1) I was out walking my dog Zeppy for a 25 minute High line Canal stroll. 2) The white solid beam of white rectangle light landing near the front of my Dog, Zeppy and I. 3) I had no idea initially. 4)This "object" just appeared out of thin air and I and my Dog froze as we were approximately 20 feet away. 5) I was semi appalled and numb by the experience, I felt immediately,that I should have not seen or viewed this object as if it did not belong here physically. Motions were stationary. I told two friends immediately about this shaky encounter. 6) It literally shut off like a light switch would.
