Phase II® strobes are a popular family of large strobe beacons. Phase II models are designed to sense ambient light levels and gradually adjust the light output to meet existing conditions. These strobes feature an impact-resistant, hermetically sealed base that supports the circuit board and provides superior resistance to moisture. All models are multi-volt (12-48 VDC) and protected against reverse polarity. Phase II strobe beacons include a five-year warranty and meet SAE J1318 requirements.

Heavy Duty models feature a gel-filled base that completely encases the power supply for extra protection against vibration and moisture.

Phase II 162 models are designed specifically for Class 1 applications. This strobe features a powerful 20-joule power supply and meets CAC Title 13, Article 22 (amber or clear domes) and SAE J1318 (amber, red or clear domes).
Phase II 1262 and 1682 models are designed to sense ambient light levels and gradually adjust the light output to meet existing conditions. 1682, double flash, models and 1262, triple flash, models switch from 20-joules (high) to 10-joules (low). 1682, single flash, models and 1262, double flash, models switch from 16-joules (high) to 8-joules (low). 1262, single flash, models switch from 12-joules (high) to 6-joules (low) and are designed to meet European specifications of 120 flashes per minute.
