I have been doing a lot of research on the Mega Ray both uv and non UV. The
http://www.reptileuv.com/ has a lot of information on lighting and its setup. The thing to remember is "lighting is a process, not a bulb". You will need two dome lights. For one of them you will need a 50 watt Halogen bulb or greater that puts out 4,000 lumens. Depending on the distance from the face of the bulb to your Beardie you may need a higher watt bulb. Remember that Watts = Heat put out. In the second dome light you will need Mega Ray Self-ballasted 100 watt MVB/UVB or Mega-Ray External Ballasted Kits 60 watt Flood UVB Lamp Kit or T- Rex Active UVB Self-ballasted MVB. Either one of these are a great choice for a 40 gallon Breeder. Third is a Full Spectrum Fluorescent that can put out at least 5,000 lumens. All of the lights should be on timers to come on at different times during a 12 hour cycle. First the halogen between 7-8 am to 7-8pm. Next use the Mega Ray or T- Rex between 9-10am to 5-6pm. Then use the Fluorescent between 10 -11am to 3-4pm. And what this does is gives your reptile a more nature sunrise to sunset simulation. This will create a healthier immune system and physiological well being. I hope this helps. And like they say on
retileuv.com "lighting is a process, not a bulb".
