Does your A19 Bulbs coated with Teflon?

Many shatterproof light bulbs are coated with Teflon (PTFE), which can harm pets such as birds. Can you confirm whether you use potentially harmful coatings on your A19 bulbs? 

We can confirm that our lamps are made of polycarbonate material rather than glass or Teflon. 

As such, there should be no extra coatings on the material or any concerns that might arise from the use of such materials.
