589 looks so natural and relaxing too unlike most lasers.

Re: Various lasers 4 sale mw is power 475mw

Dragon lasers is good my spartan 50mw gets 62mw peak i had it since my 21st birthday and it rolled off my bed last month and landed 3 feet on not my rug but hardwood floor. I was like NOOOOOOOOOOOOOOO but it worked and LPMed fine. Mine uses 1.89amps. 30mw should get you a good beam mine is...

Re: Various lasers 4 sale Which ones I want a class 4 405nm. one with the best duty cycle? Needs to be focusable. my 475mw is only 280mw.

Yeah but this is low powered I don't think the dioides will go but the lack of pics means it probably isn't white.

custom colors. It's 12 volt RGB 300mW White Laser Module Red 650nm 100MW Green 532nm 50mW Blue 450nm 150mW | eBay

Pretty sure they're all the same.

Yeah I wouldn't register it unless you have like a 589 then just for the insurance it's yours. Any normal color is asking to be blamed when some drunk frat boys shine a green or 445 at a helicoptor and all they get is a crappy video or none at all. You better hope you were somewhere off campus...

This only slightly less dumb than that stupid choking game fad they even talked to us about it back in HS. WTF is wrong with some humans. I swear everytime some one comes up with an idea someone makes a double dumbassed idea. Like I learned today about this new gimmick. People will yell freeze...

I used my lasers at my astrolab I had never had an issue. Just never let anyone handle them. My professors green was not enough to cut through the stadium lights. My 589 came through. Vega was even dim looking. Registering them as a weapon implies something sinister about lasers imo...

Birds can see UV too. I read that hawks use this to hunt mice and they see the urine trail to find them. so 405 would look like maybe 638 per mw or maybe brighter. No wonder 445 would scare them off since It still has a violet tint to it unlike 473.

300mw of 405 should be fine if you have good optics. I've burned white stuff with a 50mw 405 with a lens that gives the beam a very short focus. even light matches. 405 is amazing at burning. 808 is worse than reds even since most organic things diffuse them or reflect alot or might even be...

any brand name I.E sony or samsung unprotected with the nitecore i2 is good. it cuts at 4.18. pretty sure the lighter ultrafire is a smaller cell. i'll weigh it later. I read salt was good for other akali metals. beware of fakes cause of e-cig sites saying it's a sony.

i pray it's not a lose connection to the driver thats drawing current do they feel warm? one warmer than the other?

Let me tell you this that's getting into UVC you should be glad our ozone layer blocks uv-c I have a 13 watt clear mercury lamp in an enclosure and you must wear googles (laser are fine) and cover your skin otherwise it will smell like a combination of dead and burnt skin. Even a few seconds of...

I have a grey ultra fire that is pretty heavy and has a low voltage cut off ( i ordered it years ago domestically) but the blue one i got with my red 301 was a joke I felt like I was gonna break it. Measure the voltage with voltmeter before you use it it should be 4.18 and take it out 5 mins...

my spartan gets 62 mW it dosen't drop in the cold atleast not visiblly. it rolled of my bed like 12 days ago. I was like ohhh crap this is never gonna work after falling a few feet onto a hardwood floor. But the LPM didn't change damn tough laser.

This is why you don't by cheap ones. https://www.amazon.com/gp/customer-reviews/RDCJISNYSZ3I4/ref=cm_cr_arp_d_rvw_ttl?ie=UTF8&ASIN=B01983RXYK

2 CR2s and a charger that i use they'll only 200mah but they work better then a 500mah no name from a o-like laser also charges CR123s https://www.amazon.com/Watson-Charger-CR123A-Lithium-Batteries/dp/B00HCQFPKA/ref=pd_sbs_421_2?_encoding=UTF8&psc=1&refRID=4V9SKCGV4P8KG8YYZ6Z6

I'm pretty sure it's a voltage spike or Electrostatic discharge.
