Part 1
Know Me
Safety is paramount — it all starts with this sentence. When we began Gobo production in India, our focus was branding and advertisement for small shops. But we quickly realized that Indian infrastructure often doesn’t allow users to fully experience this wonderfully simple light projection technology.
We frequently faced the lack of proper throw distance to get a large image on Indian buildings. To solve this, we tried short-throw lenses like 1:1 ratio, but they’re limited to around 5 meters. Suddenly, our market size shrank compared to our initial projections. I genuinely thought this was the end of Gobo lights — and my dream to make the vibrant streets of India more visually colorful and dynamic.
But what I hadn’t noticed was a small yet consistent number of Gobo light orders being placed by factories in Chennai. As we all know, Tamil Nadu is a major manufacturing hub. That was our “swift and hope” moment — for all the investment and research we had put into Gobo glass production during three challenging COVID years.
Finally, in December 2021, we became India’s first Gobo glass manufacturer.
An Unexpected Terrain for a New Business
We discovered that factories were ordering Gobo lights — but not for what we thought. We assumed they were for floor safety signs to create awareness, but the truth was deeper.
The first real clues came through inquiries asking if our product could solve recurring issues in factory safety management. One major issue was wear and tear on painted floor markings. With heavy vehicles like forklifts passing constantly, industrial paint fades in just weeks, making it useless for visual safety.
In contrast, a bright, visible projection from above — one that doesn’t fade and instantly alerts workers — turned out to be a far more effective solution.
The Reality of Factory Floors
Busy factories with tight deadlines and upcoming audits can’t afford lapses. Every turning and blind spot becomes a potential accident zone. Vehicles run constantly — with no pit stops.
Conventional traffic signals are useless here. What’s needed are special attention-seeking lights that notify both operators and ground staff based on real-time movement.
The challenge? Every factory is different.
Detection of people and vehicle movement isn’t uniform. That’s when we learned:
“Not one solution fits all factories.”
We experimented with RFID tags, radars, AI cameras, motion sensors, and safety triggers — and learned each of them works only in the right context.

Cranes vs. Final Destination
Accidents with cranes feel like scenes from Final Destination. I’ll never forget my visit to a Korean company managing tons of steel every minute with a massive EOT crane.
It was my first close-up experience with such a giant crane — it towered 30 meters above my head. When we tested our light on it, I could barely see the glow. The sunlight, height, and distance made our projection look like smoke.
The principle behind these lights is simple:
Higher the wattage → Longer the distance → Larger the image
But ambient light decides the final output.
Trying to mark the floor with precision from that height was tough — but trying it on a moving crane took it to another level.
That’s when I truly understood the risk of not knowing where the crane hook is, especially with tons of weight hanging above. The projection helped operators and ground staff know the crane’s hook position and its movement path.
What Next?
We’re still exploring new use cases inside factories. If you’re looking to make your factory safer, we’d love to hear from you.
