There is one issue with that MNicolai. Unless the space is playing on keeping everything self contanded, until conventionals are gone by the waste side, no one would want to be in a space like that.
The issue is touring shows now travel, expecting things like dimmers and
conventional lighting. Having to re-program an entire show for a couple of spaces because they have nothing but LEDs would be a waste. Dimmers won't go away until the industry as a whole excepts all LEDs.
If someone were to go all
LED and no dimmers, that would mean they have something that no one else uses. All
LED houses also won't be excepted until most or all of the venues are that way. To do that would take an astronomical amount of money, that just about no space has, even high dollar ones.
Another big issue is rental houses. If you are an all
LED house, and you
call a rental
house, what happens when they don't have the types of LEDs you are looking for? There are some many versions, each with their own little quirks, issues, and differences in beam size,
power, amount of LEDs, color of LEDs,
etc etc. When someone calls a rental
house asking for conventionals, they are, for the most part, all the same. A
Source Four is a
Source Four. All
tungsten lamps have a
color temperature around 3000k,
gel from one light will work in another, same with gobos, for the most part. I can easily
gel a bunch of
Source Four and
360Q lekos with R60 and have them all look like R60. LEDs however color mix slightly different from
fixture to
fixture, even within the same company.
All
LED houses, despite the savings in
power,
gel, and replacement lamps, might in the long run end up costing you more money since no one wants to tour through there. Being different and trying to be efficient isn't always smart.
