I haven't used the Adox Super Safe light. I use a good old Ruby glass bulb, as well as two 10x12 Kodak safelights with 7 watt bulb in one and a 15 watt bulb in the other. Never a problem wit any ortho film.

Just wanted to say hello, and say THANK YOU for the wealth of info here...a real treasure trove.

Getting started with LF, and will post some images soon: green sensitive x ray film with caffenol...

thanks for having me!

Welcome!

I need to try caffenol, only yesterday I found The Caffenol Cookbook

https://www.caffenol-cookbook.com/Th...0Tutorials.pdf

and as you know X-Ray IS REAL FILM

[AdrienneCatanese]

Thanks Tin Can

and yes, not only is it REAL film, it is REAL CHEAP film compared to my precious Ilford HP5 (what i usually shoot in 35 mm)...
my feeling is: XRAY makes me able to afford shooting LF ALOT, which means more learning, which means more mastery...I tend to like the longer, more challenging, path in most areas of life... i have the patience for stuff like that!

wish me luck--will share as soon as i have some images!

Good luck. I've had a fair sharw of safelight fogging qith xray film myself. Most red leds are not safe enough due to a secondary emission peak in the green part of the spectrum. A dim red led with an additional red filter fashioned out of a sheet of rubylith film works very well in my experience.

Okay, I have a question about UNSAFE safe lights: since a lot of the red safelight filters are expensive, could I ever just put like a red glass VASE over my existing red LED "safelight" bulb...I'm a big thrifter, so I"m wondering if a $2.99 RED GLASS vase (see these all the time) placed over a less-than-safe "safelight" LED bulb would work as well as Ebaying a more costly filter...thoughts?

Adrienne, spend your $3 here:

These are perfectly safe for reasonable use at a normal distance. I tested these once by putting paper directly onto the light for 1 minute and it was only fogged slightly when developed - this is obviously unreasonably large exposure at very close range, so they are perfectly safe for normal use. I have found these to be 100% safe for developing x-ray film hanging about 4-5 feet over the trays.

I use these, in a cheap reflector and bounce off ceiling or wall, usually 3 in roomy DR

I bought 6 years ago when they were 1 watt and safer, but the 'improved' 2 watt also works
