Whelen UPS64LX vs. UPS-188C

[cromwell]

Hi everybody!


I have these two strobe power supplies, one Whelen UPS64LX and one UPS-188C.


One I am going to trade away with a friend and one will I keep in my collection.


Now my question is, which one is more "rare" or have more value??


If I understand this right you can only change the flash-patterns on the UPS64LX and not on the UPS-188C.


But then again the UPS-188C has 8 outlets and the UPS64LX only four...


Which one would you guys keep ??

Obviously, keep the 8 head, but don't let it sit too long without being fired up or it will go bad, as most power supplies will do.

OK, how often should I at least activate it? Once a year?

the 188c also has diagnoctix and a higher power output

How often should I fire up my power supplies??


Now I am first thinking about my strobe lightbars (Whelen edge, 9m, model 8000, FS Jetstrobe).


For example:


If I would leave these strobe lightbars untouched for let´s say about 4-5 years, could then the power supplies have gone bad after that??
