Research Project
An important consideration for the display chamber was lighting. LEDs were the optimum choice due to the low operating temperature. However, in order to have the intensity of light that was required to light up the tracks, it would take such a high number of LEDs that it became impractical.

Up to this point a traditional slide projector was used, aimed into the tank. This was very effective since the unit has it's own cooling system running a focused 150W halogen light. When spot halogen lights were tested to replicate this, the heat generated was far too intense, it in fact melted the side of the test chamber (reptile tank).

An energy efficient compact fluourescent spot light was tried as they run at a much lower temperature. Unfortunately, though not surprisingly, it was not bright enough.

The last avenue to be explored was using a set of xenon car headlight bulbs. Unfortunately, these bulbs require 20 Amps and since they would be required to run for up to 6 hours, it makes it difficult to find an adequate power supply. This has yet to be resolved. The ventilated box has been built for them but they have not yet been properly tested.
