The linear bulbs cover a larger area so he doesn't have to sit in one small spot to get uvb. He can roam in his enclosure toward the top (where they usually like to hang out unless it's too warm.) And still be absorbing the uvb rays he needs. The compact bulbs are not an efficient source.
Is this what you mean by not efficient? The only difference I'm reading is that the linear bulbs provide more area.
