A safelight is basically just a dim bulb with a colored filter, right? So, is it really necessary to buy a specialized safelight, or is there a way to make a makeshift one of your own?

I was working with premium equipment, by-the-way - Thomas Duplex and a Saunders VCCE LPL 4x5 enlarger that was brand new! <<more snips>> Then I tested with the Kodak test and found I was getting image fogging with only 1 minute of exposure to my Thomas Duplex Safelight - the one that boasts you can read a newspaper with it. (I was never sure why I would want to read a newspaper in my darkroom, but their marketing department thought it would be cool, I guess.) <<even more snips>>
Lee L said:Yes, the bulbs themselves are colored red, at least the Adorama 11W and the 7.5W cherry lamp it replaces. The cherry lamp has what looks like a red enamel coating, and I just visually compared the 7.5W to a red LED lamp, and the color looks about the same. But that's not the way to judge accurately. Both fit a standard Edison lamp socket.

You really use red???
blaughn said:[...]The symptom - I found that as I moved from 8x10 prints up to 11x14 or larger (or increased size to crop an image,) I had to increase contrast to get bact to the original desired impact. I thought this was normal. It isn't. It is a symptom that you may be fighting an UN-safelight and/or enlarger light leaks. In seminars I have attended, this is the number 1 most common problem.
If you haven't tested for enlarger and safelight problems, I urge you to do so. Go to the Kodak web site and search for 'How Safe is Your Safelight?.' From the items returned by this search, click on the one titled 'K-4'. This will open a PDF file that will guide you through the process. It is a bit complicated and boring as all-get-out but it will smoke-out your unseen enemy like no other test. Post your responses after you do this. I am curious as to how many of you discover a problem.
