Heating HDPE and Safety Answered


I have a light and am bothered by the glare below the shade.

I have cut a piece of HDPE from a plastic milk bottle and have slipped the section below the bottom of the bulb (60 Watt  - 75 Watt bulbs) ca. 1 inch below, and the bottom of the  lamp shade.. There are gaps between the plastic and shade to allow heat dispersal.

I have noticed that the HDPE gets quite warm, but looks and feels alright.

I am concerned about any possible toxic emissions, ethylene gas (no smell) etc.

Can anyone advise regarding safety?



As long as the plastic isn't changing colour, you're fine.
