Are these $3.50 lights "cheating"...they are new, but I think, allowable.

75% off after Christmas, they were certainly cheap enough, but they were new. However, I wanted some battery-operated LED lights for my mantle and for seeing if I could use them for an art/craft project I hoped to make and eventually sell.
The technology is so new, I don't think I'll find used battery-operated LEDs...at least not for a few years, so I am allowing myself this purchase. I only bought one, even though I could have used at least two...I figure I'll experiment with the one and if it works out, there's always next year.
