The curve in the old flyer climbs rapidly showing about 93 % peak efficiency at approx 150 to 350 watts, then straight lining it down through/to approx 83% at 1500 watts. It does not start on the chart at 0 watts though which is interesting, it starts climbing at 80% efficiency from the 25 watt line. So at 10 watts (interpolating backwards) you must be at approx 33% efficiency! Hope this helps

I need to show a customer that it is not 94% effecient with a 10 watt ac led pluged into it alone. I am betting that it needs 500 watts to get into the 75 or 80% range. Thanks, Bob
