really comfortable

The emission scaling functionality now is basically a superset of the old efficacy scale functionality.
The old way of setting the power drawn (Watts), and overall luminous efficacy (lm/W) was basically a convoluted way of specifying the luminous flux (lm) of the light, which is just the product of the power drawn, and the overall luminous efficacy.
With the new emission scale system, you can just set the luminous flux directly. In addition, you can also scale the emission of the light according to other measures, such as luminance, luminous intensity, and luminous emittance.
To create a 100 W incandescent bulb, using a figure of 13.8 lm/W from wikipedia ( http://en.wikipedia.org/wiki/Luminous_efficacy ), and 100 W, the luminous flux of the bulb is 100 W * 13.8 lm/W = 1380 lm.
