For blonde hair, or to add subtle highlights, mix 1/2 cup of strong chamomile tea, Â¼ cup fresh lemon juice, and Â¼ cup coconut oil in a blender until emulsified. Apply to hair and roots and cover with a shower cap. Sit in the sun, or use a hair dryer to keep the cap warm for 45 minutes to 75 minutes.
Ballasts limit the current through an electrical load. These are most often used when a load (such as an arc discharge) has its terminal voltage decline when current through the load increases.
The ballast in such systems can equally be a resistor. A number of fluorescent lamp fittings used a filament lamp as the ballast in the late 1950s through to the 1960s. Special lamps were manufactured that were rated at 170 volts and 120&nbps;watts. The lamp had a thermal starter built into the 4 pin base.
