It’s not conclusive, as LEDs exist in all forms and in all outputs, it’s hard to draw a definitive answer if they all fall into the same category of let’s say very high level or extreme level or even low or mid, does it correlate with the power draw or it’s inherited (the min level of radiation each watt makes)… so many questions…
But they all emitt high levels from the get go, that we know according to infinite people who checked them with meters, it’s all over the interwebs.
When we say high levels we compare it to HIDs, CFL, etc
We can go deeper and show the larger scales and graphs of radiation and each segment and it’s appropriate connection to the harm it makes
Science claims it has no effect whatsoever, in reality we can see it’s clearly not the case.
