Ответ:We asked the manufacturer on this one. They did not have an exact definitive answer. Here was their reply: "They're made to work on 12 to 14.8 Volts DC. That's the normal range of voltage found on most "12 Volt" systems - like cars, trucks, aircraft, etc...If the customer has a 16VDC power source, it will work but may shorten the life of the LEDs. It's hard to say by how much - it depends on the particular system."
