The price is another problem with LED lighting. In addition to being more expensive up front, LED lighting needs special transformers and converters to use the right voltage, which is between 12 and 32 volts. This will need more electronic equipment, which will add to the cost of the whole thing. The good news is that these transformers aren’t too expensive and usually work well.

Just like halogen fittings, LED lighting can sometimes leak as well. Luckily, the refined resin-filled LED light fixtures solve this problem for the most part. If you do need to replace a broken LED fitting or a pool light that has leaked, you can switch to the resin-filled LED version.
