I have 16 mini trees made by using floral wreath stands which can be found at lots of home decor stores, like Garden Ridge, Joanns, etc. I use 3 100 ct incans on them - one each of red, green, and clear. My goal is to replace / rebuild them using LEDs since If I turn all the lights on all 16 trees at once they pull over 18amps. In contrast everything on my house - roof, gutters, windows, doors, porch columns, etc and my mega tree use less than 2 amps total when all on. That tells you the difference with using LEDs for lights.
