I have an inground pool with 1 light. I replaced the bulb and then it was sealed tight well with all the grease, lids and rubber sealer. I had it run for over 2 weeks and then it went off again. The main power switch is also new. It turns on but kinda of at the middle of it. Is the bulb bad? I had people that replaced the bulb which lasts for years and years but mine is going down ever 2 weeks. I cannot pay $18 for every 2 weeks. Is my main outlet then the problem and if so how to fix this. I can pay anyone to come down here to fix it. Let me know if the problem is actually the light. I have the Hayward kind of light but regular and bulbs from intheswim for $15 or 20.
