I bought a couple of these projectors to use as satellite projectors. These were purchased from Winni at Goldenstarlaser.com
You can see the product page here.
First off I would like to say that Winni is great to work with, she replies very fast and is easy to work with.
I ordered these projectors with the optional flight case for 40$ extra each. They fit the projector perfectly, with enough room to store a DAC and some cables on top. It is well worth it in my opinion as flight cases normally cost around 200$, and they wouldn't be perfectly fitted for the projector.
One of the rubber feet on the flightcase fell off during shipping, it wasn't due to bad construction quality because the rest of the feet are on really tight, I assume DHL must have bumped it pretty hard along the way somewhere, I am working with Winni to get a replacement.
Sorry for the bad image quality my friend is on a vacation to Vegas so he needed his old DSLR back as a backup camera.
The cases were covered in tape from shipping, and it left a huge sticky mess. It's going to take me a while with googone to get it all off.
Now, onto the projector.
The specs advertised is:
200mW and 300mW 638nm 1.5mm, 1.2mrad
100mW 532nm 3mm, 2mrad
500mW 445nm 4x2mm, 2x0.5mrad
The blue and the green were as advertised, each projector was producing 85mW of green and 470mW of blue. Taking into account the optics loss, I would say that is on spec.
The red is a whole different story though. Instead of two modules it was just one and the beam was NOT 1.5mm, 1.2mrad. It was a single module with a multimode mitsubishi diode, and no correction. The beam is massive and rectangular. The power wasn't even up to spec, it metered at 370mW on one projector, and 400mW on the other. I'm not upset about the power though, as the white balance is already pink enough with that much red, but I would have liked to know the real beam size before ordering. It's not a huge deal since I am using these for beams only, but it is disappointing compared to what was advertised.
Edit: Divergence is 3.5*1.3mrad and beam size is 4.5*3mm at aperture.
The construction of the projectors is okay, the modules are mounted onto thin plates that prop them up to the height of the optics mounts. I don't think it will be a problem, but if they heat up and expand it could throw off the alignment. The optic mounts are okay as well, they are not adjustable and are essentially just holders. This will be a paint in the a** if the projector ever needs realignment, but they are bolted down really tight and are glued down. If they can survive the bumpy trip from China and still stay aligned I am confident that they will last a while. If I ever have to re-algin them though I may as well throw them out and buy 3-aixis mounts.
The built in features on this projector are actually neat and useful. The projector has a built in LCD screen on the back for easy operation. The sound mode works really well, the beams match up really well with the music, a lot better than what I have seen with the REKE. The projector also feature a SD card mode, you can load .ild files on the card (Winni included a 1gb card for each projector) and you can select the frames with the LCD display panel. It also has DMX which I have not tried, and an auto mode with pre-programmed frames. You can also select the scan size and scan speed in the menu. ILDA control works quite well, and the scan angle is unaffected despite going through a show card (this was a problem with the REKE)
As for price, I paid 325$ each for these with PT-20's (PT's are not as good compared to DT's) then 40$ each for the flight cases, 7$/kg for shipping which came out to 70$ each, 4% paypal fee's which was around 35$, then 85$ each at the door for tax
+ 10$ DHL brokerage fee. Even though they were marked as 30$ each, customs decided that they were worth about 500$ each. DHL only charged 10$ for brokerage, so I am very happy with that; most other couriers would charge an insane amount for brokerage. In total the pair of these cost me around 1150$ Canadian. I was aiming to pay only 500$ each, so I went a bit over budget.
