![]() No seriously, they're just a very clever design (multi faceted) that reflect more light into the tank than other reflectors. There is an analysis here: http://www.advancedaquarist.com/issu...03/feature.htm The only thing is they are very large. There is a "miniature" design though that is a little less obtrusive. Do a search (here or RC or where-ever) on "lumenarc" (note that I think it's spelled with an 'e' not an 'i' - in case you don't find too many results try alternating the spelling. Some people may even be using two words, i.e., "lumen arc" so try that as well) and you should see some threads with discussions and/or pictures. http://www.pacificgardensupply.com/products.asp?cat=2 Click on the photo for "Lumenarc III" to see a view of the underside.
