If you go to a store look at most of the electrical lighting, flashlights on the market, you will find that most manufacturers use lumens as their units of output. The amount of lumens is a fixed number while the candle power can be grossly inflated by simply concentrating the beam by adjusting the focus. Fewer and fewer light manufacturers are bothering to rate their products with candlepower since it is outdated and inaccurate for their measurement of light output.
The human eye responds most strongly to light nearest the 560 nanometer wavelength, which is a yellow-green color. Some manufacturers dramatize light output measurements by using candlepower units. They can get away with this because light measurement terminology is unfamiliar to most people.
But the basic concepts can be explained as follows: The science of measuring light with respect to its effect on the human eye—which responds differently according to the wavelength, or color, of that light—is called photometry. Photometry includes measuring light intensity in a particular direction (in units of candlepower or candelas) and total light energy in a particular situation (measured in lumens).
With illumination tools, a candlepower measurement doesn't necessarily indicate total light output. To illustrate this, imagine representing a flashlight's total light output as a bag of sugar. If you pour the sugar onto a table to form a cone and measure the cone's height (representing the brightest part of the flashlight beam as measured in candlepower), you still wouldn't know the total weight of the sugar (representing the total light output as measured in lumens). Conversely, if we shake the table so that the cone settles and becomes rounded, the sugar's weight (lumens) would be the same but the height (brightest part of the beam) has been lowered and spread out.
Now take half the sugar from the demonstration above and put it inside a narrow conical container taller than the loose conical piles we made earlier. Even though this narrow cone's height (candlepower measurement) is greater than the previous cones, it contains only half the sugar (lumens). Reflectors and lenses are analogous to that conical container because they can create a light beam with a high-candlepower "hot spot" that sounds good in advertisements but tells nothing about total light output or light distribution within the beam.

You have made my point, and quite well I might add, thank you! :-)
I want a headlight that has lots of sugar in all the places I want to see, and not just in one spot. Regardless of the total lumens (and yes I want lots of them), if it isn't spread across the entire field I'm interested in seeing (and nowhere else) , then it is of little value.
I appreciate the explanation -- you need not explain too much photometry to me, I got my physics degree likely before you were born ;-)

LMAO...as far as getting your physics degree before I existed well guess again! you probably didn't even reach puberty while I was already walking the face of the earth. Keep reaching!!!

duhhh...I didn't know you have a physics degree geeezzz I wasn't up to your standard! yeah I expected a dickish answer from you regardless of the BS we have posted in this thread bottom line is the other posters and myself have disagreed on your earlier post as HIDs having zero impact on forward visibility and no difference from the standard bulbs.
I appreciate your trying to knock years off my age, I can only wish... ;-)

HID fog light kit for D r/t
Just installed HID fog lights with the 35w 5000k HID kit from DDMtuning. Seems like they are making these from China, b/c I have recieved the kit from...well, China. DDM office is however, in CALI. I bought from them last year, and they were sent from CALI. Oh well, as long as they warrant their warranty and the HID kits function, I have no problems were it's shipped from.
I also bought the "Error Code Eliminator" kit....which is NOT NEEDED. Please read again...the error code eliminator kit is not needed for the HID to function. In fact, the error code eliminator kit caused the fog lights not to function. At first, I thought it was me wiring it wrong and the fog lights would come on randomly and not when I want it to. So, today I took off those error code eliminator kit and the dam HID fog lights work!!!!!! No error codes or anything....just bright as hell fog lights.....LOL!!!!

Is the polarity reversed on the fogs? I know you know don't need the ECEs on fogs but you'll probably need them for lows, right? I ordered my HIDs from ddm tuning as well and they shipped them from china as well. I'm in the waiting process to receive them. Hopefully by the end of this week so I can have a weekend project.

Thanks....I mounted the ballasts behind the bumper with 3 strips of Velcro and zip tie for ease of mind. Just clean the surface w rubbing alcohol n ur good to go.
