Royal Industries for the blind made a one piece light probe that used an N
cell battery which I liked very much.  But I don't know if it is still made,
or if there is a US distributor for it.  Sorry I can't be of more help.

Subject: OT: light sensor

Hi all,
i picked up some part-time hours at a local radio station and I need a light

sensor to tell me the status of various things on the audio board. 
Somewhere, I have 1 or 2 of the triangular-shaped ones with the slide switch

and the built-in permanent shade around the sensor. That's what I used when 
I was working before and it worked just great for that purpose. However, I 
can't find it and I need to replace it sooner rather than later. I also have

a sensor from the NFB which is essentially a frame with 2 tripple-a 
batteries and it works well but is far too sensitive for this job. It has a 
removable shade but I cant get it to stay on. Any reccomendations? Thanks 
and 73. Lou WA3MIX
