire> 24VDC RTN or commonThe annunciator is sufficiently loud but I find the frequency too high. I may change out the annunciator for a lower frequency buzzer. The sound level was measured at 95dBA with a peak frequency of around 3.2kHz.

Low power usage. VERY loud buzzer. The stalk is mounted on a ball joint with springs, so it has some give. if hit/bumped. No wiring diagram. But pretty easy to figure out.red = redyellow = yellowgreen = greenpurple = buzzergray = common (-)

Out of the box, this is a pretty good looking light. For me it's just the right size, not too big, not too mall. It is well made. Although all plastic it seems pretty durable. There are no instructions, argh, but there is a wiring diagram on the box. But the only english are the wire colors. You'd think if they want to sell to english speaking people, they would put better english in the product.Even though there is no instructions, it's very simple to figure out. Best yet, the wire colors match the color of each light. Except the purple which is the buzzer. So you simply hook up your ground to the gray wire and the hot to the color you want to light. Works exactly as it should. Lights are bright enough and easy to see. The buzzer is quite loud and annoying if you ask me. Guess that might be good, depending on your use.I picked this up to use on my dust collector. I am automating the system and will use to to show if the collector is on, and the yellow and red will tell me when the barrel is getting full, or is full. That is the plan anyways. But this will be perfect for that application. Plus it has a good mount.Really like this light and if they actually put some effort into proper instructions, including english, it would be a 5 star product. Would still recommend though, I do like it.

I got the Nxtop DC 24V Industrial Signal Light to work with a small relay board controlled by an Arduino - which is turn controlled by a data collection PC via USB. A 24V source with a 5V buck put it all together. I use the green light is to indicate when a machine tool is in use (and an operator is clocked into the job). I use red to indicated when the machine is not in use. Orange is implemented as a slow or fast flashing light (the flashing controlled by the Arduino), indicating if the software thinks the machine is running, but there is no job (slow) or if there is a job selected, but the machine isn't running (fast). I haven't decided if I will use the buzzer.Using the stack light was pretty straightforward. I will say that it works well, but I'll also say that it's not as bright as I'd prefer for a factory floor. However, at about $22, it's a solid value. The mount is not as flexible as some alternatives, so that's something that may affect your decision (if you have limited mounting points). Conditionally recommended
