Light bulbs do not last forever. However, call a qualified pool service tech to trouble shoot the system since you do not want to mess with water and electricity. There are certain things he will be looking for and testing for and you do not have those qualifications or tools. Turn off the power to the light until it is serviced. Let the tech turn the power back on after he is finished.
If you are referring to a commercial pool you would have to check with your local pool inspector. The rule of thumb for commercial pools is: is you have a light in the pool it needs to work. If you don't have a light you are likely grandfathered in without a light.
That would depend on the type of light, the wattage, the shape of the pool and the size of the pool.
Lightning
yes you can but with water and electric you should have someone that is insured do the switch it would be much safer
We had a problem,year after year with every bulb we had replaced. My pool contractor would check the electrical current in the switch, in the connections under the plate in the deck, and in the fuse box. He would also check for a current in the bulb everytime. No problem would show up each time but the bulb would never stay lit for more than 30 seconds everytime it was replaced. It took me five years to get him to remove the light and low and behold, the contacts were rusted. Hope this helps. Lori
A bad or old light cord. Water or moisture getting into the light can. I hope you have a GFCI on the system. Call a professional pool tech to troubleshoot and advise. A replacement may be in order.
It is not the salt water pool or the salt water that is turning your hair green. It is a poorly maintained pool with a chemical imbalance - pH and total alkalinity out of required parameters.
Yes, lightning can damage a pool light.
I would seriously consider turning it on at 0 degrees Celsius.
The housing ring, depending on brand, will hold the gasket. Some lights are assembled with a housing ring and screws others have a clamp type ring. There are several types manufactured. Remember to always replace the gasket with a new one when replacing the bulb etc. Ken
Algae will develop in untreated water turning the water green and or foggy. If it is a swimming pool, and you don't mind, it can be treated with chemicals that you can get at the big box hardware stores or a pool supply place. If the pool is for fish you can use a biological filter and pump system.
Pool lightCall the company or person that leased you the property and ask them where the switch is to the pool light. If they don't know; often a pool light is turned on by a breaker in the panel marked "pool light." A breaker is an overcurrent protective device, it can not be used to "switch" a light unless it is marked "SWD".
