RAB KNOOKFA32W – Frequently Asked Questions

1) What lengths and wattages does the RAB KNOOKFA undercabinet light come in?
The KNOOKFA is ordered in four lengths, each with its own dual wattage setting: 8 inch (4/2W, KNOOKFA8), 16 inch (9/5W, KNOOKFA16), 24 inch (15/7W, KNOOKFA24) and 32 inch (16/8W, KNOOKFA32). Pick the length that spans the cabinet run, then set the wattage in the field to match the task level you want under it.
2) Can I use the RAB KNOOKFA undercabinet fixture on 277V commercial power?
Yes. The KNOOKFA runs on universal 120-277V input, so the same fixture works on a 120V residential kitchen circuit or a 277V commercial lighting circuit. That is what lets a property manager or MRO buyer standardize one part number across both a leasing office and a tenant unit instead of stocking two.
3) What color temperature is the RAB KNOOKFA, and can I match it to fixtures already installed?
Color temperature is selectable on the fixture from 2700K warm white through 5000K daylight, so you set it at install to match whatever is already in the room rather than ordering a specific CCT. Useful on a remodel where the ceiling cans are one color and the undercabinet run has to blend in.
4) How much clearance do I need under the cabinet for the RAB KNOOKFA?
The housing profile measures 1.38 x 3.94 inches, so it tucks against the underside of a cabinet without eating into the working space above the counter. Check the depth against any face frame or light rail you are hiding it behind before you lay out the mounting screws.
5) Does the RAB KNOOKFA come in white or a wood-tone finish?
Both. Every length is offered in Brown and in White. The brown units carry the plain part number (KNOOKFA24) and the white units add a W suffix (KNOOKFA24W), which is the only thing separating the two on an order form.
6) Why would I choose two wattage settings instead of just buying a lower-output fixture?
The dual setting lets one part number serve two jobs. Run a 32 inch KNOOKFA at 16W over a food prep counter where you need real task light, or drop it to 8W for retail shelf accent or a hospitality room where the same fixture would be glaring at full output. A contractor carrying one length on the truck can dial it in on site instead of guessing the output at order time.
7) How long do the LEDs last in the RAB KNOOKFA undercabinet light?
Rated LED life is 50,000 hours, driven by a constant current driver that holds output steady over that run. For a facilities crew that matters more than the fixture cost: at typical kitchen or work-surface duty cycles this is a fixture you are not sending a tech back to for years, and there is no lamp to stock because the LED is integral.
8) Will the RAB KNOOKFA work for commercial task lighting, not just residential kitchens?
It is built for both. Common uses are kitchen prep counters, office desk and work surfaces, retail merchandise display, commercial food service, healthcare work surfaces, and workshop benches. The 120-277V input is the deciding detail for commercial work, since it drops onto a 277V circuit without a separate fixture type.
