Hokay... so i bought a 20$ lamp at wally world last mont for when it was dark before DST. it doesnt work well. its a coleman blue lamp that has a fluorescent tube inside. i took it out and 2 days later [the lamp came inside after i took care of the chicks] it stopped working. sitting by the door, it only works on half the bulb. i dont need it anymore, but could i fix it somehow [cheap?] also would normal tree lights work for the coop? or do i have to use outdoor ones?
