    Alright, so when we went to the reptile pet store- they sold us this bulb for $35. Being a minimum wage worker and college student, that seemed like a lot but we got it because they claimed "it's the best you can get at a pet store."

    How long are these bulbs supposed to last?

    Ours just broke- within two months the wiring it in disconnected itself and we don't have the reciept so we're not quite sure what to do. We could try bringing it into the store and see if they can return it.... doubtful. Or we could call the company maybe? I just don't know but we're not too happy.

    Now we have to buy a new bulb- we're not really into buying an expensive mega-ray offline. Or at least, my boyfriend is against it. =/

    What are the best longest uvb-producing lights you can purchase at a pet store? And how long, if we get another solar-glo, do they produce uvb for? Is it 6 months like most bulbs? Or since it's mercury vapor will it last us a year- granted it doesn't break.

    Exo-Terra Solar-Glo, 125W

    There's the link to the description from the store we purchased it from.


    This is for our Savannah Monitor, if that changes anything.
    Thanks for your help!

    Your best bet is to buy a mega ray, its the best in the business. I have had 2 solar glo's and ever since they started mass producing them in china they went to ****! Solar glos are good for 6 months but the UV they produce now is good for about a month if that. there was a lot of testing done to prove it. On the other hand the mega ray is the best and longest lasting bulb on the market. I have one on order now. They are on back order but should be in sometime this month. (These tests we not done by me. they were dome by Frances Baines)

    This lamp was operating at ONLY 115 watts - although 160W was stamped on the lamp itself, so it is not one that "got in the wrong box".

    Lamp 3:Sent by Rolf C Hagen in March 2010, stated to be "new product"
    Total UVB after 1hour (I have not burned-in this lamp):
    10 ins: 43 uW/cm2
    12 ins: 31 uW/cm2
    18 ins: 15 uW/cm2
    UV Index:
    10 ins: 0.8
    12 ins: 0.5
    18 ins: 0.2
    This lamp was operating at 159 watts.

    Spectra:
    The 125W lamp purchased by Dawn in October-November 2009 was presumably manufactured before the change in specs - it is very different - the only one with what I would describe as a "good" spectrum. It has no un-natural short-wavelength UVB below 295nm and a good spectrum for a mercury vapour lamp, with a small peak at 297nm and larger peaks at longer wavelengths still.
    None of the other lamps had any UVB below 300nm, in fact hardly anything below 313nm. This is why they give such very low readings with the meters, of course.

    I am about to write a full report for ExoTerra/Rolf C Hagen. I will be interested to hear their comments. These are very disappointing results. A high-quality UVB fluorescent tube such as an Arcadia D3+ 12% or a ZooMed Reptisun 10.0 tube can have a UV Index reading between 0.7 - 1.0 at 12" after burning-in -which is better than two of these mercury vapour lamps with the new specifications!

    But there is still Darren's lamp with the inner coating, unaccounted for... Maybe the company has discovered the problem already and the lamp Darren received is supposed to be a better replacement???
    I expect we'll know more soon...
