Keystone KT-CBLED45PS-24B-8CSA-VDIM – Frequently Asked Questions

1) Will the Keystone 45W 2x4 center basket troffer drop into a standard 2x4 grid ceiling?
It's a 2x4 nominal fixture and ceiling mount, so it sits in a standard 2 ft by 4 ft grid opening. Plan the support for 17 lbs of fixture weight, which matters on older T-bar grid or where seismic hanger wires are required.
2) Can one troffer model cover both 120V and 277V jobs in the same building?
Yes. The input is 120-277V, so the same part number wires to 120V tenant circuits and 277V commercial lighting panels. That is the main reason to standardize on it across a multi-building or multi-floor retrofit instead of stocking two voltage versions.
3) What wattage and color temperature do I set on a Power Select / Color Select troffer, and when do I set it?
Selections are made on the fixture at install, before it goes in the grid. Power Select gives 45W, 38W or 30W, with matching output of 5800, 5000 or 4150 lumens. Color Select gives 3500K, 4000K or 5000K. Typical practice: 3500K for offices and healthcare where warmer light is wanted, 4000K as the general commercial default, 5000K for industrial and back-of-house. Pick the wattage from the footcandle target, not the highest setting by habit.
4) Will this troffer dim from our building automation system?
It accepts 0-10V dimming, so it ties into a BAS, occupancy/daylight sensor, or a 0-10V wall dimmer using a low-voltage control pair pulled alongside the line voltage. It is not a wireless or app-controlled fixture, and it does not do forward-phase or ELV dimming, so a standard incandescent-style dimmer will not control it.
5) Does this troffer qualify for utility rebates?
It is DLC qualified, which is what most utility prescriptive rebate programs require for commercial LED troffers. It is not on the DLC Premium list, so any rebate tier that specifically calls for DLC Premium would not apply. It also does not carry Energy Star.
6) What is the 12V aux power on the Keystone center basket troffer used for?
The fixture includes a 12V auxiliary output, which is there to feed an add-on component such as an emergency battery backup or sensor module rather than to power the LEDs. If you are specifying emergency egress lighting in the space, that aux feed is the hook-up point, and the accessory itself is ordered separately.
7) Is the color quality good enough for a healthcare or retail space?
CRI is greater than 80, which is the normal commercial benchmark and is adequate for offices, classrooms, patient corridors and general retail. For spaces where color judgment is critical, like merchandising of fabric or paint, or clinical exam rooms, a 90+ CRI fixture is the better specification.
8) How long before we have to relamp this LED troffer?
Rated life is 50,000 hours, and the LEDs are integral rather than a replaceable module, so there is no lamp or module to swap. At roughly 12 hours a day that puts it beyond a decade of service, which is why facilities groups use it to get relamping off the PM schedule entirely. At end of life the fixture is replaced, not re-lamped.
9) Can I order a single part number and set it per room instead of ordering several SKUs?
Yes, and that is the point of the selectable design. One model, KT-CBLED45PS-24B-8CSA-VDIM, covers three wattages and three color temperatures, so a property manager or MRO stockroom can carry one line item and field-set it for an office at 4000K and a warehouse aisle at 5000K. It cuts the number of SKUs on the shelf and removes the risk of ordering the wrong Kelvin.
10) What does the fixture look like installed, and will it match the troffers already in our ceiling?
It is a center basket troffer with a white housing, so the trim reads the same as typical white-painted troffers in a commercial grid ceiling. The center basket diffuser spreads light off the center element rather than through a flat lens, which gives a softer ceiling appearance than a flat prismatic lensed troffer. If your existing openings are flat-lens units, expect a visible difference in brightness pattern across the ceiling even at matched color temperature.
