Does anyone know what has changed in the rigid industries e series light bars through the years? Diodes, reflectors, drivers, etc... the reason I ask is I can get an older one for cheaper than a new one and I'm wondering how much better a new one is vs an older one. Thanks.

 

Check out this thread. Rigid has made numerous changes to their bars, but be sure you are comparing an E to an E and not an E2 or something.
