会社のニュース Canadian Stage Engineer’s "Lighting Emergency" and Lanjin’s Perfect Solution

In November last year, on a cold evening, we Lanjin received an urgent email from Mark, a stage lighting engineer based in Vancouver, Canada. He was preparing the lighting setup for a well-known winter music festival called Light of Snow Festival, but the lighting tests were failing.

His email was very straightforward:

“The RGB LEDs I’m using are flickering at low brightness. The color shift is too visible, and I can’t synchronize the strips properly.”

The root issues were typical:

1. The RGB LEDs he purchased were low-quality and not BIN-controlled.
2. The color difference between batches was noticeable.
3. Severe flickering occurred at low brightness.
4. The longer the strip, the worse the synchronization issue.

Mark had only 10 days to fix everything; otherwise, the entire lighting plan would need to be redone.

✔ Lanjin Team Stepped In Immediately

We asked Mark to send us:

1. His controller protocol
2. The strip structure
3. Stage layout and installation distance

After reviewing all the data, we identified what he truly needed:

1. Individually addressable LEDs with built-in ICs
2. Strict BIN control to ensure color consistency
3. RGB LEDs that stay stable even at low current
4. High-frequency PWM to avoid camera flicker

Based on these requirements, we recommended:

1. 5050 RGB LEDs with built-in IC (WS2812)
2. 6028 RGB LEDs with IC (for corners and structure transitions)

To help him make a fast decision, we also provided:

1. Low-brightness anti-flicker test videos
2. MacAdam 3-step color binning data
3. Long-distance synchronization demonstration
4. Stage lighting simulation images

After watching the test videos, Mark finally sounded relieved:

“This is exactly the performance we’re looking for.”

✔ The Final Outcome

Within three days, Mark confirmed and placed an order for 30,000 pcs of the LEDs.
When everything was installed, he sent us a new video of the stage lighting transitions.

The colors were smooth, uniform, and flawless.
He wrote:   “Lanjin LEDs literally saved our winter festival.”

Since then, we’ve become their long-term supplier for all seasonal events, including spring, summer, and winter festivals.

✔ Why Mark Trusts Us

Mark chose to continue working with us not because of price, but because:

1. We were able to accurately diagnose the issue within a short time.
2. We provided engineering-level testing and proof, not guesses.
3. We offered strict color binning and stable IC LEDs.
4. We focused on solving the problem, not just selling products.

What truly builds trust is not the LED itself, but our ability to understand the project deeply and deliver reliable solutions.
