Non ATX things

b) Pendants  - you will notice on Wayfair, Houz, etc,  that these have one of the following specs  E26, E12 or GU10.  
    Any of those are supported without any need for discussion
    more info:  pendant or sconce fixtures?

c) Outdoor - same as Pendants.    Non- E26/GU10 fixtures in use today for example are shown here:

e) UnderCabinet - EL provides excellent strip light solutions used for UC, or you can let us know what your cabinet maker prefers.

f) Track lights - GU10 are in stock

g) Vanity - there are two types.    E26/E12 Vanities, and Integrated LED Vanities.   E26/E12 are trivial, 
    Integrated LED require ATX LED to review or modify

h) Chandeliers - same discussion as E26/E12.   The only difference is that because of the weight and number of bulbs, we prefer different mounting hardware and that you let us know the likely location for them.    More info:  chandeliers

i) Exotic custom things only available in 120vac.    We can imagine that art and style might be embodied in a high end fixture that are 120vac and best used as is.    The 62386 ( DALI ) bus which is central to our smart installations, have products from multiple vendors for legacy 120 vac fixtures, with dimming, so there is no issue.
