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.
What are Ballasts? If you have been doing any sort of research on purchasing an HID conversion you will inevitably come across the term ballast. What ballasts do in a conversion kit is relatively simple. The wiring harness that your car uses to power the stock halogen bulbs usually run at 55w. When you upgrade to an HID conversion, the bulbs that are used only require 35w (as a general rule of course).
