Take the cigars out and put them in a zip lock bag. Take the humidor in to a very dark room and place a flashlight in it. Turn the flashlight on and close the lid. I'm betting that it leaks light like a sieve. If the humidor is new, take it back and get something that will maintain humidity and has a seal (or walrus, your choice).

One humi pack should more than cover a 250 count, unless the sticks are bone dry or the walrus isn't working.
