Factors Affecting The Lifespan of HD Projection Lights

When replacing of the bulb of HD projection lamps, it is likely to produce abnormal high temperature during operation. When observing glass bulbs, we will often see some burning spots. Its brightness will also thus decline, and the situation of loss of transparency may occur. This may even happen to the quartz glass under ultra-high temperature for a long time as its surroundings is often more fragile and thinner, which easily lead to bursting. Therefore, it is recommended not to use high-definition projection lights for more than 4 hours.
