Edit: I started this topic with the belief that Spymodex's new "300mw professional Ultra high power red laser pointer" was actually just a powerful LED flashlight with some smart optics to mimic a true laser -- yet another laser scam. It turned out that I was wrong, so keep this in mind when reading the following lines. BTW, it was also a good lesson for me, teaching the simple truth that no matter how much we know, there's still a lot more to learn. And the more you learn, the more you realize how little you actually know. :)



Hi guys,

Today I received the "300mw professional Ultra high power red laser pointer" that currently sells on eBay at an initial price of GBP 79 ($155). I actually got mine for that very price (no one else bid on it,) but some of these have been sold for GBP 100+ ($200+). Unfortunately I can't post a link to it, but you can easily find it anyway (even on Google.)

I bid on this one on impulse -- it was really stupid, even if only because I always had been having strong suspicion against descriptions identifying something as "professional." Unfortunately, I did the usual research only after I had already placed my bid. Anyway, here's the "laser" here with me now.

At first, it looked not too bad. The only thing I could compare it with was my Crimson Trace LaserGrips pointer. It is only 5 mW peak power, of course, but the "professional laser" really looked a lot brighter. Definitely not 300 mW, but perhaps at least 50 mW (I already expected something like this.) So far so good.

But then I decided to take a closer look at the "laser" construction. I'm sure you notice that I'm putting "laser" in quotes. The big head, from which the "laser" beam comes out, actually rotates, and is, in fact, used for focusing. Not quite what a laser needs, but well, still nothing that wrong. But the real surprise was waiting beneath that head. I took it off, turned the "laser" on, and... Hmmmm, why does it look like an ordinary flashlight?! No beam at all, just diffuse light. Either I don't know anything about lasers, or this was just a simple LED, albeit a bright one.

Actually, I should commend the optics used. The lens and the covering glass seem to be of high quality, being even coated. The final effect does indeed look very much like a laser beam, and is easily seen in the dark. It can definitely be used as a pointer by the astronomy hobbyists. A quick test showed that the red spot is extremely bright (although perhaps 10s of cm in diameter) on a building that's ~ 400 meters away. I don't know if that's a good result, really: as I said, I don't have other serious (true) lasers to compare with, but it does seem impressive, at least on its own. The body is also at least as solid as it looks on the pictures: not anything exceptional, but not very cheap either. Oh, and the "laser" can't ignite matches, of course.

Impressive or not, though, this is highly unlikely a laser -- please correct me if I'm wrong. And I paid 180 bucks calculating in the shipping. So, now I'm thinking: is it worth all the bother with sending this back for a refund, or I should just learn the lesson I already knew anyway (don't buy anything before doing research; and even then don't buy it until you do more research,) and enjoy it as an interesting, even if expensive toy. On a positive side, it could double as red light torch, although, again, quite an expensive one.

Of course, I understand this is really a personal decision. Yet, it also involves other people as well -- if I say to myself "well, whatever", that guy shane.dominic will continue happily selling bright LED flashlights as lasers. Yet again, most people might just as well be happy with them, lasers or not quite so.

I can post pictures when I get back home, if you're interested. One more thing to add: the "laser" is powered by a single 18650 rechargeable battery, and a charger was supplied as well.

Many thanks in advance for your comments.

Cheers,
Luchesar "Bilbo" ILIEV

Re: Spymodex 300mw Ultra power red laser (read: LE

I do NOT have the unit in front of me, but some of your assumptions are incorrect. A laser does indeed need to be focused, especially a red. Without a lens a red laser diode gives of a "blob" of red light. When you looked under the "lens" what did you see? Is it an LED? Is it an incadescent bulb? or is it a small silver or brass aperture?

Peace,
dave

You need the focusing lens or any laser will be nothing but a coherent and monochromatic flashlight.

Sounds like a Laser to me.....

yep, raw laser diodes spew highly divergent beam, smth like 10x18 degrees for typ red ones, very much like a regular led, except that they are much closer to an ideal point source (single mode emitters), much more monochromatic and coherent.

Does it look like the diode pictured here http://www.laserpointerforums.com/forums/YaBB.pl?num=1207001792

or here http://stonetek.org/shop/index.php?main_page=index&cPath=65&zenid=cecc1637a24c86413c3803140776525f

Remember that you are only going to see the end of the diode and that it is only 5.6mm in size. If it looks like one of those, it is a laser. It migh still be a sucky laser, but it is a laser

Peace,
dave

Re: Spymodex 300mw Ultra power red laser (read: LE

Guys, thank you very much for the fast responses. It's really quite possible that I made a mistake. Shame on me if it was indeed so, though -- I have a degree in economics, but I work as computer engineer... I guess I might need to drop that "engineer..." :D :-[

I made some pics, just let me see how to transfer them from the camera...

No luck, unfortunately: neither the card reader, nor the USB cable are in my bag. I should be home in about an hour, though, and will post the photos from there.

Meanwhile... The diode doesn't really look like any LED that I've ever seen. It's indeed a small brass case with tiny aperture...

Thinking of it now, I should have recalled that all CD/DVD players I had taken apart had a lens over their laser diode... Shame on me, really.

I'm going to take a leap of faith and say that you have a laser there ;)

Now to break your heart. Search "Spymodex" in this forum.

Then get a good one from someone here (Kenom, Jayrob) for less money or learn to build it yourself. You have found the right place to get either of those things done. If I didn't already have too many in the pipe, I would own Kenom's dual (red and blu-ray) Dorcy mod. That thing is just plain cool! Check it out:

Re: Spymodex 300mw Ultra power red laser (read: LE

Tens of centimeters on a building 400m away is just next to impossible for any LED, no matter how much lenses you have. ::) It's definetly a laser diode, but probably way less powerful than advertised....Spymodex....what you gonna do? ::)

Sorry about cheating with the link -- it's really done in good faith.

Yep. That's a laser. Put the lens back on, focus the spot, light a fire! Do you have laser goggles? If not, be careful. Even if it isn't 300mW (which it probably isn't) you could do yourself or another harm with it.

hey that thing actually looks like it's built pretty well have fun with your new toy, and don't blind your cat if you have one.
