I'm curious to know what the consensus view is regarding the future of lamp technology in the long term. Principally in regards to how efforts to use more energy efficient technology might effect the methods we, as theater lighting designers/stage electricians, use to produce the light we design our productions with. I'm thinking long term (like 20 years) I've heard rumors about bans on conventional halogen bulbs coming down the legislative pipe in the distant future. I know that the potential technologies that we might replace them with (LED, HMI/HEI) don't/cant talk the same way a S4 does. I'm currently advising one of the community groups that I work with about upgrading their systems. The options appear to be A) spend $2,500/4,000 on a used ETC express. or B) Go all out and spend $6K on an Element. My thinking is that it would make more sense to spend the 6K on the Element because when and if halogen bulbs go the way of the dodo, an Element would be better suited to deal with new types of fixtures then an express. Am I wrong?
