I am building an incubator and I found 4 never used light bulbs but I don't if they will work. Here's what the box says: "A19. 120V. 1000 hrs." ; "71 watts" ; "Lumens:1050" ; "RoHScCompliant". Ok so I know nothing about what type of lightbulb to use in an incubator. Will these work? If they don't then what kind do I need to buy? Also Is a thermostat absolutely neccessary and if it is where do I get one?
