RE: [AGA-Member] tank lighting--light pipes?

["Steven Blumenau" <steve@blumenau-family.com>]

What is described below is very much like a deck prism. This was used
in ships to light up rooms below deck. They work very well. You can
still purchase them.

This other link has a very simple multi-sided lens collector that's 
intriguing, but I've no idea who could supply it, as this is from a 
design student.

What do other folks think of this general kind of system?
Thanks!

Subject: [AGA-Member] tank lighting--light pipes?

I don't know if folks would consider this somewhat or very off-topic, 
but it's a lighting design query.
Besides neglecting my tank horribly lately (various emergencies) I've 
been dealing with 100+ temps outside lately, which is making a different 
low heat-gain lighting system sound more and more attractive.
I've got some decent CFs going now, not even metal halides, but besides 
considering my electricity bill, various design issues make me itch 
about my setup.  (Some folks buy a new tank + gear when they feel that way.)
I realize that a lot of folks (not everybody) says sunlight is a bad 
light source for tanks, directly through windows.
But I've been looking longingly at fiber optics for a long time. (I 
think I posted some queries about it to AGA some time ago.)
I found two recent postings on treehugger about lighting otherwise dim 
interiors (compensating for bad building design, usually.)
The wbsite treehugger is a collection of links to speculative and green 
product sites attempting to make various forms of conservation more 
practical.  http://www.treehugger.com/index.php
One link went to this company, which says its light pipes can bring in 
4000 lux.  Obviously that would depend on your outside source.  Umm, 
aside from a minor problem that we get non-tropical # of daylit hours 
problem, *we* get such bleachingly intense sun that you could filter 
down to almost any level of intensity.
http://www.parans.com/products.htm  There's a specs sheet as well on a 
link there.
