What is a stack light?
Stack lights, also known as signal tower lights or andon lights, are columnar visual and audible indicators used in industrial environments to signal machine status to operators and technicians.
Where are these lights commonly used?
They are primarily used on equipment in industrial manufacturing and process control environments to identify errors or operational statuses as they happen.
What types of illumination sources are used?
Stack lights typically utilize high-visibility LED, incandescent, or xenon-type strobes as their primary light source.
How many color segments can a tower light have?
A standard stack light can have up to five different colored segments (typically red, yellow, green, blue, or clear white) which can be actuated independently.
What are the available flashing patterns?
The segments can be configured to be either off, steadily lit, or set to a strobe flashing pattern depending on the specific machine condition.
What materials are used for the construction?
Our signal lights are constructed with high-quality PC lenses and a durable ABS base, ensuring long-lasting performance in industrial settings.
