Walter Tse — Founder of iLightin
Commercial Lighting Manufacturer · Engineering-Driven · OEM/ODM Specialist
I’m Walter Tse, founder of iLightin.
My journey in lighting didn’t start with marketing—it started on the factory floor.
For years, I worked side-by-side with engineers, SMT operators, QC staff, and project managers. I learned how a small design choice—an aluminum thickness, a gasket shape, a lens structure, a driver spec—could determine whether a light lasts five months or five years.
Today, I work directly with global B2B buyers who need more than a catalog.
They need clarity, engineering logic, and products that will never embarrass them on-site.
Whether you manage a retail chain, lighting brand, or construction project, my goal is simple:
make your lighting decisions easier, safer, and more profitable—with products built by a factory that understands what’s at stake.
About Me
I’m Walter Tse, the founder of iLightin, and my work sits at the intersection of engineering, manufacturing, and real-world commercial lighting applications.
My career didn’t begin with sales or catalogs—it began with solving problems.
Before building iLightin, I worked closely with overseas buyers who were struggling with issues that shouldn’t happen:
flickering lights in retail stores, overheating downlights in hotel lobbies, IP65 fixtures failing in kitchens, and batch inconsistencies that caused expensive rework.
I realized many of these failures weren’t caused by bad products—they were caused by missing engineering logic.
Wrong LED modules, mismatched drivers, insufficient heat sinks, inconsistent sealing pressure, poor optical control, or simply assumptions that didn’t match real-world environments.
That’s what pushed me to start iLightin:
a manufacturer where every product must make sense—technically, commercially, and operationally.
I’m deeply involved in every stage of production:
✅ LED & Driver Engineering
Choosing the right LED suppliers (Osram, Nichia, Cree, Bridgelux, Hongli), validating current design, ensuring long-hour stability, and matching drivers with precise loads.
✅ Optical Design & Light Quality
Testing beam angles, glare control, lens/reflector performance, and color consistency—so lighting works for designers, not against them.
✅ IP65/IP67 Structural Engineering
Evaluating gasket compression, sealing materials, anti-condensation design, venting, and actual long-term durability.
✅ Thermal & Mechanical Engineering
Reviewing aluminum thickness, heat sink capacity, driver compartments, and mass distribution to ensure safe operating temperatures.
✅ QC, Aging Tests & Batch Control
Inspecting every batch with temperature cycles, lumen maintenance checks, ΔE < 1 color tests, and real aging—not just “power on for 20 minutes.”
✅ Packaging & Export Optimization
Designing packaging that prevents cracks, dents, or failures during long-distance transport to Europe, the US, and beyond.
But my role isn’t just production.
I spend a large part of my time helping clients understand the engineering behind their decisions—because a lighting choice isn’t just a product choice; it’s a risk choice.
What I’ve learned after years of supporting OEM/ODM brands, retail chains, engineers, and lighting designers is simple:
People don’t need a supplier.
They need a partner who can see around corners.
Someone who can say:
“This beam angle will create unwanted shadows.”
“This thermal design won’t survive long-hour use.”
“This IP65 is not real IP65.”
“This LED bin isn’t stable for your application.”
That’s the value I bring.
When you work with me, you get more than manufacturing capacity—you get:
✅ Engineering logic
✅ Real-world practicality
✅ Transparent communication
✅ Hands-on involvement
✅ Dedication to long-term reliability
And above all, you get a partner who treats your project as if it were mine.
Lighting isn’t just about lumens or watts.
It’s about reducing risks, elevating spaces, and building trust through products that simply don’t fail.
That’s what I do at iLightin.
Areas of Expertise
My expertise is simple: I help clients avoid technical blind spots that cost money, reputation, and time.
- Downlights & Spotlights
I guide buyers on which beam angles, UGR levels, heat sink size, reflectors, and lumen packages truly matter for commercial spaces—not just for spec sheets.
- Optical Engineering
Most lighting decisions fail here.
I explain what photometric files actually mean, how beam spill affects merchandising, and how lens vs reflector choices impact glare and comfort.
- IP65/IP67 Waterproof Design
Real waterproofing has nothing to do with the sticker.
I help buyers evaluate gasket compression, venting, moisture paths, driver separation, and sealing lifespan—so their products survive kitchens, bathrooms, and semi-outdoor spaces.
- Thermal & Mechanical Design
I analyze LED module heat flow, housing design, driver placement, and aluminum mass to ensure commercial-grade stability under long operating hours.
- OEM/ODM Manufacturing
I work with brands, designers, and retail chains to create custom fixtures that fit their identity—while ensuring consistent batches, fast production, and reliable compliance.
- QC, Aging & Reliability
I help clients understand what real QC looks like:
component checks, temperature cycles, lumen maintenance, ΔE < 1 consistency, real aging tests—not just “passed QC.”
Factory Insights
Running a lighting factory teaches you humility.
Every day, I’m reminded that quality is earned—not claimed.
I walk the floor daily:
reviewing SMT lines,
inspecting solder joints,
checking LED bins,
testing IP65 chambers,
running IES tests,
analyzing heat dissipation curves,
validating driver stability under load,
tightening mechanical tolerances,
reinforcing packaging for long-distance export.
I’m hands-on because projects depend on reliability.
If a fixture fails in a hotel lobby or a retail store, it’s not only a product issue—it’s a business problem for my client. And I take that seriously.
This is why I personally supervise batch consistency, sample approvals, and production timelines.
When clients work with me, they don’t just get manufacturing capacity—they get engineering accountability.

My Writing Philosophy
Most lighting problems start with assumptions—
assumptions about wattage, lumen output, beam angles, IP ratings, or thermal performance.
So I write to help clients see what really matters:
✅ how to choose optics that don’t create glare,
✅ how to avoid fake IP65 structures,
✅ how to evaluate thermal design beyond the datasheet,
✅ how to compare LED modules with logic,
✅ how to ensure color consistency across large orders,
✅ how to verify a supplier’s engineering capability, not just their claims.
My writing is not marketing—it’s experience.
Every article comes from real factory work, real engineering challenges, and real customer projects.
If my insights help one buyer avoid a costly mistake, then they’ve done their job.
