What are the limits in run lengths?

The line can be continuous – it has an unlimited effective length. Standard run length lenses are singular up to 26ft long (They roll up in a 4ft diameter so they can fit in an elevator). Longer lenses lengths are available.

What corners are possible and how to specify?

Lines can turn or transition. Catalog numbering includes the direction and degree:

  • Specify right (RT) or left (LT) with the required degree. Example – RT90 is a right turn 90 degree corner
  • Specify (ICxx) for an inside corner, e.g., wall to ceiling
  • Specify (OCxx) for an outside corner

Why doesn’t the corner ship as a separate component?

Think of our products as illuminated crown molding. The RTxx, LTxx, ICxx or Ocxx tells us how to prepare the corners:

  • The RTxx and LTxx describe how we detail the ends of two housings to turn right or left
  • The ICxx corner denotes housings that overlap in the corner; allowing for minor adjustment when the as-built corner is not exactly square. The LED panels and lenses also overlap, so the contractor is not required to cut each lens perfectly

Can corners turn any angle?

Theoretically yes, However as the angles get more extreme, especially with a right or left turn, the unsupported sides of the lenses may allow for a slight light leak where they meet.

What if the inside corner is not exactly 90 degrees?

Since construction is seldom always perfect, the ICxx allows a tolerance of +/- 10 degrees at the hinge point in lieu of having a rigid joiner that can make for a less than perfect transition.

Are the LED modules mitered or just the lenses?

Both are mitered. This also allows for angled ends, so the light truly dies into the wall at the angle desired.

What are the various end conditions?

All lines have to stop. While the lens might look the same on the surface, below the drywall they are constructed differently.

M – Miter Mud in – for use when the end is in the middle of a wall. It allows full support of plaster coat on the full perimeter of the fixture.
S – Straight cut – for use when the fixture ends at an object- such as adjacent wall, or baseboard, Use it when the flange of the M corner will not fit the remaining space.
ST – Straight Translucent – Allows light to bleed out end at expansion joint or with regressed baseboard.
A – Angle cut – for a different look in the creation of designs. It can be specified with an angle from 45 degree to 90 degree, (of course 90 degree is the same look as the basic S end condition.) Useful when the line of light runs into a sloped object, like the baseboard of a stair or ramp.
AP – Arrow Point – adds directional feeling to the end; angles are 45 degrees with a slight 1/8 radius at the tip of the arrowhead.
RHC – Radius Half Circle – produces a semi circular end for the line.
R4C– Radius 1/2 inch corners – produces a soft radius corner – measured in eights of an inch so 4C, equates to 4/8 or 1/2 inch corners.

All of these ends also have a different measure point used when calculating the total length of the fixture, which will be reflected in the catalog number.

Can different housing types be used in the same pattern?

Absolutely! Send us your design requirements and we will advise the layout and products needed.

Catalog numbers list both English and SI (metric) units, do you have a preference for units?

No, as a famous fast food chain is found of saying- Have it your way. We allow the specifier to work in the units they are comfortable with, and specify the unit designator in the catalog number in the end position; we speak both dimensional languages well. We can manufacture to the closet 1/16-inch or 1mm. Items will not be quoted or constructed without a unit designator.

How do I specify a length if it is fitting between two objects that are not constructed?

Specify split shipment of housing (H and L option) and LED modules and the field cutting (FC) option. This allows for field cutting on a chop saw with a blade for non-ferrous material on site for a precise architectural fit. Detailed instructions make this easy for a contractor. Once installed, Contactor then provides the installed length(s) so the LED modules can be made to fit. Shop drawings show location of cutting panel, it maybe at the end of a run or in the middle of the run depending of the specified ends.

This eliminates what the other manufacturers make you go through with telescoping ends, contractors trying to cut housings with tin snips, complex and confusing length charts, or visually dark ends due to different lamps types.

Can larger variations of the product be produced?

Consult factory for available widths. We can produce custom widths up to 6 inches (150mm), with a minimum 1000ft order. Lead times may be up to 10 to 12 weeks for non-standard sizes.

Can the product provide theatrical color light?

Absolutely. Dado can provide static colors, RGB, RGB+W, or any Rosco gel.

Can the product dim?

Yes! Power supplies are available for dimming via 0-10V, two-wire phase forward, DMX or DALi controllers.

Can text and logos be printed on the lens?

Yes! Various graphics from room numbers to logos or serene sky scenes can be printed on the lens.

Why use a remote driver?

LEDs produce waste heat, as do the drivers. We remove the driver from the LED housing, separating the electronics of the driver from the increased ambient to produce lower operating temperatures on the critical components. The old rule of thumb is for every 10-degree decrease in temperature, there is a 10-year increase in component life.

Why are Dado drivers limited to 100W?

Class 2 circuits as defined by the NEC are power limited to 100VA. A class 2, 24V DC circuit can deliver up to 4.1 amps of current and provide protection from electrical shock. These are defined as inherently safe. We separate the Power supply from the housing to gain maximum advantage of this system, similar to a remote low voltage halogen system, which most specifers and contractors have had experience with.

Where can the remote power supply be mounted?

The remote power supply can be surface mounted, recessed mounted and even mounted above an accessible ceiling. Remote power supply can house up to (3) 100W non-dimming drivers or (2) 100W 0-10V dimming drivers. Most units are even IC rated.

What is the maximum remote mounting distance for the remote power supply?

Fixtures ship standard with 15ft of 14gauge CL2P wire. Up to 50ft of #12 AWG wire can be added with ELV & N100, or up to 20′ with D010 power supplies. Consult factory of longer remote distances are needed.

What is CL2P wiring?

CL2P stands for Class 2 wiring, plenum rated. It is the most stringent option available in class 2 cables, even above the R, riser, rating. This means you can run the class two wires from the fixture to the remote power supply above ceilings, in plenums, or walls to give great flexibility in placement of the remote driver. Fixtures ship with 15feet of this cable attached to the housing.

Does the housing ship with wires installed?

Yes! Fixtures ship standard with 15ft of 14gauge CL2P wire factory installed. For cut-in installations, simply leave a pull string to pull the feed cable through to the power supply.

What about Chicago Plenum installations?

We offer a Chicago Plenum, #CP, option for most products. In lieu of a feed cable, a Chicago Plenum rated junction box is attached to the housing to allow 1/2” conduit to be attached. On SimpleLine housings, the j-box can be re-positioned 6” in case a structural member is in the way.

Whose LED is in the module?

Nichea’s 757 LED chip is installed onto our board design at a factory in Minnesota.

How do you consider color shift in the design?

While we use LED’s binned to 2 MacAdam ellipses or less like many premier manufacturers, most linear products place their LEDs facing directly out to the lens and use a deep optical cavity. Organizing the LEDs this way may create concerns since as an LED ages, the potential for color shift occurs, which could produce hints of green or pink in your field of white. If a single LED shifts in these direct view unit, its tell tale color is projected directly on the lens to be seen by all. In lieu of this we organize our LEDs differently. We use the PMMA wave guide as a way to provide a final mixing of a large group of LEDs so if a single LED shifts, its light is remixed and blended with its neighbors to avoid hints of color shift.

Are there socket shadows where the LED modules meet?

The wave-guide panel allows the light to be mixed and is visually undetectable over a 1-1/2” length.

Can SimpleLine LED mount in exterior surfaces?

We can mount in damp listed applications e.g. under canopies. No direct water spray areas. 

Are there emergency options?

Any 24V DC supply may be used such as a battery backup system. For areas where you only want small portion of the lens illuminated in EM mode, utilize the #2C denotation and consult factory for the proper wiring method and order logic.

Do the mounting surfaces need to be wiped with alcohol, as other tape light systems require?

No. Dado LED modules are pre-assembled at the factory. They need only be installed into the housing with the supplied mounting screws.

Can the housings be field cut?

Housings ordered with the field cutting (FC) option can be cut with a blade for non-ferrous material on site. If housings that were not ordered with the FC option needed to be modified, please contact the factory ASAP for detailed instructions where to cut and whether new LED panels will be required. The LED panels cannot be cut in the fold.

How do we change out the LED Module?

All LED panels carry a replacement catalog number. The DC connector allows for quick replacement of a module. Since it is Class 2 voltage, anyone can do the maintenance. In the future, the owner may wish to upgrade to the current state of the art LED chip. If the upgrade is selected, drivers may have to be switched. The housing has been designed so to provide mass and heat sinking to allow the next generation of LEDs and OLEDs. We have provided wiring and clearance chambers on each side of the fixture to keep the future open for our customers and us.

How is lens and module removed for field replacement?

To remove the lens, insert a flat blade screwdriver, plastic card or putty knife in space along the side near the end between housing and lens to bow the lens and allow it to be grabbed. To remove the LED modules push slightly to one side and then pull and rotate long edge out of the housing.

How to install in a fire-rated ceiling or wall?

In fire-rated drywall construction, instead of building a “tent” around the fixture, simply add an additional layer to be flush with the SimpleLine fixture.

Where is the product made?

Our products are proudly made in the U.S.A outside of Chicago IL. All components except the LED chip and the acrylic light guide panel are made in the U.S.A. as well (there are no North American sources for these currently).

How fast can you ship?

Typical lead-time for straight or common patterns is 6 weeks from approved shop drawing and receipt of payment. Simple layouts with housing first option (H), can ship even faster, please Consult factory. More involved patterns will take longer.

How does field cutting work?

Housing can be ordered with the field cut (FC) designation; allowing the housing to be prepped for cutting in the field to the exact dimensions desired. The LED panels and lens are then ordered to the final installed length.

Can the housings be shipped in advance?

Yes! Order with the “H” option. When ready for the LED and Lens, the same catalog number with the “L” option ships within two weeks.

I have a pattern from my project. Can the factory create a bill of materials from a drawing?

Yes. We can process any DWG or DXF formatted drawing. Send plans and elevations. We can generate the Catalog number and the required drivers.
