Hi Henry, ... What do you want to vizalize? The flicker frequency is known in all lamps, it is always the double of the operation frequency. If the operation...
the thing is: an authority vet asked me: chicken farmers pretend to use electronic ballasts with their fluorescent lamps but have electromagnetic ballasts. so...
Hi Henry, you see the flourescent tube pictures on my homepage: This is conventional ballast. When using an electronic ballast you would not see any light...
I wish it was good heat and powerful UVB here. It's just rain, rain, wind, cold, little bit of sun, rain again... I don't know about iguanas, I could do with...
What do you think about induction lamps as a light source? They have no flicker, CRI>80 and with 40W they have luminous flux 2400-2800lm (80W has 5800-7000)....

Has anyone done any experiments on the possibility that lizards might have their sleep habits detrimentally altered by the low light (red) produced by coil...
Coil heaters produce (visible to us) a low level of red light; and so I assume that it is visible to the lizards. On the other hand, as I think about it, the...
