Yes. A MLV dimmer is typically used to dim our magnetic transformer. Please note that we do not provide MLV dimmers.
Yes. Our Aisle and Step Lighting are made of rubberized PVC which can easily take gentle curves.
We have found that Aisle lighting can bend at about 10°/ft and Step Lighting at about 5°/ft. These values are estimates and vary between profile shapes; this should not be taken as absolute data. Contact a Primus technical specialist for more information.
Step & Aisle Lighting is mounted using Loctite PL 3x Premium or similar adhesive and strapped/sandbagged in place while curing takes place.
Ensuring your order gets to you on time and without any damages is one of our top priorities. We understand that some carriers may be indifferent about getting your order to you without any damages. We have found and tested that using double wall boxes, biodegradable foam, flow pack, and bubble pack is the best way to keeping your product safe, protected, and cost effective.
12 ft boxes are typically the longest we ship. We can do longer boxes; however, this will result with higher risk of damaging fixtures and costly freight.
We have conducted extreme weather testing at -40 Celsius for 100 hours. Impact and Pull testing were conducted throughout the testing and the system was still fully operational by the end of the test.
It is possible; however, we do not recommend purchasing Decostring without our lamps because we can no longer take responsibility of the ETL listing and warranty may likely be voided.
If you would still like to purchase the Decostring system without our lamps, please ensure that the lamp used is a wet-rated lamps and you will need to sign a letter releasing Primus Lighting, Inc. of any liability.

You can add certain shades after purchasing your system, but only the following options:
These can be ordered separately if needed. However, placing one order for everything at once is recommended to avoid double freight charges.
Please note that some shades MUST be ordered with the Decostring system, as they can only be installed at the factory:
Title 24 is California’s building energy efficiency standard, which sets performance requirements for lighting fixtures in nonresidential buildings to reduce energy consumption. To comply, most LED fixtures must achieve a minimum efficacy of approximately 80 to 100 lumens per watt, depending on the fixture type and application. Additional requirements include the use of high-efficiency drivers, low standby power consumption, and compatibility with lighting controls such as dimmers and occupancy sensors.
LM79 is a standardized testing protocol developed by the Illuminating Engineering Society (IES) for LED luminaires. It provides verified data on a fixture’s electrical and photometric performance, including wattage, total lumen output, and luminous efficacy (lumens per watt). LM79 test results are critical for demonstrating compliance with Title 24 and other energy efficiency standards.
Yes, our fixtures are designed to comply with Title 24 requirements for nonresidential applications. They achieve the required 80-100 lumens per watt efficiency, integrate with necessary lighting controls, and have been tested under LM79 standards to verify compliance. Certification documents and test reports are available upon request.
TM-21 is a testing methodology developed by the Illuminating Engineering Society (IES) to predict the long-term lumen maintenance of LED light sources. It helps estimate how long an LED will retain a certain percentage of its initial brightness over time, using data from LM-80 testing.
TM-21 uses LED performance data collected through LM-80 testing, which measures lumen output over at least 6,000 hours. This data is then extrapolated using a standardized formula to estimate how long an LED will take to degrade to:
These ratings indicate the expected useful lifespan of an LED before noticeable light loss occurs.
TM-21 projections provide a standardized and reliable way to predict LED longevity, which is crucial for:
Without TM-21 data, it would be difficult to determine how well an LED fixture will maintain its brightness over time.
Approximate hours of life for Step & Aisle Lighting is 50,000 hours.
Yes, but only our standard lamps. Premium lamps will cost more. Refer to the Decostring cutsheet or consult factory for more information.
83 CRI is standard with most of our lamps; however, there are few options up to 90 CRI that are more costly.
Established by the federal government, the Buy America Act promotes the use of USA products for government jobs with the aim of supporting the local economy. Under the BAA, there is a two-part test to determine whether a product is domestic:
Some products may meet BAA compliance depending on the project and sourcing requirements. Please contact us with project specifics to confirm compliance. We are proud to to say we are made in America however BAA requires additional specific percentage compliance. Contact factory for specific BAA compliance.
Yes. While both step and aisle fixtures can be field cut for minor length adjustments, typically at the beginning or end only, aisle lighting is significantly easier to modify in the field. We strongly recommend providing exact lengths at the time of order to minimize the risk of field errors, such as cutting the fixture or wiring too short.
Yes, and even better, most of our lamps are Dim to Off. Please note that we do not provide dimmers for our lamps. We are compatible with most trailing edge dimmer. Click here for more info.
Our Decostring is ETL listed for permanent wet installations. Decostring has also been installed in various regions with harsher weather, such as wind, heavy rain, snow, and extreme heat. We are comfortable to say that our Decostring can handle weather elements well. For more information, contact a Primus technical specialist.
Decostring can be cut in the field for minor adjustments in overall length, typically at the beginning or end of a run. Each Decostring includes an additional 4 feet of power lead to provide some on-site flexibility and trimming.
However, significant modifications—such as splitting a 100’ run into two 50’ runs—should not be done in the field. The best solution is to specify the required run lengths in advance so they can be properly terminated at the factory. If adjustments must be made on-site, the only way to maintain product integrity and preserve the warranty is by using a wet-rated junction box, with all connections made inside the enclosure by a licensed professional.
Field-cutting and connecting without proper enclosure and termination can compromise the product’s performance and will void the warranty.
We do not supply dimmers with our Decostring system.
We recommend single runs for zig-zag or multi-attachment point patterns. They allow for easier installation, adjustment, and removal for service or repair. However, the choice is ultimately up to the customer.
Single Runs
Pros:
Easier installation
Easier adjustments
Easier removal for service/repair
Cons:
Slightly more costly
Continuous Runs
Pros:
More cost-effective
Cons:
Difficult to adjust
Not ideal for zig-zag patterns
Entire system must be removed for service or repair

Technically, yes. Decostring can operate on 12V or 24V by using compatible lamps and a transformer to step down the voltage from 120V.
However, Primus does not offer or recommend these configurations for the following reasons:
Important: Even if the customer provides their own lamps and transformer, the system would not be covered under our current ETL listing, potentially creating a certification issue.
Yes, except for the Hat shade (DSH), Radial Wave shade (DSRW), and Reflector Guard shade (DSRG). These shades must be preinstalled in the factory.

Yes. Our standard is 3/32” stainless steel aircraft cable, but we can also use 1/8” or 3/16” cables if needed. Please consult a Primus technical specialist to determine if a larger cable is required for your application.
Not at all. Raw brass naturally has imperfections and will develop a patina—often turning green over time—which enhances its appearance and character.
We include an extra 4 feet of aircraft cable on both ends of each Decostring run to allow for on site adjustments. Power cable includes an additional 4 feet on one end only. As a general guideline, adjusting one end by approximately 3 inches will create about 12 inches of droop.

No. Because installation conditions can vary (e.g., ambient temperature, ventilation, or enclosure type), the transformers supplied do not come derated.
Yes, we can add a Bi-level motion sensor that is pre-installed in the factory but needs to be programmed in the field, programming instructions are included. Sensor is mounted under the lens; it adds 3″ to the length of the fixture. Specify or consult factory for other type of sensors requirements.
Primus Lighting will handle shipments using our preferred carrier and customs broker. This allows us to provide a freight estimate and an approximate duty estimate. Please note, the duty estimate is only an approximation; actual duties may vary based on classification, inspection, or other CBSA factors at the time of entry.
Yes, they may use their own broker. However, in this case, they must also use their own carrier. We cannot coordinate between our carrier and a third-party broker due to past issues.
Primus Lighting provides a complimentary String Lighting Horizontal Load Calculator to help estimate the approximate horizontal (lateral) load applied to supporting poles based on span length, suspended weight, and cable sag.
This calculator is intended as a reference tool for engineers, contractors, designers, and installers during the early stages of project planning. It provides an approximation of dead-load forces and includes supporting reference information regarding the Primus string lighting suspension system.
The calculator includes:
Download the latest version of the calculator below:
Disclaimer: This calculator provides an approximate dead-load calculation only. It does not account for wind loads, seismic forces, installation pre-tension, dynamic loading, uneven attachment heights, hardware reduction factors, building code requirements, pole design, anchorage design, or foundation design. Final pole selection and structural design shall be performed by the project structural engineer or other qualified design professional.
No. Primus Lighting manufactures the string lighting system but does not provide structural engineering or recommend pole sizes. We provide product specifications and reference load information to assist the project’s structural engineer, who is responsible for verifying pole size, foundation design, anchorage, and compliance with applicable building codes and site-specific loading conditions.
Turtle friendly lighting is designed to reduce the impact of artificial light on sea turtles during nesting and hatching seasons. Sea turtles are highly sensitive to short wavelengths of visible light, generally between 400 and 560 nanometers (nm), which can disrupt natural behaviors and cause disorientation.
These systems use long wavelength amber light (typically 580–620 nm), minimize blue and green emissions, and direct light downward to reduce impacts on nesting areas. Compliance depends on the complete lighting system, including fixture design, optics, shielding, and installation, and may vary by local regulations.
Primus Lighting does not currently offer turtle friendly lamps. Although our LED lamps do not emit ultraviolet (UV) light, turtle friendly lighting requires specific wavelength and design criteria that our current products do not meet.
For projects requiring turtle friendly lighting, we recommend reviewing project specifications and local regulations before selecting a solution.
