/diy/ - Do It Yourself

>>1618045
The battery goes right underneath the circuit board like this, then that smaller diffuser screws over the top, then the big sphere goes over the whole thing and is water sealed at the bottom, so the whole thing is tightly enclosed with zero airflow - I think you're right about heat being the cause.
I can't really move the battery because it would block the light in any other position, perhaps drilling some airflow holes in the bottom of the plastic base would be a good idea?
