Columbia LXEM4-40HL-RFA-EDU – Frequently Asked Questions

1) Can the Columbia LXEM enclosed LED fixture be used in a wash-down food processing area?
Yes. The LXEM is UL Sanitation certified to NSF standards, which is what a food plant or commercial kitchen inspector looks for, and the housing is sealed with pour-in-place non-porous gasketing so water and cleaning solution do not get into the gear cavity. It also carries a Wet Location rating. Ingress protection is IP65 and IP67 standard, with IP66 on select models.
2) Will the Columbia LXEM 4 foot fixture work on 277 volt building power, or do I need a separate 120V version?
One fixture covers both. The LXEM runs on 120-277V, so the same part number goes on a 120V circuit in a utility room and a 277V circuit in a garage without ordering a different voltage. That is what lets a facility standardize on a single stocked item across mixed panels.
3) Does the Columbia LXEM dim, and will it work with a 0-10V control system?
Yes, 0-10V continuous dimming is available on the LXEM. Columbia also offers the fixture with a fixed output driver (straight on/off) or a step dimming driver that runs high/low/off, so if you are only pairing it with an occupancy sensor for a stairwell you can specify step dimming instead of a full 0-10V control run. The driver type is an ordering decision, so specify it up front.
4) Can the Columbia LXEM be used on an emergency circuit for egress lighting?
Yes, when it is equipped with a battery pack or the DTS Dimming Bypass Module, the LXEM is CSA certified to UL 924 standards. The DTS supports emergency circuit loads including sensors and wireless systems, which matters when the fixture is on a controlled circuit and you need it to go to full output when normal power drops. Both are ordering options, so they have to be specified with the fixture.
5) How do I mount the Columbia LXEM in a parking garage with an open deck above?
Three mounting methods are supported: surface, suspended, or chain mount. In a garage or open utility space where the structure is above the desired lighting plane, chain or suspended mounting drops the fixture to height; where you have a flat soffit or canopy deck, surface mounting sits it tight to the substrate. Parking garages and canopies are among the applications this fixture is built for.
6) Is a fiberglass enclosed fixture like the Columbia LXEM better than a steel wraparound for a parking garage?
For a garage, canopy, or wash-down area, the enclosed and gasketed type is the right call and a wraparound is not. The LXEM housing is formed from UL 5VA fiberglass with an F1 weatherability rating, so it is suitable for indoor or outdoor use with UV exposure, and it does not corrode the way painted steel does in a salt and moisture environment. An open wraparound leaves the LED board and driver exposed to dust, moisture and hose-down. Where you have a clean conditioned interior with no washdown, a wraparound is the simpler fixture.
7) How well does the Columbia LXEM hold up to vandalism or ball strikes?
The standard lens is a lineal ribbed frosted acrylic made from impact-modified material equivalent to 100% DR acrylic, with the modification adding flexibility to reduce impact breakage compared to standard acrylic. If the location is genuinely abuse-prone, specify the optional ribbed polycarbonate lens instead. A deep acrylic lens is also offered, and all lens options come in clear or frosted. Frosted diffuses the LED source; clear puts more light straight down and lets the diodes show.
8) Can the latches on the Columbia LXEM be made tamper-resistant for a public area?
The latches are tamper-resistance ready, but the tamper-resistant screws are supplied by others, so budget for those separately on public-access installs. Latches are standard polyacetal (POM) with stainless steel available as an option, which is the one to specify for wash-down or corrosive areas. The 4 foot fixture carries 8 latches (the 2 foot has 6, the 8 foot has 14).
9) Does the Columbia LXEM meet Buy American requirements on a federal project?
The LXEM qualifies as designated country construction material under FAR 52.225-11, Buy American - Construction Materials under Trade Agreements, effective 06/01/2020. That is the classification a government or institutional buyer needs for a trade-agreement covered federal job. The fixture is also built to UL 1598 and UL 2108 standards and labeled cCSAus, so it clears both US and Canadian jobs.
10) How long will the LEDs in the Columbia LXEM last before they need replacing?
The LEDs are rated 60,000 hours at L80, meaning they still put out 80 percent of initial lumens at that point. Extra High Lumen (XL) packages are rated L70 at 60,000 hours instead. For serviceability the LED is affixed to a removable heat-sinked gear tray, so the light engine and driver come out as an assembly rather than the whole fixture coming off the ceiling, and a QR code label on the housing ties the unit back to its build record.
11) Where can I get the full spec sheet for the Columbia LXEM before I submit it?
Columbia publishes a spec sheet for the LXEM at https://zensupply.com/content/pdf/columbia/COL_LXEM_spec.pdf, which is what you attach to a submittal package alongside the photometrics. Key values a reviewer will look for are on it: 120-277V input, 80+ CRI, 3500K/4000K/5000K, and efficacy up to 150 LPW.
