About Us
I Am Sheree Liu
Since childhood, I have had a special sensitivity to light—the shadows under streetlamps, the lighting in shopping malls, the corner where I did my homework under a desk lamp. Light brings me brightness, and also warmth. Those changes in light have always sparked my curiosity.
From Salesperson to Entrepreneur: 12 Years Deepening in Commercial Lighting
My real connection with light began during the boom of LED technology in the lighting industry. I visited countless renovation sites and saw too many stores where poor lighting design ruined the atmosphere—some were too dark, some had glaring眩光, some had messy color temperatures that distorted the products. I realized that good lighting is not simply "installing lights", but pursuing "light quality" – understanding the space, the products, and people's feelings.
In January 2014, my husband and I founded Shenzhen Ruituiming Electronics Co., Ltd. Back then, the commercial lighting market was full of chaos. Many suppliers only sold灯具 but ignored lighting design; or the design looked great on paper but the delivered products were completely different. I decided to take a harder but more correct path: integrated service of "lighting design solution + customized product manufacturing".
Full-Link Closed Loop: From Needs to Delivery
We do not sell lights first; we first understand the customer's store. From brand identity, product type, customer flow layout, to color temperature, CRI, beam angle, glare control – every parameter is carefully considered. After the design is finalized, we custom-manufacture the luminaires to ensure every beam angle and every watt of brightness is precisely realized.
This approach earned us the trust of our customers. Gradually, some listed companies and well-known chain brands began to find us. We now deliver lighting solutions for over 1,000 stores per year, covering the entire closed loop from solution design to customized product delivery. In the niche of commercial store lighting, we have survived and thrived on word of mouth.
My Understanding of Light: Light is the Soul of Space
Just as streetwear has elements like skulls, graffiti, and roses, commercial lighting has its own design language:
Color temperature – warm white relaxes, cool white sharpens
Color rendering index (CRI) – high CRI makes food look more appetizing and clothes more real
Beam angle – narrow angles spotlight products, wide angles create ambiance
Glare control – let customers see the light, not the fixture
Accent lighting – "paint" the core selling points with light
Layered lighting – ambient, task, and accent – none is dispensable
These are not just technical specs; they reflect how seriously we take every store.
New Horizons: From Commercial Lighting to Plant Lighting, from Domestic to Export
In 2023, I noticed a brand new direction: plant lighting. Modern agriculture, indoor growing, home gardening – light is just as vital for plant growth. We began to study plant spectra, photoperiod control, LED heat dissipation and energy efficiency, hoping to extend our optical design and manufacturing expertise from commercial lighting to plant lighting.
At the same time, I embarked on this new exploration with great passion for plant lighting. In 2023, when I first saw plants thriving under specific spectra, I was deeply touched – light not only illuminates spaces, but also nurtures life. Since then, I have been studying plant spectra and photoperiod control carefully. The direction of every leaf, the strong growth of every seedling – these things touch my heart. I want to transform our expertise in commercial lighting into gentle care for plants.
It is this understanding of "light and life" that inspired me to go global. For the past decade, we have deeply cultivated the domestic market and served countless stores. Now, I want to bring this respect for light and care for plants to customers around the world. Whether it is a chain supermarket in Southeast Asia needing energy-efficient commercial lighting, or a greenhouse farm in the Middle East longing for a spectrum that makes tomatoes sweeter and lettuce crisper – we are willing to listen, design, and deliver with heart. Step by step, we are going global – with light, and with warmth.
Our Quality Commitment: Light – No Compromise
At Ruituiming, we have established our own light quality control process:
Light source parameter test – color temperature, CRI, luminous flux, color tolerance – every parameter is actually measured.
Heat sink structure verification – ensuring no lumen depreciation over long-term operation.
Burn-in test – every batch undergoes 48+ hours of aging test.
Waterproof & dustproof test – for outdoor and humid environments.
100% final inspection – no defective light leaves our factory.
We may not be the biggest company in the industry, but we are the partner you can trust with your products. Whether it’s a commercial chain store, a small plant factory, or a flower shop, we treat every project with the same standard.
Light deserves to be taken seriously.
