RAB SHARK4-50NW/D10 – Frequently Asked Questions

1) Can the RAB SHARK4 be hosed down in a food processing plant washdown?
That's what the SHARK4 is built for. It carries an IP66 ingress protection rating for dust and water, so it's fully dust tight and takes powerful water jets, and it's NEMA 4X rated for corrosion protection. Sealing is EVA gasket. It's also NSF Certified by Public Health and Safety, which is the piece a food plant or commercial kitchen inspector will want to see.
2) What is the difference between the RAB SHARK4 and SHARK4M part numbers?
The M is the Marine listing. SHARK4-36NW/D10 and the rest of the plain SHARK4 numbers are the standard UL listed versions; SHARK4M-36NW/D10 and the other SHARK4M numbers are the Marine listed versions of the same wattage and color temperature. If you're specifying for a boat house, dock, or vessel application where a marine listing is called out, order the SHARK4M number. Everything else about the two runs the same options.
3) Will a RAB SHARK4 fixture start in an unheated cold storage room?
Down to -30 C (-22 F), which is the minimum starting temperature for the SHARK4. On the other end it's rated for ambient up to 40 C (104 F). That covers most refrigerated and cold storage spaces, but a blast freezer running below -30 C is outside the fixture's stated starting range.
4) What do I have to specify when ordering a RAB SHARK4 linear LED?
Four things. Wattage, either 36W or 50W. Color temperature: 3500K warm neutral, 4000K neutral, or 5000K cool. Standard or Marine UL listing (the M in the part number). And the driver, which is 0-10V dimming at 120-277V. So a 50W 4000K standard unit is SHARK4-50NW/D10, and the marine version of the same is SHARK4M-50NW/D10.
5) How does the RAB SHARK4 mount to a ceiling or wall?
Surface mount, and the hardware comes in the box. Stainless steel quick-mount spring clips plus a V-Hook with bracket screws are supplied with the fixture, so for a straightforward surface application you're not buying a separate mounting kit. The fixture is 4 feet long, so plan your mounting points across that span.
6) Does the SHARK4 dim, and what control system does it need?
Every SHARK4 configuration ships with a 0-10V dimming driver on 120-277V input, so it wires to any standard 0-10V control, occupancy sensor, or lighting panel with a 0-10V output. The driver is constant current. There is no non-dimming version in the lineup, so you're not choosing between dimming and fixed output.
7) Does the RAB SHARK4 qualify for a utility rebate?
The SHARK4 is listed by the Design Lights Consortium as DLC Premium under DLC version 5.1. Premium is the higher of the two DLC tiers, and it is the qualification most utility rebate programs check against for linear LED. Bring the DLC listing to your utility's program to confirm what their current incentive pays.
8) Which color temperature should I order for a commercial kitchen versus a warehouse?
The SHARK4 comes in 3500K warm neutral, 4000K neutral, and 5000K cool, and all three are offered at both 36W and 50W. 3500K reads warmer and is the usual pick where the space is customer facing or adjoins finished areas. 4000K is the general purpose neutral most commercial and industrial spaces standardize on. 5000K is the coolest and is common in inspection, food processing, and vehicle service work where you want maximum apparent brightness and color separation. RAB's CCT range follows ANSI color uniformity guidelines, so units of the same CCT will match across a run.
9) Do I need a separate surge protective device for these fixtures?
Each SHARK4 has 4kV surge protection built into the fixture, so for typical interior branch circuit work you're covered at the luminaire without adding an external SPD per fixture. If the installation sits on a service known for heavy transients, that's a panel-level decision your electrical engineer makes, not a fixture one.
10) Is the RAB SHARK4 bright enough coming off a wet floor, or will it glare?
Glare control on the SHARK4 comes from a textured, diffuse polycarbonate lens paired with a specular polycarbonate reflector, so the output is spread rather than delivered as a hard point source. That matters in a washdown space where wet floors and stainless surfaces bounce light straight back at the operator.
