Will these lights melt?

As long as you don’t close the barndoors on the lights while they are on, they should be able to handle any lighting situations. We have confirmed this through expensive long term testing, as well as with thermo camera information showing the heat the lightbulbs produce.

What happens if I left the light on with the barn doors closed, will they melt?

They will not melt, but they may get hot enough to hit the glass transition point of the PETG plastic. This means the barndoor may get soft and lose it’s perfectly flat form.

What can I do if I warped my barndoor?

If you want to fix it yourself, you can heat it up with a hair dryer, and when it get soft, compress it with some heavy books ideally with parchment paper as a barrier. This should allow you to achieve a fairly flat repair. This should fix it functionally, but it may bare some cosmetic evidence of the damage. If it is under warranty, a replacement can be provided, otherwise, if looks really matter, replacement parts are available for a very reasonable price.
