Indoor-light harvesting depends on available light and usage. Choose a location with sufficient daily light.
Now playing right in your browser — no YouTube needed.
Why LumaViva
It keeps a little daylight — just to light your way back. A night light that runs on the light you already have.
Harvests indoor light
An OPV panel silently gathers ambient light — by the window or by the bed. No outlet required.
Long-life capacitor
Energy is banked in a long-life capacitor, not disposable batteries. Frequent shallow cycles, far less replacement.
Warm glow on motion
A soft, 2700K LED tuned for bedrooms — PIR-triggered, gentle on the eyes, easy on sleep.
How it works
Explore OPV technology & Chasing Light ↓
Three quiet steps between the light in your room and the glow by your bed.
Harvest
An OPV panel collects ambient light — sunlight by the window, lamplight on the desk. Choose a spot that sees several hours of light each day.
Store
A long-life capacitor banks the energy through the day, holding a calm reserve for the night.
Glow
After dark, a 2700K LED releases a soft, warm light — PIR-triggered, no switch, no batteries to swap.
Indoor harvesting depends on the light source, placement, daily exposure and activity. Choose a location with adequate indoor light. Understand testing and operating conditions →
Everyday light.
A small source of possibility.
Discover organic photovoltaics — and the work of Guangzhou Chasing Light (追光科技) in bringing ambient-light energy harvesting into everyday devices.
01 / Light becomes electricity
A different kind of solar technology.
OPV stands for organic photovoltaics. Its active layer uses organic semiconductor materials to absorb light and convert it into electrical energy. Suitable indoor lighting can be a source of energy, alongside daylight.
Inside the material, absorbed light creates electrical charges. Those charges separate and travel to electrodes, producing a small electric current that a device can collect.
For LumaViva, that principle becomes a simple daily rhythm: gather light, store energy, and use it for a gentle glow later.
02 / Why organic photovoltaics?
Designed to fit into daily life.
Chasing Light describes OPV as a thin, lightweight technology that can be made flexible, with adjustable colour and transparency. These possibilities help designers integrate light harvesting into compact electronics and connected devices.
Its ability to collect energy from suitable artificial light makes OPV especially relevant to products used indoors. Output still depends on the light source, brightness, panel area and placement.
03 / Meet Guangzhou Chasing Light
From organic materials to useful energy.
Founded in 2020, Guangzhou Chasing Light Technology Co., Ltd. focuses on the research and commercialisation of organic semiconductor materials and devices. Ambient-light energy harvesting is central to its work.
Its website presents OPV applications across consumer electronics, smart homes and the Internet of Things. Its OPV introduction also describes scalable fabrication methods such as roll-to-roll printing and slot-die coating.

Four details you can feel.
Beyond the light itself — how LumaViva is built to live with you.
01
Recyclable shell
An ABS body designed to be taken apart and reused — not a sealed unit headed for landfill.
02
Sticks where the light is
A magnetic base snaps to metal surfaces, or to the included adhesive steel plate on a shelf or desk.
03
Three quiet colours
Soft pink, mint green and sky blue — pick the glow that fits your room, not the other way around.
04
Warm, low-blue light
Tuned to 2700K with reduced blue content — gentle on sleep, easy on the eyes at 2 a.m.
A little light for life at home.
From bedtime whispers to a midnight glass of water. Find a place for LumaViva in your everyday moments.
A little comfort at bedtime.
A warm little glow for the moments before goodnight.
For that midnight glass of water.
A little light for a quiet pause after dark.
Stay a little longer.
Soft light, a favourite film, and everyone together.
A little light. A moment uninterrupted.
Keep the quiet. Let a little warmth stay close.
Bedrooms
Soft glow on motion for late-night moves
Hallways
Gentle light between rooms after dark
Entryways
A warm welcome when you come home
Magnetic mount
Snaps onto a metal surface that gets daily light
Adhesive steel plate
For shelves, desks and other bright spots
Tabletop stand
Place it where light already gathers
Suggested placement: a table or shelf with around 5–8 hours of adequate indoor light per day. Wall spots far from windows may not get enough · Approximately 5-year design-life target* · Primarily for indoor use, keep dry and avoid prolonged direct heat.
*Design target, subject to engineering validation. Actual performance depends on light and use.
Small light. Many little moments.
A closer look at LumaViva, from quiet evenings to your favourite corner.
A real prototype — here's where we are.
We're a small team at LumaHarvest. LumaViva started with our own 2 a.m. hallway walks.
Our first production run is complete. Backer units will carry the LumaViva name.
Backer units will ship from this first production run.
From indoor light to a working product.
