Product identity

The Federal Signal SLM200B is a blue LED warning light built for industrial and vehicle safety. It operates on dual-voltage input from 12 to 24V AC/DC or 120 to 240V AC. The polycarbonate housing and Fresnel lens carry IP66 and NEMA 4X ratings. Flash rates run at 85 or 120 flashes per minute with 70 candela output.

Mounting versatility

The fixture supports deep, shallow, twin, pipe and dual mounting styles without extra brackets. A 50,000-hour LED life reduces lamp replacement cycles. Current draw ranges from 70 to 510mA depending on supply voltage. The wide operating range spans -22 to 122 degrees Fahrenheit for cold-storage or outdoor use.

Pre-installation checks

Verify that your supply voltage matches either the low-voltage or mains range exactly. Confirm the chosen mounting surface suits one of the listed mounting styles. Ensure the 3 29/32-inch square footprint and 4 15/64-inch height fit the allocated space. Wiring must accommodate the stated current draw at the selected voltage.

Questions about this item

How often will the LED module need replacing if the light runs continuously?

The LED is rated for 50,000 hours of operation, so replacement would only be needed after several years of continuous use.

What limits the flash rate when the unit is powered for long periods?

The flash rate is fixed at either 85 or 120 flashes per minute and does not change with sustained operation.

How much current does the light draw when it runs all day on a 24 V supply?

Current draw ranges from 70 to 510 mA depending on the voltage applied, and the IP66‑rated polycarbonate housing handles the resulting heat without active cooling.
