Talk:Light tube

message: Should we perhaps mention that the light tubes in the Berlin metro station (in the picture shown) costed a fortune and were mostly inneffective as light sources? SaintCahier 22:34, 6 September 2006 (UTC)
replies: text: On my return from vacation, I found the pictures which were added to the article. Now, I´ve found (and integrated into the article) a reference for that installation in Berlin, but I have so far not been able to find details such as costs, effectivity, and even date of construction of that system. If your statement is supported by a reference, I guess we could write something of the sorts.--Chris Howard 22:31, 18 September 2006 (UTC)

message: Just wanted to note that the two part caption is excellent, where the top photo says "as seen from above..." and the lower photo says "...and below".  Rarely seen on Wikipedia, where usually photos are islands and there's no effort to make the article look like a whole in this way.  Nice.  Tempshill (talk) 16:15, 27 December 2007 (UTC)

message: Well if say a building has a huge light source, can piped lighting be put to effective use there?  —Preceding unsigned comment added by 202.56.215.22 (talk) 12:38, 2 June 2009 (UTC)
thread_title:  can be used with real light source? 

message: *A more recently developed improvement to light tube technology is the Collimating Tubular Skylight, which adds a megaphone-shaped optical collimator to the top of the light tube to straighten out the solar rays entering the skylight above the roof.  This collimator improves the efficiency of the tubular skylight by minimizing the number of bounces the solar rays make before entering the room below. Since each bounce (reflection) involves a significant optical loss (typically 8% or more since the specular reflectivity is typically 92% or less), the throughput efficiency is much higher for the collimating tubular skylight.  When the light enters the room below, it is contained within a smaller angular region, providing better illumination in the workspace beneath the luminaire.  This technology is fully described in U.S. Patent 6,363,667 and at the web site of Entech Solar, Inc.
We need to have some independent, secondary sources to show this variation has any notability before we devote a whole section to it. See WP:NPOV, WP:V, WP:PSTS.   Will Beback  talk   10:04, 10 September 2010 (UTC)

This would be a useful addition (which I am afraid I have not the time to add). Robbiemorrison (talk) 17:06, 21 January 2013 (UTC)

message: TDDs appear to be one application of light tubes, and not one that merits a separate article, given the lack of strong sources. Ibadibam (talk) 18:10, 23 September 2014 (UTC)

text: Support (merge of "Tubular daylighting device" into "Light tube", as specified in the merge templates in these articles). --Chris Howard (talk) 19:21, 23 September 2014 (UTC)

text: Support merger. Sminthopsis84 (talk) 12:11, 24 September 2014 (UTC)

text: Support merger. It's really two names for the same thing, with TDD being perhaps more specific towards penetration through the roof of a building. Pontushammarback (talk) 23:30, 27 July 2016 (UTC)
