Dary, if you want to feel like Luke Skywalker, lay open a black trash bag and hang it like a screen. Put your safety glasses on and have a blast. Nobody unprotected in the room.

Possibly a fire extinguisher along with other safety protocols??
The last sentence on the paper work caught my eye(and slow but retaining mind) and makes wonder about the whole sentence/ paragraph.
It says "maximum operating time......"Actually length of operating time must not exceed"
I wondered and remembered where I have seen this before.
Probably totally off topic but on a battery charger/jump starter , for vehicles.
You know says 2,10,50,200 amp charger.
It said(the charger)"maximum operating time @ 200amp ; 3 seconds.
I believe damage disclaimers followed for "excessive" use?
How long do they say to point that thing for?????

Dary's tank!

It can overheat the LED. I would run it in bursts of 5 seconds most of the time.

I love BBT. One of my favorite shows. I am a mix of all of them, except Penny. And Bernadette.

Safety glasses a must before you pick that wicked thing up.

It doesn't so much burn the plastic as it does melt it. Still a pretty cool effect.

Do not let dust fall into your light hole.

LOL

I also believe that there is too many zeros on that output table. From what you described, I think it's a 20mw laser. A 20 watt blue laser makes a beam like the shotgun I posted. But who knows? I ordered the same one. I'll let you know as I have several to compare it too.

I was was pretty skeptical about the whole laser thing at first but this thing changed my mind ,.. Even burned a spot on my wooden cutting board , I can only imagine what it would do to an invasive black widow spider let alone what it does to the aptasia
Pretty interesting tool ,... Sheldon would be proud

So, I just paid 9 bucks with free shipping for a 20mw laser......straight from the motherland of all things cheapo. I hope it performs like yours!

"Sheldon" would have scoffed and pulled out his UV chemical laser, then blown a whole thru the apartment wall.
