It is UVB that I have.
I didn't think you were trying to argue. You couldn't have if you wanted to being you had not watched the video you added. I just took that and watched part of another to get an idea of what you were suggesting.
As to the usage of the word "deserves" it certainly shows your feeling on the matter. Certainly stands out and seems very pointed. I would say you are in no position to assume what anybody else's snakes deserve. You say it can't hurt. Really?
I have how many snakes compared to you? 14 - 2, I believe. Have you priced a Zoo Med T5 bulb? A two pack on Amazon is $50 at the moment. So let's say I had one for every snake. I would need seven packs which is $350 before tax. You don't think that could hurt some folks? Could I pay it? Sure. But why? If my collection is not going to really prosper with it the value is simply not there in my opinion.
I am certainly all for doing what is needed for my snakes and don't mind spending money.....but I am not into wasting it. I have the UV light I have because my Ball's tank does not get enough sun to provide what the live plants need that are within. That is it.
Now if you or anybody else wants to put UV lights in their snakes cages I am all for it. I just would refrain from suggesting it to others as if not doing so is some how negligent.
