NO and NO!
The lighting in most venues don't give you much in the way of available power (and they vary greatly in color output) and in winter in most parts of the US you won't be able to run the competition outside where it might work. Even using solar to recharge the batteries would require a large array to get any significant current vs. time for the batteries we use. (remember 4- 6 amps for several hours per battery depending on discharge state)
