Why are the Edison screws allowed to be used? They seem unsafe. Why are they designed that way?
They require a complete grounding system to ground devices for the rare situation where the hot wires somehow touches the metal case of the device
While they let you use a lamp fixture which has an exposed hot contact when you remove the lamp, and nothing is there to protect your finger from touching it.
I would expect this socket to have a different design which will cover the contact from accidental touch.
Here's your opportunity. The market's looking for that right now so build a better mousetrap.
The USDOE and California CEC want to murder the Edison base to finally stop people from using incandescent bulbs, and enable fixture designs that don't have to worry so much about dissipating heat. They mandated GU24 in 2008, which solves some of your concerns. Take a look at how that's going 8 years later. LOL.
There are several flaws in the GU24 that you should address in your new design.
