What does “VFR” mean in Wheelock model numbers?

I’ve came across a lot of Wheelock products that have VFR in the model number, but I can’t seem to find any differences between the VFR models and the models that don’t have “VFR” in the model number. Anybody know what it means?

From what I could analyze, I was able to find the AS with the normal horizontal strobe mounted upward, however it’s VFR model has it mounted sideways instead. Also the MT-24-LSM normally has a completely clear strobe while it’s VFR model has a partially frosted strobe.

From a speaker strobe manual
V = vertical lense
F = FIRE lettering
R = Red plate
There are also white alarms with “VFW” suffix.

There’s also some not-so-common ceiling mount ones with a “CFW” suffix. (Ceiling, Fire, White)

Thank you everyone for the help!
