I recently purchased a 5x7 zone VI cold light head for my DeVere 504 (don't ask but it works) - it arrived with a shattered bulb since the nice gentleman from ebay thought it would be a good idea to pack the box with bits of newspaper - anyway- i'm trying to get the darned thing OPEN just to take some shots etc but so far it's kind of confounding me - it would appear the frosted glass diffuser is mounted to a kind of steel flap that opens but no amount of pressing prying wiggling pulling or pushing is getting me there - nor can i find any reference to bulb maintenance in the instruction manuals i've found online.

anyone here know how to do this????
