This thread shouldn´t die. My contribution below:
#don´t simply trust Ebay / Chinese laser power listings. In both directions (low/high power)
When I got my first 1mW laser back in 2009, I only knew about the blinking reflex for lasers >5mW. I played around with it as I thought it´s totally safe.
Now I know that the laser had at least 30mW.
#seeing no green light coming out of a 532nm, doesn´t mean that it isn´t emitting photons
When it is too cold for producing green light, these cheap green pens sometimes produce only +50mW of IR.
Once, back in 2010, when I got two DinoDirect claimed 100mW pens (in the winter-time) I started them, but saw no output. I then carefully looked closer and saw a faint red-light. Back in the days I knew shit about IR. I thought that they sent me a very low powered red laser. Put after putting it onto my LPM, I read +60mW of this "low powered red laser". Once it was heaten up a bit, it turned to green output.
#there are also non-rechargeable 3.6V 14500 cells out there
