When turning the pool lights on my Intelliglobe light turns on for 5 sec then turns off. Now, this light was working fine before I replaced the Intellibright 5g light that was previously doing the same thing. Now the new Intellibright 5g light works fine and my intelliglobe is now doing what the 5g light was doing before. The GFCI never trips. I do not think the light is bad. Shoot, now I am thinking the 5g light was also fine. Any ideas what can cause 1 light to turn on, then off after 5 sec? Thank you!
