    The Nightsword project

    Okay I'll bite.. As you read through the thread, you'll see that improvements to the design were continual through the entire period. Sure I could have finished this project with the initial plans within the first year, but compared to the evolved plan... 1) The performance would not...

    The igniter and power supply design are actually not at all complex to me at this point. Yes there's many variables but they are second nature now. I have the schematic sorted out and I've wired up the components to run tests and determine suitable component sizes for the boost phase transition...

    Sorry for the delay, I didn't want to put this thread at the top of the queue without any new info. I've had no time this past year but I've recently made some headway. The prospect of designing the boost and ignition stages of the power supply had been a bit daunting for me because electronic...

    New Short Arc Heavy Iron in My Inventory - AEG XSW30U (E) German Leopard 1 Tank Light

    Very cool find! I look forward to studying it once I get back from vacation. The manual could be translated to English. There's online OCR (optical character recognition) tools that generate text from PDF scans. That text could then be translated with Google translate. But at least the drawings...

    Peak intensity falls within 1 degree, corona with 2 degrees. I'm sorry but personal issues are putting this off for a bit. LED1982 it would be a pleasure to have you visit when it gets to that stage.

    The Osram rep does not recommend DHP lamps based on experience. They're for non-moving digital projectors, while XSTAGE is more stable and less expensive. So really there's no choice but to stay with the XSTAGE 2000W. So next I'll be working on the design of the portable power supply for this lamp.

    Seems the lamp isn't well stocked. I'll first have to contact Osram to ensure it won't be phased out.

    Okay I see where the confusion is.. You're going by 70,000 lumen for the 1600 W, which is correct for classic 1600W Xenons. How I'm measuring lumen output is by taking lux measurements at each axial angle and calculating the total lumen output. This method has produced lumen results consistent...

    BVH, what's also nice about the LFL beam is the lack of corona light that tends to wash out your view of what the spot is illuminating. To be clear, nothing is changing regarding the design with long focal length and retro-reflector, so the beam patterns will still be the same uniform beam with...

    Here's what the XSTAGE 2000W is measuring at Min, Nominal, and Max power... 21.35V @ 70A= 1494.5W -> 76,660 Lumen 23.45V @ 90A = 2110.5W -> 118,203 Lumen 24.95V @ 110A = 2744.5W -> 150,009 Lumen I thought the lumen output on the spec sheet was under rated, but this is more than I expected. I...

    Need Spotlight to Turn Off Mercury Vapor Yard Light

    I'm thinking maybe borrow a drone. Good luck!

    Lamp life is the same. Below rated minimum current, insufficient electron flow causes the Anode to "deactivate", also tending to result in arc instability. Within the rated current range, the Anode remains activated and lamp life is the same.

    Operating Xenons under their rated range will very quickly destroy the electrodes. I gather because when under-driven, electron flow is not enough to carry heat away.

    Yes, by thumb control. Also, if we design the max power to be the nominal 2000W for the XSTAGE, it would be significant performance over the 1600W lamp while weighing 11.75 lbs. Weight would be saved when designing for max 2000W rather than 2500W because the cooling capacity would be less and...

    Hi all.. We can generally pick from two of the three: high efficiency, high luminous intensity or fast startup... Fast Startup + High Efficiency = Metal Halide High Efficiency + Luminous Intensity = Pure Mercury Luminous Intensity + Fast Startup = Pure Xenon These Xenon's when operated at...
