If this pulsing can make them appear brighter than they are, why don't
they use it in domestic LED bulbs?

No idea. They are crap and I wouldn't have one in the house.

Have you ever seen a CREE LED? I've got a load of GU10 CREE LED spots and they're better than the 50W halogens they replaced. 6W in, 50W out, and to my eyesight they look more like 75W out, and a whiter light too. And they don't keep tripping the circuit breaker when they go, or making the fitting to hot to touch which is worrying next to a wood panelled ceiling.
