1. When you have a good lens that is well ajusted... over 100m (300 feets)

2. 5 minutes full power + 15 lower

3. I didn't have time to use it against zombies... I'll try later

4. Yes I saw this video (by KipKay) He's got a laser lighter too... but a 100mW plastic Bic lighter =P

- M-140 laser diode + module: $54
- buck/boost: $20
- G2 lens: $36
- batteries: $4.3 each

Or a 80W CO2 laser for a cannon

And a lot of money...

I don't have a high temperature thermometer.
The only thing I know is that it melt tin (check the end of the video).

You could use it as an ignitor for a spudgun if you use it to light a match or something else inside the spudgun =P
