Hard to say exactly, but I think it's about 30 to 60 minutes. :tinfoil:

yeah. some people thought it was fully charged and used it, end up under charging the battery and decreasing it's lifetime

Do you mark your lasers as gifts? I was so excited about the 100$ deal that I actually forgot about the import taxes :yabbem:
Thanks!

funny moment --- had goggles on which makes the beam look like an orange luminous speck/point ... i put my hand out in front of the beam and immediately it felt like hot lava on my hand ... like a soldering iron poked onto it ...whew... !

Mine just arrived today, it is a beauty I must say.
Just one query, when out of focus I have a rectangle as a opposed to having a circular point whilst in focus. Is this the norm for it.. right?

yes Marcusss --- mine is the same way and the focus ring is pretty loose --- it will de-focus fairly easily but I know that issue was addressed, prior with plumbers' tape or something ?

The diode its self has a bar which produces light so without collimation you end up getting a rectangle like "dot"

Multimode diodes do that... Its like 3 lasers in one going through the same diode do they all don't hit the target in the same spot exactly.. but when up close a small rectangle has the same power as a dot the same size.
These are so powerful that even a rectangle can do a number on a balloon.... It can pop one at 30 feet in about a second... closer is instantaneous.

I"m new to multimode lasers too... if I explained it wrong, I"m sure someone will correct me.

Re: 1-1.2 watt 445nm lasers CHEAP $180 ****OUT OF STOCK****

good times last night with the Yob445 ... a friend came over and we put goggles on and beamed away ... he was quite impressed like "wow, is this legal ?!" :thinking:

I demonstrated the beam up into the sky , as well . good times .
did a side by side comparison with my Rayfoss 532 green laser, quite a nice contrast.
the 445 beam is wider/thicker but doesn't seem to travel quite as far into the horizon as does the 532 ...

:friend:
