etc source 4 led2ls vs etc source 4 led2ts

[SteveMcQueen]

Looking at the correct Vectorworks symbols, and I have etc source 4 led2ls and etc source 4 led2ts. What is the difference?

Just guessing here, but maybe ls is lustr source and ts is tungsten source? I think the 2nd gen fixtures still had the option of getting one with a 3000k light engine.
