Hey since I am in south Africa they don't sell bulbs measured in kelvin here only in watts which doesn't really help so I spoke to my physics teacher about it an he told me you can measure the temperature of the globe and times it by 273 so what I did was take my tank thermometer and stuck it to the lid near my light an got a temperature in degrees celsius and did the calculation I'm not sure about the calculation for (f) but hope this helps
