An electric lamp, particularly a halogen cycle lamp, adapted to be used as a dual filament automotive lamp which has an opaque end cap coated on the hard glass bulb. The end cap coating comprises a mixture of carbonyl iron powder and silicon powder, preferably in a ratio of between 1.5:1 and 4:1 (by weight) and more preferably in a ratio of about 2:1. The lamps have the important advantages of excellent utility during service coupled with the ability to be manufactured at relatively low burning in temperatures, i.e. in the order of about 530 DEG C. |
