A lighting device includes a parabolic reflector, a light source and a lens. The layout verification is performed for both device packing density and interconnect packing density and the efficiency is calculated based on the total available area and reported. The slave server layer can request a delta from the master server if the slave data is not current. Methods of making such dispersions are also described. The tape is formed by casting the silicone gel on a suitable backing and that backing is removed from the tape at the time the tape is used to wrap around the electrical connection. In the methods, the fraction of hydrophilic residues in the polypeptide is controlled so as to maintain the solubility of the polypeptide constructs.
