IME, you will find it dim. We noticed a real difference when we switched from 1000 lm bulbs to 1200 lm bulbs in our stalls. ( we use compact fluorescents tho)Much brighter!
Halogens usually last longer and use less electricity for the same amount of light, than ordinary incandescent floodlights. I don't know why the ones you bought are only rated 2000 hrs.
