A ten times brighter beam
Smartphones' flashes are unable to light up far away objects, because they cast a wide beam to evenly illuminate closer subjects.
Flens gathers these rays and generates a tighter, ten times brighter beam, able to light up subjects in total darkness up to 10 metres away.

Improved shots at a distance
Flens makes smartphones capable of shooting photos and videos at great distances in the night.
By shrinking the illuminated area, more light can enter the camera sensor, reducing ISO sensitivity and producing dramatically more defined shots.
Moreover, it's so small that it doesn't interfere with the field of view of most devices' cameras (you don't see Flens in your photographs).
Flens is compatible with every flash-enabled Apple device, including the newer iPad Pro 9.7 and iPhone SE, even with original covers or third-party ones that honour the Case Design Guidelines for Apple Devices.
Android and Windows Phone compatibility diagram
Flens is compatible with many Android and Windows Phone devices, provided they have a flat, glossy back (not textured) and a flush (not protruding) round flash, whose dimensions and distances are as follows:

Custom-made glass optics
We reverse-engineered common smartphones' flash emission patterns and developed a custom-shaped lens that achieves very high collimation efficiency.
A special kind of high-grade N-BK7 borosilicate crown glass is used, in order for it to be clear, smooth and virtually unscratchable.
How it attaches to your phone
Flens attaches on top of your phone's flash by a tiny neodymium magnet.
Since the back of most devices is non-ferromagnetic (plastic, aluminum), we provide a small carbon-steel adhesive washer to apply to your phone.
The washer is removable and is designed to blend into your smartphone's shape, to be virtually invisible and to not interfere with normal flash operation.
Only premium materials
Designed and assembled in Italy, the accessory is made of premium materials - aluminum, neodymium and a special kind of high-grade glass for the lens - and doesn't lack in design, to complement that premium feel that everyone craves.
At 12mm of width, it's so small it requires a special kind of CNC mill to be processed.
Each Flens is machined from a solid block of Anticorodal aluminum.
Frequently asked questions
How do I get one?
For the moment, Flens is distributed exclusively via Kickstarter. Regular commercial availability is planned for 2017.
Are there specific Flens versions for different mobile phones?
No, there's only one edition of Flens, and it comes with all the required accessories to be attached to every compatible device. General device compatibility is shown in this picture:
What's in the package?
The package contains 1x Flens, 1x lanyard, 1x manual + Certificate of Authenticity, 2x adhesive washers (one round for iPhone 6 style and generic smartphone round flashes, one oval for iPhone 5 style oval flashes).
Do you ship to my country?
We should be able to ship worldwide. If you live in a remote area, please contact us before purchasing.
Do the back magnets interfere with device's internal compass?
Flens magnets form a closed, confined magnetic field. From our lab and field tests, no.
How do you cope with dual-color flashlight that many modern smartphones have?
When operating in steady mode, no smartphone enables the second warmer LED, so you'll always get bright, white light. Luckily, the same seems to happen when you shoot at distance in the dark.
Is the round steel washer removable?
Is it compatible with my cover?
Flens is compatible with every flash-enabled Apple device, even with original or conforming covers. Covers that honour the Case Design Guidelines for Apple Devices should be 100% compatible with Flens. For non-Apple devices, with or without covers, please refer to the compatibility picture shown above.

Fresh ideas from young minds
Love for industrial design, passion for details and excitement about life-improving products are the heritage of our families, culture, passions and jobs.
The DIY approach
We directly managed every step of product developement. Even this website is entirely designed and coded by us!
In 2014 we developed and manufactured the first and only USB light with ultra-high Color Rendering Index (CRI). We called it “The Relio”.
We put Relio in a Kickstarter Campaign, raising more than £54000 in public pledges. Thanks to that, we put Relio into production, selling and successfully delivering thousands of units in just a few months.
Time to grow up... and shrink down!
Flens is the smaller, fresher newborn member of the family. It's a great improvement in terms of engineering and convenience, and it keeps alive the passion that fuelled all our past projects.
