75W Landscape Transformer - Low Voltage Multi-Tap (12V-15V)

The Lightkiwi 75W Low Voltage Transformer is the perfect entry-level solution for small landscape lighting systems — a handful of path lights, a few spotlights, or accent lighting for a compact garden or front yard. Unlike the 150W, 300W, and 600W models, the 75W comes with a built-in mechanical timer, so you can automate your lighting schedule right out of the box without purchasing a separate timer. Heavy-duty stainless steel construction and a weatherproof enclosure ensure years of reliable outdoor performance.

## Why Multi-Tap Voltage Matters

Voltage drops as electricity travels through wire — a fixture 80ft away receives less power than one 10ft away, causing uneven brightness. The 75W transformer offers 12V and 15V taps. Connect closer fixtures to the 12V tap and longer runs to the 15V tap to compensate for the drop and keep all lights at consistent brightness.

## How Many Fixtures Can a 75W Transformer Power?

Stay within 80% of rated capacity — that's 60W of usable power.
Most Lightkiwi LED landscape fixtures run between 3W and 20W:

- 3W path lights → up to 20 fixtures
- 5W spotlights → up to 12 fixtures
- 20W floodlights → up to 3 fixtures
- Mixed system → add up your total fixture wattage and stay under 60W

The 75W is ideal for smaller systems — a typical front entry, a compact garden, or a single lighting zone. If you need more than 8–10 fixtures or plan to expand, consider the 150W for extra headroom.

## Frequently Asked Questions

### Does this transformer include a timer?
Yes — unlike the 150W, 300W, and 600W models, the 75W has a built-in mechanical timer. Set the dial to your desired on/off schedule and it runs automatically every day. No separate timer purchase needed.

### Can I add a photocell?
Yes. The transformer has a dedicated photocell port. Add the Lightkiwi L6709 Photocell at checkout or purchase separately to enable automatic dusk-to-dawn operation alongside the built-in timer.

### Can I add a separate digital timer or WiFi Smart Plug?
No. Because the 75W has a built-in mechanical timer, the timer port is already occupied. The Digital Timer and WiFi Smart Plug are not compatible with this model. If you need digital scheduling or app control, choose the 150W, 300W, or 600W transformer instead.

### What wire gauge should I use with a 75W transformer?
14/2 gauge wire works well for most 75W installations. The terminal block accepts only one wire per tap (vs. multiple wires per tap on larger models), so plan your wire runs accordingly.

### Is this transformer weatherproof?
Yes. The stainless steel enclosure is rated for outdoor installation. Mount it on an exterior wall near an outdoor GFCI outlet.

### What is the difference between the 75W and 150W transformer?
The 75W has a built-in mechanical timer and supports up to 60W of fixtures. The 150W has no built-in timer (timer sold separately) but supports up to 120W and accepts multiple wire runs per terminal. Choose the 75W for small, simple systems. Choose the 150W if you need more capacity, digital/WiFi scheduling, or multiple wire zones.
