Arri Fresnels - How the heck do you open them up ?
 

I'm a bit embarrassed to post this, but, here goes.

I just bought a couple of used small, Arri fresnels. There were no manuals with them and Arri's site doesn't have a manual posted.

How do I open them up to change the globes ? It's not at all straightforward like my Moles -- they have simple, spring-loaded release knobs.

Thanks for any assistance you can offer.

On the 150's you undo a screw at the back and the lamp holder slides out. On the 300's and 650's there is a section of the side that is held closed with a spring clip. It opens like a flap to reveal the lamp and holder.

Yep. That's the ticket !

Thanks...
