Source Four LED Series 2 Symbols in Vectorworks

I am new to using Vectorworks for lighting purposes, and I need some help with symbols and their meaning.

I know have have the Source 4 LED Series 2 Lustr+ fixtures. I know that Vectorworks lists these fixtures under sybmols "Light Instr ETC Source 4 LED2" along with the lens tube degree. I do not know what "LED2DS", "LED2LS", or "LED2TS" mean, however, and would appreciate some clarification. 

Some further helpful information: I am using Vectorworks Student Edition 2023. The fixtures are Source 4 LED Series 2 Lustr+; we use standard lenses and not EDLT or XDLT lenses.
