I know there is no such thing as a 'silly question' but as i tended my Day Gecko Vivariums today and i thought - "How well does the 'beneficial' part of the light, produced by an ultraviolet bulb, pass through glass or plastic?"

I know that you can't get burnt by the suns raise when sitting in the car with your windows up, as the windows actually block the suns harmful rays, i assume this would be the case with light bulbs and glass or plastic vivariums!! ( just for the record, my light bulbs are on top of Exo Terra tanks and only penetrate through mesh )

Anyone got any ideas or technical information?

strictly speaking even mesh can block UV rays. if the gaps in the mesh match the amplitude, or wavelength of the rays then they can be nulified.

oooooo that was a bit sciency, gona go and drink a beer to bring my IQ back down!
