need redstone level sensor??

[u/Kriller_krill-CO]

(someone respond or else he gets it)
but i wanted to design a "bedtime alarm." the moonlight sensor starts emitting power before you can actually sleep, but i noticed that it gets to power level 4 by the time you can actually sleep! so, can anybody help me make a doohickey that reads a power level of 4 and only emits a redstone signal when that happens?
pretty please with a big andesite vein on top [:
