Hello All I will shortly be constructing an Aluminium rack to house my current (and future chameleons) along the lines of forum member Joery's (attachment below) but in units of three with mesh cages instead (quite a project for the new year ). Within the enclosed lighting unit at the top, I intend to use a linear UV bulb running above all of the vivs, but for spotlights - rather than have individual reflectors with standard household bulbs - do you think it would be possible to use something like the Halogen 50w spotlight unit attached below. Would these be suitable as a spotlight (initially for Veiled's but perhaps with more species in time) or do they produce too little or too much heat? If so what kind of distance should these be mounted from the top of a mesh viv/basking area to be used safely? Also I note that some on forums have suggested that angled spotlights are more beneficial as they simulate the position of the sum in the sky much better than a bulb directly pointing down? However look forward to hearing from anyone who uses these or can offer advice on this.
