Sorry I was not clear enough. There are 2 types of blacklight commonly available, one is:
The party light your referring to. These are sold with the term "BLB" fluorescent blacklight lamp. The tubing (or glass of the bulb) is made from a very deep violet-blue glass known as "Wood's glass"....and are commonly used in night clubs etc.. for special effects due to their ability to make fluorescent objects glow very brightly. This is not the bulb to use. The second is: The "BL" fluorescent blacklight lamp, the glass (of the bulb) is not dyed to block visible light, the glass is the normal "cool white" fluorescent lamp glass colour. This is the blacklight bulb I'm referring to. I have seen many species of nocturnal geckos partially exposed to the sun, during the day in the wild (ie: at the edge of a crack in exposed rock etc). ----- Original Message ----- From: "Mario Stinso" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, 6 February 2002 7:49 Subject: Re: [Gecko] UVB lighting > What I was refering to was that you mentioned: > "We have been using the NEC and Sylvania BL blacklights since > the 80's on the entire herp (amphibians, snakes, geckos etc..) collection > (around 1000 animals) and have never had any eye or skin cancer type > problems attributed to the bulbs" > This is the black light I was asking about, and now you said you replied > saying that you were talking about a normal "cool white" fluorescent.
