Since I didn’t produce the graph, I can’t speak to the relative heights of the graphs ... I find it hard to believe they are to scale, though. That red LASER should be off the chart relative to the tungsten filament. The LED spectrum they represent looks like a cool-white to me. In a warm-white spectrum the blue peak is lower than the green-yellow peak. I have seen no white LED that produces significant red, unlike the tungsten which is heavily weighted to the IR. In fact, most of the light coming off a tungsten bulb is IR; invisible to any human.
You are obviously in the trade or the engineering side.
I was in the wholesale hardware distribution business for 35 years. Sold a lot of lighting. But it was before the new options existed. I did sell sodium and mercury vapor replacement stuff. And quartz halogen lamps.
I have a commercial radio license and an Amateur Extra. But never worked in that field. I understand the theory pretty well, but optical radiation was not something I studied. Thanks for the clarification.
