SW LED Spectra

A super user took an emission spectra of one of the LEDs I use. Interesting data for sure!

Hmmm I seem unable to zoom in on the picture on the Android lemme app so I can't see any of the numbers on the graph. Does anyone know how to get around this?

What's "filtered"? After coming through a ZWB2 filter? or something else?

Is the ZWB3 glass.

ZWB3

Holy crap. I hadn't even heard of ZWB3 until now... :-)

What is the difference between these two plots?

The first plot shows a single peak for all modes/filters, but the second plot shows the secondary peak at 395~405nm for the same emitter and modes. What's going on here?

The second is a zoom showing the minor secondary emission spectra, so there’s light around 400 and 675. It also shows the filter attenuates the 400+ light but doesn’t help with the <400 light so much.
