The TETRUS Story

Energy saving, cost-efficient LED lighting solutions for commercial and industrial facilities and outdoor areas

The TETRUS Story

Headquartered in Milford, Delaware, Tetrus is a top-to-bottom LED lighting provider with unmatched expertise in the development, manufacturing, and application of LED lighting solutions for commercial and industrial facilities and outdoor areas.

LED technology is changing the face of commercial and industrial outdoor lighting allowing businesses to reach higher levels of energy savings and economic growth. 

Tetrus remains at the forefront of the latest developments in the LED technology constantly improving the application of light to effect long-term benefits to our customers and their businesses.

The Beginning: American Sign & Lighting to TETRUS

Tetrus started as American Sign & Lighting more than 30 years ago. An established sign and lighting contractor with a reputation for excellence, American Sign & Lighting dedicates exclusively to servicing commercial and industrial outdoor lighting systems.

Operating through a comprehensive network of certified electricians, American Sign & Lighting has serviced and literally touched more exterior lighting than any other company on the East Coast because we have specifically focused on commercial and industrial lighting, which includes parking lot lights, wall packs, canopy lights, high bay lights, high mass lights, street lights, etc. 

We do not do banners, outlets, residential lightbulbs, building wiring, or interior lighting. Our niche is outdoor and industrial-grade lighting. After three decades in the industry, we’ve grown to boast a diverse customer base that includes shopping centers, car dealership, gas stations, banks, fast-food restaurants, manufacturing facilities, hospitals, hotels, universities, municipalities, and more.

Our portfolio includes names such as Taco Bell, McDonald’s, Sherwin Williams, Wendy’s or Blockbuster, all long-term clients because they know we really care about their business.

We service from bucket trucks fully-stocked with everything you could possibly need, which literally eliminates return trips and dramatically reduces overall costs. As a result, our men have more trade-specific and product-specific experience in the outdoor and industrial lighting market segment than any other lighting company on the East Coast.

The Battle with the EELs

Despite propaganda, existing LED fixtures for commercial and industrial facilities must be replaced every 3-5 years because they cannot be serviced; they are designed in such a way that electricians cannot get inside the fixture to replace a defective part.

Or, if they can get inside the fixture, the parts are no longer available with the manufacturer and it costs too much to find compatible parts from other suppliers.

Plus, warranty departments make it so difficult and complicated to validate your warranty that clients will have already paid for a new fixture by the time the manufacturer makes a decision about the warranty.

Since the whole fixtures have to be replaced every 3-5 years, all savings made possible via LED technology amounts to nothing. We decided to add design and manufacturing to our business because we grew tired of servicing LED fixtures that have never been intended to be serviced in the first place.

Today, Tetrus designs, manufactures, installs, and services LED lighting for commercial and industrial facilities with a focus on exterior LED lighting. We have focused on designing the perfect LED fixture that was engineered to last, unlike competing LED fixtures that are engineered-end-of life (EEL).

The TETRUS Difference

The Tetrus LED fixture brings a number of innovative changes designed to allow our clients to enjoy the energy savings made possible by the LED technology well beyond the lifespan of LED light or 3-5 years. The only way to justify the larger initial cost of LEDs is via a serviceable fixture that comes with long-term energy savings and low-maintenance costs. Here is the Tetrus difference:

Standardized Serviceable Design

The design of the Tetrus LED fixture permits quick and easy access inside to evaluate which parts is malfunctioning and quickly replace it, be it LED driver, LED component, or wiring harness. All components are standard for all Tetrus fixtures, irrespective of wattage, which means our trucks can roll with stock and fix whatever fixtures fit your facility.


Modular Design

The LED component is modular meaning that it consists of several independent 50W LED modules. As such, a 100W LED fixture consists of two 50W LED modules, a 150W LED fixture consists of three 50W LED modules, and so on. As each 50W LED module is independent from the remaining modules, the Tetrus fixture will continue to glow even when one module goes out. The module is standard, so you can even keep it in stock.

Industrial-grade Durability

Tetrus focuses exclusively on commercial and industrial lighting and, mostly, on exterior lighting, which led us to develop sledgehammer-tough and ocean-proof fixtures that can shine despite harsh environmental and industrial conditions, as well as in spite of vandals and criminals that hate well-lit areas.

The Best LED Light

While we have improved our design to ensure serviceability, we have made sure to offer the highest efficacy in the LED industry so that our clients enjoy even higher energy savings. Enhanced by multi-patented light distribution, our LED light allows customers to pay only for the light they need at any given time.

The TETRUS Light-time Pledge

Tetrus brings into play the ideal outdoor LED lighting fixture that has a perfect set of characteristics: standardization + modular design + serviceability + durability + highest efficacy + better quality of light.

The Tetrus fixture saves you money because you can fix it and never have to replace it, because its modular design affords the lowest possible maintenance costs, because its durability keeps it shining in the most difficult of circumstances, and because our fixture has the highest lumen output as well as the best light distribution.

Essentially, it all translates into more and better light for less wattage and, subsequently, more energy savings for you. While we have designed and improved each feature of our LED lighting fixtures to become a solution to your pains, we also believe in offering the best customer experience in the LED industry via:
