What Pond Lighting Costs to Install and Run
Fixture quality, transformer sizing, cable runs, and the real yearly electricity cost of lighting a pond or waterfall on the Central Coast.
In short
A professionally installed low-voltage pond lighting scheme in the Bay Area typically runs $1,200 to $3,500 for four to eight fixtures, a transformer, and buried cable. Running cost is small: eight 5-watt LEDs on six hours a night come to roughly $10–15 a year at current PG&E rates.
Lighting is one of the few parts of a water feature where a modest budget buys a large visible change. It is also where cheap components fail fastest.
What drives the installed price
Fixture count and fixture quality, mostly. After that, how far the cable has to run from a power source, and whether the route crosses hardscape that has to be cut and patched.
- Brass or copper fixtures: $90–220 each; cast aluminium: $40–80 and shorter-lived near the coast
- Transformer, 150–300W with photocell and timer: $180–450
- Cable, conduit, and trenching: $8–20 per linear foot depending on surface
- Design and commissioning — aiming fixtures at night is a real, billable step
Running cost is genuinely small
LED changed this completely. Eight 5-watt fixtures burning six hours a night use about 88 kWh a year — call it $10 to $15 on a typical PG&E residential rate. A timer or photocell keeps that from drifting upward.
The pump, not the lighting, is what shows up on a water feature's electricity bill.
Where to spend and where not to
Spend on fixtures and on the transformer. Save on quantity — a four-fixture scheme placed well beats a ten-fixture scheme placed evenly, and it costs less to install and maintain.
Common questions
- How much does pond lighting cost to install?
- Typically $1,200 to $3,500 in the Bay Area for four to eight quality low-voltage fixtures, a transformer, and buried cable. Long cable runs or cutting through hardscape push it higher.
- How much electricity does pond lighting use?
- Very little. Eight 5-watt LEDs running six hours a night use about 88 kWh a year — roughly $10 to $15. The pump, not the lighting, drives a water feature's power bill.
