Buying A Light While Sick?

I was sick and had an IV that ran out. Someone told me to drink the remainder of my dog's IV because it was good for me. I went to KMart for some big fancy halogen light i needed. The cashier told me it will wrack up electric bills and makes a loud buzzing noise. It was also expensive, but I paid my 7.99 and bought it anyway. That's all I really remember.
