I contacted laser lands about the purchase and Mary insisted I send a pic. I send a picture showing the laser barely even visible point blank against a white wall, I mean just the most pail dot imaginable. If I pull back 10 or so feet, it's gone.
The emails after that was her telling me how a 5mw 450nm is ordinarily that bright because it is less visible than 635nm. She continued sending me visible spectrum links to show the visible wavelength. A complete joke. At this point, laserlands wins because I just simply don't have the care or energy to keep asking for a new laser to replace the defective unit and being told it is <5mw due to customs.
dear customer
we use osram 80mw or sharp 110mw blue laser diode in to produce this laser pointer.
because of the law we have to reduce the current it to let the output <5mw.
otherwise, the laser pointer cannot pass through the customs of yours.
I can fully understand that you need a very bright laser pointer. we can also produce the high output laser pointer. even we can simply use the default output of the laser diode to produce it.
but there is a problem--it may be held by your customs.
can you open this link

here I have share blue 80mw and green 50mw laser pointer video here.
but when we outport the laser pointer--you know we have to minus the output to let it pass through the customs.
it is really pity.
can you adjust the current by yourself? some of our customers open the case and increase the current on the driver although I strongly donot recommend they do it like that
that is another conseption of the wavelength.
you can google a spectrum. the blue is not as bright as red by human bare eyes comparing with red and green. here I attached a spectrum as well.
