Replace disposable batteries with solar energy
Every year, billions of disposable batteries are used once and discarded, polluting our environment. But what if one solar lamp could replace thousands of those batteries? With BRIGHT's innovative solar-powered products, that future is within reach.
A brighter future without battery waste
Did you know that a solar lamp from BRIGHT can replace up to 8,500 disposable batteries? That's not just savings for your wallet — it's a huge win for the planet. Much like how LEDs have replaced inefficient incandescent lightbulbs, solar-rechargeable batteries are poised to replace traditional disposables. BRIGHT’s products harness the sun's energy and store it in high-efficiency lithium-based batteries — dramatically reducing waste and environmental harm.
Disposable vs. rechargeable batteries: A clear difference
How they work:
- Disposable batteries: One-time energy transfer; high environmental cost
- Rechargeable batteries: Repeated energy transfer; environmentally sustainable
Environmental impact:
- Rechargeable batteries emit 28% less greenhouse gas emissions than disposables over their lifetime
- BRIGHT's lithium batteries outperform alkaline batteries, especially in cold weather, where disposable batteries often fail.
The alarming reality of battery waste
In the EU alone, approximately 160,000 tonnes or around seven billion alkaline batteries are sold each year. Shockingly, only 44% are recycled according to Eurostat, with Norway trailing at just 32%. Many batteries contain hazardous substances like lead (Pb), mercury (Hg), or cadmium (Cd), increasing their environmental threat.
