RAB SHARK4 – Frequently Asked Questions

1) Does the RAB Shark linear LED fixture run on 120V and 277V both?
The Shark runs on any voltage from 120 to 277V off the same driver, so the same fixture goes into a 120V office circuit or a 277V warehouse feed with no separate transformer. The driver is constant current and both the 4ft and 8ft versions are ordered with 0-10V dimming built in.
2) What wattages can I select on the RAB Shark 4ft versus the 8ft?
Two lengths, each with its own wattage set. The 4ft (SHARK4) is field-selectable at 50/40/50W and the 8ft (SHARK8) at 100/80/60W. You pick the wattage at install with the selector, so one stocked fixture covers several lighting layouts instead of ordering a separate SKU per wattage.
3) Is the RAB Shark LED fixture dimmable, and with what kind of control?
Dimming is 0-10V, which is the standard low-voltage control protocol for commercial LED drivers. That means a pair of purple/gray control conductors pulled to the fixture alongside line and neutral, and a 0-10V compatible dimmer or lighting control panel, not a residential phase-cut wall dimmer.
4) Can I use the RAB Shark in a washdown area like a food plant or kennel?
Yes, the Shark is a washdown-family linear fixture, which is why it shows up in food processing, commercial kitchens, car wash bays and similar wet or frequently hosed spaces rather than as a plain open strip light. The sealed body is also what makes it usable in dusty warehouse and industrial work where an open strip would foul.
5) Do I have to order a different fixture for 3500K versus 5000K?
No. Color temperature is selectable on the fixture itself, so one part number covers the CCT options and a crew can set warehouse aisles and an adjacent office area to different color temperatures out of the same box. That cuts what a property manager or distributor has to stock down to two SKUs, SHARK4 and SHARK8.
6) Will the RAB Shark qualify for a utility rebate?
It is DLC listed under DLC version 5.1, which is the qualification most utility LED rebate programs key off. Bring the DLC listing and the model number (SHARK4 or SHARK8) when you file the rebate paperwork; the program administrator verifies against the DLC Qualified Products List.
7) How long will the RAB Shark LEDs last before they need attention?
Rated LED life is 100,000 hours. Run 12 hours a day, that is over 20 years of service, which is the argument for putting these in high-bay or hard-to-reach locations where relamping means renting a lift. There is no lamp to replace, the LED board and driver are the serviceable parts.
