Pricey, but high quality clock. I put it on my bench power supply and can confirm it draws less than 3mA at 12V, and has kept accurate time for 2 days now. The clock is powered via two 6-32 studs on the rear and can run on 8-32 volts. It weights 5.34 oz. The backlight uses two small incandescent bulbs on a PCB module that attaches to the top edge of the clock and is powered via two wire leads about 12 long. It lights the face from above and draws 70mA in operation (the 12/14V version). The light module is attached with two 4-40 flathead screws. These screws are not self-tapping, and thread into unthreaded plastic holes about 0.25 deep on the top of the clock. After struggling a bit with the screws, I used a 4-40 tap to thread the holes first, and then the screws went in cleanly and securely.
Per the manufacturer: No. This item is bezel lit (edge lit), not backlit.
This clock will require a constant power source. If power is removed it will have to be reset.
