Growing up in Navipet town of Nizamabad district in present-day Telangana, 39-year-old Mandaji Narsimha Chary grew up with a real fascination for science, novelty and experiments.

He received his first medal for building a rotating globe in the third standard of school using a motor from old cassette players and a round ball.

Gradually in his sixth-standard of school, he won an award at a district-level science fair for designing a model showcasing the universe's nine planets' revolution around its axis using light plastic balls.

However, the young mind had no peace until he had opened all the electronic equipment he had found all around.

Life changed for him when he visited the local village, a gram panchayat, near Navipet when he was in Class VII.

Chary noticed thousands of discarded tube lights lying in the premises.

He tells Newslions Media Network, "I asked the officials why are they lying around. They told me, the lights have burnt and are not usable anymore. Something struck me, seeing thousands of tube lights lying on the ground waiting to be discarded struck a chord inside me."

"Back then, I didn’t have access to Google or other online resources, but I was determined to understand how they work, what are the components within, why tube lights fail, among other things. I would even read textbooks that were beyond my grade in school, but just to understand the components that went into running a tube light," he adds.

Following this, he managed to get permission to visit the central library at Nizamabad for a couple of years until 1993.

He studied books on tube lights and understood the working of the electronic components.

"I finally developed a method to re-light discarded tube lights by developing an integrated circuit sometime in 2000. See, these tube lights fail once their filaments open up, and thus lose their capacity to generate the necessary voltage to light them up. Through trial and error over the next decade, using my own pieces of equipment, I first succeeded in lighting a failed tube light with choke and starter," he says.

Today he is an owner of a patent that allows discarded tube lights to re-light up without filaments.

He removed several parts from the tube light and created a circuit using resistors, nichrome springs, diodes, transistors, capacitors and other electrical components.

This does not require a choke, starter, both filaments, frame and even a folder to work.

It consists of a simple circuit housed in a box with pins that connect to each end of the tube light. The simple circuit is connected to the house socket, and there is a glow in an old worn-out tube light.

His tube light can also help fight the environmental pollution as mercury found in the filaments were often discarded with the bulbs which led to groundwater and soil contamination.

This is a way to use up all the residual mercury in the light until it’s safe to discard them.

Chary also claims his tube light emits completely white light instead of blue ones that are hazardous to health.

"I am hopeful about this invention. The world witnessed the first filament-less light. It's a revolutionizing idea, that can be tweaked further to several other inventions," he says.
