①The energy distribution of the radiation spectrum is close to that of sunlight
②The spectral distribution of the continuous spectrum part is almost independent of the change of the lamp input power, and the spectral energy distribution is almost unchanged during the lifetime.
③The light and electrical parameters of the lamp have good consistency, and the working state is less affected by changes in external conditions.
④ Once the lamp is ignited, stable light output can be achieved almost instantaneously; after the lamp is extinguished, it can be reignited instantaneously.
⑤The light efficiency of the lamp is higher, and the potential gradient is smaller.
⑥Suitable for movie screenings, searchlights, locomotives and simulated sunlight
