That would be 95% of the rated lamp voltage compared to actual voltage at the socket. Many things affect the actual voltage at the socket. Also 95% voltage is 86% intensity and the color temperature drops about 1500 degrees. To calculate try http://www.ushio.com/support/LampLifecalculator.phpIf you really want better lamp life setting the max at 95% would ~ double the lamp life, and that is actually scientifically proven.
Yup, so if it's off for a scene or a couple songs preheating is pretty pointless.And cools down to almost stone cold within a few minutes. We know this because of lamp temp measurements and inrush current evaluations done as part of product development.

Some background - our building is a concrete box. In the winter the heat is set to a toasty 60 degrees F in the auditorium - which typically means it is colder in the fly space above the stage as there are no registers for HVAC there. We used to have bats hibernate up in our fly space until we had the roof redone.

I'm willing to bet...not that many, since every Sensor rack requires factory-authorized commissioning. And incoming line voltage is displayed right on the CEM, provided one knows where to look. @DavidNorth , @STEVETERRY , et al; Is measuring socket voltage part of the turn-on of a Sensor rack?... I wonder how many installs with tapped up feeds have been replaced by an unknowing user with Sensors and 115 volt lamps ...
Re-check your math. coltemp/COLTEMP = (volts/VOLTS)^0.42and the color temperature drops about 1500 degrees.
Read calculatir wrong - 3050 becomes 2542 at 95% voltage.That would be 95% of the rated lamp voltage compared to actual voltage at the socket. Many things affect the actual voltage at the socket.
