Regarding the Able Laser AB-IV and AB-III models I spoke with the CDRH and they have informed me that the lasers are legal and compliant. See below
"Hello Mr. Dickson,
I apologize for the delay in responding to your question. I was not able to do so because of the shutdown.
The firm Quangzhou Able Laser, aka Guangzhou Able Entertainment Lighting, does have the variance you identified. It was issued in 2010 and has been renewed each year since. So it is currently in effect.
The variance explicitly mentions their model family AB-IV, but it permits them to add additional Class IIIb or IV models to their list of models. The AB-III model family is such an addition and so is certifiable under the variance. There are restrictions on the effects the models may produce, specifically including no audience scanning or exposures.
The projector should have a certification statement on it, either in a separate label or combined with the firm’s identification label.
I hope this answers your concerns. If you have any more questions, feel free to ask me.
Sincerely yours,
Dale Smith, CSO
