4:1 Photoresistor Options

[Aleph Null]

The BOM calls for a VTL5C3, but I have Tayda photoresistors on hand. Light resistance is 5k which seems to be about right. If I use them with a 5mm red LED in this circuit, will I regret it?

I'd love to hear from anyone who has done this. Did you have to change any resistor values to get good results?
