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.
Fluorescent light fixtures are commonplace in both residential and commercial settings. Fluorescent light bulbs have a typical lifespan of 8,000 to 15,000 hours, and ballasts often work for more than 50,000 hours. Fixtures made since at least the year 2000 generally do not have a starter, just a ballast.
