LUBANLed Signal Tower Stack Lights, Industrial Signal Warning Lights, Column Tower Lamp Andon Lights with Rotatable Base, Steady/Flashing Light Switchable,12V 24V DC(5-Layer, with Buzzer)

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.

I’m using this in my garage with a 12vdc power brick I had laying around. Got to use my soldering skills after many years to connect it up. I have the brick plugged into a smart plug, controlled by Home Assistant. I use this to light up the lamp when the home security system is armed. So family members coming in thru the garage at night get a visual indication of the state of the security system. Light is bright and has options for steady or flashing. Very well made and fit my use case perfectly.

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.

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.

Since I did not get a clear answer from the seller, I opened the package and it was only then that I found a label on the light that actually states the black wire is to be connected to the neutral or common wire. Who in the H--- uses the word "naught"? All the other colored wires are connected with your power supply, usually black or red, wires. The light works great.

My family and I always forget to turn off the garage light. So I wired this to the garage light switch, and set it to flash mode. Works like a charm, no more leaving the garage light on for hours on end.

The buzzer is not 90DB at all, we can barely heard it if noise around the tower !The light is good but still very disappointed about the buzzer …

It is difficult to see the lamps in daylight. They are ok in the dark.

Bon rapport qualité prix

The use case is indicating the power in an outbuilding which I plan to convert to solar - so "High intensity LED signal light with low power consumption, can be viewed easily at a distance", as the product is described, sounded just right. Now, both "high intensity" and "low consumption" are without numbers a matter of opinion, so I was curious how the product will actually fare.Another thing I had noticed was the review that stated that there was no blinking functionality, while still giving it four stars. It was not a show stopper for me, but still a nice-to-have.So the product came in without any obviously accessible switches that could control blinking. I had a look at the video that is a part of the description and tried harder to open the light in the way shown in the video - and eventually managed to do it, and activate the blinking too. The unit - at least the one I got - was pretty hard to open, without being sure how to open it I was worried I might break it if I force it. Not significant enough to lower its rating.There were also no instructions; again, not an issue - the video shows everything you need to know. A no-nonsense product that is high on functionality and low on overhead.So we get to measuring the power consumption. Long story short, both lights (my unit has two, red and green) use no more than 0.7W together - low enough for me. Both lights left for twelve hours used only about 7Wh (or 0.007kWh, if you'd like). These numbers don't seem to add up - this is probably because both are at the lowest level of what the instrument could show and rounded differently (0.7W means anywhere between 0.65W and 0.74W, and 7Wh means anywhere between 7Wh an 7.99Wh) one way or the other, the actual consumption shouldn't be more than 0.66W or 0.33W per single light.One reason why I was interested in blinking was possibility that it might reduce the consumption somewhat - particularly if the duty cycle was short like you typically see on antenna towers (short flashes with long pauses in between). Unfortunately from that perspective, the blinking is fast paced with about the same length of the flash and the pause - and it actually slightly increased the consumption: about 8Wh were register over the 12 hour period, which puts the consumption between 0.34W and 0.375W. Nevertheless, blinking mode may still be worthwhile, as it is easier to spot the blinking light from the distance, particularly in bright sun.It is too early to talk about the reliability or the longevity of the product (it is in practical use only a couple of days now) - other tan that, it lives up to the promises in the description and is very good value for money. I like it and recommend it.

Gute Leuchte mit Summer.

Eenvoudig aan te sluiten, voldoende lichtopbrengst en netjes rondom verlicht.

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.
