Long life incandescent light bulbs use a thicker filament than standard light bulbs. A thicker filament burns longer and is substantially less susceptible to power spikes (the cause of most incandescent light bulb failures). However, the thicker the filament the less light will be produced. You can expect less light output from long life incandescent bulbs compared to standard incandescents.
