In-Ground Landscape Lighting and Pool Lighting: Frequently Asked Questions
This FAQ covers in-ground landscape lighting and pool lighting.

Part 1: Frequently Asked Questions
Q1: What are the main differences between in-ground landscape lights and pool lights?
A: Landscape in-ground lights are low-voltage fixtures installed in the soil, typically 12-24V, although custom high-voltage options are available, and are designed to be waterproof and dustproof. Pool lights are submersible fixtures installed in waterproof recesses in the pool wall.

Q2: Can I use the same transformer for both pool lights and landscape lights?
A: Absolutely not. This is a serious safety violation. Certain pool lights require a UL-listed transformer suitable for swimming pools and spas (compliant with NEC 680 standards). Landscape lights use standard low-voltage transformers. These two systems must be completely electrically independent.

Q3: LED vs. Halogen: Which is better?
A: Nowadays, LEDs are superior in almost every way.
For landscape lighting: LED lights last 5-7 times longer than halogen lights, consume 80% less energy, offer color-changing options, and are less likely to attract insects.
For pool lighting: LED pool lights eliminate the need for bulb replacement (which requires draining the pool), offer millions of colors, and are more energy-efficient.
