    I did see that again where the big sacs were present in different kinds of Phelsuma. I would sometimes see metabolic bone disease in the adults and more frequently the offspring. One P. standingi hatchling hatched out and quickly developed rubber jaw. I have not seen any Phelsuma come back from that once it starts. Sometimes eggs would not hatch at all.

    The differences are no more growth in sacs and improved breeding success once the full spectrum lighting was installed. I also don't see any more metabolic bone disease.

    I am presently using the reptile compact florescents from Catalina Island who is local to me here in the Sacramento area. Others are under run of the mill T8 florescents. Good bright light seems to be key to their metabolism, and some additionally apparently need full-spectrum lighting.

    Hope that helps!

    Very interesting. Could you please specify what full-spectrum light is? Right now I have one linear flourescent lamp 5%UVB and one compact bulb 5% from exoterra. Exoterra also have 2% compact bulbs, and these they call full spectrum, which makes me wonder if the 5% bulbs are also full spectrum or not... What should one look for if one wants a full spectrum light?

    hi, I am going to try to answer your question about full spectrum lighting.
    uvb 5 tube produces uv but at a loss of light intensity. uvb 2 tube produces very little uv but a far higher light intensity.

    full spectrum is in relation to how well it matches the light as seen in natural sunlight conditions, ie how we see colours with our own eyes in natural light.
    Natural sunlight has a Colouring Rendering Index (CRI) of 100. any artifical light that has a CRI of 95 or above is a full spectrum light. It is able to light up a object as it would appear under natural light. Relative to this is the Colour temperature. Standard average for sunlight is 5600K.

    so you need a light source that has a high CRI and a colour temp of about 6000k. for a tube to produce UV the colour intensity is lost, the more UV produced the higher the loss of light intensity.

    To explain it all fully would take pages and pages of writing so for ease what you need is a UVb tube for the UV and a 2% Tube for the high intensity. JUst a UVB tube alone will never produce enougth actual light. A 2% tube is a full spectrum tube.

    Hope this helps
