Haha you tried... *pat pat* remember it's WL credit, I have to use it on WL stuff. LaserSaber at least makes you look dorky cool. The Phosforce just looks like it'd be a disappointment (unless it can actually give out a good 400-500 lumens with my incoming RT 445nm 3.5W). And 4.0 beam diameter is disgusting... and I doubt the <0.5mRad divergence
4mm beam diameter lends credence to their low divergence claims. Remember that diameter and divergence are inversely proportional, so having a wider beam is better for a tighter beam profile, whereas a smaller diameter beam will result in one which spreads faster. Also, 4mm is very small. Look at it on a ruler or a caliper if you have one. It is very small.
