Can anyone explain what the difference is between the old white label RPM-4Us and the new red label RPM-4Us?
A while back I spoke to someone in tech support about the dimming triac changing about 10 years ago. But what I really need to know is ...How critical is it to swap them out? I'm servicing a 9 Panel system, and speaking with the client about a QS Upgrade, but if the RPMs absolutely have to be swapped as well there's no way the client will upgrade. It doubles the price from about $40K to $80K.
Also spoke to the client about LEDs, and they have no intention of swapping any lamps out at this time.
Any info would be helpful.
Thanks
