Griffin builds a powerful, DIY video light for $86, using hardware store parts, and eight 100-watt-equivalent compact fluorescent (CFL) bulbs. Also discussed: three-point lighting and color temperature / white balance.
Light output: 12,800 lumens, or 13 incandescent bulbs worth of power, but uses only 184 actual watts
Color temperature: 5,000 degrees Kelvin (often called "daylight")
Power consumption: draws 3.2 amps
