Oh boy, I think it's possible that the light one actually uses the reverse ordinal gemantric conversion instead of the regular one for some reason...and that reason is probably that I messed up and need to release a patch asap.
I have no idea how I could make so basic a mistake after hours of meticulously assembling this dang puzzle ... I'm super sorry about that... thank you for essentially playtesting it for me ... Your original combination seems to be correct, but try 1353 for light.
Again, sorry for the issue. I'd be happy to send along pdf copies or codes to my commercial tabletop games as an apology offer. Just let me know where it would be best to send them.
