moisture/condensation + lights = bad.
If the light flickers, the bulb is not broken. Its probably just a short circuit or a loose connection. I have some issues with my coralife, some days the bulb wont go on, and I have to take it out and re attach it. Dont know bout JBJ, but try turning it on and off, take out power chord, remove bulb and put it back in, etc.
You're in my heart, you're in my soul, you'll be my breath should I grow old
