    Yeah, I know. They are a pain in the butt. But they pay the bills to keep my server running. Just a fact of life, I am afraid.

    Want to get rid of them? Simple. Just become a Contributor level member or above and they will be gone. -> Please click HERE."

    Is that too much for me to ask of you to keep this site running? Well, sorry about that. I too wish I could get everything for free. But alas.....

    Google Adsense ad revenue for December, 2025 was just $30 over the cost of the lease for the server running this site. So, in effect, the money providing the incentive for me to continue running this site is coming SOLELY from the paid memberships and sponsorships here. Which honestly ain't much....

I'm sure that this has been brought up before on here but I wasn't able to find anything. I've had the 5.0 Reptisun UV lighting on my cresteds since I've had them but I've debated with myself whether they really need it or not. Would it be just as sufficient to feed them calcium with vitamin D3 and forget about the UVB? UV lighting can be so very expensive and if they don't really need it than I'm wasting my money but if they do need it than I will definitely keep spending the money. Does anybody have any concrete evidence on whether Cresteds need it or not?
 
If you have living plants in there then UV is a good idea, as for the gecko they do not need any special lighting. I would go with a 2.0 just for the plants... or maybe a chlormax....
 
Plants do not necessary require UV lighting -- rather they need high quality light with high intensity.
 
Actually, no, UVA and UVB have nothing to do with measure of intensity of light.

UVA and UVB are from the invisible spectrum of light, not measured at all as intensity, rather in wavelengths. The classification of 2.0, 5.0 is equivalent to the percentage of total energy output of UVB bulb.

Light intensity is in reference to light brightness. Intensity is measured in the lighting industry in lumens, luminance or lux, or very specifically "intensity of light per unit area of its source."
 
Thanks. Don't need the link. I am not an amature when it comes to lighting, I just try to make it simple for everyone else to understand. Wrote a book that included one of the most comprehensive sections on lighting for reptiles.

What I have found is that many people in the reptile industry think they know something about light but have only learned about lights from other reptile people. A lot of lighting information distributed by the reptile industry is not correct or misintrepreted.

A lot of people just go on the internet and do searches and believe what ever they read without considering the sources.
