Review - NRG 1000mw RGV 40k Laser Projector
This is a prototype projector
since i received this projector the following has been changed in future models -
- full analogue modulation
- CNI 404nm
Ill start with the spec –
Price £1199
40k scanners, not sure of the make
35000 points/second 20 deg
40000 points/second 15 deg
50000 points/second 8 deg
60000 points/second 5 deg
Lasers –
150mw 532nm CNI, TTL modulation
500mw 650nm CNI, TTL modulation
2x 150mw 405nm unknown make TTL modulation
Ill start with the outside, working inside and then last the output.
Safety! As with the previous NRG projector I reviewed this projector comes with a key switch, Scanfail signal detector and interlock. The key cannot be removed from the lock in the on position
NRG sell an emergency stop switch with a long cable, the key cannot be removed from the key switch in the on position. The emergency stop is an extra and does not come as part of the standard package.
The outside –
The case is very well built and extremely solid, it also has some weight to it, I love the bars (handles) on either side, it makes carrying the laser very easy. The case has an adjustable bar/bracket for hanging the laser, one thing I didn’t like about the bar is the small allen key screws to lock it into place. I can imagine this being very difficult when holding it up high trying to attaching it to a trust. The allen key screws should be replaced with butterfly ones that can be done up by hand.
the laser arrived in a nice padded flight case
Inside –
As with most “off the shelf” projectors there is some glue inside preventing things from moving, make of this what you will. The inside is pretty tight with little room to spare, one thing I did pick up on is the lack of dust filters on the two fans blowing air into the projector. I will mention this to NRG
The output –
When I first got the projector and turned it on I was looking on the wall at the beam to try see how many lasers were inside and I thought there was only one 405nm. But turns out there’s actually two they are just aligned perfectly and haven’t moved whatsoever even after being posted.
The green produces an excellent beam, although the red produces a nice beam its very big as expected with most red modules and the 405nm produces a nice small beam although very dark.
The red – the module is a CNI so that means its very well made and will last long but the beam is very big and not good for projecting images. So it’s a kind of 50/50 really. On the previous NRG projector I reviewed it had dual diodes which produced a very tight beam.
The 405nm – they produce a excellent tight beam and are aligned perfectly but they are to under powered for the red and green. I understand that using 405 brings the cost right down of the projector but personally I feel a 473nm is needed in this projector. It should be noted that NRG are happy to upgrade to a 473nm at the request of a customer.
All the lasers are TTL modulation which is a shame as this limits the projectors to 7 colours. Due to the limited time I had this projector I was unable to test the power output of each laser but as two of them are CNI I have no doubt they are producing the stated powers.
NRG clearly state what is being purchased when buying this projector so people know the colour of each laser and the modulation type.
The projector does have a built in DMX but its aimed at people who have a DAC to get the full potential out the projector.
As you can see from the below pics I really struggled to pick the 405 up, in real life it does look a bit brighter.
it doesn’t show up well on camera but this projector does make an amazing pink colour
The scanners – I was generally impressed with the scanners they produced a pretty good ilda test pattern as shown below. The scanners are rated at 40k, but can be run higher if the scan angle is brought down. The scanners coped very well with all the animations I played, I was using Pangolin quickshow. The below videos show the scanners running at 30k only and in real life there is very very little flicker.

Conclusion –
This isn’t a bad projector and I wouldn’t be disappointed if a brought it, but there is room for improvement. Very solid case, very good scanners and quality CNI modules, but not the best beam output.
