    Trying to find a thing I read once about blue and white LEDs ... very interesting Popular Science article - did you know the scientists who developed the blue LED won a Nobel for it? i understood it was a big step forward but didn’t quite put together the ramifications. Peace prizes notwithstanding, the cursed things are hard on the eyes.

    So as to not totally ignore J’s OP and maybe hang the wet blanket out in the sunshine for a while ... I am so far hanging on to my Bone Machine GTX, which has I have to admit a beautiful blue LED

    Wot? Where?
    Does this mean I'm gonna have to go through all my pedals and make a list of the ones w/ blue LEDs? :eeks

    Because I can't remember. :cry:

    Well, this is a great opportunity to catalog your collection in a completely useless way. So, yes.

    I took all the blue LED pedals off of my board after I got a call from the International Space Station that they were getting blinded by blue light every time I turned my board on. :(

    I am partial to the Blindingman Corneal Etcher with visual bypass.

    They throw in a free folding white cane.

    Lovepedal EPH-3 Tape Delay. But it's blinding. Had to put several layers of blue painters tape over it just to bring it down to normal brightness.

    I'd rather have a red laser beam pointing right into my retina from a pedal, than having to look at a blue led on the board even if faint. That's why I've started to use camera flash umbrellas (!?) on the floor in front of the pedal board. From the pedalboard is 2 WHITE USB lamps that points into the reflective white area of the umbrellas and diffuses the white light. Then all pedals are "lit up" about the same with no too stark spots, and all leds, any, blue, red, green, are somewhat lesser contrast, and you can read ALL the readings on the pedals, no matter how tiny and cluttered. The audience sees nothing but one umbrella covering the pedalboard. And it's a conversation piece: People think it is for hiding what pedals I use (do you know any pedal manufacturer that puts out their lofo at the "back" of the pedals so it's visible from the front rows of audience...I don't...I know very well which pedals I've bought and doesn't need the ad /logostaring at me all of the time when looking down).

    On sunny days, this "umbrella" which is black, provides a SHADE (it doubles then as a shade maker), from the sun which means I still can read the LEDs withouth the sun blinding them all out. It is absolutely useless for sheltering from rain, or wind. Wind, it catches on and blows away together with the pedalboard.

    regarding blue light/LED at all, no matter how soft or strong...

    https://gunnar.com/do-environmentally-friendly-led-lights-cause-blindness/

    https://www.allaboutvision.com/cvs/blue-light.htm

    https://www.forbes.com/sites/fionamcmillan/2018/08/11/how-blue-light-damages-cells-in-your-eyes/

    https://en.wikipedia.org/wiki/Effects_of_blue_light_technology

    Especially the chapter about On Eye Health, regarding all blue LEDs, strong or weak. Here's a quote, quite technical detalied:

    "Concerns regarding blue LEDs are related to the difference between the photopic luminous flux and radiometric radiance. Blue LEDs, particularly those used in white LEDs, operate at around 450nm. The perception of the brightness of different frequencies of light is defined according to the CIE luminosity function. Photometry is concerned with the study of the perception of visible light. Radiometry is concerned with the measurement of energy. At the outer edges of the range of light perception, the amount of energy as light required to register as a perception increases. The peak efficiency of light perception is defined at 555nm, having a value of V(λ)=1. at 450nm, V(λ)=0.038 or to put it another way, it requires more than 26 times the radiometric energy to perceive the same luminous flux as green at 555nm. For comparison, UV-A at 380nm(V(λ)=0.000 039) requires 25 641 times the amount of radiometric energy to be perceived at the same intensity as green, three orders of magnitude greater than blue LEDs."

    "Although older adults absorb less blue light, possible eye damage from prolonged exposure may occur. The relative newness of blue light technology and its ubiquitous use in society creates questions for which there are no known answers yet."

    Trickfish bass amps, has a ban from local Airport Authorities to not be turned on in the vincinity of landing strips of large airports. It's almost like a drone thingy ban...

    Turning them on can be mistaken by aircraft pilots to be the guiding lights at the landing strip.

    Blue is so last decade now that everybody does it! I much prefer [any other color] to blue, really. Orange is a current favorite, along with pink. Diffused is even better- especially if everyone insists on using blue..

    Absolutely hate blue LEDs. Totally, utterly and completely. Horrible, blinding and - for me at least - impossible to focus on. I have severe astigmatism which makes certain blue wavelengths look blurry. White ones are just painful.

    Manufacturers, please, please stop using 'em.

    I've even heard that blue leds are the only thing apart from the China Wall, that is visible from the moon. Don't know how much truth it is at that though.

    But see below, which which which which leds of all the gear sticks out the most....? ;)

    Even the wedding photographer must've been severely annoyed! He had to pull back several f-stops to make a decent pic...

    Ok let's get back to topic. I don't even LOOK at pedals if they have blue led. There are way too many competitors around, that I don't think there's anyone who does the same pedal (exactly) without the f****** bue LEDs. Let's hear it in a couple of decades, if your seeing and vision is intact, from looking at a dark stage at those blue LEDs. Watch it, you may even start to play blue-eyed soul sooner than you think.

    Yes, no matter how good the pedal sounded, or had features, I moved on to something else if it had blue led. So no favorite pedal of mine at all with blue led. I go for the sound whenever I determining pedals. NOW, but not until now there's a "filter" or "gadget" to dampen the x-ray effect of blue leds. As shown before...

    Well, it ain't ideal but you can buy some little translucent stickers to put over 'em which makes them less blinding. Ain't tried it yet but it's on the cards.

    Which of course I subsequently sold.

    Now my vote is the almighty Butah and amazing Looking Glass.
