Hi, Flavia. As Steve says, these lamps will certainly be emitting UVA but without using a UVB meter on these tubes, you can't really say whether they are...

Hi Melody All the electrical bits in the magnetic ballast unit can be discarded - this includes the inductive ballast, the capacitor, and the starter unit. The...
Personally I prefer the old brick style ballasts. They work with more bulbs, and the heat they put out is welcome in an iguana enclosure. ==== Robert Allen ...

Hello Henry, The "old" magnetic ballasts for TL-lightning flicker on a rate of 50 Herz (Europe) due to the frequency of of the power supply. The modern...
Very interesting. We can't "see" any 60 HZ flickering from US lamps... but I do recall sensing some from a 50 HZ hotel bedside lamp last time I was in the UK....
Hi, guys. I just had fun looking into this. Here is an interesting paper trying to review the evidence for the effects of longterm use of fluorescent lighting...
If no one has pointed this out .... The flickering frequency of a "normal" fluorescent lamp driven by "normal" 50 Hz mains should be 100 Hz (or 120 Hz for 60...
Interesting question Henry. But I have brought back so many near death iguanas with R40 SPOT MV bulbs (that really dance)in the past to great health and...
When people send in their solar recordings, occasionally we have had ones that seem almost "too high to be true". For example, last year the one of the highest...
It is an interesting study. I have a similar experience not long ago when I was comparing my UVB meter with readings obtained from the local weather authority....
Good article. Yes - I've noticed higher readings when the sky looks like those pictures in the paper. Especially when the sky color is deep blue in-between...
I could not see the graphs on the files. Is there something wrong or is it me. 75% in three months is what most MV bulbs decay. The decay after that is ...
Wow, some fascinating stuff there! As Olihouhk says,the flicker frequency of a normal magnetic ballasted fluorescent will be 100Hz (UK) or 120Hz (USA) since...
I cannot seem to find the exact answer to the following question. Many of the posts are above my head. I use Reptilsun 5.0 bulbs for both animals. What is the...
Hi, Bill. The UVB meter that most of us use, which has proven very reliable and easy to use - and comparatively, extremely inexpensive when you consider that...
I need to change UVB for my female iguanas cage, she was using the Megaray and I am changing to a flouresent and want to know if I add 2 48" Reptisun 10.0 with...
Hi, Donna. I'm not the best person to answer this because I've never kept an iguana and neither have I tested any 4ft tubes... but I guess it's gone all quiet...
Hi, We just set up one of our iguana's (Kermit's) new cage with 2 four foot reptisun 10 bulbs. We use the fixtures that you have to wire yourself. They have a...
Thanks, Sean! Fascinating.... ... Were those the readings you got from the two tubes together, ie. the reading is from both tubes at once? Or is that the...
