A corporate perspective (Ellipsoidal): The article on Ellipsoidal theatrical spotlights is quite accurate from a USA perspective, however, it has a slight bias towards the ETC company, which is justifiable, given their innovations. Rather than state that the particular product is the most popular, which might be true, it might be more appropriate to state that theirs was one of, or, the first developed in USA, to use the glass reflector, which allowed much of the infra-red energy (heat) to escape back through the reflector so that mainly visible light was reflected forward, keeping the shutters, iris, gobos, lenses and filter material cooler, with obvious benefits in terms of life. If I remember correctly, there was a European company with glass reflector spotlight years before ETC. My feeling is that product descriptions should be free of corporate promotion, but with a link to the corporation, so that interested persons can find out where to buy same, with a second click. The idea is to be as objective as possible.
The term 'ellipsoidal' is unknown to me. It appears to be what I know as a profile in the UK. ColinFine 00:48, 5 February 2006 (UTC)
I think the Re-invetion section comes off as very POV, but I don't know quite what to do about it. - JWGreen 16:56, 21 February 2007 (UTC)
i dont think that the noted bias toward ETC is to underserved as most theaters (almost all) and many large stores and other business use almost solely ETC Source Four products. they have really come to dominate the market. just saying —Preceding

COI warning Full disclosure, I worked (as a subcontractor) on the process I am about to describe for at least two of the companies mentioned in the article.
There is only a passing mention, but one of the "neat" characteristics of these lights is the application of a thin film (through vacuum coating operations) that draws the heat of the lamp through the back of the lensreflector, significantly reducing the heat thrown into the performance area, i.e. keeping the stage cooler. Could/should it be added?
