A variable power adapter is required to drive a 6 V, 30 W incandescent

Similar to the 3-12 V 5 A adapter here.

An adapter providing 1.5-6 V output would be better but I haven't
found one.
 
Rather than limit the adjustment to 6 V, I think of halving the
output.  An integrated circuit in a 4 port package is conceivable.

Does the marketplace offer a solution?
Another idea?

A 6v transformer and an adjustable resistor made from an old electric
fire bar and two jubilee clips?
