Helios 4 vs helios 5 light controller?

Whats the difference between Helios 4 and Helios 5 light controllers, the helios 5 uses a nema 6/15 and is $10 more, is the helios 5 a newer model replacing the Helios 4? All the specs look exactly the same. Does anyone know what the difference is in controllers?

I think i figured it out the helios 4 can use 120 and 240 volt, the helios 5 only use 240 with nema 6/15 plug.

Helios 5 is listed ETL tested for Commercial Applications - pretty much the lack of the universal receptacles. Look at the Helios 4 receptacles and they take either 120 or 240v plugs.

Lol you beat me to it. Yeah for commercial use they have to eliminate the ability for a dummy to plug a 120v item into the controllers 240v output.

Love my helios 4, zero issues with it so far.

Yeah basically the only thing in them to fail is the contactors unless it has the integrated timer and they use Allen Bradley contactors.
