I've been running one 24x7 for a couple of weeks - not quite pushing the envelope of unlimited but no signs of any issues so far.
I have just completed a 6 tube clock using them though I only have one tube so will be having some trick photography done this weekend to show what it would look like fully loaded - the recipient of the clock has hs tubes waiting!
I also took one of their colon towers which are nicely made.
The tube is available in both Z568M compliant base and their own proprietary base which consists of two rows of 0.1" pitch male headers (like the ZIN18 - although I see that is now available in an IN-18 compliant format).
I found some nice 'pin sockets' that are press fit into a PCB and work well on a 0.1" pitch - my only 'complaint' being that the base of the colon towers cannot sit flush against the PCB because of the plastic carrier for the 0.1" pitch pins though I expect that this can be pulled off.
I used the Z568M tube base so that other tubes with the same base could also be used.
The Millclock colon towers do not support any under tube lighting so, for a different board, I have come up with a solution for under lit colon towers that will match the base of the black or silver versions of tubes from Dalibor and Millclock.
