If someone has a Kill-A-Watt Meter or a Watts-Up Meter, can you find out what the power consumption of the Bridge unit is under normal conditions?

If you can plug in the bridge into the Kill-A-Watt and find out what the watt consumption is when the lights are all on and also when all lights are off and see if there's any difference between the two numbers.

  • I asked Philips about this. They say that the power consumption of the Bridge is three watts. Also, the standby power consumption of each lamp unit is 0.4W. Full power for each lamp is 8.5W.

    They also take two seconds to reach full brightness. That's actually quite nice if you've just woken in the middle of the night!

    I tested this. OVer a 13 hour period with a few times having the bulbs switched on and off wirelessly the total energy consumption registered as 0.01kWhr, which is the minimum value the Kill-a-watt can display. This equates to about 7kWhr per year. Note that because this is at the limit of the Kill-a-Watt's resolution, it could be 50% higher or lower than this.

  • In my opinion, I would say that the bridge under "normal" conditions would be in an idle state until scheduling or a change in the lighting would make the bridge communicate with the lamps. Under conditions outside of these it should, as most devices do now, go into an idle mode and consume less. It would be an interesting experiment to see if that is how it functions. A meter such as that should give you a good idea of what happens with the bridge over time. If serious data recording and power consumption history is your aim, the watts-up meter pro has a USB connection and PC software and will allow you to transfer the data from the meter to your PC for tracking.
