    Scored a Nice 16" Parabolic Reflector. HID or Short Arc? Test Beamshots w/ HID.

    Re: New Beamshots w/ HBO200 Lamp Just a quick update to follow up on if this can be run on a 12V inverter. So far, no. I've tried up to a 750W continuous, 1500W peak inverter, but it cuts out as soon as the SA power supply is turned on. It cycles on/off but won't let the PS wake up. I...

    MBI #3 - Codename: HF

    I'm extremely.......satisfied, yes, that's it....to find this light. It's just about a perfect match for my desires for a keychain light. What does that desire entail? Well, I often wear my keys on a belt loop, and I like to keep them compact. I work in a world of engineers and product...

    Re: New Beamshots w/ HBO200 Lamp Tonight it is foggy. "Hmm......I bet the searchlight will look cool", thinks myself. Yep, it does. Fun session. As you can see, humidity makes a huge difference. The beam doesn't go NEARLY as far as it would on a clear night, but boy-oh-boy, can...

    Re: New Beamshots w/ HBO200 Lamp In the cold air, with the fire burning and bright exterior house lights on behind that, it was pretty faint from 100 paces away. The HID was just as visible from a twice that far, but in a very dark area with higher humidity. So, it varies, a lot. I'll...

    Re: New Beamshots w/ HBO200 Lamp Finally, here are 3 shots with bracketed exposure, to show how it affects the look of the beam. First one is normal, then +2 and +3 stops overexposed: There, I bet that's plenty. I wish I had further targets. After I test out the 12V inverter, if that...

    Re: New Beamshots w/ HBO200 Lamp Here is another batch of beamshots from tonight. It's about 30F, cold, dry air. There is a bright bonfire near the light.

    Re: New Beamshots w/ HBO200 Lamp OK, I got a crate built for the power gear. The PS does not have illuminated controls, so I put 2 sets of LED strip lights inside. 36 LEDs with 200 mA @12.5V. WAY too bright, I need to dial 'em down. The PS is angled for easy viewing, and recessed for...

    Re: New Beamshots w/ HBO200 Lamp Thinking about the testing I did last night...some not unexpected, but interesting observations: The effect of focus was greater with the SA lamp. Meaning that refocusing for every target distance made a big improvement in the shape of the spot. With the HID...

    Re: New Beamshots w/ HBO200 Lamp Power regulation would be really handy! I just double-checked the manual for my 68805. It regulates current to a user set value, with no option to regualte power. Interestingly, it DOES have an output power limit, but the latter is not user adjustable. It's...

    Re: New Beamshots w/ HBO200 Lamp Now, for reference, the original 35W HID: This one is f2.8, 8 sec, ISO100. So, it is same exposure as the HBO shot just below it, but was taken on different night, way out in the dark country:: HBO200 again, equivalent exposure, but in bright city...

    New Beamshots w/ HBO200 Lamp Ok, thanks, I see. Here's the new base - a construction tripod with spikes to stomp into the ground: Beamshots: Weather Underground says cloud ceiling is at 6000 feet tonight. Panasonic Z50 DMC-FZ200, Night Scenery auto mode. The beam appears roughly the same...

    Re: Scored a Nice 16" Parabolic Reflector. HID or Short Arc? Test Beamshots w/ HID. I experimented with horizontal running today. I can see the arc well enough to tell it was not sharply deflecting upwards. It seems a little more diffuse than in vertical running, but not drastic. I...

    Re: Scored a Nice 16" Parabolic Reflector. HID or Short Arc? Test Beamshots w/ HID. Sorry, I'm not sure I am comprehending your comment. Do you mean A.R.C. could make a custom lamp to my requirements, that will have proper fill to achieve temperature at whatever power level I need? If so...

    Re: Scored a Nice 16" Parabolic Reflector. HID or Short Arc? Test Beamshots w/ HID. After several more hours of online research, I have been unable to identify a true short arc lamp with high lumen output that will run vertically and horizontally on the Oriel gear (200W DC rated, 300W...

    Re: Scored a Nice 16" Parabolic Reflector. HID or Short Arc? Test Beamshots w/ HID. Been reading up on XBO lamps today. After hours of reading lamp specs, my effort was rewarded. Not so much by new knowledge, but by a wonderful little bit of humor added by whoever wrote this in-depth...
