This is not true.

You can increase the contrast ratio by placing it farther away from the screen (i.e. longer throw distance); but not (in most cases probably) reducing the lamp power.

Moreover, you need to be aware that, in some projectors (e.g. my AE4000), putting the lamp in eco-mode will seriously affect the color saturation and vividness of colors.  A bad idea.
