Ancient Egyptian makeup For makeup too, the Egyptians had to turn to the natural ingredients that were available at the time. They used henna to colour their hair and to tint their nails, saffron was used as an eyeshadow, burnt almonds were used to darken their eyebrows and they used red ochre for their lips.
A lighting ballast is a piece of equipment required to control the starting and operating voltages of electrical gas discharge lights. Examples of gas discharge light sources include fluorescent and neon lights and high-intensity discharge (HID) lamps.
For a lighting ballast, the ANSI ballast factor is used in North America to compare the light output (in lumens) of a lamp operated on a ballast compared to the lamp operating on an ANSI reference ballast. Reference ballast operates the lamp at its ANSI specified nominal power rating.
