I've been searching the internet for this answer for a while and couldn't seem to find it. Could anyone tell me what the weights for these lights are: Source 4's Source 4 Jr. Zoom's Fresnel's Altman's I would like to find out so that I can post it somewhere in my theatre. That way, when we hang lights and have to reweight battens it will take a little bit of the guess work out of it. Because for some reason, none of us know how much they weigh. Thanks.
