The warmth of the lights could be felt.

It had five lights, two on each side, and one on the front, like a delta shape.  Absolutely no sound at all, moving very slow, and the heat from the lights were warm on the bare arms.  It was approximately, just guessing a couple hundred feet overhead.
Slowly moving overhead, the black form of the delta shape could be clearly seen.  Then maintaining the same slow movement, diappearing over the trees.
