 By Dan from Milwaukee, WI on December 10, 2012 Can the dimmer mechanism be separated from the plate, or is the plate and dimmer manufactured as a solid unit?
I already have a Lutron plate and would simply like to install the dimmer.
By Jacob from Pegasus Lighting on December 10, 2012Answer:Dan,
The wall plate picture is NOT included, so you would only be purchasing the actual dimmer switch.By Jim Hodges from Houston, Texas on September 13, 2012 I have a WAC Lighting rail system that uses an electronic transformer. There are five 12V MR16-G 50 Watt bulbs on the rail. The instructions say "if dimming, an electronic low voltage dimmer is recommended". Is this the correct dimmer for my application? By Jacob from Pegasus Lighting on September 13, 2012Answer:Jim,
Yes, this dimmer is correct for your application - as long as the rail system is the only fixture connected to the dimmer. If you are connecting any additional lights, you will need a higher load.
Good luck!By Cedric from Longmont, CO on September 13, 2012Answer:This dimmer is definitely suitable for your application, this specific dimmer (as any other Lutron ELV dimmer) is specifically designed for working with electronic low voltage transformers (needed for MR16). My company produces an LED MR16 module for OEM manufacturers and I bought specifically these dimmers for tests and trade shows for illustration of compatibility. The Diva is a great product.By Christopher from Lafayette, CA on January 31, 2013 Can I use this dimmer to control a Low voltage transformer circuit plus a circuit with regular line voltage lights or do I need to control them with separate dimmers? By Jacob from Pegasus Lighting on February 1, 2013Answer:Christopher,
I would use separate dimmers...
an ELV dimmer for your electronic transformer
a line voltage dimmer for the line voltage lights

Lutron Dimmer for Low Voltage Transformer
February 19, 2013
The dimmer is great - just expensive! Works like all other Lutron DIVA dimmers I've used. ONE IMPORTANT NOTE: the dimmer requires a neutral wire. Most "normal" dimmers do not need a neutral to operate, and many residences do not have a neutral in the typical wall box wiring setup used in most rooms. NO NOTE of this is made in the Pegasus description or in the Lutron info. I learned this only after getting the unit and reading the install instructions! DIY'ers beware! No neutral means pulling a new wire to the wall box which could mean opening up the wall. I was powering my cabinet light install from an outlet circuit with the source right near the dimmer wall box location, so I had no problems. Something to consider...
Merchant Response:On our Specifications & Measurements tab we have a wiring diagram showing the neutral wire connection for this dimmer. We will also add a note about the neutral wire to the Description tab for this product page. Thanks!
Pros:Works very well - acts like all other Lutron dimmers.
Cons:Expensive! Also, a neutral is required, a requirement not made obvious in any web documentation. That should be fixed.
