Do low energy bulbs trouble her in the same way? The reason I ask is that ordinary mains-driven fluorescent tubes flicker 100 times per second (120 in America), fast enough not to be visible but still discomforting to the few who unfortunately are sensitive to it. Compact fluorescents on the other hand flicker several thousand times a second, if at all, so shouldn't have the same effect.

I shall stock up with tungsten filament bulbs myself though, as my home is copiously equipped with dimmer switches, and present-day low energy bulbs aren't compatible with them. My lounge is also lit by a set of rather fancy globes, which look at their best with clear rather than frosted bulbs.
