Our facility in Crystal Lake, Illinois

At Big Beam, we have dedicated ourselves to providing top quality products while offering the highest possible level of service to our customers.

A Total Quality Concept permeates everything we do as a manufacturer. Big Beam manufactures products designed for use in emergencies…
Relying on anything less than the best is unconscionable.

While competitive pressures may dictate that cheaper, less capable units are more saleable, we will not lower our standards. This was true in 1938, when we pioneered a new venture in a fledgling industry, and remains so today.

In our business, quality products and performance are a public trust, and we will not violate that trust.

We work hard to EARN your business. We hope this web site services you well whether specifying or considering a purchase of emergency lighting or other products. Please send us your feedback.
