How do spell-like abilities spells are affected when cast by a creature that has a caster level below the level the real spell requires?
E.g., Deeper Darkness (requires CL 5th+) casted by a Drow Noble with just one ranger class level (CL 1st).
You cast it at first level.
Spell-like abilities do not have a minimum caster level.
I know that part, but... how are they modified?
Doesn't it make it a lower version of the same spell?

It wont change level or anything, the only change will be things dependant on caster level such as deeper darknesses duration.
Spell-like abilities are dependent on class levels only as written in each monster entry.
In your exemple, the Drow noble, the monster entry says that
drow noble's caster level for her spell-like abilities is equal to her character level.
Because the Drow and Drow noble have no racial Hit Dices, it may be a little bit confusing.
Take the Quasit as another exemple: It has 3 hit dice, but cast each and everyone of its spell-like abilities at 6th caster level, even communion.
I hope it helps a little bit.
In regard to drows, i want to know if that could "lower" the level of darkness, so they can use it in combo with faerie fire, allowing faerie fire to bypass it.
I keep the question broader, anyway, cause the answer would shed light to more scenarios than drow tactics.
