Step 4: Close the lightbulb with epoxy putty

Don't leave air inside the lightbulb.

Is hard to take all the air, I fill it with water and do the close underwater.
There is no problem putting the epoxy putty under the water.
Once I have it close, I take it out and let it dry.

Step 5: Done!

haha, cool. Where did you get epoxy putty though?

Secondly, no matter how hard you try, isn't it likely that there will be a few small air bubbles? How did you ensure that there are none?

Hello, epoxy putty get hard even under water, so I thought it was the right stuff to close the lightbulb.
