Oh really? You said that like 20 times already. Stop saying that if in the end it turns out to be a lie or a broken promise. I know that sometimes you can be busy as everyone else on this world but after more then 1 month (oh god it's almost 2 months now) since I ordered the laser, there is...

Well it turned out that Thejoker301 doesn't want to send me the power certificate even after telling him hundred of times to do so. Just a reminder for everyone: If you planning on buying a laser from Sci-fi, be prepared to get really terrible communication but you will get your laser delivered...

Interesting. I'm all about brightness and good beam divergence so I will just stick with the G2 lens. Maybe in the future there will be new / better lenses. :) I think my laser outputs ~200-230 mW because the way it can burns black stuff like plastic. I compared it to a few videos I watched on...

Yesterday I received my new SF501B 520nm forest green 170-300mw laser from Sci-fi for 134$ without shipping cost. Laser specs: - PLP-520-B1 520 nm laser diode - Power output 170-300 mW - 405G2 / G9 / G1 (can't tell which one I have) - 60 sec on / off duty cycle - 2 x 18430 battery - WF-501B...

That's why we can't have nice things. You can be only be so smart but for stupidity... there is no bottom (talking about people who point lasers at other people of course). I can't imagine how it must feel to be blind and I hope I never will be.

I also ordered the same laser from Sci-Fi. My safety glasses and batteries are ready. I just can't wait to get it in my hands :beer: I'm also planning in getting a +1W green laser later this year or next year and oh boy how bright must the +1W green laser be if even the one I own right now...

Okay so the 3 element glass coated lens gives a better beam specs but lowers the outpower a bit but a single glass coated lens gives a highter output power. would this do the job, I searched a bit and found this: Laser Coated Glass Collimating Lens/M9P0.5 Metal Frame | eBay

This makes me think that the best lens you can get is the simplest one. A plastic or a acrylic lens. And if thats true what "Fiddy" that the 3 element glass lens outputs less power than the acrylic one, Then the most expensive lenses are obsolete O_o? The lens i'm currently using on my red...

I have sacrificed a lens from the laser housing bought on dealextreme ( it was scratched already and blocked most of the laser beam) and then I turned on my 1.6W blue laser and made the beam diameter small as the red one and shined though the lens and first I though it was a glass lens but...

Hello! I couldn't find any comparisson between a 3-element glass lens and a normal lens found on a 5mW red laser module: 3-element: 3-element Glass Lens Coated for 630-660nm Red Lasers | eBay & normal lens: Red Laser Module - Focusable Dot (3.5V~4.5V 11.89mm 5mW) - Free Shipping -...

Re: For sale: NEW 1W-2W 445nm 501B lasers from $110 I think the blue laser diode itself costs ~60$, if I'm not wrong.

Re: For sale: NEW 1W-2W 445nm 501B lasers from $110 I don't think a blue laser with power ~1.5W can burn stuff like leaves or paper more than 5m away. At last mine can't and it outputs 1622mW "max". A red laser with power more than 300mW is better at burning at long ranges. Blue lasers...

Re: For sale: NEW 1W-2W 445nm 501B lasers from $110 Hi! If you take a look 1-2 pages back I posted two screenshots of my laser made by Blord. And I confirm that Blord is a legit seller. U don't have to worry about being scammed here. Because scammers don't live long on this forum. Which...

Re: For sale: NEW 1W-2W 445nm 501B lasers from $110 nice choice of music xD Where did you get the tripod? I want it to.

Re: For sale: NEW 1W-2W 445nm 501B lasers from $110 Here are some screenshots of my laser: 20130302_180319 - 20130302_180319.jpg - Minus 20130302_152035 - 20130302_152035.jpg - Minus at night, when i turn it on in my house, the laser is sooo bright :)

Re: For sale: NEW 1W-2W 445nm 501B lasers from $110 When I recieved the laser last friday, the LD driver was half dead until it died after 30mins. Now it works so great and the beam....:drool: I will post some screenshots tomorrow because later today I have Prom :)

Re: For sale: NEW 1W-2W 445nm 501B lasers from $110 I will get my laser from repairs tomorrow and I hope it will. Then I will post some screenshots. Can't want :)

Re: For sale: NEW 1W-2W 445nm 501B lasers from $110 The batteries are perfect. I tested them on a 9V LED. I sent you a PM.

Re: For sale: NEW 1W-2W 445nm 501B lasers from $110 You wont believe this but my brand new laser died. When I turned it on for the first time the laser beam and the dot wasn't that bright as I expected. I took ~7sec to burn a hole though a CD case and after like 30mins after I first turned the...
