Can I measure the brightness of a glow stick with this? Need it for a science fair project.

Yes, but you'll get different results for different colors. For instance, green glow sticks which look bright to you will not look as bright to the meter, but red glow sticks will look brighter to the meter. You can avoid problems by making comparisons only of the same color. What form will your project take? Glowsticks are not my invention, but they were invented right across the hall from me in the lab where I used to work in Connecticut. Can I be of any assistance to you?

When used in photography, does it give you the correct settings for f-stop, shutter speed, ISO ?

Unfortunately not directly on the meter. You would have to use a lux conversion chart for that purpose. In my case it is being used to calibrate medical equipment light output.

I would like to use this product in outdoor low light levels for bat research. Will it read in after sunset but not totally dark light levels?

It might, however this is really for measuring the intensity of light. You're going to have low lux levels at dusk and this device might not read anything that way.
