i captured beam shots from a youtube video. the first / top one is Philips LBL, the Second one is Dosun D1 and the third one is a Photoshop composite i made of the two mixed in 50/50 ratio.
the third one represents what both lights would look like together, except that of course both lights together would have double the brightness, whereas the photoshop composite is only the average of the two beams, not the sum of them.
