    Lightbulb Strobes: CDI vs CLS

    I did three minor tests tonight using my news camera in the garage.

    The results are not bad but the xenon strobes played havoc on my iris. I think it would be much better outside in an open area where the light can disperse evenly.

    Test 1: comparison of CDI's xenon all flashing at the same time like the LED's.
    Test 2: comparison of CDI's xenon vs LED. Xenon on the left, LED on the right.
    Test 3: comparison of CLS vs CDI xenon's. CLS on the left and CDI on the right.

    Thanks for the video William. The xenon tubes are likely the same size between the CLS and CDI strobes. The designers can only put a certain size tube into the enclosure. So, I would imagine the light outputs would be the same and flash rate looks the same.

    Another important test will be to see if condensation accumulates. John was going to put one in the freezer and make it blink--preferably overnight. If the CDi strobe passes the condensation test, I plan to take my CLS strobes and drop them in that oil spill in LA. The CLS strobes will absorb the oil like it does condensation and make the spill end.

    John the nation awaits your condensation test.

    Obviously the CDIs don't blink at the same time. But the other test are hard to tell. What is your "live" impression of these lights ? Is LED worth it or should we all go for the Zenon .. ?

    Denny I'm not sure that is the case. The camera's auto exposure circuitry seems to have trouble with the sudden flashing. William do they flash at the same rate? William's auto exposure circuitry is much better suited for the test.

    To me and my tired old eyes looking at the video:

    Test one, CDI xenon, started blinking at the same time, then random. Probably a small precharge would keep them random, just as I did with the CDI LEDs last year.

    Test two, CDI xenon vs CDI LED, to me it looked like the LED has a faster flash rate

    Test three, CLS xenon vs CDI xenon, seemed to be very similar.

    I'll probably have a mix of all three on the same string, since I have all three in inventory and need to go ahead and use the remaining CLS units until they go ahead and die, getting them out of my way.

    EDIT: Thanks William for doing this test and video

    Freezer ? I was going to use the refrigerator. I'm thinking the freezer air would be too dry and cold at 0 degrees F. Not at all like my typical display weather.

    I might get to it this weekend, Been working 8 till 7 M-F and 8 till 5 on Saturdays the past couple of weeks and haven't felt like doing much of anything except trying to get my Memorial Day display up and stirring up trouble with useless posts here!

    Quit whining and buck up John. Yes, the refrigerator would be better. Don't get all I told you so with me. We need to make sure that the strobes are in a moist environment. Maybe put them in a plastic bag with a small container of water. The water will insure the humidity is high enough. Geez, I used to go grab a humidity chamber and run tests of this nature when I worked for The Man. Now I'm a free man and I have to rely on John's refrigerator for scientific tests. That almost sounded like whining but it wasn't. I know whining and the last post was clearly whining.

    After looking at the video again, the CDI xenon strobe seems to be housed in the same enclosure as the LED strobe. If so, I would bet Walter's Land Rover that the xenon will not have any problem with condensation. But what do I know, I rely on John's refrigerator for tests. I'm losing my mind.
