UV light meters and UV light sources?

Note: I initially posted this in the exposure group, and somebody suggested that I post it here.



I’m looking to start alternative processes, beginning with cyanotypes, and perhaps going beyond that.

My plan is to use a halogen work light as a UV source.

From what I understand, the output of these varies over the life of the lamp, and even to some extent of the duration of a printing session, which seems to call for a UV light meter.

Does anyone have a suggestion for a reliable light meter that is not too expensive? (a relative term, I know.)

Is it possible to save any significant money by trying to make a DIY version wthout sacrifgicing reliability?

And does anyone have any thoughtds as to whether here would be a better choice for a light source?

I use a face tanner for years

Would be interested to hear what you think when you get it running. Did you get the 1000w or 750w?

I got the 1000w. Mine hangs with little ratchet pulleys so I can vary the height from the table. I've since used it to make cyanotypes and it works fine for them.

I know this is an older post but.....I picked up a couple 1000W MH parking lot lights (Hubble) for 50$ a piece. Take about 5 min. to warm up but BLAST the light. Im gonna make a cabinet to set the bulbs and ballasts in when I get time. For now I prop 1 up about 20" away from my negative/positive and let it burn. Gum prints in about 90-200 sec. and that is with 1 lamp. The lamps run at about 3800K. Im all about the money
