My wife bought 3 Himalayan salt lamps. One is set on the left side of the front door facing out is South direction. the bulb is red in color and is on 24 hours. The second is upstairs in the study room and the bulb color is orange and facing south. The third is facing East in the playroom and red bulb color. Are these okay to have in the house, or do they release bad energy? Response is appreciated.
