Yes, the 130 volts you read on the bulb is the maximum it will handle. It will work perfectly on a 120 volt circuit and will actually last longer than a standard 120 volt bulb.
Quite so. The water in a swimming pool is cooler than body temperature (unless the swimming pool is actually a hot tub) and therefore, a person in that pool will lose heat by conduction.
same as the bottom
You can fill a standard in-ground swimming pool.
It is an illusion that water causes.
viscous drag- the same as swimming or diving into a pool.
As an ordinary light bulb will illuminate the whole pool, not just a circle you must be thinking of a spotlight bulb. The answer will depend on how tightly focused the spotlight is.
Hire a pool tech to trouble shoot the device. You are either using the wrong bulbs or the light fixture and wireing are old. You also HAVE to have a GFCI added to the system.
You can purchase a swimming pool light online from the Pool Supply World website. Alternatively, you can also purchase these lights from retailers such as Amazon.
Subject to the light unit at the right height in the wall, so it can be serviced from the pool deck. It takes about an hour to change the bulb £48-54 plus the bulb £39 for 300w Certikin or £39 for halogen.
That would depend on the type of light, the wattage, the shape of the pool and the size of the pool.
You probably need to replace the light switch
'Swimming Pool', sometimes shortened to 'Pool'.
Have a professional do it. As an insurance adjuster I had a death claim when the apartment maintenance man "fixed" the pool light and a young girl was killed by electric shock from improper wiring of the pool light.
Do you have a pool light niche already installed in the pool? If not, you need a pool builder to do the job to code.
it depends on which swimming pool
What are swimming pool "Coopers"
This is not a job for a novice. Call a qualified swimming pool tech to trouble shoot your pool light circuitry. It may just be the bulb but age of the light fixture, cord and housing could be a factor also. It may also be just the circuit breaker but unless everything is tested you are just guessing. You are taking a chance, even with low voltage, on stray electricity to the pool. Don't delay getting professional help. k
