Has anyone out there run into the Solais LR38 dimmable LED lamp? A high school I work at just replaced all of the incandescent lamps in the house light fixtures with these LED lamps. The fixtures are fed by ETC D20 Sensor dimmers controlled by a CEM Classic (five fixtures per dimmer). No adjustments were made to the dimmer settings at the time of installation. Their dimming performance is subsequently not very good. Solais provides recommended dimmer settings but they do not seem to be applicable to the CEM Classic we have installed in our rack. I'm not even sure if the settings are applicable to the CEM+. I don't see any mention of "LED Smoothing Forward Phase" mode in the CEM+ manual. Does anyone have any experience with getting dimmable LED retrofits like these to work with an older Sensor system? I tried switching the dimmers to a linear curve with a 5% threshold but it didn't seem to make much of a difference in performance. With a 4 second fade up from the Unison system the fixtures snap on with a bit of flickering before they begin to fade smoothly They are similar but not as bad when they are fading out. The ultimate question for the near future of this system will be whether it makes sense to replace the CEM with one that can handle the control requirements of these lamps, or to just switch the fixtures back over to incandescent lamps.
