Hey all, maybe you can help me out with this: I'm working at an older summer stock and the bulk of their inventory is old LEE Colortrans and some altman 360 radials. In the colortrans for some reason they're using HX-601's and for the radials they have HPL 500's. The current lighting designer and myself have discovered neither of these lamps work efficiently in the instruments. The new version of the HPL lamp is shorter so it doesnt go all the way into the reflector of the radial. We think we're having a similar problem with the colortrans because their light output is horrific. Short of buying new instruments, any suggestion of what kind of lamp to buy that will remedy this efficiency problem? We're looking for something in the 500W range for the radials and a 575W replacement for the HX's? Thanks in advance!
