To participate in a student design contest, the then 23-year-old Sandra Rey he found himself watching videos on YouTube about sea creatures. Among these, some endowed with bioluminescence produced in their passage a thin luminous halo.
Rey has since set out to replicate this natural technology and today, 5 years after that episode, she was born glow, the startup that creates luminescent installations for public spaces and hotels.

Sandra admits that her creation is unlikely to supplant the living room lights or car lights, but she hopes to create enough light. How much? Enough to play a role in the mix of light that helps the world reduce its dependence on electricity, at least on the "insane" one born from non-renewable sources.
A brilliant story
At the beginning of her research, Sandra Ray says she often worked in complete darkness to be able to distinguish a very faint glow, indistinguishable otherwise.
Like the photographers of the last century, in his "dark room" he waited 10 to 15 minutes for some faint light to be produced. Today it gets much more flattering results, and there is still room for improvement.
One of the first investors to help Sandra was Cyprien Comarmond, CEO of a construction company and today also a member of the Glowee board.
"Glowee can have a huge impact on the environment," says Cyprien. "Creating light without electricity means less nuclear and coal pollution. We reduce the environmental impact with natural substances. And we create an atmosphere, too!"

A sustainable solution
Bioluminescence can be a valid option: fighting global warming by reducing the use of limited resources, waste and pollution is not bad.

Despite the over 10.000 units already sold (in hotels and spas mainly, due to the very relaxing light produced) Glowee is not yet profitable, and the company also finances itself by setting up art installations for events.
Within the next 3 years, Rey hopes to produce a light strong enough to provide outdoor night lighting, or for street furniture, also capable of reducing light pollution in our cities.
Natural light
Glowee light comes from marine bacteria that emit it naturally. These are living organisms, which is why they need maintenance in some ways vaguely similar to that of an aquarium.
And the switch?
There is. The light can be adjusted: with a small device, the bacteria are deprived of oxygen (do not worry, they fall asleep but do not die) and without oxygen the light goes out. Is oxygen replaced? The light comes back on.
Fascinating potential
Glowee light can supplant in some environments both classic and LED. For example, imagine a bedroom with entire bright walls that can provide artistic beauty and the soft night light needed.
Upcoming developments
As said, Glowee is not yet in surplus but with over 4 million euros raised it survives very well. It counts on over 800 small investors who have bet on the company through a crowdfunding platform. A big investor willing to take Glowee to the next level wouldn't hurt, though.
