Building a UVB/D3 sunbed

I know vanity sunbed shops are everywhere but these are mainly UVA light and useless for D3 production.

I'm thinking of getting some fluorescent light fittings and reptile 10%+ UVB tubes (E.g. http://www.reptiles.swelluk.com/reptile-supplies/reptile-lighting-415/reptile-uv-bulb-lamps-562/arcadia-d3-reptile-lamp-t5-12-uvb-282650.html) and making my own solution.

Those UVB psoriasis lights are crazily expensive for what they are, so it will be interesting to see how well this works. Summer's finally arrived in the UK so I'm making the most of the real thing for now, this was a random idea bought on while sun bathing :-D

17kW on a three phase supply! I am talking about approx 100W of lighting, used at a reasonable distance and for a sensible amount of time.

http://www.arcadia-uk.info/userfiles/D3_reptile-_spd2.gif 12% UVB for the synthesis of vitamin D3 • Full spectrum lamp • Produces excellent natural colours As a full spectrum lamp, the Arcadia D3+ Reptile lamp simulates sunlight. This provides good colour rendering for viewing the vivid colours of your reptiles and their environment. The colour temperature of 7,500K approximates the mix of direct and indirect light from a bright, cloud free sky. It's 'just' UVA and UVB. UVC is the nastiest one. The study doesn't even say what wavelength was used. Commercial sunbeds are rated at

Any idea what the spectrum chart looks like? This doesn't sound like a healthy idea for a non-bearded dragon. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC79671/

I would add redlight or incandescent lights. When you get UV from the sun to get vitamin D, the red light component of the sun protects you from the damaging aspect of UV to some degree.

The color temperature of 7500K suggests it has less red than the sun. The lower the color temperature, typically the more red it has.

Let us know how it goes!
