i posted in this section about my beardie becoming lethargic and losing her appetite, several people said that it was probably the "reptiglo" uvb bulb i was using. I sent an email to exo terra to see what they had to say:
hi there,
i have had a bearded dragon for 9 months, for the first 6 months it was very healthy and ran around full of energy and eating tons of crickets etc. for the last 3 months it has become very lethargic, has lost its appetite to the point it will only eat about 3 crickets a week, and seems to have difficulty seeing its food unless you wave it in front of its face for 1 minute.
i posted in a bearded dragon forum explaining the problem and my setup, my temps, which vitamin supplements i was using, diet, and the basking lamp/uvb bulb.
Several people immediately said that it was the exo terra reptiglo 10 bulb, and that they hadnt been very good for a while now. I was skeptical because i thought exo terra was a good make, it was recommended to me by my local reptile shop, however i only had to google the words "reptiglo" and "lethargic" and "appetite" to find dozens of pages in forums of people complaining about their bearded dragons having lethargy, loss of appetite and eye problems from the reptiglo bulb.and that "It emits low wavelength UVB which is borderline UVC emissions."
I am shocked that a reputable company like yourselves is continuing to ignore this issue. Not only this but everytime i have bought a 75w basking tight beam bulb from you it has broken within 6-8 weeks.
I now have to change the uvb bulb to a zoo med reptisun bulb and hope that my beardie's appetite returns and its eye sight damage is not permanent.
I hope that you will look into this issue as it is a serious problem when thousands of people out there are using your uvb bulbs.

Dear Mr *******
Thank you for your e-mail.
The understanding of reptile lighting has continuously evolved over the past decade. Many studies have been conducted to determine the quantity and quality of ultraviolet lighting related to the animal’s metabolism. At Exo Terra we followed these developments closely in a continuous effort to provide the best possible products. Not only did our research and development team consult scientists and laboratories, but they actively went into the field to gather data on natural ultraviolet light in reptile-rich environments.
In the meantime, it has been proven that the race for the highest ultraviolet output amongst manufacturers was detrimental for captive retiles and that the “Exo Terra “less-is-more” approach was the right one. The details were published in our 2007 lighting guide available on the Exo Terra website: www.exo-terra.com
It is now known that one of the main areas of concern to do with UVB bulbs causing photo-kerato-conjunctivitis was the type of phosphors used in the bulbs. The use of “phototherapy” phosphors is of particular concern. As a result of this, in 2007 we implemented new phosphors in all our fluorescent lamps meeting today’s standards. These high grade phosphors, made in Japan, are composed and blended to obtain the optimal spectra for reptiles. We have not had any reports of problems with these Repti Glo 10.0 bulbs.
Other factors to consider include how close the UVB bulb is to the animal. Obviously, the closer the animal is to the bulb, the more concentrated the effect of the UVB output will be, so do not place the UVB bulb very close to the top of the basking spot. Reflectors will concentrate the effects of the UVB bulb, while placing them outside of a terrarium screen will filter out some of the UVB.
UVB bulbs are not very bright by nature, in fact the higher the UVB output, the less visual light is emitted. This means there is nothing to discourage the reptile from staring at them, so by placing it in the same area as the basking light, this gives a bright light source from that direction, which will discourage the animal from looking directly at the UV light source.
I can assure you that Exo Terra UV bulbs have never caused this problem and they have been tested by our reptile experts at our laborities in Canada. In fact there's not thousands of people using our bulbs but millions, being the brand leader.
This problem was with another companies bulbs, NOT Exo Terra.

im just wondering what people's thoughts are on this? are there many people that have had problems with this bulb? are exo terra just ignoring everyone moaning about it?
