Does installing these things violate the NEC?

410.90 Screw Shell Type.
Lampholders of the screw shell type shall be installed for use as lampholders only. Where supplied by a circuit having a grounded conductor, the grounded conductor shall be connected to the screw shell.

IMO it would be a violation of the NEC, regardless of whether the device is listed or not.

I have seen these before, but today I was shopping on Ebay and they were all over the place......Just because somebody makes them and lists them doesn't mean they are legal to install per the NEC.....

I totally agree.

I would say that if you installed a lampholder for the purpose of installing this smoke detector, then it would be a violation of NEC. However, if a home owner installed one of these into an existing lamp holder to augment their fire protection, then it is not a violation of the NEC.

If it violates the NEC, how 'bout a Code Article?

I can't find a durn thing about resi smokies in it.

This is the section I think it violates.

I can see both sides as the lampholder is also powering a supplemental device. Until this post I always thought that it meant that the screw in receptacle adapters were not to be used.

That section (IMO) only applies to the installation of the screw shell, and we all know that when you installed it you intended its use as only a lampholder. Right?

What the customer screws into that lampholder after your job is done is arguably beyond the NEC's reach.

This is another one of them things that nec thaught they covered to stop the use of screw in recetacles. Screw in receptacles have been around for many years. Yes as written it violates nec but who will stop it ? If they help why not leave them alone.
