watts = volts x amps
are the bulbs in serial or parallel?
what is your transformer rating?

Watts = Volts x Amps
Watts = Volts x (100 x 0.44)
Watts = Volts x 44 amps
That is huge for xmas lights.
Are you sure about the 0.44A? Are these run from the mains (110v) or from a transformer at a much lower voltage?

Well, assuming you are on USA volts (110V yes? that is just so wasteful of electricity) the power consumed will be
0.44*110*100 = 4840 Watts
Which is a huge amount. Are you sure of the power rating of each bulb? Far better to use LEDs at a fraction of the power

Why is the voltage of american electricity system not 110 V?
44*110= 4840 watts

P = U.I = 110 * 100 * 0.44 =4840W

105.6 watts. in America they would be 48.4 watts at 110volts or 96.8 watts if the voltage is 220volts.
Happy Christmas.

In the united states they have 110V(ac). So, 110x0,44 = 48,4W
