Author: Ohad A - Israel - April 2008 I've just received the Spartan BP-20 – my first blue laser ever (first time I even see a blue laser not in a video).
I was really surprised by its brightness and power.
It's very bright – much more than I expected, more than a red laser of even higher output. (though less than green which is expected). The beam is clearly visible at night, and it's simply beautiful.
I was able to burn with it using a focusing lens (singe black plastic with smoke, like with green or red laser). Didn't expect that from a 20-30mw average laser, with batteries not fully charged…
I'm very happy with my new laser.
And a few good words on Dragon Lasers support:
I sent a couple of questions on the batteries and charger and received answers within minutes.
I also used the online support chat – it works, very nice!
So in conclusion – I'm one very satisfied customer.
Author: Charlie O UK July 2011 tested the Spartan on a laserbee 2.5 and with a fully charged ultrafire 18650 3200mah protected battery.over a 3 minute period.The results were 40mw peak and a steady 35mw until the battery drops off.
I set my lasers at maximum distance from the thermopile for consistency of readings and at max dis. so they ,in theory, should always give the lowest value.
Well built host with attachment screw thread capability . Arrived within a couple of weeks. Excellent service, keep up the good work.
