The start current is different for xenon lamp and halogen lamp to decide .

1、55w halogen lamp ：For a cold start, the current as 30A(could create a controlled amount of surge current. various interface no time to generate heat. so The system with cooling device can prevent the lamp from damage.
)
2、55w halogen lamp ：For warm start:the current as 10A(The duration of execution is short).

3、55w halogen lamp ：normal operation current was 4.5A-5A .

4、35w xenon lamp ：For a cold start, the current as 7A( The designer was specifically to adopt low currnet, ) the duration of execute for one second , then the current was descending in 1~5 seconds.

5、35w xenon lamp ：For warm start:the current as 5A，7A，10A.

6、35w xenon lamp ：normal operation current was 3.3A .

Testing equipment and measuring instrument of LED source
With the development of science and technology, the led source is changing rapidly.the led source aroused great attention because of its incomparable advantages compared with traditional light device. has a higher luminance, cheaper and lower-powered devices,long service time.
Since the above-mentioned characteristics of led source. Different with the traditional method of the measuring.in here we have testing equipment for led source. let’s look at how test that led source.
