Let's turn on the lamp and see what the startup current looks like. Holy cow! 4.4A! That means that it's using 121.6V x 4.4A = 535W! Let\'s figure out the power factor at startup. Power Factor = W / VA = 150 / (121.6 x 4.4) = 0.28! That means that only 28% of the power is being used by the lamp. Let's not forget that it's normal for HID lamps to draw more juice at startup. Therefore, the lamp is probably drawing more than 150W and is skewing our power factor calculation. So let's let it run for a while....

A chelate is a chemical compound composed of a metal ion and a chelating agent. A chelating agent is a substance whose molecules can form several bonds to a single metal ion. In other words, a chelating agent is a multidentate ligand. An example of a simple chelating agent is ethylenediamine.ethylenediamine. A single molecule of ethylenediamine can form two bonds to a transition-metal ion such as nickel(II), Ni 2+ .DTA is a versatile chelating agent. It can form four or six bonds with a metal ion, and it forms chelates with both transition-metal ions and main-group ions. EDTA is frequently used in soaps and detergents, because it forms a complexes with calcium and magnesium ions.
