Decostring FAQ's

Decostring System includes:

  • Sockets
  • Wire
  • Aircraft Cable (Support Cable)
  • Standard Lamps

Not Included:

  • Termination Kits (Standard Termination Kit, Turnbuckle Termination Kit,
    Lightweight Termination Kit)
  • Shades
  • Premium Lamps
  • Plugs
  • Lamp Silicon Coating
  • Suspension Kits

Yes, but only our standard lamps. Premium lamps will cost more. Refer to the Decostring cutsheet or consult factory for more information.

85 CRI is standard with most of our lamps; however, there are few options up to 90 CRI that are more costly.

Yes, and even better, most of our lamps are Dim to Off. Please note that we do not provided dimmers for our lamps. We are compatible with most trailing edge dimmer. Click here for a detailed list of dimmers.

There are four factors that influence the total length of a run: length of power cord, electrical load, physical/mechanical practicality implications, and shipping.

The longest run length would be 490ft based on a 500 ft maximum length because our power cable comes in 500’ spools.

Each run is technically rated for a full 20A (1920w derated) 120v circuit however this is never exceeded now with LED lamps. Therefore, electrical load is not going to be an issue because if you were to hypothetically load a single circuit with a single run of our Decostring, it could be over a mile (5280 ft) in length to max out 1920 watts.

If the goal is to determine the maximum single run length with only two attachment points for installation, then it will be a question of physical and mechanical implications. Our Lightweight termination kit has a working load of about 30 lbs. Our Standard and Turnbuckle termination kits have a working load of about 175 lbs. If the Decostring system weighs 5oz/ft with 24” O/C, then the Lightweight termination kit can theoretically handle up to 96 ft. The Standard and Turnbuckle termination kits can handle up to 560 ft.

We can package well above 500 ft of Decostring in a single box. However, freight will likely increase because a larger box will be needed.

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.

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 to make some minor adjustments in length.

Significant changes in length are also possible but we do not recommend doing this because you risk damaging the product and risk the project by cutting a run length too short.

We do not supply dimmers with our Decostring system.

We recommend doing single runs for zig zag patterns or any type of patterns where there are multiple attachment points because this allows for easier installation, adjustments, and removal if necessary. However, this decision is at the discretion of the customer.

When caught between two whole numbers, such as 10’ and 11’ and unsure if you should round up or down,we have found this to be the best results:

  • Round Down: 9”, 12”, 18” and 24” O/C spacing
  • Round Up: 36” and 48” O/C spacing

Here are a few examples for clarification:

  • 100’ 6” Run @ 9” O/C Spacing = Round Down
  • 58’ 4” Run @ 36” O/C Spacing = Round Up
  • 20’ 8” Run @ 18” O/C Spacing = Round Down

Decostring can work with a 12V system, but we do not recommend because you must use transformers which can make the project costly. This also makes planning and manufacturing more difficult because you are drastically limited with run lengths when you use a 12V system.

Yes, except for the Hat shade (DSH), Radial Wave shade (DSRW), and Reflector Guard shade (DSRG). These shades must be preinstalled in the factory.

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.

The most common bare lamp spacing is 24” o/c. Estimate the complete dead load weight at 5oz / ft or about 15LBS for a 50’ run. For a 7” cone shade at 48” o/c the estimate only changes to about 7oz / ft. Largershades and alternate spacing changes these values a bit. System maximum working load is 175LBS which includes lighting system and termination hardware kits.

Our standard is 3/32” Stainless steel aircraft cable, but if needed, we can also use 3/16” or 1/8” cable. Consult a Primus technical specialist to determine if a largercable is needed.

Raw brass comes with imperfections as it is and will gradually turn green and improve appearance over time.

We provide an additional 4’ of wire and cable to both ends of a Decostring run. This allows you to adjust the system as needed. Please note that for about every 3 inches you adjust on one side of a run, you get about 12” of droop.

Established by the federal government, the Buy American 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:

  1. it must be “manufactured” in the United States; and
  2. the cost of domestic components must exceed a certain percentage of the cost of all the components.

Yes! All of our fixtures comply with the Buy American Act (BAA) standards.

Step & Aisle Lighting

Yes. A MLV dimmer is typically used to dim our magnetic transformer. Please note that we do not provide MLV dimmers.

Approximate hours of life for Step & Aisle Lighting is 50,000 hours.

Yes. Although both are field cuttable, Aisle Lighting is much easier for field cutting. We recommend that exact lengths are provided when submitting order to reduce the risk of field error, such as cutting lighting and wiring too short.

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.
