Michael is right on the ball.
My first question is "what RH was the humi before you got the new beads and hygrometer?"
Beads will not bring down a humidor's RH overnight. Give it a month with the beads dried out and then assess the situation. It can take a lot more than a month, btw.
Part 2 is "Check that thing for leakage". There are a million ways to check it accurately and scientifically, all far better than the flashlight test or whoosh test. The whoosh test means nothing, but the flashlight test is a good starting point.
To test your humi for leaks, I'd use damprid.
Put damprid in the humi. Put the whole deal in a clear bag.
Place a hygrometer outside the humidor in the bag.
Make sure your humidor is closed tight, record the reading on your hygro an hour after you've sealed the bag tightly.
Wait 24 hours and see if the hygrometer reading drops. Record the reading.
Then wait another day. Record the reading.
Wait a total of a week, record the reading.
If the hygrometer reading in the bag drops at all, your humidor leaks like a sieve.
Take the humidor out of the bag, seal up the damprid, leave your hygrometer in the bag, throw the humidor away, add your beads and cigars, and now you're in business.
If your humidor fails this test, there are many, many ways to make it airtight.
I'm not gonna get into that, but someone will, I'm sure.
