To optimize the total lifetime of the Philips MSR lamp Gold 1510 SA/DE Double Ended lamps, the caps are plated with gold. This provides superior heat protection and thereby minimizes premature failure of the lamp and lamp holder, as well as ensuring extended consistent performance. In addition, the highly innovative P3 technology, developed by Philips, allows the MSR lamp Gold 1510 SA/DE light bulb to be used at higher temperatures, which further extends service life and consistency of high-quality light output.
