This is my first time reading sci.electronics: I hope these questions have
not been asked before.

I am building a light meter. Can anyone recommend a visible light  
phototransistor for this purpose.  I have only come across phototransistors
that work in the IR range.  I noticed my camera uses a "Silicon Blue Cell". 
Is this a phototransistor or ...?

Are blue diodes available? If so, who makes them. Any suggestions for Canadian
distributors?

Any help would be most appretiatied,
