Aquarium with LED lighting. Freshwater aquarium lighting is commonly provided by screw-in incandescent bulbs, fluorescent tubes and LED lamps.Incandescent lighting is becoming less popular because it uses much more energy and produces more heat than the other lighting types. [1]
An aquarium's physical characteristics form another aspect of aquarium design. Size, lighting conditions, density of floating and rooted plants, placement of bog-wood, creation of caves or overhangs, type of substrate, and other factors (including an aquarium's positioning within a room) can all affect the behavior and survival of tank inhabitants.
This suggests that UV light detection is crucial for correct mate selection. [23] UV reflective colour patterns also enhance male attractiveness in guppies and three-spined sticklebacks. In experimental settings, female guppies spent significantly more time inspecting males with UV-reflective colouring than those with UV reflection blocked. [ 24 ]

This is similar to the situation in a hydrogen flame. Arc lamps made with ordinary light-hydrogen provide a very similar UV spectrum to deuterium, and have been used in UV spectroscopes. However, lamps using deuterium have a longer life span and an emissivity (intensity) at the far end of their UV range which is three to five times that of an ...
