Here's the user manual of the photocell:

Sorry, by email I told you 6V and it seems to be 12V. Just go with the PDF and your photocell to the electrical store and they will help you better.

In the past we used batteries to power Chronopic. Now we don't do because it's USB, but you may solve this with something similar as you can see at right part of the image:

Hi,

I bought the batteries and it works fine.

Now the only cables I use are for data transmission. Nowadays bluetooth is connected to virtually every product, and I was wondering if anyone has found a bluetooth system we could connect so to avoid the cables. Also, I guess it should be coupled to the chronopic in order to function well. Anyone ?
