    Hello John,
    It is not recommended that you remove the plastic film, because the plastic film is used for protecting the screen.
    Hope this can help you.

    Hello D. DOyle,
    Thank you for writing in.
    This product is compatible with constant voltage not constant current and the LED is drived by constant current.
    Therefore, it is not suitable for using LED as output, otherwise the chip of the product will be burnt.
    If you adopts LED as the output, since there is protection with the product, the product will be OK in a short time, but it will also burn if connect with the LED for a long time.
    As your description, the chip of the product may be burnt.
    Hope this can help you.
    Best regards
