And you blind any bystanders up to 5 blocks away.
It is my understanding that this Laser does support some kind of interlock, but it is not designed for a fixed installation (where the interlock would be hooked up to a door switch).
As others have said, this really worries me. Even though it may be "cool" I would not want to buy one. If your are not wearing proper safety equipment when trying it out, you will
blind yourself (from reflections). I just hope the dumb people who order these things and blind themselves are bright enough to turn the device off before blinding first responders due to medical emergency (blindness), fire (It can set skin or paper on fire), or police (responding to complaints about the laser).
What really concerns me is how easy it would be for copycats to get similar Lasers from similar projectors. Even if I start wearing Blue-blocking (amber) goggles full-time, I am not safe. Presumably, those projectors have Red and Green Lasers of similar power.
Edit: on another site I saw people confusing the power output of this this with the output of a "1W LED." For the LED, 1W is how much power the device consumes, not how much radiance the thing puts out. I suspect the Laser probably draws at least
3.7 watts (by technical specs).
Edit: don't take my word for it:
wicked lasers wrote:Blue light hazard can cause BLINDNESS and not just color perception issues. The power of this laser is no joke, at 1W the Spyder III Pro Arctic is a Class 4 Laser. Do not allow unprotected eye exposure to diffusely scattered light from the beam terminating on a wall, the floor or other flat surface from this laser closer than 3 feet. Accidental eye exposure will definitely result in instant retina tissue damage even within just milliseconds of exposure. Direct eye contact with the beam or reflected will cause instant permanent damage and blindness. Sometimes blindness may take a day or longer for the onset. Unlike instant injury from a bright flash of a red or green laser, this effect is cumulative over 24 hours. It is also possible that such an exposure could cause retinal degeneration and even loss of vision later in life.
So, by using this against a potential mugger (closer than 3 ft), you will likely blind yourself as well from the reflected light.
Edit: I reported the mere existence of this device to the local police.
