[ARCHIVED THREAD] - Tank Light! (Page 1 of 2)

While browsing the candlepowerforums I found a thread on a 1kW Xenon Arc Tank Light. I don't know why, but I now need one. |
|
We have several different types of arc lamps here at my work. Xenon arc lamp hazards include the possibility of explosion and serious UV burns to the skin. Neither of these hazards are trivial. For example, you can "sunburn" the skin on your hands just during casual incidental exposure while handling/orienting the lamp. Retinal damage, retinal burning or blindness could result if the beam hits you in the eyes. |
Perfect for my application.

if you think that'll discourage anyone here you need to do a search on "tannerite".... |
In the thread he said that the power supply is 24 volts DC. This makes sense since most military DC systems are 24 volts. You would need to use two batteries connected in series to get 24 volts. Not sure how long it would last, considering the capacity of most batteries. A note about the power: He also said he thinks it's running at 1,800 wats which is pretty dumb since he states that it is a 1kW light which means 1000 watts. 1000W @ 24V means the thing is pulling just over 40 Amps. Dunno how he keeps it running on a 20 A breaker. Maybe he just hasn't had the thing on long enough to trip it. |
Maybe I can help..... About power: He said the power supply is a 1800 watt supply. What that means is that the power supply is capable of putting out 1800 watts of power. In this case, since he said it was actually a 28V 60A power supply, that comes out to 1680 watts. None of that has anything to do with the light which consumes 1kW or 1000 watts of power. If the lamp consumes only 1Kw, that is all the power supply will put out. It might also mean that the power supply consumes 1800 watts (from the wall outlet), but if that were the case, it wouldn't likely put out 1680 watts (I seriously doubt it's that efficient). Either way, it's plenty of power supply for that light. Also 1000W at 24V is not what trips the AC breaker. To figure the breaker (current) you'd have to divide the max power consumption of the power supply (maybe 1800 watts per him) by the outlet voltage (120V). 1800/120 comes out to 15A, which would only work for a short time before the breaker tripped. For safety, he should have it on a 30A circuit. This assumes the 1800 watts refers to the power consumed by the power supply. Most likely it consumes more than that at max output, but since the load is only 1000 watts (the lamp) it's probably right around 1800 watts from the outlet with the lamp running. |
Ummmm yeah, what he said.

This is bush league, you haven't played with a real light until you've used a Xenotech Britelight 7000 7000 watts of light requiring a 3 phase power outlet. We used them at NASA to simulate sunlight on the mockups. Contrary to the silly things people like to say, you won't burst into flames or get severely sunburned walking in front of these lights. It was enough to slightly warm up our pizzas though if you held it right in front of the light.  Even this 7000 watt light struggled to provide 10000 foot candles on a 1m x 1m area. That's the same illuminance that you get on a sunny day. If you've ever wondered why you can't see your surefire or even your headlights during the day, that's why. Make you realize just how bright the sun is. Although many lights can provide greater luminous intensity (Candlepower), you're still not in much danger. Most search lights have dichroic mirrors and polycarbonate shields which limit the infrared and UV light output (respectively). Bare bulb systems will put out more UV and IR but the biggest hazard there is the bulb blowing up.ETA: The headlight bit. |

Uncle_Ira Checking In! The light I have in stock is a VSS-3. It's in great shape, and is bright as hell!haveFor mobile use, a 100A alternator on a military truck should do just fine... Think it draws about 80A or so.... Thought it would be fun to set up at the annual DEFCON computer security conference in 'Vegas, pointed straight up in the sky from the Riviera, and it could be renamed "Teh Sux0r" in rodent-speak h My unit is $1350 FOB Snohomish, WA. And I DO take credit cards....... [email protected] (425) 788-0208 |
