This circuit will give you a LOW when light is
EDIT: corrected polarity. If you want the opposite polarity, swap the comparator inputs.
BTW, if you're not going to use more than 2 comparators, you can use a dual (LM393) instead of a quad.
Also note that the input common mode voltage range is only 0-1.8V at room temp. Over full operating temperature range, it will be 0-1.3V. So choose the value of R1 appropriately.
