Where to buy Blue laser

[hynek6cz]

Hi,
I wanna to ask where can i buy cheap blue laser and if it could have in nighttime visible beam.
It's only for effects, no for burning so it can be some cheap shit
I had already some cheap "200mW" green laser so it was i think about 50mW, and i tune it and put into it about 4,2V instead of 3V and it was like laser sword but now it's not working so I wanna try some blue
Thanks

Well most pens labeled "<5mW" Are very overspec when it comes to blu-ray. The two one's I've gotten off of eBay and Amazon have both had visible beams at night and could light matches when focused using an external lens. Obviously 5mW of 405nm light is very hard to see so they're expected to be overspec. But I've heard from several members the average is between 60-70mW in reality!

405 is not blue.
445 is blue.
445 don't come verry cheap
