[/COLOR]Look at how many of those are firearm/defense related. Think there's a coincidence this is now coming out of the executive branch??
That's exactly what came to mind when I went through the list...

If you can't get your way by going through the proper legislative channels, just take the 'backdoor' approach, through regulatory agencies, or issue some executive orders...

I wonder how many people realize that cops are shooting them in the face with non-visible laser beams.

Forgive me if i missed it, but from what read its not going to affect our community. and they did mention gun lasers? lasers used for leveling, HuH so the construction guys at my house that were using a laser level to level the ground and the surface area of where my pool is going to be will be illegal?
It sounds like there going after anything that puts out a visual laser.. again did i miss something in reading the article?
Well, there's this in the proposal:

Note: 21 CFR 1040.11(b) establishes an upper class limit for all SLA laser products as Class IIIa, which has an accessible emission limit of 5 milliwatts. *

And the footnote for that is:

This means that SLA lasers that emit invisible radiation (wavelengths up to and including 400 nanometers and wavelengths higher than 710 nanometers) may not exceed the accessible emission limits for Class I, because Classes IIa, II and IIIa do not include wavelengths outside the visible range.

And that invisible radiation higher than 710nm makes me wonder if this could be applied to parking sensors. But I'll be honest and say I have a hard time understanding that proposal and what it's talking about.

Well they didn't technically ban vitamin B6, at least not all forms of it. I believe they banned Pyridoxamine.
It must be competing with some petro-chemical from big Pharma.:)

Yes it was(treatment for diabetes) just like red rice yeast. The FDA is the enforcer for big pharm

Not trying to be a smart ass but pyridoxamine is the only active b6. Thus any other form is not effective.

On a side note, we don't NEED lasers for laser jammers, their power density do make them more effective than some other light sources used in the past.

x2 would be funny if the market went backwards

I think the new regulations are to address "safety" issues (so people don't have permanent eye damage). The LI's are Class 1 lasers so they are generally safe to look at even for extended periods of time. Even Class 3a lasers are generally safe <5mW (when not looking through optics). So if the LI were truly 115W I think when a LEO shot at you with his LIDAR gun your LI's would probably be igniting the cars in front of you as well as the LEO and his cruiser. :)

This is a 100w laser:

The LI is 115 watts, but only in pulsed mode and not continuously firing. I don't know how many mw the diode would be good for if it were to lase continuously, but it would be significantly less. However, the semiconductor is able to withstand a high power pulse of extremely short duration, and when these pulses are strung together with a PWM controller, we get a brighter output than if the diode were run in continuous mode. See http://en.wikipedia.org/wiki/Laser#Continuous_wave_operation for info.

This is a similar diode to what all jammer manufacturers use:
