9W RGB special red beam!

[masterpj]

Well I have to say something on this. The Kvant's I saw did just a bit less than the stated power AFTER all the optics, and divergence (apart the low powered ones, the 1.6W RGB you own for example) are around 1.6 mrad full angle, so not so tight. *Very* recent high powered models may have lower divergence because of Jenlas D2.mini or Coherent greenies, but not much the older ones (more than a year).



No again, with the recent DPSS technology the divergence and overall beam quality has become quite worse than previously with gas lasers. Cheap lasers now most often have bad divergence and to be honest, that's a very great thing as these lasers are more likely to be used by djs & co who don't know anything about laser safety. But you're right, prices are becoming cheaper than ever.



You won't see any drop of color balance on my RGB projector when I use BAM, as I perfectly adjusted the color balance along the whole power curve, mostly by software. So that's not an assumption you can make without knowing more about the setup.

And well, don't take it wrong but you may tend to locate you a bit too fast in the "experienced" laserists... As well as a Kvant dealer, I believe your website is up from only a month or so, I don't think you already sold tenth of Kvant projectors to assure everyone all the Kvant models are acting like you say...
And from what I see you are a lot more into graphical creations (and you seems pretty efficient at this), rather than on the road doing multiprojector beamshows each week-end. You're very young, take it easy, don't overestimate you

Same as whitelight my 2.1 watt kvant had 2.9watts
Divergence is really good on the kvants so i'm not sure where you have been seeing those kvants.

Sbk I can clearly say rgb laserverkoop does not work with gas lasers, i'm talking purely solid state here.
Most people use solid state, gas lasers are huge.

sbk I balance my projector in software and take a lot of time on getting this right for graphics and i've been trying to push a kvant to the limit with turning down and clearly green modulates worst.
I never said i'm a completely experienced laserist, but definitely this is not safe.
I've sold some kvant projectors and all had much higher power then rated, mostly against the 2.6, 2.7 or 2.8 watt when rated at 2.1 .

Yes I'm more with graphical and stuff like that but It pisses me off when someone does shows that are from what i'm seeing clearly not safe and is providing no info what so ever to prove that his shows are save and making false claims that he's a hobbyist, on top of that dubious price naming and then suddenly changing prices and power.

I measured all powers indivually after the optics with a coherent power meter.
Green was not the highest power, blue is.
Kvant's dpss green have an IR filter.
They arent low budget projectors or something lol.

am i the only one who notice that its harder to breathe on PL?

..I don't think it's 'PL'.. maybe that 'tight collar-feeling' might be your conscience??.. ..just a guess, I'm prolly way-off..

Anyhoo... So, nothing but crickets from Mr Verkoopy?... oh well, so much for this 'SELLING' thread, I guess..

Anyone, out there, think they can best the performance-specs he listed for about $6-8K USD? Must be new, not used, and, since it's not coming to the US, doesn't need to meet FDA or EU-certs, but must still be a SAFE SYSTEM... Sorry, no-thanks to any Chijectors, and/or systems with 'DMX-AUTOLOLZ' cards that fire out full-power beams when you turn them on/off, etc..

Joost, you're still welcome to reply to the questions in Post #51 / here, or PM.. they've not told us off, just yet...

atmospfear over hear just fine for me

people are still helping people and people are still enjoying lasers

it is when one tries to make a "dishonest" dollar that things get sticky

simple.

Agreed.

@Edison, your experience May well be jaded based on the feedback you've been getting. If you took on board more of the concerns and criticisms, you may well find your experience on PL improving. And this would be true for Joost too. Both of you guys have had plenty of constructive feedback to improve your standing in this community, but neither of you have taken the feedback on board and openly acknowledged some pretty good advice (freely given to you by this community).

Seems to me the atmosphere is changing on PL.

It bothered me for a moment but not anymore.

I think if you are selling things on a constant basis, *NOT* a "I bought too many diodes for my own use and i want to recoop some money" type sales...... Name should be in blue. At first i didn't agree with dsli_jon, eventhough i consider him a friend, i did not agree. but the more and more people come here knowing little to nothing, then learn, then start trying to make a profit. See where I'm going Edison? Yes, I'm calling you out specifically.

Jon is extremely helpful and in my opin has every right to say the things he says and post the things posted. And back to the original topic.... where's joosty answer to #51?

[planters]

Jon,

You have lost me here. You don't agree with this opportunity seeking with out contributing approach by RGB. He is being criticized for unsafe practices and your persisting. Why help him? Why reward this behavior?

[dsli_jon]

..even though i consider him a friend, i did not agree.

Well, that's good, Mang! That's how we all learn from each other - expressing different viewpoints and ideas / voicing-concerns, etc.. if we were all 'the same', well.. we'd be diodes.. The good thing, is that - for the most-part - we all seem to maintain *mutual-respect* for each other, even-if, sometimes, we get a little 'heated' or - like I do.. obnoxious but, at the end of the day, if we can all 'settle the sand', or, at least 'agree to disagree', then we maintain that respect...

...when this all seems to get 'out of balance' is when we see that 'mutual-respect' sorely-lacking... when, clearly, one-side should 'own-up' / fix-something, and they just flat-out don't / won't, or, worse, get down on someone when - *they* - are the ones in the 'wrong'.. yeah, sometimes that's somewhat 'subjective' (what is 'right and wrong'..) when it's a matter of opinion, etc, but, when it's something pretty 'nuts and bolts' like these recent 'incidences' - and when, multiple, 'objective' parties start to come to the same conclusions.. well... if people *still* don't wanna 'own-up', seems to me that's about when we begin to hear that 'big whooshing-sound, coming down from the cyber-sky'..

Anyhoo, glad we can 'differ' and still maintain that 'mutual-respect'..

Why help him? Why reward this behavior?

I'm only 'pressing' him to give the opportunity to 'explain himself' from the legitimate - and sincere - Questions I posted about the rig.. but, remember, in so-doing, I'm certainly not obligating myself / Co. to purchase from him... Certainly would not happen for 'more Euros for less-watts' than-hawked, in any-case...

As-to the 'safety', well, I too, don't necessarily agree that those PJs were '9 Watts' being shot in peoples' faces, but - As-to whether I think what they were doing was safe / sane or not? - that is a whole separate thread / discussion.. IF he had / does choose to come and answer the questions, then, seeing those vids, I would also want to know more about the safety-controls on his adverted-rig... (scan-fail card? Unsafe DMX-options?, etc)

..But, I won't go 'lecturing him' on what he should / should not do in his shows / country, since, a) he's not working in our 'market', and b) he has his countrymen / others in that region to give him plenty of 'safety-spankings', if need-be.. but, we're not even to 'first base' here, so.. it's kinda moot anyway...

..now, if he were to ask me what I *think*...

Here we go again!
Who is the Site Admin?
STOP ACTING LIKE YOUR THE ADMINISTRATOR, put your suggestion about contribution in the admin pm box and that's that, but don put this comment in every subject on this forum.
AND NO ONE CAN PROOF THAT HE DID A UNSAFE SHOW, UNTIL THEN YOU HAVE TO DEAL WITH THAT BUT DON'T PUT SOMETHING IN HIS SHOES WHICH YOU COULD'T PROOF!!!
If this is what PL is going to be in the future, i'm out.
I hate people who think they can make the rules on this forum when they not own the forum and fuck's it up for all!

Have a nice time here ........

[dsli_jon]

Hey!!

Here we go again!...STOP ACTING LIKE YOUR THE ADMINISTRATOR, put your suggestion about contribution in the admin pm box and that's that, but don put this comment in every subject on this forum.

It's a free forum, he'll act as he pleases. If the actual Admin has a problem with him - or anyone - he'll deal with it, so... STOP ACTING LIKE YOU'RE THE ADMINISTRATOR.

And, fyi - *I* am the one that has been 'rallying' for all commercial members / people that wanna put a URL or sales-link in their sig-line, and / or people who don't, but, members like 'joost', constantly 'promoting', if-but subtlely, when-not directly-peddling their wares - and it's getting *REALLY* tiresome, for a forum that is *supposed* to primarily-be about LEARNING / knowledge sharing - THIS AIN'T EBAY!!!

..My proposal was: You wanna sell sell sell sell sell sell? Become Blued and support the forum - at *least* in that-way - or take a hike. That was MY suggestion. And no, 'I'm not the Admin', otherwise, this would have already been that way. But, it is his call, and I respect his philosphies and his whys and why-nots. But, Don't go yelling at planters!! - if you wanna yell at someone about that, you go ahead and yell at me.

If this is what PL is going to be in the future, i'm out

I'll be seeing the Admin in a little while - I'll put in a good word for ya.

With the atmosfear changing i mean that if someone post a thread and it,s just for showing his nice build and beamshots then instead of saying : great build nice, beamshots and giving suggestions is goes more like this: he, nice projector and all but where is the safetybutton and your scanfail?And from the looks of it your lasershow is dangerous and way above MPE level if you ask me. Now its fine that everyone is about safety these days but I still see kryoman for example performe on stage but apperently pointing the finger to anyone that showing some unsave beamshows nowadays is more important.

If someone like joost tries to sell a projector and he shows a video and you think that is not a very safe lasershow he is doing, why not sending him a private pm and giving him some pointers to improve safety?The post is a for sale thread and NOT with a title that says : Here is a video of my lasershow enjoy.

If someone sells something like a projector and he doesn,t know how to do safe shows doesn,t matter. If i sell a car and i don,t have a driving licence not a single buyer would care as long as the car is cheap and nice. Same with selling this projector as long as its nice and is doing what it should do its fine.

Dsli-jon is right its a Free forum but PL is divided in several specific catogories like for sale, groupbuy, help, and others. That means if someone post something in the for sale thread and showing here a video of it then your not free in posting what every you like. Your not the janitor who has the right of posting what ever he wants. You have to stay within the rules and this thread is about a projector and not about doing unsafe shows.

So i think we should all (including myself ) stop with this nonsense and talk about the projector instead of talking about safety.

[badger1666]

as this forum is about learning and sharing ideas for the hobby guys.
hey joost hows about you show us what that red module looks like on the inside
edison showed us his stuff in the past, and they look real nice.
i am sure in wont hurt for you to do the same ,we like pics and seeing how others
get things done, thats how i learnt to build multi diode setups from others sharing their ideas
