The lighting plan

Every fixture has a number and a reason.

It starts with strong design. We'll place markers on your property showing precisely where each fixture will be installed, and create a detailed diagram numbering every light used (We will provide the diagram to you post-installation).

  • Well-lit grounds provide safe passage for you, your family and your visitors.

  • The illumination of gardens, trees, shrubbery and ground cover extends the beauty of nature into the nighttime and enhances your environment and property.

  • We choose lights that match your needs, from safety and security to atmosphere and appearance.

  • We place fixtures so they blend into the surroundings while drawing attention to the lighted area.

  • Lighted areas offer new ways to enjoy your environment after dark.

  • Illuminating your garden, trees, walkways and outdoor statuary transforms your property's night-time appearance.

Then it goes in, in a day.

Our claim-to-fame is our IN & OUT in a DAY! We have pioneered the 'Rapid Installation DML Method'; Our employees pre-assemble lighting systems at our facility. We apply this aspect of our work to all lighting, generator, and Tesla installation projects, at any budget.

Electricians and landscapers work together to seamlessly implement and test your lighting system while leaving your property pristine.

What adds value to your property?

Breathtaking lighting. Reliable generators. Tesla charging stations.

Landscape and interior

Lighting design

The illumination of gardens, trees, shrubbery and ground cover extends the beauty of nature into the nighttime and enhances your environment and property.

While we're installing the new fixtures, we protect every aspect of your home. We remove furniture from the installation area and cover art and draperies with plastic sheeting.

Generac authorized dealer

Standby generators

We sell and install home stand-by generators. Generators not only light up the house in case of power outages but can also provide power to run appliances like air conditioners, refrigerators, furnaces, television and heaters.

Electric vehicles

Tesla charging stations

Home charging, installed by the same electricians who wire the lighting and the generator, on the same one-day method.

01

Design

We select fixtures that create the perfect balance and effect for your home's interior or landscape.

02

Installation

Our team of electricians and landscapers install your custom lighting solution quickly and professionally, and a clean-up crew will give your grounds a manicured look.

03

Maintenance

A maintenance contract protects the integrity of your lighting system through regularly scheduled visits.

04

Reliability

Maximize the security features of your lighting system with a back-up generator that turns on automatically during a power failure.

Five ways to place a light

Where can I get well-lit designed lighting that doesn't make my home look like a gymnasium?

We use a variety of lighting techniques to create a balanced, multidimensional effect that enhances your property's visual appeal.

A tree lit from above at night, beside a drawing of the light cone falling down through the branches.

Moonlight

A fixture high in the tree, aimed down, so the branches throw their pattern across the lawn.

A tree lit from several sides at night, beside a drawing of two light cones rising from the ground.

All-around

Several fixtures around the base, so the whole tree reads from every side.

A low hooded fixture lighting a garden bed, beside a drawing of the light spreading wide and flat.

Spread

A low, hooded fixture over a bed, so the light falls on the plants and not in your eyes.

A path fixture lighting a walkway and the shrubs beside it, next to a drawing of the fixture and its pool of light.

Path

Low fixtures along a walk, with the light pooled on the ground where feet go.

A tree lit from one side at night, beside a drawing of the light cone aimed from the viewing direction.

Direct

One fixture aimed from the side you view it from, so the face of the tree is lit and the back falls away.

Your property's natural beauty drives our lighting design. Using fixtures that blend into the surroundings keeps focus on the area being illuminated.

Designing lighting in harmony with location also protects the environment. We consider how fixtures will integrate with your plants and use enough cabling to allow them to be moved as your landscape changes.

The story

As beautiful at night as it is by day.

Mark Mosello followed in his beloved uncle's footsteps in choosing a career as an electrician. He quickly established his own business, beginning in 1968 with the purchase of an old milk truck and the determination to "never walk away from a job."

Mark found his specialty while working for a customer in Scarsdale, where he suggested lighting a magnificent tree so that it would look as beautiful at night as it did in the day. The client was skeptical, so Mark struck a bargain: He would install the lights permanently so the client could view the effect with the understanding that if the client didn't like it, he'd remove it. The customer was delighted with the effect, and soon, other people who noticed the tree's lighting began seeking Mark to design landscape lighting for their homes. Mark hired an ad agency to promote his innovative new business to homeowners and businesses throughout the tri-state area. The late 1970s campaign featured a series of ads promoting the theme "Lighting for the '80s".

We can't compete with the beauty of natural light, but we get extraordinarily close.

Mark Mosello

"Design Lighting by Marks has been quietly lighting Westchester homes indoors and outdoors with elegance and safety for over 45 years."

Want to switch the lights on when they go out?

Maximize the security features of your lighting system with a back-up generator that turns on automatically during a power failure.

Our employees pre-assemble lighting systems at our facility. We apply this aspect of our work to all lighting, generator, and Tesla installation projects, at any budget.

Ask about a generator
"I wanted to let you know that all's well after Hurricane Irene thanks to the generator you installed last February. We lost power at 1:30 a.m. Saturday night. I was sleeping like a baby, knowing the generator was ready. When the power went out, my son let me know the generator had kicked in. I thanked him for waking me up, then rolled over and went back to sleep. We went with the smaller 20KW air-cooled unit you recommended. It ran all our appliances without any problems; plus, we were able to watch TV and use the Internet, cook, do laundry and use lighting as needed throughout the outage. The only thing I regret is not installing it five years ago."

Pete

"My pool, my tree canopy, and my home lit up have the neighbors asking where I got my lighting and generator."

Reviews

The talk of the neighborhood.

"It's incredible that, 48 hours after I told you to go ahead, the job was completed. Selecting an outdoor lighting system provider is a matter of choosing the firm you trust will do the right job."

Alan

"I wanted to take a minute to thank you yet again for an excellent job up at the house. Lights for the garage, posts, etc. worked out just as we wanted. The trees down by the pond look beautiful. We rarely say 'that was easy, what shall we do next?' after working with a contractor, but that's how we feel about our experience with Design Lighting by Marks."
Roderick
"Once again, you have created a masterful lighting landscape for our home. We are thrilled with the results. The seamless connection between the 'old' and 'new' lights is remarkable. It's as if you gave the house a surgical facelift; nobody will be able to tell what was done, but they'll notice the brilliant improvement!"
Mark
"The lights look great. They are the talk of the neighborhood! Your team did a good, clean job of installing."
Eric
"Kevin and the guys did a great job! The room looks fantastic! You're lucky to have such quick, clean workers. Thanks for all the extras!"
Sherry
"The new lights look terrific. I really like how we've lit up the tops of the tall trees in the back."
Richard
"I want to express how impressed I am with your firm's speed, professionalism and quality of work."
