Let's start from the basics.
We make Relio² here, in the hills of Northern Italy, with the utmost precision.
It's a symphony of hard work and knowledge, and we want to share this journey with you.
Color Rendition is the ability of a white light source to faithfully represent the colors of objects and surfaces illuminated with it.
Relio² is engineered to emit a light comparable to Sunlight, in terms of purity, concentration and color rendition.
Improved Color Separation
Typical LED lamps favour energy efficiency at the cost of spectrum continuity: that leads to unsatisfactory color rendition.
Relio² emits a continuous spectrum of visible light, improving color clarity and making the subltlest color variations more apparent to cameras and naked eyes.
Studio-grade Optics
To achieve maximum color rendition and flux intensity, we gave Relio² an exceptional kind of TIR optics.
It's a 2-stage collimation system, where a multitude of superficial micro-domes furtherly homogenizes the chromaticity of the emitted light.
The smoothness of Relio² light is unmatched.
State-of-the-art Light Quality
Relio² light is certified and calibrated by professional spectrophotometry testing.
The results? An impressive 98% native TLCI and more than 40.000 lux @ 25cm.
We perform all the test in our laboratories and make the results available for download.
100% TLCI with zeroing LUTs
If you are a serious filmmaker or a scientist, you’ll really like this... it’s a world’s first!
We give you the spectrum-based LUTs of Relio², to be applied before any other post-processing act.
This gives you a perfect, “ideal-world” starting point to apply other LUTs with 100% color consistency.
Science-Backed Engineering
We did our homework.
Back in 2014, the Original Relio was the first portable ultra-high-CRI device in the world.
Relio² is backed by 4 more years of research, and we published a technical paper to document our engineering choices.
Beware of imitations and clones!
Relio² brings the concept of modularity to a whole new level.
It's the first device that can be shaped either into a wall, a ceiling, a shelf or a desktop lamp.
The minimal footprint makes it practical and incredibly unobtrusive.
- Mix, Combine, Reshape
A picture is worth a thousand words.
One modular Base can host up to 5x Relio² elements.
Combine multiple Base kits to create and expand your ideal lighting setup.
Are you done? Unmount. Remix. Remount. ...Repeat!
- The Modularity Core
Relio² is an instrument that loves standards.
Both the lamp module and the Base kit use a standard 1/4-20 UNC “camera mount” thread.
The slotted Base can host up to 3x rods.
Finely machined stainless-steel caps cover the unused slots on the Base.
- The Mounting Core
Neodymium magnets and anti-slip foam pads generate more than 10Kg of attraction force, to allow both a safe horizontal and vertical placement.
For non-magnetic surfaces, we give you 4x metallic washers to apply on the desired material.
On the Base, we even put a slotted notch: use it to hang Relio² on wall-protuding pins.
- Degrees of Freedom
Each lamp module has full 360º rotational freedom on both axes.
This still holds true when combining multiple Relio² units on the same Base.
No tools required: the adjustments are made by hand.
- Interchangeable Lenses
How’d you call a light modular”, without a full set of interchangeable lenses?
Swap the optics on each Relio² lamp element, and make it either a spotlight or a floodlight.
The Base kit includes 10º, 25º, 60º lenses and one special 10×70º asymmetrical lens.
The Desk kit includes an additional, larger 90º lens.
- Cable Management
On the bottom, a T-shaped passage allows for many elegant takes on cable management.
Thanks to the ultra-slim foam pads that protude for just 0.4mm, the cable will stay firmly in place.
We firmly believe in product longevity, so we designed miniaturized, upgradeable, robust electronics that embrace the most advanced technologies available today.
It’s a tiny work of art, indeed.
Ultra High-end Circuitry
USB power and no internal battery: the right combination for many years of continued use.
With durability in mind, we engineered the most complex electronics ever in a device of this size.
To withstand mistreatment, the USB port is reinforced, and the USB cord is magnetic and user-replaceable.
Relio² is so efficient that a single USB power-pack can power it for days.
Official App Available Free!
With our official App, you can wirelessly control Relio² brightness level via Bluetooth®.
We designed a proprietary “Halogen-like” algorithm that tweaks Relio² dimming curve to simulate the afterglow of traditional incandescent lamps.
For use in open spaces or laboratories, the App includes a “Secure mode” and a “Strobe mode”.
Ultra Slow-motion Suitable
Relio² light is so stable that is guaranteed flicker-free up to 10.000 fps.
A rarity: that still holds true when the light is dimmed.
Thanks to Relio² extermely high luminance, it’s a perfect companion for slow-motion macro shots or scientific image acquisition.
Laboratory Use
Relio² can also be dimmed via external microcontrollers like Arduino® and Raspberry-Pi®.
The electronics can operate up to 15V DC and will withstand lightning surges up to 20.000 Volt.
Digital inputs are protected too, and our Bluetooth API is public and fully documented. Neat, huh?
Relio² incorporates the rarest wavelengths available, from world‘s best LED manufacturers.
All Relio² owners will be eligible for the Upgrade Program, the day we’ll release newer, backwards-compatible Relio² upgrades.
After all, it‘s all about light quality, and we‘re very serious about it.
#STUDIO - Premium Whites
Relio² comes in 3 different white spectrums.
When performing color critical-tasks, using calibrated light is a way to certify and add value to your work.
If undecided, pick the 4000K version: it has a neutral white point that is accurate, pleasant and warmer than you may expect.
A real joy for your eyes and cameras.
#ART - Premium Colors
As for the white versions, we managed to cherrypick the most rare and unseen color spectrums.
They’re best suited for artistic or colorimetric purposes.
Their high purity, saturation and peak wavelength are something you’re not used to see.
#LAB - Technical Colors
A journey into the unseen always begins with the right light.
Relio² can be equipped with a full set of Ultraviolet and Infrared LED variants, including the most technologically advanced full-spectrum IR emitters.
Upon request, we can offer tailored wavelengths for scientific or research use. Contact us for information.
Base Kit is the foundation.
Use it to build modular, expandable sets to attach to walls, ceilings, shelves or camera tripods.
Desk Kit has even more parts.
Use it to transform Relio² into a color-calibrated desktop lamp.
Thanks to its minimal footprint, Relio Desk pushes the boundaries of what a “Desktop Lamp” can do.

Frequently Asked Questions
How do I get a Relio² kit?
Currently, Relio² is sold exclusively on this website.
Does it have an internal battery?
No. We want Relio² to withstand years and years of 24/7 use. An internal battery in such a small and powerful device would be able to power Relio² for just 15 minutes at full brightness, with a lifetime spanning no more than 6 months. Name - if you can - one product with an integrated, non-removable battery that’s still 100% funcional after years of use...
How do I power it up?
Via the external microUSB connector. Every USB outlet in the world capable of providing at least 1A of current is suitable.
Why does Relio² still have a microUSB plug instead of the newer USB-C?
The answer is simple: maximum cable length and cord flexibiity. USB-C is born to transport a lot of data channels, so the internal wire count is 4x more, making it very thick and more rigid. For the same reason, USB-C cables lenght is limited to 2m. In the Relio² Base Kit package, we include 1x 1.5m magnetic, nylon-braided microUSB cable and 1x premium, gold-plated, nylon-braided 3m microUSB cable from a premium brand.
Can I use USB-C to USB-A, or USB-C to microUSB adapters?
Yes, of course.
Is the magnetic cable user-replaceable?
Yes. Contact us for a suitable replacement.
What if I use Relio² a lot and some parts wear out?
We engineered all the Relio² parts subject to normal-use wear and tear to be of common availability. Contact us for suitable replacements.
Does it have a manufacturer warranty? What does it cover?
We offer 2 years of manufacturer warranty on our terms of use and warranty. Please consult our sales terms for details.
How much power does Relio² draw?
1A at 5V DC. Since it integrates a step-down buck converter capable of up to 15V DC, power consumption at higher voltages will be less.
Can I power it up with a car battery or other sources of electricity?
Yes. Every source ranging from 4 to 15V DC is suitable. Input lines are protected from overvoltage and reverse bias. For more info, please consult the manual or our technical specifications.
Is it water resistant?
Yes, moderately up to IP53. For more info, please consult the manual or our technical specifications.
