Columbia CRW4-LSCS – Frequently Asked Questions

1) Can the Columbia CRW 4-foot round wrap be dimmed, and what control does it need?
The CRW ships with a 0-10V dimmable driver that takes the fixture down to 10 percent output, so it needs a 0-10V control channel run to the fixture, not a standard line-voltage dimmer. If you wire it to a plain incandescent-style wall dimmer it will not dim correctly. On a retrofit where no low-voltage control wiring exists, plan on pulling the purple/gray pair or leaving it non-dimmed.
2) Will the Columbia CRW4-LSCS wrap fixture run on 277V, or do I need a separate 120V version?
One part number covers both. The CRW4-LSCS operates on universal 120-277V input, so the same fixture goes on a 120V branch circuit in a corridor or a 277V circuit in a commercial building with no different model to order. That is the reason to standardize on it across a mixed-voltage facility.
3) How do I change the brightness and color temperature on this LED wrap after it's installed?
There is a switch on the side of the driver that sets both the lumen output and the color temperature in the field. No tools beyond opening the fixture and no separate SKUs for each output. From the factory the fixture arrives set to 40W and 3500K, so if that is what the job calls for you can hang it and move on. For a property manager stocking one fixture for several buildings, that switch is the whole point: one part number covers multiple lighting specs.
4) Can the Columbia round wrap go in a parking garage, covered walkway, or unheated stairwell?
It is damp location rated, so covered exterior areas, walkways, and doorways where it sees humidity and condensation but no direct water are fine. It is not rated for wet location, so skip it anywhere it takes direct rain or hose-down washdown. Typical listed applications are building facades, doorways, and walkways.
5) What does the wiring and mounting look like on the Columbia CRW wrap, and does it come assembled?
It arrives fully assembled, so it goes straight to the ceiling or wall without building it out on the floor. Electrical access is from the middle of the exterior of the fixture, which means your outlet box or whip needs to land near the center of the fixture run rather than at an end. Worth checking against existing box locations before you pull the old fixtures down. Follow the supplied installation instructions for the mounting details.
6) Is this LED wrap UL listed for commercial use?
The CRW is built to UL 1598 standards and carries the cULus label, which covers both US and Canadian installations. It also complies with LM79, LM80, and TM21, the test standards a spec writer or energy consultant will ask for when they want documented lumen output and lumen maintenance rather than a manufacturer claim.
7) How long will these LED wraps last before I'm back on a ladder?
The LEDs are rated 54,000 hours at L70, meaning 70 percent of initial output remaining at that point. On a corridor running 24/7 that is over six years; on a 12-hour school or office schedule it is well past a decade. There is no lamp or ballast to replace in the interim, which is the maintenance argument for pulling out fluorescent wraps.
8) Will this wrap fixture show color accurately enough for a retail or healthcare space?
CRI is 80+, which is the standard commercial benchmark and fine for corridors, offices, stairwells, storage, and general retail. If the spec on your drawing calls for 90 CRI for color-critical retail display, exam rooms, or art, this fixture does not meet it and you want a high-CRI luminaire instead. The frosted acrylic lens diffuses the source, so you get a soft even wash rather than visible LED pixels.
9) Can I add an occupancy sensor or photocell to the Columbia CRW wrap?
Occupancy and photocell sensors are available as options on the CRW. That matters for code compliance: many commercial energy codes require automatic shutoff in storage rooms, restrooms, and corridors, and integral occupancy sensing satisfies it without a separate wall sensor and extra wiring. Sensor options are specified when the fixture is ordered, not added later in the field.
10) How efficient is this fixture compared to the fluorescent wrap I'm replacing?
Efficacy runs up to 150 lumens per watt. A two-lamp T8 fluorescent wrap of the same 4-foot length typically lands in the 80 to 90 lumens per watt range at the fixture, so you are cutting connected load roughly in half for the same light on the floor. The steel housing and end caps match the general look of a fluorescent wrap, so a phased building-wide swap does not leave obviously mismatched ceilings.
11) Where can I get the full spec sheet for the Columbia CRW round wrap for a submittal?
Columbia publishes a spec sheet for the CRW that covers the photometrics, switch settings, and dimensional data you need for a submittal package. It is available at zensupply.com/content/pdf/columbia/COL_CRW_spec.pdf. Submit it alongside the DLC qualification record if the job carries a rebate.
