We've been working on small easily hidden away "grow light" systems and the brackets are a problem. There's simply no need for the new LEDs to "screw in" or "snap in" ~ for many of them it'd make more sense to just give us a flat plastic block where we'd use rubber glue or velcro tabs to affix them.
First off, I guess I'm having a problem with the terminology of: "bracket". That aside, if you can't deal with supplying "green" replacement bulbs, LED or otherwise, that a consumer can't screw into an existing - existing for close to 100 years - appliance, then you're going to have problems. Velcro or rubber cement, isn't going to cut it.
Yes, I can see the need for a new connection standard, but the world has been dealing with a very old, and in their mind, reliable standard for close to a century. If you can't be backward compatible, while promoting a newer standard, with no fuss or muss (and minimal cost) to the end user, you're going to lose.
Unless you want government to step in and mandate hope and change.
Oh wait...
Sorry about that last... sorta...
