Ok, here goes...

I try to be a VERY unbiased and "dont pay attention to they hype" type of person. So with all of the bad publicity i (and others) have heard regarding LASERWORLD LASERS lately, i REALLY wanted to get my hands on some of their equipment to prove that the negative publicity of LASERWORLD LASERS was unwarranted and outright wrong. Or, just some freak accidents of a few individuals who didnt know what they were talking about.

I had my chance.

and, no such luck!!!

I had 2 customers (who can chime in here if they so choose ) come to my house with 2 of their recent LASERWORLD LASERS purchases. A 3.5 WATT (model "Show 3500") (guaranteed minimum output 2.2 WATT) RGB "Pro line" White light full color system. and a 2 WATT (guarantted minimum output 1.5 Watt) 532 "Pro line" system.

First Up-
LASERWORLD LASERS SHOW 3500 RGB LASER SYSTEM

PRICE $5,500.00 USD

#1- BUILD QUALITY. "B" (RGB Projector ONLY! Green system, see below!)

Surprisingly, the units that they brought to me were built with "care" and time was spent to make things look "Professional." The Layout was well thought out. The wiring was neat, cooling was efficient. solder joints were good. terminal strips were easily accesible. Wires were easily traceable. Overall build quality was, in all honesty, quite nice. Lasers used were CNI Lasers which, other than being GROSSLY mis marked as to their power outputs, looked to be of CNI's usual high quality. Scanners look to be a ScanPro "X" K system. I may be wrong though. Perhaps Dave or Aijii could confirm or deny this?? This paragraph, unfortunately will end ANY positives regarding this LASERWORLD LASER.



#2- POWER OUTPUT. "F"

this RGB Laser system is rated as a ~3.5 WATT (Guaranteed balanced minimum output of 2.2 WATTS). This Laser STRUGGLED, and i mean STRUGGLED to hit about 600mW of White output. All lasers on. No modulation. 5 volts DIRECTLY input on each Module head. (NO software even in the loop!!!)
LASERWORLD LASERS rated outputs of Show 3500 Laser System:
RED (635) rated at 1.7 WATTS
GREEN (532) rated at 350 mW
BLUE (473) rated at 200 mW

ACTUAL OUTPUTS of LASERWORLD LASERS SHOW 3500 LASER SYSTEM:

RED (635)- 340mW

GREEN (532)- 150mW

BLUE (473)- 115mW


Combined total of 605mW White at full intensity, all lasers on full power. Again, LASER WORLD LASERS SHOW 3500 LASER SYSTEM Boasted output power from factory is 3.5 WATTS typical output. Balanced white output of ~2.2 WATTS. ACTUAL OUTPUT= 600mW!!!!!!!!!!!!!!!!!

I will take into account that the readings were taken AFTER THE OPTICS. Ok, so lets assume that LASERWORLD LASERS used the WORST possible optics known to mankind with an optical loss of ~20%.

measured outputs would be (with error correction of optics taken into account)
RED (635)- 408mW
GREEN (532)- 180mW
BLUE (473)- 138mW

TOTAL- 726mW.

Lets ALSO assume that the scanners used are the worlds WORST scanners with the worlds WORST mirror coatings on them. so, lets assume about 20% loss on EACH mirror (X and Y mirror) for a TOTAL LOSS of ~40% (which really doesnt even exist, but hey...lets play along). loss of ~290mW
726mW + (optical loss of scanners) 290mW= 1.01 WATTS.

I am STILL VEEEEEERY far away from their output quote of 3.5 WATTS or a minimum of 2.2 WATTS.

OK. Now the GREEN LASERWORLD PRO-2000G LASER SYSTEM:

PRICE- $3,500.00 USD

LASERWORLD LASERS specs this output at 2 WATTS output. Laser class= 3B. really? i thought 2 WATTS was class IV? but hey...im a dummy i guess...anyway....
50k scanning at....ready for this....60 degree angle. LOL LOL

#1- BUILD QUALITY. "D-"

quite simply, a joke. This one was NOT put together nearly as well as the RGB system. It looked as if this system was put together by a pissed off 7th grader who just lost his "guitar hero" tournament.

Here is the worst part...

It was a refurbished unit. LOL. The Laser inside was a no-name laser. i couldnt identify it at all. i am sure someone could, but i couldnt. the face of the laser module was scratched up and it even had the fu*king "service repair" sticker STILL ON THE MODULE!!! This WAS NOT sold to the customer as a "refurbished" unit!!! It was sold to the customer as a 2 WATT NEW LASER WORLD PRO-2000G Laser system.

#2. OUTPUT POWER. "F" BIG FAT FAILURE!!!

I tested this with both Pangolin Laser software AND direct 5 Volt on the input line completely bypassing the software. And I tested it in CW mode with NO modulation AT ALL.

LASERWORLD LASERS PRO-2000G 2 WATT GREEN Laser system factory specified output...
2 WATTS

Actual, real world, output power....

LOL....i think i can, i think i can, i think i can......515mW!!!!!!!!!!!!!!!!




Ok, again...i measured AFTER the optics. So I will use the same mentality as i did earlier...

20% loss on EACH scanner mirror...
515mW laser ouput+ ~40% (2 scanner mirrors) loss (NEVER in the real world...but ill humor the idiots at LASERWORLD...)
515+205mW=720mW. Here is new math for everyone here...
720mW is equal to 2,000mW LOL. same thing right???

Bottom line is this...

LASERWORLD LASERS is outright liars, thieves, cheats and pathetic individuals who call themselves laserists. I dont give a shit HOW MANY "Satisfied" customers they had in the past. The bottom line is that NOW...the company decided to become cheats and liars. The letters i have seen from the company to pissed off customers (rightfully so) just accude the customers of not knowing what they are talking about.

the companys defense is ALWAYS...point the finger ELSEWHERE. its not "our fault." its..
a bad meter, dirty optics, broken dichro, you dont know what youre talking about, you tested it on a sunday...they only work well on thursdays, the laser was having a bad day, the diode must be misaligned, you must have the wrong voltage, yadda yadda yadda...

STAY AWAY FROM LASERWORLD LASERS!!!!!!!!!!!!!!! PERIOD!!! END OF STORY!!! NO QUESTIONS ASKED!!!

That only thing I have ever liked or thought looked decent about the ProLine is the case. What do you think that is worth by itself; no scanners or optics?

[danielbriggs]

Any photos of the guts of the thrown together green? (Not that I'm going to buy one either way) - more just for shits and giggles

Perhaps they put that special coating on the mirrors, you know the one that is black coloured and absorbs 75% of the power
Somehow I think not...

[dave]

Scanners look to be a ScanPro "X" K system. I may be wrong though. Perhaps Dave or Aijii could confirm or deny this??

Nah, they arn't the same ones we sell.. TBH, I have never found the manufacturer of these ones.

[edit]Nice review BTW

[p1t8ull]

these guys SERIOUSLY need to get out of the laser business

No, they need to be forcefully removed from the laser business...

They're not all bad. My RS 600RGY which I brought to UK LEM puts out 667mw after about 5 mins (around 620 from cold) and is built like the description of Marks 1st laser, very well and extremely tidily.

I don't have any decent pics from UK LEM of it though as it was towards the back of the room and was a little under hazed as a result.

That said, it doesn't excuse the other ones they appear to sell. They should all be like that!!

[-bart-]

No, they need to be forcefully removed from the laser business...

Sad thing is, if they where selling anything else but lasers, they already would have been removed from business.

On the other hand...

I see a strong resemblance between laserworld, and the car-audio world. Both sell products that need specialised equipment to measure the output power. Not easily available to the consumer.

Laserworld are the "1000 Watts power subwoofer" sellers of the industry.
They will continue doing so, until their reputation is distroyed. Then they will just change their name.

As long as there are customers that only seem interested in:
Dynamic contrast ratio 1:10.000, Power: 1000W pmpo, 1500W vaccuum power, 3,5 W rgb laser, these companies will exist.

Nice review of a (not at all as nice) projector

One thing appears strange to me though : the case of the RGB3500 on your pictures isn't the same that showed on their website for that model (here). But rather the one used on the 1000-2500mW model.
But when you look at eBay, you find the RGB3500 (selled not directly by Laserworld), advertised with similar cases pictures as yours (here).

On Laserworld's website the specs of the RGB3500 is :
- 400mW/532nm
- 400mW/457nm
- 2400mW/650nm

On eBay, the specs of that so-called RGB3500 model are :
- 350mW/532nm
- 200mW/473nm
- 1750mW/650nm

Back on their website, the specs of the RGB1000 are :

- 125mW/532nm
- 125mW/473nm
- 650mW/650nm

These last specifications are quite well matching what you are measuring, not? So isn't your model simply a 1 Watt model sold as a 3,5 watt, sold by an unscrupulous seller ??

In all cases, you should note that these specs are all relying on the overpowered RED to boost the total power... There's really a marketing issue with Laserworld that the customer has to be aware of... (that is also in relation with the "pleasant technician" vs "arrogant boss" reported on another thread about Laserworld). 'coz 5500$ for a "normal" 3,5W RGB laser isn't at all realistic!!

One positive thing though, this last point should at least comfort all of us hobbyist, coz that's comparable to the price I put to build my own 1.1W RGB projector

You do make a valid point, $3000 or so for a turn key 1W RGB, using the above specs (CNI lasers), that seem fairly balanced, LaserWorld 50K scanners (Karl likes em right?), would be a very good deal; especially with a really nice case that it has.

The real problem is LaserWorld is selling this decent 1W system while saying it is a 3.5W. It looks like the unscrupulous seller on eBay IS LaserWorld to me, even if they are going for $1500. It IS eBay though...

...There's really a marketing issue with Laserworld that the customer has to be aware of...

Would that be the bit where they blatantly lie time and again about the specs of their product and continously rip people off?
