Thanks for the graph. If it is accurate as to emission level, looks like LED lamps produce roughly 1/2 the emission of an incandescent lamp. And that the emission of the LED lamp has a pronounced spike of intensity and rest of the spectrum is 1/2 that spike level.
That uneven emission spectrum might explain why it sucks to read by.
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.
