The Uvb bulb I have is a 75 W Night-Glo,Neodymium Moonlight Lamp * By Exo-Terra*
Exo Terra - Make Your Reptiles Feel At Home. Which says its designed for Desert and tropical terrariums, Simulates Natural Moonlight, Perfect for nocturnal viewing, and can be combined with repti Glo / Sun-Glo for a 24 hour cycle. However as far as the Night glo bulb you are right on the needed uvb rays you just woke me up man thank you!! The Night glo bulb by Exo-terra does NOT give off uvb/or uva rays. But does provide visual and infered rays so therefor is still providing a heat source and simulating moonlight. The repti-glo bulbs do give off all of the needed rays. The Sun-Glo does give off uva and does not give off uvb. The reptiglo once again does give off all of the needed rays wether uva/uvb/visual and infered. Repti-glo uvb also gives off uva. the reptiglo uva also gives off uvb, uva, visual and infered. So the SUN Glo are infact like you said a false advertisement. THANK U
