Smashed
I received my bulb in timely order; It had been placed loose in a box with a heavy digital ballast, there was no protective packaging and as a result it was smashed.

La lámpara ya me llegó fundida. En este caso, desaconsejo su compra, ya que es mejor probarla en un establecimiento físico. Mala compra
