So what you are trying to say Andrew, is that a pinball machine that is plugged into a wall, with 100 normal bulbs, uses alot more power than a machine using only LED's.

Therefore, if u were to put the machine in a test mode, say with all bulbs flashing, you could measure the consumption.

Then, you could measure the same draw, with the same machine that has only LED's and work out the difference.

So led's will save on power, but overall, only power usage on the lighting circuit which is only a part of the overall power consumption.

** We might kit out 1 x star trek next gen with only LED's, then kit out my other STNG with the std bulbs, and measure the difference. !
