Lurker in Light + Faerie Fire

[Tinalles]

Sanity check: if a Lurker in Light gets hit with Faerie Fire, does it:

A) Have no effect because the Lurker's invisibility is powered by light;

B) Work normally, outlining the Lurker without negating its invisibility (i.e. you can see where it is, but not what color its skin is, for example).

C) Something else?

This came up in a game I GM'ed last night. I picked option B, but thought I'd post here anyway to see if that makes sense.

Faerie fire causes them to not receive concealment from invisibility and they shed light as a candle.
Lurker in light requires bright light to be invisible.
If a lurker in light is in bright light and has faerie fire cast on them, they would still get the -20 to stealth checks and their invisibility would not grant them concealment. Just because they are still invisible doesn't mean there isn't a bright faerie fire outline around them. Its not like they absorb the light.

That's what I thought, but it was a weird enough edge case that a sanity check seemed warranted. Thanks.
