Amber LED Beacon for 12-24V Systems

The Federal Signal SLM100A is a new amber warning beacon built for outdoor and industrial use. Its LED lamp delivers 20 candela of light output across a polycarbonate Fresnel lens. The housing carries an IP66 and NEMA 4X rating for dust and water protection. It suits vehicles, machinery or fixed installations needing a compact visual alert.

Operates on 12-24V AC/DC or 120-240V AC

This single voltage range determines whether the beacon matches your power supply. The unit accepts low-voltage AC or DC from 12 to 24 volts and also connects directly to mains voltages from 120 to 240 volts AC. Current draw spans 70 to 510 milliamps depending on the input used. Verify your source voltage before purchase.

For fleets and facilities needing a rugged amber

Maintenance teams, plant managers and vehicle upfitters gain a beacon rated for -22 to 122 degrees Fahrenheit with a 50,000-hour lamp life. Deep, shallow, pipe and twin mounting options cover most brackets. Buyers who need a different colour, higher candela output or a synchronous flash pattern should look at other models.

Questions about this item

How bright is the 20 candela output when the beacon is mounted on a vehicle?

At 20 candela the amber LED meets SAE Class 2 visibility requirements for warning use, providing a distinct flash that is clearly seen in daylight and low-light conditions at typical road distances.

What does the 12 to 24 V AC/DC power range mean for wiring the SLM100A?

The beacon accepts any supply between 12 and 24 volts AC or DC, drawing 70 to 510 mA depending on voltage, so it can connect directly to vehicle electrical systems or low-voltage AC transformers without a separate converter.

Which mounting styles does the deep dual-pipe base support?

The deep dual-pipe base fits shallow, twin and standard pipe mounts, allowing installation on flat surfaces, vertical pipes or twin-stud brackets without additional adapters.
