Ways to Generate Sunlight?

There are two magic items that can shed sunlight: the Sun Blade and the Blade of the Rising Sun (both a hefty 50,000+ GP). The alchemist has the option of Sunlight Bombs. The Daylight spell specifically is not equivalent to sunlight (CRB, p. 264).

What other options are available to ruin a wraith or vampire's day, by reminding him that it IS day?

Shooting a giant hole through the ceiling?

Seriously, I have no other way. Sorry :/

Sunburst

(I know, the Blade of the Rising Sun spoiled this answer, but I figured it was worth calling out separately)

Put the radiant quality on armor

I'm not so sure that Sunburst will kill vampires. Sunburst harms any undead specifically harmed by bright light. Bright light is a different term than sunlight, and I don't believe that sunburst will kill a vampire, especially since its duration is instantaneous and sunlight takes 2 rounds.

Sunburst will pretty much no-sell a vampire that fails the save(and even if it does), although the 80' radius burst is ridiculous.

The Radiant quality doesn't say it counts as sunlight, and the fact that it generates a "Daylight" effect suggests that it isn't.
