Query: Film around bulbs melted!

I'm a full-time proofreader, so my work requires excellent lighting. I enjoyed using the 3M glare-reducing task light for the last three years: it definitely reduces eye strain and provides a very crisp and balanced light. I was completely satisfied until I started smelling burning plastic this week. The white film around the bulbs had melted! How long have I been unwittingly breathing in these fumes?! It's simply not worth the health risk to buy this lamp again.
