You want to see some CFL UV Readings?

Well 2 26w Repti glow uvb bulb. By the time this cage is finished will be about the time to switch out lights

If your going to use compacts,imo it would be best to go with a 10.0, especially if your using dome fixtures.

The fixtures he shows reflect the light better... Tonight when i get home I will pull out a few things and take readings and pictures to compare the two fixtures using the same bulb.

Just for the record what UV reading do we want to see for chams?

Imo 20 at the bare minimum, as in at that point its time for a new bulb or fixture/ bulb upgrade. 40-50+ is what I shoot for.. There are members and even a "big name" breeder that keep their readings well above that... keep in mind, that our bulbs will never compare to what the sun puts out. That being said, keep plenty of foilage in your cage for your cham to get outta the heat and light if needed.
 
I use all 12% arcadia T5 bulbs on all my chameleons. I would never go back to T8 bulbs or compacts as just by adding these new lights I have seen a difference in the chams!
 
My wiedersheimi serreta and perreti enclosures have been using the exo terra 10.0 with a perching area 5" below my light with the standard exoterra screen top for the glass enclosure. I would really like to know what the UVB reading is at that distance. If someone here had the capability to get that reading that would be fantastic. I think the time has come to invest in a meter.

Those exo terra bulb numbers seem quite low, disappointingly low.

Being a cool climate chameleon keeper and not owning a meter (yet) this Cfl info. is quite valuable. Thanks for sharing your readings all.
 
Do they make any tube fixtures that are no wider than 18"?

If so I would get one and put an arcadia bulb in it.

Imagine it with screening? :eek:

Depending on the kind of screening, (ie. mesh size, coated, fiberglass, etc) ... it will knock that reading down anywhere from 20 - 40%. :confused:

Say hello to MBD in a few months. :(

Cheers!

What is your opinion on the ideal reading of UVB for panther chams at there basking spot?

In the shade outside you will still even get a reading of @200 from a solar meter. I guess that would depend on the season and time of day as well but yes it is all opinion and personal preference on what works as far as how much UVB you expose your Cham too.
 
just a question, but what basis are you all using for your UVB exposure?

the amount present in sunlight @ earth level in madagascar? a scientific study? or ...?

Hi All.

I took these readings yesterday.

Brand new bulbs ran approx. 1/2 hour to warm up and then took readings.

I just pulled random ones out of my inventory of bulbs to test. Because of time, only one bulb of each kind was tested. So someone may wish to conduct these test with more than one sample of each.

Readings were taken 10" inches away.

Bulbs are in an standard Exo Tera 12" reflector with no enhancements. (ie. no reflective tape or tin-foil added.)

*e-hem* ... Exo Teary performed pretty much as I have grown to expect from that brand as far as lighting is concerned. :(
Can't imagine what it's readings would be like in 4 or 5 mo. AFTER it's out-put decays.(!?) I know folks love them because of their price.
Now you know... that's all I'll say.

It will be cool to compare the Arcadia CFLs when they are ready in 110v for the US market. :cool:

Hope this helps!

Sincerely,
Todd

PS. See why Solarmeters are the path to true enlightenment? :D;)

The 6.2 (green one) is the reading most people refer to when talkig about UV levels. Micro Watts per square centimeter.

Would you mind showing the exo 10.0 Bulb in your comparison as well?

Thx.

Others experience, my experience. I am not aware of any actual scientific study, or the actual exposure in Maddi... If you or anyone else have any info on this topic, PLEASE share! :)

Im a turt keeper and we in our hobby are asking the same things.

The thread above may be of interest to some of you as it discusses the differences between the two meters. If you all know this I apologies.

Please bear in mind that each Fluoro lamp will have different phosphur mixes. This means that there are different wavelength peaks all along its spectrum. The 6.2 reads a broader part of the light spectrum than the 6.5.

So two different lamps may have the same UVb content but if one has a different UVa content, say its higher, then the 6.2 will give a higher for that lamp even though UVb is the same. Dont get me wrong UVa is also important.
Each lamp must have a calibration factor for the meter a direct comparison of lamps without calibration could be misleading.

The 6.5 has a sensitivity that follows the Vit D3 curve so is a better meter if UVb is all that you are interested in. In the vid Frances uses a 6.5.

The reference to John is because he is the product manager for the reptile section of Arcadia.
