I know that the peak wavelength of the blue LED, varies between LEDs. This is also true with UVA, near UV, violet and green InGaN LEDs.

Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

Oh I see, you were using the clear MV bulb as a reference here

Pretty, please no more Chinese failure.

Why does every LED seem to have that space in between blue and green

The blue emission and the and rest emission is produced by two different things: The blue emission comes from a blue LED, and the green-yellow comes by a phosphor coating, that why that space exists between the two separate emission.

Ok thanks that always really confused me

Why do you think it is unforeseen? You may easily make this type of LED anywhere between about 500 down to 300-ish nm, it is just a meter of optimization (some applications and/orphosphor composition suit better shorter wavelength, some loger). But it is quite common for a cheap products to not use any exact specification, but "WhatseverIsJustTheCheapestOnTheMarketToday", so sometimes the cheapest is 438nm, week later 450nm, so obviously the production then varies (and the phosphor is then either designed as some compromise, or sourced the same way as well)...

No more selfballasted c***

The LED wavelength could be varied indefinitely according to the wish, the phosphor radiation is given just by the used doping elements and you can vary just the amount (the typical LED phosphor uses at least two components, so you may vary their ratio and then the total phosphor amount).

Quote from lights*plus on Apr 11, 2018 at 02:21 PM I knew of a small variability from one LED to another, depending on the driving current or other driving parameters. But nearly ~10 nm in the blue InGaN peak? According to the mercury lines, the phosphor looks much more consistent! Due to the size of the LED die, the variable becomes magnified which I would imaged. Same goes with the hfe (I can't seem to use the subscript code here) variable as common bipolar junction transistor. You try to put two different pairs of transistor as the Darlington transistor and another pair as well, you will get different value at the output. https://en.wikipedia.org/wiki/Bipolar_junction_transistor#h-parameter_model
