With this penlight, Brightness is written with a capital B.

The size of a ballpoint pen, the P4 looks rather ordinary when you place it securely in your shirt pocket using its handy clip. But its light output is more than impressive: Up to 18 lumens are cast into the darkness extending as far as 25 m. And its special lens creates a full beam of light with an unmistakable blue edge.
