WL Nano (100mW Red)

Hey guys,
I'm pretty new to these forums, and I couldn't find any nano reviews; so I decided to make one. The images are at the bottom, but you can also see them at http://imgur.com/C54tqZ5,8vqTegK,5CjNRNt,BTPH9DD,EHcYgpO,HeJYwgi.

The delivery was pretty good... Although it took awhile to get here from China. It was in a bubble-wrapped package that looked like it was beaten up a bit during shipping, but the laser was in great condition.

I don't have a picture of the packaging, though, as I threw it out after I opened it.

The laser is EXTREMELY bright, and I sent it out to get tested with a LPM: It had a power of 95mW peak, and was stable at 90mW or above (thanks to InfinitusEquitas!).

It's advertised as 100mW, so while a little underspec, it's not too bad.

It has an FDA complaint endcap (picture in the album), which is really nice: You can unscrew it off of the battery screw, and it seems really easy to connect.

I'm not really sure what else to write, so if you have any questions, feel free to ask! I just bought a cheap LPM, so I can measure it again (once it comes here). EDIT: My HLPM II tests it as 160mW, but I think that's a bit high.

Also, feel free to click on the rep button! I've been on some other forums (bitcointalk.org) for years, but I'm new to this one. If reputation means as much on here as it does on there, I probably need some!

Thanks for reading!

Hah, didn't notice it. Fixed!

Great :beer:

This laser is very cool. I personally like more the 405@75mW version. +1 from me

Thanks! I just broke the wiring in the endcap (not their fault, completely mine)... so no more FDA compliance for me!

What do you like about the 75mW version? I just got the 100mW because it was the highest power.

in spite of what the chinese seller told you, this pointer was never FDA compliant.

there is no such thing as an FDA compliant end cap.

FDA compliancy requires a key switch, safety interlock, activation light, aperture shutter, and activation delay, if I recall correctly. No such FDA compliant endcap truly exists, although it may have the safety interlock within FDA specs

that's for lab lasers only.

a laser pointer cannot be >5mW and be FDA compliant. regardless of what the vendor website claims.

Oh, they said it was an "FDA compliant endcap".

No it just cannot be advertised as a laser pointer. A handheld laser featuring those five points will be FDA compliant

assuming it's not promoted as a laser pointer (although it clearly is a laser pointer), "demonstration" lasers still need to be <5mW or have a legal variance and product report to be compliant.

go ask the vendor for their FDA paperwork...

i'm not trying to be a buzzkill. as long as folks are being responsible with their hot pointers, i really don't care. i do think it's important to point out that you should be cautious about using them with impunity because you think they're legal.

Laser Light Shows

“Demonstration laser product means a laser product manufactured, designed, intended, or promoted for purposes of demonstration, entertainment, advertising display, or artistic composition.”

Lasers promoted for entertainment purposes or amusement also meet FDA’s definition for “demonstration laser products.”

Laser products promoted for demonstration purposes are limited to hazard Class IIIa by FDA regulation 21 CFR 1040.11(c). This means that pointers are limited to 5 milliwatts output power in the visible wavelength range from 400 to 710 nanometers. There are also limits for any invisible wavelengths and for short pulses. Laser light show projectors therefore may not exceed the accessible emission limits of CDRH Class IIIa. Laser light show manufacturers must submit a variance request for FDA approval in order to sell and operate higher class (Class IIIb and IV) laser light show equipment.

Prior to using Class IIIb and IV lasers for a laser light show in the United States, the following documents must be submitted to the FDA:

Product Report describing the laser projector,
Laser Light Show Report describing the laser light show, and
Application requesting FDA approval for a variance from the demonstration laser product hazard class limit of IIIa (5mW visible output).
These submissions must be prepared with either the CeSub electronic submissions software or the paper reporting guides listed below.

If you are purchasing a certified laser projector for which a product report has already been submitted, you need only submit the laser light show report and variance application.

Your firm can begin to produce laser light shows only after receipt of a variance approval letter from FDA indicating the conditions under which you may produce the laser light show or distribute laser light show projectors.

What about alignment lasers?
