IPF Headlight Conv..
I don't know why everyone keeps refering to these lights as blue. They run at 4400K, so it is on the yellow end of the light spectrum. Most HID Off-Road lights are in the 4200-5000K range, and they would be much bluer, but somehow work better.

I dont give a wit about the color, I just like the beam pattern 200% better than the stockers, white or bluish bulbs dont matter to me one way or the other.

Regarding blue-tinted bulbs, check out this build thread.
ARB loaned Bruce their Jeep a couple of weeks ago but I never did find the rep to talk about lighting. Pity.
The Jeep was done up pretty nicely though.

They have a blue filter on them to try and look like HID; it has an adverse affect on their performance.The next generation of HIDs won't have the bluish cast to them and the temperature will be closer to 3200K, a color that actually works.
Hopefully it will be "cool" for people to run regular bulbs after that.

The blue arc is not what creates the blue tint to an HID, as if this was the case then you wouldn't see the spectrum range of them. It is the gas that the bulb manufactuer uses that determines the color. There are companies out there making off-road HID lights and they typically will run the 4200-5200K on the driving and spor lights, and run closer to the 3200K area for fogs. It is all about what makes it easier to see under the conditions they are baing used.
I know that now at this point usually you go into the loss of power due to wiring. In the JK with the pulsed width modulation system they are not sending a consistent signal. If you measuer at idle then yes it looks like there is a huge power loss. If you measure while the Jeep is moving at highway speeds all of a sudden that dissapears. However most people don't tend to measure with an ohm meter at 70 mph, but rather they will measuer with the lights turned on parked in their driveway.
Many of the things you read online from Daniel Stern, and the candle power forum need to be taken with respect to what they are looking for. Daniel Stern is mostly concerned withhaving the best poor weather performance out of a headlight. I would rather have the best performance out of my headlight for daily driving conditions, and use a quality fog light and auxilary lights for the poor weather performance spectrum.

Littlejon,
Having had and run them all, I'll take an HIR or pair of H7s over an HID for headlights any time. Maybe it's because there's so much fog and humidity where I live and I'd feel differently in Arizona ---- but I feel that I'm more likely to depend upon my forward lighting to save my life when the weather is nasty.
You probably already know that I tinted my HIDs to selective yellow per DS's suggestion.

My personal prefrence however would be to have my headlights work best for what we drive in most of the time, which in most of the country is dry roads. This is what the beam is set up to work best on for any headlight wether it be an e-code or not.
The poor weather conditions is where the auxilary lights start to come into play, especially on a lifted vehicle. For a Jeep you would want to have your poor weather (rain, snow, fog, whatever) lights down low and wide. This is where you would want a beam to be selective yellow, or a light that has the appropriate gasses and shape to be yellow.
I know that I have a few different things I am planning on trying to change the stock fogs into a better light to achieve this (possibly modify my fog holders for an HIDX or Baja Designs 4" light with a yellow lens/filter with a wide driving pattern) in order to acheive the best lighting possible to have for any condition regardless of the weather.
