Kodak Safelight Bulb and Filter Question
I'm almost into my darkroom....question is ... I've got two 20-30 year old
Kodak Safelights, the grey metal ones which take the ~5" glass filters. One has a red bulb in it the other no bulb. Do I have to use a red bulb? Isn't that what the glass filter is for? [Filters a OC, two #13s, #10 and #3 what do I use for black & white?] If I can use any bulb what is the maximum wattage? Thx. |

You should use a 15 watt bulb or smaller in your safelight. For the #13 filter (for Panalure and some colour papers) Kodak recommends a 7 1/2 watt bulb. You should test your safelight. Kodak has lots of good information at: www.kodak.com/global/en/consumer/products/techInfo/k4/k4Contents.shtml The 0C filter is for black and white enlarging paper. Some fixed grade papers can be used with the brighter 0A filter but multigrade/variable contrast papers need the 0C filter. The #13 and #10 filters can be used with Panalure and some colour print materials. These are rather dim safelights, and many people just figure out a way to work in complete darkness. The #3 filter is for developing panchromatic films by inspection. The safelight is only used when the film is at least half developed and then only for a very short time. It could be handy in emergencies, but it isn't something you would likely use often. Peter. -- |
