Harmony 2 - blue light detected

My Bell 2 is black, so I’d just very carefully cut slightly larger to be sure no light leakage at the edge and chances are the cut edge wouldn’t be very visible.

Would be great to test to see which gives the healthiest result in terms of nm light wavelengths after the film is put on!

Thanks @jordan

No problem! They have a peach colored one listed but I think I’ll email them and ask about the orange one. There are also gel light filter overlays but I couldn’t find any that are sticky backed like the irlen ones

Thank you, Jordan, for the light spectrum graphs, they’re really helpful to me.

I’d love to see red lights with no blue light at all be the standard for e-ink devices. I looked into having a local tech company change the “warm white” lights for red ones, but they said it wasn’t feasible.

Even a little short wavelength blue light hurts me because of my medical condition.

I’d like to have a kompackt. I’d like to have a harmony. I’m going to wait until red light is the standard.

No problem! glad I could help.

Technically someone who can do surface mount soldering work could probably swap the leds out just is very hard as they’re tiny tiny. Normal electronic repair people wont be capable. The question is whether or not the LEDs are easy to get to or if they’re hidden in the eink panel assembly. Its front lit so im not really sure where they are placed.
I will post the color spectrum data of the mudita kompakt when I receive mine. I also am going to test the bigme hibreak pro eink and the minimal phone which also is eink. Orange LEDs could be enough for you too. I think the issue with the harmony 2 is that mudita is blending white and orange leds to get a light orange appearance. For example if you look at the daylight dc1 tablet after a certain brightness level itll disable white leds and only keep the orange leds on for zero blue light. Sorry to hear about your condition I also have similar issues.

I have white 1 and black 2 but no measure equipment
Eye wise I cant tell the diff by looking

Orange LEDs would be great, too.

I learned that talking about light in terms of nanometers and scotopic photopic ratio is more accurate than talking about light in terms of color temperature, when I was trying to understand my light sensitivity…
In that wonderful spectrum graph you shared (thank you again), the photo on the right, at light intensity 1, has a less saturated blue region, which would be expected at lower light intensity, but the same ratios of light.
I acknowledge the loss of the spectrum that comes with the energy benefits of LEDs.
Instead of converting 450 nm with phosphor, either choose spectrum joy at 480 nm, nostalgia at 589 nm, or stargazer at 670 nm or whatever astronomers and people who need their night vision like.

@jordan I am really interested how you’ve set yourself up to avoid all circadian disrupting light.

I started reading on this topic years ago, and it seems to me that it takes quite a bit of work to really do it. I looked up the Dasung 13.3" e-ink monitor you mentioned, as well as your UPRTech Premium spectrometer. Very interesting, thoughtful technology. I had seen what Fiara, Ocushield, BlockBlueLight.com, TrueDark.com and others offered before, and noticed Hoogalight mentioned on this forum. I had not seen a spectrometer in use or the Dasung e-ink monitor. I invested in EMF meters, which has been very revealing, just as your spectrometer is. A spectrometer is a bit pricey for me right now.

I asked a local Irlen diagnostician if anyone in the Irlen networks has used a spectrometer with the Irlen coloured acetate optical grade films. She said she will ask. Irlen seems oriented to daylight situations in the main, but there is an overlap in ‘territory’ with blue light blocking given they deal withscreen use and lighting.

I also asked Redgrass Creative about their R9 full spectrum RGO blue light, flidker free desk lighting for spectrometer information as this was mentioned on their KidkStarter campaign but without the image for all to read.

Body-friendly technology is worth finding, but finding it isn’t easy. Of course, as always, up to you what you want to share.

I’d like to know where the lights are in the Mudita Harmony 2 clocks, if someone who works for Mudita would like to respond back! I’m very curious.

Of course, I know Mudita would never suggest switching lights out yourself, but I mean, would that be the only way other than stick on paper?

I try to at least limit it as much as I could. I know with cars for example its hard to eliminate that lighting unless you buy a older car. In my house I have switched all my lighting to incandescent light, avoiding all LED light. I also avoid even orange LED bulbs for indoor lighting since it lacks a wide spectrum including IR. For alarm clocks I think its totally fine being orange LED. I just use incandescent lighting indoors since I can get red light and IR light which is beneficial to our bodies. I have seen LED bulbs that are capable of red/ir but I just am not a fan of LED lighting in my living space when filament bulbs are an option, much higher quality light.
The dasung 13.3 monitor is one of my favorite devices. In lower lighting conditions I have a vintage incandescent book lamp that works decently to light it up. I just am needing a eink phone in my hands and ill be set! lol.

I have seen ocushield and the others but all of them claim the screen looks normal but blocks blue light which isnt really true. If its not amber/red than its still allowing disrupting light through. I thought of buying an ocushield just to test with my spectrometer and throw on youtube so people have transparency. I actually did test the dasung and posted it on reddit awhile back. It does have a orange front light with a much smaller blue light spike. I just avoid LED as much as I can so I dont ever use the front light. For the kompakt for example Ill use the front light on certain occasions when I dont have good lighting. Emf meters are cool and are helpful, especially RF meters too and dirty electricity meters which I recently purchased.

I emailed irlen institute and seems they sadly dont sell their orange cling ons (adhesive back) but I think they said the overlay is available. I have actually tested irlen sheets and my irlen glasses but I only have blue and purple. Curious if the orange / rose overlays block blue light as they could be useful as I mentioned with the clock.

Speaking of desk lighting I know that my friend uses a lamp I believe is called “chroma” its pricey if I remember correctly but I know its blue light free. He uses it to light up his Eazeye 2.0 RLCD (no back/front lit monitor)

btw heres a pic of my dasung 13.3

I think its somewhere integrated on the Eink panel, I just dont know how hard that is to get to since it might be under the screen where you cant separate the layers without it getting destroyed.
