Hi there,
I wonder if anyone has experience with using blacklight and UV fluorescence set-ups.
From what I can find, it isn't recommended that these be used near organic material and may require ventilation. It kind of excludes the darkroom for use.
Has any one here got a black light set up? Is it possible to do indoors, or does it need some kind of contained or ventilated space. I wonder if anyone can recommend an ideal frequency for the light source (being in the UK, we use 240V 50-60 Hz).
Would be grateful if anyone could give any suggestions.
Kind regards. |

I suggest you do your research again. I have used these standard photographic 'tools' for years in forensic photography. Even the basic Wikipedia entry gives one enough information to realise that with common sense, these setups can be used in any indoor room. 1000s of spare bedrooms here in the UK contain tanning beds, which use the same light source.
I do have a very old UV lamp (pre 1950 but still very useful) which kicks out plenty of ozone - due to the high voltage power source required for the lamp used. However normal darkroom ventilation proves quite adequate, but I doubt that you would find a similar lamp outside of a museum, so you be OK using modern UV light sources. |

Many thanks for your thoughts Glenn.
It's not easy finding any references to practical installation of indoor black light sources on the net, bearing in mind that many modern darkrooms, including mine, use centrifugal filtration rather than positive-negative pressure ventilation. The accumulation of ozone in such an environment and UV light of particular wavelengths, being associated with a global incidence of skin cancer, particularly melanoma.
Can recommend a modern UV light source?
Many thanks. |
