Seriously, I don't understand. With all the money and time investment in getting everything one needs to have a darkroom, what is the deal with saving $20 and possibly fogging prints?
I have had the same thoughts. I have plenty of 'proper' incandescent safelights with Kodak filters in my darkroom, and they were very inexpensive. However, I saw this ad for a Kodak "Bullet" style safelight in the UK for almost 200 pounds. So, maybe not everyone lives in a location where high quality darkroom equipment is essentially free for the taking.
