Yes they are. Just be careful to make sure it complies with the FAQ here: https://www.soinc.org/mission-possible-1

For this task, I'm just using a G4 Halogen bulb, a photoresistor, a TIP120 transistor, and an Arduino. It has been working reliably since December and has run consistently hundreds of times. I highly recommend this method, because it's easy to do and it is very unlikely to fail.

If the only requirements of this task involve an exothermic action and light, could one use an incandescent flashlight to shine on a photocell in order to activate the next action? Since incandescent bulbs actually produce heat as opposed to a LED.

Yes you can. I think thats how everyone else is doing it

Could you explain how you did this? I'm very new to arduinos but I feel like it's the best and most reliable way of doing this task

Very simple code, you can find examples of how to use a photocell and an LED on Arduino online. A low-voltage light bulb will work in an identical way.
