Is an 800-lumen light bulb twice as bright as a 400-lumen one?

I understand that the light output of light bulbs is measured in lumens. If so, my question basically is whether the lumen is a linear measurement. If this is the case, then an 800-lumen bulb is twice as bright as a 400, no?
Also, what is the relationship between lumen and watt? That is, how many lumen should an LCD bulb be rated at in order to appear as bright as a 60-watt incandescent bulb?
