1. What exactly is included in the scope of delivery?

To avoid transport damage, we send the TWORBALL in a shipping box padded with foam. In addition to the TWORBALL, the following accessories are included in the scope of delivery:

1. Satin fabric bag (for transport and storage)
2. Radio remote control
3. USB charging cable
4. Printed manual (D/E)


If you order the TWORBALL with a magnet holder, there is also a magnet with a threaded rod (according to your specifications) in the scope of delivery. If you order the TWORBALL with a rotation tool, the tailor-made rotation tool (finger loop with wire rope and snap hook) is also included in the scope of delivery. You can find more information under "Variants".

2. Which variant is right for me?

The preferred methods for turning the TWORBALL are as individual as we humans are. While some use a jump rope from the sports shop, others use a self-constructed pole tool. The complete set including rotation tool that we offer is also very popular with beginners, amateurs and professionals. We offer every light painter the right solution for him. If your desired configuration is not there, please contact us and we will find your solution together.


The question of the "best" variant and method cannot be answered across the board. For undecided beginners, we generally recommend our complete set including the rotation tool. This set offers you a complete and proven equipment to get familiar with light painting. So you still have the opportunity to develop your own creative method for spinning the TWORBALL at a later point in time. You can find more information under "Variants".

3. What do I have to consider when using the "Registered" shipping method?

The shipping method has no influence on the packaging, we always send the TWORBALL the same way. With the shipping method "registered" a maximum of 1 TWORBALL can be sent, with the other shipping methods 2 TWORBALL can be sent in one package. Insurance is limited to CHF 150 if the shipping method is "registered". If there is damage or loss on the way, the transport company will reimburse you a maximum of CHF 150. You can find more information about shipping options and costs under "Order".

4. I have lost my manual. Is it available for download?

No, the manual is not available for download. Please write us a message using the contact form.

5. Is there an app for operating the TWORBALL?

When developing the TWORBALL, we made a conscious decision to use a radio remote control. An app would require a switched on mobile phone display during the shoot, which could possibly be seen on your photo. The radio remote control is ideal for the TWORBALL because, unlike infrared, it does not require a line of sight and works very reliably. There is therefore no app available for the TWORBALL.

6. Where can I order accessories (remote control, battery replacement,...) for the TWORBALL?

Please write us a message using the contact form and let us know which accessories you would like to order.

7. What delivery time do I have to expect?

The TWORBALL is not a mass product, but is made for you after receipt of payment according to your requirements in our factory according to high quality standards. We will inform you of the current delivery time in the order confirmation following your order.

8. What does the ordering process look like?

9. What exactly is the PWM effect?

A little excursion into technology: The abbreviation PWM means "Pulse Width Modulation". Nowadays, most LEDs are controlled with pulse width modulation and the user can adjust the brightness. The LED is continuously switched on and off again at a high frequency. If the duration of the status "switched on" and "switched off" is the same, the human eye perceives this as 50% brightness. The desired brightness can be generated by changing the relationship between the "switched on" and "switched off" status. Since the human eye is too sluggish, people do not perceive the rapid switching on and off of the LED as flashing, instead the LED looks dimmed. The advantages of this control are, among other things, a minimal need for electronic components as well as the avoidance of energy losses through series resistors (heat loss).


What does that have to do with the TWORBALL? What the human eye does not perceive becomes visible with light painting. The continuous switching on and off of the LEDs results in dashed lines in the photo when tools with PWM control are used. A process was developed for the TWORBALL to regulate the brightness of the LEDs without pulse width modulation. If dashed lines are still desired in the photo, they can be generated with the TWORBALL with the PWM simulator (strobe effect) in 16 different frequencies.
