In conjunction with SCADA supervisory control systems and user interface/HMIs: SCADA/HMIs provide more
specific machine/process status data; stack lights complement them by providing visual/audible feedback away
from the machine operator console.
Assembly station workcells
Maintenance call stations
CNC machining equipment and process monitoring and feedback
Broadcast studios (commonly used in broadcast radio studios) to display status of things such as a studio on air,
live microphones, phone calls and even as a doorbell in an environment where silent indication is critical.

Dispatch centers where the dispatcher frequently uses a headset making it difficult to tell when the dispatcher is
on the phone or radio. The light will light one color when the radio is keyed and another when on the phone.
Driving of Led Stacks
A LED driver is a power regulator . Technically it is a circuit which is responsible for regulating and supplying the
ideal current to the LED. The LED driver provides power and regulates the variable needs of LEDs by providing
constant amount of power as the properties of it change with temperature.
An LED driver is a device that regulates and supplies the optimal current and voltage to an LED light. An LED
light is a type of lighting that uses light-emitting diodes (LEDs) as the source of light. LEDs are more efficient
and durable than traditional bulbs, but they also have different power requirements. LEDs need a constant and
precise amount of power to work effectively, as their properties change with temperature and age. An LED driver
provides this power by converting the high voltage alternating current (AC) from the building to the low voltage
direct current (DC) that the LED needs.
An LED driver is essential for the performance and longevity of an LED light. Without a good LED driver, an LED
light may not work properly, or it may burn out quickly. Most LED failures are not caused by the LED itself, but by
the driver. The driver is a complex circuit board that has to withstand constant power conversion and regulation.
The driver may fail due to overheating, short-circuiting, or poor quality components.

LED Lights can last decades, but only if they have a good LED driver. See our How LEDs work section for more
about general LEDs.
In an LED Light the driver does all the heavy lifting. Whether its an LED Corn light bulb or an LED fixture it has a
driver inside. That driver takes input from the building in alternating current or ac and converts it to direct current
or dc. In your home that means from 120vac down to 36vdc or 48vdc. It works as a giant transformer. Doing that
constantly requires a very high end product. Most of the issues we see with LED failures are from the driver.
An LED driver can be found inside any LED light, whether it is an LED corn light bulb or an LED fixture. The
driver can vary in size, shape, and design depending on the type and application of the LED light. For example,
an LED high bay light may need a more powerful and robust driver than an LED path light. The driver can also
have different features, such as dimmers, timers, motion sensors, battery backups, wattage selection or remote
controls, that can enhance the functionality and convenience of the LED light.
