I’m working with a Lutron lighting system for a house that has 800 feet of LED. Each LED section is 6 feet and line the ceiling in all the rooms. The gentleman doing the programming for the lighting system is having a problem with adjacent LED fixtures where the dim levels are very different at 10%. We are using forward phase dimming through an RPM-4A dimming module. It's not that it is not dimming to 10%. It is that 10% looks different on adjacent Linear LED runs. The keypad controls are all low voltage separate from the 120V switch leg. The Lutron RPM-4A dimming module feed the QTran power supplies which feed the Linear LED strips. All of the QTran power supplies are using the same Tap. When he send’s a command to multiple LED switch legs to dim to 10%, the light output on adjacent LEDs is very different. Same Tap, Same dim level, different results. No error codes showing up on the Lutron RPM-4A dimming modules
We have tested the same exact Lutron system in our shop with 4 sections 8 feet long and it dims fine and equal. The power supply company has also tested the same system in their office with no problems.
The power supply company and the Lutron programmer are all blaming the LEDs. We have replaced a few and this does not fix the dimming issue.
The products they are using are as follows:
RPM-4A dimming module
QTran power supplies-QTM-DC+CAP 60 watt/100 watt/200 watt
Thanks in advance.
