What's the main diffrences between the S4 and the S4 jnr apart from the size?
Source 4 and Source 4 jnr
- Thread starterMadferit101
- Start date
Standard S4 ellipsoidal:
- 750 watt lamp capable
- Rotational front lens and shutter section, so better ability to do odd shutter cuts, rotate gobo image
- Interchangable lens tubes, 5 deg. thru 90.
- Standard A & B size gobo's
You lose those features in the Jr. though in the Jr. you can interchange different degree lenses. The Jr. also uses the M size gobo which is an odd size.

Jr's cannot take a 750w lamp like the full-size units can. Even at 575w, a Jr is slightly inferior optically to a full-size and will not be as bright as a 575w full-size. I've used Jr's frequently in a theater where all the full-size units they have are also lamped at 575w. Can't say the difference in brightness has ever been an issue that'd be apparent to anyone but me.
Biggest problem I have with Jr's when I use them is that the gobo's are M-sized, and inability to rotate the barrel. Even without gobo's, not being able to rotate the barrel makes it impossible sometimes to get the shutters to cut on the angles you want them to.
There are certainly good applications for Jr's -- just make sure if you use gobos a lot that need to be properly rotated to work, or if you need precision shutter cuts that you have full-size units around for that.

Source Four 450, 436, 426, 419: MSRP $440.00 US.
Source Four 450J, 436J, 426J: MSRP $278 US.
So the junior is 63% of a full-size (senior).

If I was buying juniors I would buy zooms unless I knew for sure I would only use it at one location.

Derek, you're paying too much for your lights. 
Also notable is that ETC isn't releasing an LED version of the Source Four Jr (although they have released an LED version of the Mini.) The Junior is notably smaller and lighter than the full-size Source Four, which occasionally makes it handy to sneak into odd/difficult locations. The lighter weight also makes them a little easier to work with high school and middle-school kids.
Perhaps as a result of the smaller size, I find the Juniors run a lot hotter (to the touch) than their full-size cousins. I've also seena lot more Juniors with the paint flaked off than full-size, outside of architectural situations.

There are multiple rotators available for the junior.

They do partially address the gobo rotation issues with the design of the gobo holder that can spin a few degrees inside the slot.

Cheers! It's much appreciated.
