Final answer:
Hot lights are bright and give a warm color. LEDs are easy to use and more powerful. Flashlights generate less energy. Cool lights are similar to daylight and can be used with a flash device.
Step-by-step explanation:
A: Hot lights - They are very bright and give a warm color. You can change the color balance, but it does not mix with daylight or flash photography.
B: Light Emitting Diode (LED) - They are easier to use, offer more power, and have fewer limitations than hot or cool lights.
C: Flashlights - They generate only a tenth of the energy produced by light bulbs.
D: Cool lights - They are fluorescent and are similar to daylight, so you can use them with a flash device.
