LED lights at first they might appear fantastic low-power bright source however when we look under the surface what lies there might actually scale welcome back guys it's going to be an unusual video that I don't usually do so if you liked it please would have come in the comment section below if you want to see more like it however recently the reason for doing this video and reason for researching LEDs is that we recently put in a blue LED light a low vision late night room and I noticed in the after about two weeks of using it so before that we just had a standard orange bulb in there that blew out but after about two weeks of using this bulb I noticed when I'd go to work in the morning I'd have like black spots in my eyes and so I started looking up on the internet you know in my eyes degrading and do have some disease and I started looking at LEDs and what I found was pretty spooked me out however before we get on to the juicy news we'll look at what it essentially an LED is essentially what a common standard LED is is it's got a blue light source that has a yellow layer of phosphor and that converts the blue light into the white artificial white light so essentially every time we look at an LED light we're essentially looking at the core a blue light and so if we look at the frequencies here we can see that red Red's the least what's the lower frequency it puts a least little the least amount of strain on your eyes as opposed to ultraviolet which is what the Sun emits a lot of ultraviolet rays but if we look here White's it's below blue so blue is kind of up there in the spectrum white sits below that so what we've got with LED lights is something that truly is something that's more intense for what it's giving us and so these articles they started researching the effects of LEDs especially blue LEDs and they found that in some cases blue light can cause stress or toxic stress to the retina especially outside of normal daylight hours and so the goal of this was not to use too much blue light and since LEDs have an element of blue light in them which we can see whether we like it or not we're actually looking at you can see here the spikes here CCFL verse LED no you don't say a little bit later but we see you LED lights they have that spike there blue light which can cause strain to our eyes so if you're wondering over the last few years why your eyesight's probably degraded more than it should then I mean your eyes degrade as you get older anyway that can't be helped but if you're wondering why your eyes have probably degraded faster than usual LEDs might be to blame I've noticed that my eyesight in the last few years hasn't been all the best but before that's been 20/20 perfect so I might do an experiment where I change back to see CFL and see how that goes for you guys maybe you'd like to be I'll be a human experiment for you hey how you like that but in the meantime we can see here that see CFLs the technology that was mainly used in computer monitors before LEDs didn't have that peak of blue light in there so they probably didn't cause as much stress as an LED would on your eyes is that something to keep in mind it's something that I found really interesting and something I thought I'd share with you guys and now in conclusion I will say that I no I'm not I'm not a man of science I do love science but I'm not a physicist I don't know all there is to know about this stuff so if you guys want to chime in the comment section below then please chime in and let me know what you guys think but I thought I'd share this information with you as I thought it was pretty kind of a little bit scary as well you know so essentially we're all upgraded to LEDs and we all think they're beautiful and amazing but the truth is they might not be as good as they seem so anyways hope you enjoyed this video if you did please give it a thumbs up if if you have any comments which I'm probably sure you do then please leave a comment the conversation below and I'll catch you guys with another tech video very soon not an unusual one like this one anyway bye
