Relio² User Manual
Welcome to the family!
Here you can learn how to master your Relio² devices and unleash their full potential, by reading our step-by-step, fully illustrated guide.
Intended useRelio² is a high performance, ultra-high CRI LED light powered via USB.
It is conceived to be used as a portable or static illuminator, for domestic and professional use.
WarningDo not stare into the high-power beam, nor power-up the device without any lens installed. Do not activate the “Strobo Mode” if you are sensible to high-frequency light flashes. Do not use with wet hands or in damp environments. If operating conditions are not met, or you notice an unattended behaviour, stop using the light. Not suitable for use by children, as it contains small parts.
Relio² should be serviced by professionals only.
For further information, consult our sales terms.
Lamp module attachment
Relio² is equipped with a standard photographic UNC 1/4-20 socket. Just use your hand to mount, unmount and rotate the light module on its stand.
Do not overtighten the bolt, it's not necessary.
Main bolt assembly
The mounting bolt is equipped with two differently-sized o-rings. Place the smaller one is on bolt’s handle side, and the bigger one between the main rod and the light module.
Spare o-rings are included into the package.
Base plate overview
The Base plate is what allows Relio² to be mounted on desks, shelves, walls, ceilings and magnetic surfaces.
If your target surface is non-ferrous, you can use the four included metal washers to make it magnetic.
Use the slotted notch only for temporary installations, as it s not as stable as a fixed, magnetic attachment.
Base caps removal (1/2)
To free-up all the three slots on the Base plate, you have to uninstall the stainless-steel caps that cover them.
They’re secured with an o-ring. Just push from the bottom to expel. Be careful not to lose the o-ring.
Base caps removal (2/2)
Grab the freed-up cap from the top. Again, be careful not to lose the o-ring.
To reinstall, just follow the steps in reverse.
Base magnets removal
Neodymium magnets installed on the Base plate are very powerful. If you do not want them close to your professional equipment (mechanical hard-disks, reflex cameras, credit cards, etc.) you can remove them by using the hex key included into the package.
Warning! Neodymium magnets are very brittle. Be careful when removing them. Do it one at a time, and keep them very far away from eachother. If they crash together, they will break.
Main rod removal (1/2)
To swap the main square rod to a smaller or longer one, use the hex key included into the package.
Tighten securely, otherwise the rod will become loose.
Main rod removal (2/2)
Be also careful not to scratch the Base plate surface while performing a rod swap. If desired, use a soft cloth to shield the surface while detaching the rod.
Main rod swivel (1/4)
To add a second degree of rotational freedom, you can install a big o-ring between the Base plate and the rod. The additional o-ring is included into the package.
Main rod swivel (2/4)
After placing the o-ring inside the Base slot, start to screw the rod by hand while holding the rod screw with your finger.
Main rod swivel (3/4)
Tighten the rod by hand, stopping when you notice that the o-ring is starting to compress and oppose the rod rotation.
Main rod swivel (4/4)
With the o-ring installed, you’ll be able to swivel the rod by ±45º.
Desk counterweight (1/3)
To prepare your Desk kit for intallation, you have to start by installing the heavy stainless-steel counterweight on the medium-sized rod (the one with 3 holes) included in your Base kit.
Start by locating the very small o-ring included into your Desk kit package.
Desk counterweight (2/3)
Place this small o-ring around the counterweight’s thread, while keeping the assembly in a vertical position not to lose the o-ring.
Desk counterweight (3/3)
With the small o-ring in place, screw the counterweight into the medium rod.
Desk assembly (1/2)
Now take the main nut-and-bolt stainless-steel hinge that comes with your Desk kit package.
Install the long rod onto the Base plate, by firmly tightening the rod’s screw.
Assemble the two rods as shown in the picture, by taking care of placing all the three o-rings as shown in the picture.
Desk assembly (2/2)
Now tighten the nut-and-bolt hinge by hand.
Do not overtighten the hinge, as you’ll generate unnecessary strain on the o-rings. Tighten as much as it’s needed to keep the rods firmly in place.
Magnetic cable disconnect
To disconnect the magnetic cable, bend it by 45º and pull it away.
If you pull in a straight line instead, you’ll probably pull out the magnetic bit too.
Magnetic plug maintenance (1/2)
The magnetic cable and magnetic end bit are, indeed, magnetic.
If you work in dirty environment, the magnetic cable assembly may collect dust and become non-functional. Clean both ends with a dry brush to remove any trace of dust. If not enough, use compressed air (at moderate pressure).
Magnetic plug maintenance (2/2)
Do not clean the magnetic bit with water, solvents or chemicals.
Do not use the magnetic cable if you intend to use Relio² in dirty environments. Opt for a classic, fixed USB cable instead. A beautiful 3m nylon-braided fixed USB cable is included into the Base kit package.
Magnetic bit removal (1/2)
If you want to use a fixed USB cable, you have to remove the magnetic bit first.
With the magnetic cable assembly in place, start to wiggle the plug left and right.
The magnetic bit should become loose, so that you can pull it away.
Magnetic bit removal (2/2)
When the magnetic bit is removed, a standard microUSB socket is ready to host and standard USB plug.
Use only high-current USB cables, otherwise Relio² may malfunction or become less bright because it’s not getting enough power.
To swap the the lenses, unscrew the light module cap with the included hex key.
Do not overtighten the cap screws, as it’s unnecessary.
Do not touch the clear side of the lens, you may scratch it.
Place the new lens carefully in its slot, and align the cap so that you don't need any force to close it. If you notice that the cap does not align properly, do not force the assembly! Remove the cap and re-align the lens. If you force the assembly, you may damage the lens or the LED component.

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?
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?
Is it water resistant?
How many units can be operated through the smartphone App?
On iOS, we successfully tested up to 16 devices. On Android, it varies depending on the platform (around 5 units). Please note that aggregate brightness control function is still in development.
Can I develop a custom Bluetooth BLE application?
Yes. You can refer to our BLE API documentation. Please note that developing commercial applications is not permitted unless an explicit consent is received by us. Please contact us for more info.
I need assistance and documentation on how to operate Relio² via an external, wired microcontroller like the Arduino®.
We will provide you with full documentation on how to operate Relio² through logic-level signals. Please contact us for more info.
I need assistance in determining how many Relio² kits I need for my work.
We can do digital simulations tailored to your environment. Drop us a message via the contact form.
Do you ship worldwide?
Yes, with some limitations in some remote areas. If you don't see your Country listed in the shipping form, please contact us.
You said that the LED will be upgradeable. How will you handle that?
This is a commitment and we will honour it in case the technology advances. All the future LED upgrades will be backwards-compatible, so you'll be able to ship your Relio² kits back to us for the upgrade, for a minimal servicing fee.
Can I disassemble the LED and eletronics by myself?
Yes, and it's rather easy to do, but the warranty will be voided.
I accidentally damaged something in my unit. Are spare parts available for sale?
Yes, depending on stock availability. Please contact us and we will help you.
Do you sell physical versions of your 3D-printable accessories?
