Noopysche hurting eyes

[bristleworm]

Anybody running the noopysche pro iv notice it hurts the eyes?
My eyes definitely feel "tired" after looking at the tank and both my wife and son say it bothers their eyes.

I would guess it's the glare from the fixture. Can you post a pic of the tank that also shows the light fixture?

Do you have with a diffuser? This way the light is completely enclosed with no glare at all.

Maybe looking at the tank instead of the light is the problem. LED lights are not meant to be looked at directly for any length of time.

How high is the light because it maybe overlapping the tank duento height position? I have mine 9" from the water surface and it has perfect spread.

Light is about 12" above the tank.
Not looking into to the light, actually looking at the critters.

You have a different shade to me and I also have the diffuser which I can't see on yours.

I don't have that problem.

This is the best pic I have on my phone

Yes, the shade is a 3d printed one. I do not have the diffuser. Do you get it off the noopysche website ?

Do any other led type lights bother you? Asking as some people are very sensitive to the (what I used to call subliminal) flickering. Most don’t notice, but for those that do they can be bothersome and even cause headaches. I myself am not affected by the flickering and never noticed it.

Another thing that can be bothersome with some reef leds (especially if coming from flat lighting like t5) is the disco ball effect triggered by ripples. That and light spill into the room. Both of which are quite bothersome to me.

Lowering the mounting height can reduce light spill…but will reduce spread.

One thing that really bothered me with led pucks was the reflected light ripples that bounced all over as I have a rimless tank. I ended up getting a 1.5 (maybe 2) inch, roll of matte black vinyl wrap. I stuck that around the outer, upper tank edge so that it covers the dry space from just below the waterline to the edge. This eliminated all the, in my face, reflected light ripples.

Don’t know that any of this would apply to your situation but figured I’d throw it out there.

No the duplexing(flickering of the led's) normally doesn't bother me. Might be the lack of the diffuser as mentioned above. It's interesting that my wife and son also complain about it.

I'm at a crossroads. It deters from our viewing pleasure so I bought an AI Prime HD.
My son has one and it doesn't bother my eyes. The K7 is doing really well with my corals- do I throw money at it and try the diffuser- or just throw in the towel and go with the Prime?
The Prime has the advantages of a much better app and bluetooth connection; that is swaying me as well.

I’ve run diffusers, years ago on some Kessil ap700 fixtures. All they did was mute the sparkle/shimmer (noticeably, but not drastically) and reduce the lighting output. I had to run them 100% (as opposed to 80%) with the diffusers. I’m not sure that they’ll be of any benefit in your situation if the flicker or shimmer doesn’t bother you to begin with.

kind of feel the same way. Well, the AI is on the way so I'll switch it out and see what I get. I'll hang on to to K7 for awhile in case I need to switch back for my corals.

Is it possible to turn down the blues and up the white? If not I don't see the IV being and improvement to the III. I ran six k7 pro III for several years and they were great.

PS. When I set up lights I always set them so they are pleasing to me then adjust intensity as needed depending on the coral being kept.

It might be my color mix. It might be the color banding that flickers off the substrate.

It very well may be the PWM frequency that you are subconsciously seeing. It may also be the color of the light you have dialed in and even the sounds the system is making combing to cause fatigue.

It will be interesting to see if the fatigue goes away when the new fixture is installed.

Maybe allergic to the PWM! LOL.. My son has the AI Prime and I watch his tank with no issue. Might be the lens on the AI that helps?
I'll keep everyone posted!

 

[bristleworm]

Well this is interesting notice the light on the back wall. I can't see this with my naked eyes.

I don’t think it comes down to a lens or not, but who knows. My guess is the PWM profile, but it is just a guess. I believe that I am sensitive to it from some sources. I didn’t run the NS long enough to notice but I do remember the light having an odd quality to it.

I think the new GHL fixture is constant current instead of PWM and that is a huge improvement if you ask me. I have always wondered if the PWM bothers the fish.

 

[bristleworm]

Watch the video above. Its unnoticeable just looking at the walls.
Ive never seen a random PWM if that's what it is. Im leaning towards a bad driver for the blue or violet LEDs???

 

[BeanAnimal]

It could be the fixture or it could be the camera’s sensor reacting to the PWM and not being able to settle on exposure or white balance.
