A couple of folks here wanted a "Sneak Preview" of the System I have been working on. It should be wheels up by SHOT (01 Feb '08).   Many more images here: polarion-usa.com Select "Videos" and "CSW-Images" Made in the USA. Same 4000+ Lumens It will feature remote switching for the gun operator (ON/OFF), remote power choices from multiple sources including D/C vehicle power, readily available Military 5590 Lithium Sulphur batteries and their rechargeable counterparts the 2590’s, as well as the Polarion Lithium-Ion batteries. The system will quick connect and disconnect for gun-mounted or handheld applications on the fly. The system will have 80 minutes of onboard power emitting 4,000+ lumens of clean, brilliant white light. 850 nm IR Filter, all aircraft-grade aluminum body, modular connectors and cables. Best to everybody. |

There is no "easy" comparison and I don't know what the exact answer is. It a nutshell: Candela is a measure of intensity, Lumens is essentially volume. You can have high candela and high lumens. You can have high lumens and low candela You can have low lumens and high candela if the reflector collimates the light to create that high number It what you do with the volume that creates the actual beam signature. The lumens rating of the Polarion is Lamp lumens, what the lamp is producing, not what is projecting forward after reflector/glass inefficiency is factored in. To get that you need very controlled conditions and an integrating sphere. As I am finding out this is deep tunnel when trying to get precise information as there are many factors that skew the numbers. Back to candlepower/candela: I would estimate at this point, based on others folks testing of the lowered powered Polarion X1, this light is actually in the 375 to 400K candela range. Most 1 Million candlepower (candela) spotlights are nowhere near this number as in a total fabrication of the truth. As far as other lights it's just best to do head-to-head comparisons in the same conditions using the same camera setting from the same position. To get down to details: I suggest you read this thread located on Candelpowerforums: www.candlepowerforums.com/vb/showthread.php?t=186173 In practical terms, if the moisture content in the air is not too high, the Polarion can reach out and spread light laterally in generous portions in 400 meters+ range which is quite useful for searching unaided by optics. |
