H-4 LED vs. HID
The SI unit of luminous flux is the lumen (lm). One lumen is defined as the luminous flux of light produced by a light source that emits one candela of luminous intensity over a solid angle of one steradian. In other systems of units, luminous flux may have units of power.
Has anyone tried the 102 LED H-4's? The LM (lumens) on a 102 LED is : Type: H4 Voltage: 12V Color: white LED qty: 102 Luminous flux: 350LM Color temperature: 5500K Lighting angle: 360 degrees Lifespan: 50, 000 hours Were the as HID is : Voltage: DC12V Power: 60/55W Lumen:95/85LM So if LM is the the intesity of light then could the LED be brighter? and thus project further down the road? http://www.eshop111.com/ebay/xpicsc/tbz441c.jpghttp://image.pushauction.com/ViewPic...96&H=360&W=480 |

The trouble with LED isn't that they don't produce lots of light output. The trouble is that the output is difficult to focus and project over distance. If you were already running a projector retrofit then the LED bulbs would be worth trying. With only our stock reflectors however, I don't think they would be useable for anything other than show.
