Now, his light shows have become one of the most highly-anticipated events in Williamsville every year for the Christmas season.
Mc Lean uses computer programming to create the stunning light shows, complete with Christmas carols, pop music, local soca and parang tunes.
He starts preparing from October where he spends sleepless nights programming the lights.
"Right now I am using LED lights on my tree that are capable of lighting up to 512 colours but I have to programme every colour in the bulb itself," he told the T&T Sunday Guardian.
"About four years ago, my youngest child asked me to add music to the lights and since then, I have been doing it every year."
It is a tedious task, but Mc Lean said it was all worth it when he sees the looks on the faces of his children and even strangers when the show comes to life.
"I let my children choose the songs and for every song that I want to add I have to sit and manually turn lights on and off.
It's done to sequence the lights to the music and then I programme the sequence into the control unit for the lights."
The T&T Sunday Guardian visited his home one night for a sneak peek at this year's production. Mc Lean fired up the show, starting with Adele's 2015 hit, Hello.
He even programmed a giant Christmas tree in his yard with the message 'Hello Guardian.'
The show was nothing short of stunning, a perfect mixture of the magic of Christmas and technology.
He estimated that there are almost 150,000 lights in the show.
Mc Lean's wife, Dianne, is part of the genius behind the extravagant light shows.
She said the shows are a team effort but admitted it was not easy to put together a show to wows visitors year after year.
"We usually start to prepare by October, sometimes we'll be up at 2 am adjusting the designs."
The launch is traditionally held the Sunday before Christmas and the lights are left up until mid-January.
While he was hesitant to reveal the cost, Mc Lean said the LED bulbs are quite expensive but last longer than regular incandescent bulbs.
"Every year, I would buy the normal incandescent bulbs by the cases but I made up my mind that this is the last year I am buying Christmas lights, because these tend to blow quickly while the LED lights can last up to five years."
Mc Lean said a few years ago they started inviting people over when they were ready to turn on the lights.
"This year is no different. I expect we will draw quite a crowd," he added.
As for next Christmas, he is hoping to offer his magic-making skills to those who want their homes to stand out as well.
