Your opinion please

I was taking a close look at this laser by Spacelas. Kinda worried about shipping from China, But the price is pretty good. They will upgrade the scanner from 30kpps to 40kpps for a hundred dollars. What do you guys think of it.?

You know that they are illegal in the USA right? And also, has a good chance of being seized at Customs? Not trying to scare you. just giving you a heads up.

Thanks for that info. That is something to think about. I have read on here about other members purchasing from China. I have not read any postings yet about customs seizing any ones laser projector.

Hi pat -

What do you guys think of it.?

I'm with Marc - I'd avoid it like una cucaracha.. You'll go much further either going with an 'X-Laser' system (PL Members, as-well..) or, when you're ready for a 'big gun', Marc / CT Lasers can take care of you... Although, he's recently introduced a fuller line of US-Certified Projectors, and I honestly don't know what models he has in the 'lower-power range', so.. maybe I'll just let him speak for himself..

..Point is, either buy a US-made PJ, or, as many here will encourage, 'DIY', it's a fun 'journey' / adventure and you'll learn a great-deal, along the way...you'll also end up with the pride of saying 'I built that..'

A word of 'caution', tho - if you plan on using the PJ - DIY or otherwise - for doing public / paid shows, you'll need a Show-Performance 'Variance' to legally do those performances. And yes, that's anything over 5mW. You can read all about it, in this simple, easy to digest PDF: http://www.fda.gov/downloads/Medical.../UCM119257.pdf - ..and you can check-out the 'rest of the Regs', here: http://www.photonlexicon.com/wiki/in...fety_Overviews ..but I'd suggest starting with the PDF..

..It will also clue you-in that, IF, say, you do make your own 'DIY-rig', and wish to use it 'commercially' (for paid shows, in-public / club, etc..) you'll need to get that 'Certified', and.. that's a bit of a 'bigger hill'.. ..But, in no-way, 'impossible' to climb. As-mentioned, Marc has 'climbed' it, PL-member 'blowfly' Mike, (..and his documentation is 5-Star - excellent job!..) 'allthatwhichis' Aaron, and others have, as-well...

..And yes, there are tons and tons of illegal, and sometimes (and of more-concern, imo..) unsafe PJs out there.. For example, very-often, these 'Chijectors' that have those 'AUTOLOLZ' DMX-boards, do not have proper circuit-design, and, when powering up / down - or even plugging in / removing a DMX-cable - will fire out a full-power beam, out of the aperture.. Not good, especially when you get into multi-Watt rigs, which most-are, these days.. Fyi, some eye-surgery procedures are done with as little as 250mW - that's 1/4 of One Watt. Think about it.

Anyhoo, sorry if you've already 'heard this lecture' etc, but, I'd rather commit the 'sin' of overstating something, than miss an op to 'pass it on'..

Hope this helps..

I have not read any postings yet about customs seizing any ones laser projector.

Here's 'un - just a 'quickie DB search' at FDA... you can find others..

What do you guys think of this laser from NRG? Are they legal here in the US

X-laser is your only current option for a legal and lowish price laser projector for the USA market.

No.

$5000 or below for a budget: Build, certify and variance yourself. Or X-Lasers.

$5000+ still can build and certify/variance yourself or Other LEGITIMATE U.S. based Laser companies with valid manufacturing variances.

Save up a few dollars and do things the right way.

Hi there

Seeing as you asked...

Being careful with the area into which you project, using goggles and following all appropriate laser safety protocols...

When you project a single white (all 3 lasers on full power) beam onto a distant wall, how aligned are the 3 beams when:

1. they exit the aperture (best determined using a smoke machine)
2. they hit the distant wall

I'm interested to know this given the mirror and dicro mounts do not appear to be micro-adjustable.

Do you see a red halo around the white beam in mid air, or any other colour separation? I'm interested to know this because it looks like a wide-beam red they've used.

Regardless of these things (which I'm genuinely interested to know because of what I've read about these projectors elsewhere), this looks like a great platform from which to start and it looks like you'd be able to upgrade the internals individually over time.

Could you explain about using goggles? Do you mean that I have to wear them when ever I am projecting on to a wall?
I haven't used the projector in any type of fog to see if there is a red halo around the white.

I recommend you do some reading up on laser safety if you don't already know about when/when not to use goggles. As you effectively have a dangerous weapon in your hands it would be advisable to get very familiar with laser safety standards (ideally before using it).

Just for starters...

You should be wearing the correct and appropriate strength of goggles when there is the accidental chance of being exposed to lasers of either class 3B (directly via a reflection off a finger ring, screwdriver etc) or class 4 (either directly or by looking at the diffuse reflection on the wall) where the exposure would exceed MPE. A full power static white beam from your projector would be class 4 and you could do yourself and others permanent eye damage from looking at the projected spot on the wall.

There's heaps of safety info on this site, in the wiki and on the net. And if you have any questions about what you read, you're in good company and there's loads of helpful, knowledgeable people on here that would be more than happy to help steer you in the right direction.

Out of interest, how did you get this projector into the US?

[DanG]

The only way things like this get into the US are two: someone screwed up, or fraud, typically on the shippers side - not that it really matters because the responsible party is the one who lives in the US.

Pat - look we have had a bit of history but I would be remiss if I did not echo Jon's sentiment. The laser you have likely has the faulty interlock circuit he was speaking of. PLEASE be careful with that especially since your grandkids are involved. I cannot overstate this.

Also, I am reasonably sure that you did not file an FDA-2877 http://www.fda.gov/downloads/AboutFD.../UCM080778.pdf which is a Federal crime. I am reasonably sure you didn't, because it almost surely would otherwise it would not have gotten into the country since the units cannot be FDA certified. I can't advise you further on this point other than to say that you have purchased something which is not legal import into the United States and with good reason. If you are committed to this course, please make sure you have the appropriate safety eyewear as has been mentioned and always keep the kids behind the unit. Unfiltered DPSS green has a lot of high energy invisible infrared in it that travels as a cone down the primary beam that you can see.

You have enough power in that unit to light your curtains, couch, etc. on fire, no joke. Good luck.
