Lighting
•
Not Digitally Signed
—The information contained within the lighting file meets the
requirements of Direct Drive lighting; however, it has not been verified that the information
is safe to use with the specified light. Use this file at your own risk.
•
Invalid
—The information contained within the lighting file is unusable because the data
does not meet the requirements of Direct Drive lighting, the data describing the light is not
in the proper syntax, or the digital signature has been altered.
In digitally signed lighting files, the current limit and duty cycle limit are encoded as part of the
signing process. The limits in signed lighting files are not human-readable. Modifying a signed
lighting file will invalidate the signature and render the file unusable.
