D1-Radio Hybrid - Battery + Solar-Assisted Sequential Warning Lamp

The D1-Solar Hybrid Radio combines photovoltaic and battery power to significantly extend site autonomy without manual battery changes. A 2 W solar panel paired with an integrated 3.2V / 4.5 Ah lithium battery supplements the 4R25 disposable battery — in optimal solar conditions, autonomy can reach up to three times that of battery alone (up to 900 hours with a 50 Ah alkaline). Radio synchronisation at 434 MHz keeps multiple lamps flashing in sequence across the site. EN 12352 class L8G certified. Shares the same rugged PA-6 body and polycarbonate lens as the D1-Radio, with head-pole mounting
