Landscape Design and lighting

Customer extended back yard to lake area at rear of home. Electrician would need to add distribution panel 100amp rating for future power supply.
Electrician added a total of 46 high energy efficient l.e.d low voltage lighting. This light is meant for a soft ambient glow as to relax while outdoors. At 40 dollars each pretty steep but never has to be replaced weather proof light.
*Options I considered for this project:
Many options to choose from we could go with standard icandecent bulbs; are pretty expensive at like 7 bucks each for lamp. Higher maintence to operate, and maintain.Internal wire damage from corrosive termination or socket damage replace or over heating occurs frequently 120 volt power supply. Perks for icandecent lights are that they put out alot more light. Really great for general purpose lighting and direct lights.
Initial lower cost at about 27.00 each for incadecent lighting.
So in a relaxed enviroment I needed a softer light.
L.E.D lighting 40. bucks each definite higher intial cost. Basically no operating cost . Bulbs never have to be replaced, and 7 watt output gives perfect ambient soft glow for relaxation by the lake.
* Cost Comments:
Lights were 40 bucks each 46 lights purchased=1840
labor 30 each to install and trench lighting=1380
*Project Steps:
First step was power supply for future lights and power supply for pump circulations water fall. 100 amp distribution was cheap wire cost triplex from H D at like 1.40 a foot awesome price. Panel and breakers 150.
Laying lights out, focus on all trees was key they were put there for a reason.
Wall wash on retaining walls.
lights in water fall x 3 power supply for pump circulations. lights for both sets of steps. And one general purpose light, and one general purpose outlet.
Advice:
There were 46 lights total installed every tree accounted for during day time work.
Tech had to make second visit at night to get the real picture from across lake. Pictures are really hard to express in night time for soft ambient light hard to capture on camera.Shadow spots on retaining wall were corrected on night visit by adding additional lighting.
Basic no cost to operate.
Now 46 lights at a 120 volt 75 watt each =3450 watts. incandescent major difference in operating cost present and long term.
