What is a 150W landscape lighting transformer?
A 150-watt low-voltage (12V) transformer steps household 120V to safe 12V power for outdoor lights. The Contractor Essentials LT3150 delivers up to 150W with multi-tap 12V–15V outputs to combat voltage drop.
How many lights can a 150W transformer run?
Add the wattage of all fixtures and keep total load at ≤80% of capacity. Example: 12 fixtures × 6W LED = 72W total. Rule of thumb: aim for ≤120W connected load on a 150W unit.
Is a 150W landscape transformer big enough for my yard?
For small–medium LED systems (about 8–20 fixtures depending on wattage and run length), yes. For longer runs, higher-wattage fixtures, or future expansion, consider a second run or stepping up to a 300W unit.
What does “multi-tap 12V–15V” mean and when should I use each tap?
Multi-tap lets you choose 12/13/14/15V to offset voltage drop on long runs.
- Short runs (≤50 ft): 12V
- Medium runs (50–125 ft): 13–14V
- Long runs (125–225+ ft): 15V
Always verify far-end fixture voltage is around 10.5–12.0V.
Does the LT3150 work with LED and halogen lights?
Yes. It is compatible with both. Recalculate load for halogen since it draws more wattage.
How far can I run wire from a 150W transformer?
Distance depends on wire gauge and load. With 12-gauge cable and LED loads, 100–200 ft per run is typical when using the correct tap. For very long runs or heavier loads, use 10-gauge wire or split into multiple runs.
What wire gauge should I use with the LT3150?
Most installs use 12-gauge. Use 10-gauge for longer or higher-load runs to reduce voltage drop. Size wire for both amperage and distance.
Is ETL the same as UL for this transformer?
Yes. The LT3150 is ETL Listed to the same UL safety standards recognized by inspectors across the U.S. and Canada.
What’s the difference between a 150W and 300W landscape transformer?
Capacity and headroom. Both can be multi-tap and stainless, but 300W supports more fixtures/expansion on fewer runs. 150W is compact and ideal for most mid-size LED systems.
Can I control a 150W transformer with a timer or photocell?
Yes. The LT3150 supports optional timer/photocell control (accessories). You can also control the primary side with a properly rated outdoor smart plug.
Can I install the LT3150 myself?
Many homeowners do. Mount above grade, use GFCI-protected power, follow local codes, and check fixture voltage at the far end. Hire a licensed electrician for larger or code-critical installs.
Is the enclosure weatherproof and durable?
Yes. The LT3150 uses heavy-duty stainless steel with a lockable cover and is designed for outdoor use.
What’s the warranty on the LT3150?
Lifetime on the stainless-steel transformer housing and core; 5-year coverage on accessories such as timers and photocells.
