IPF - Headlight Replacements RECTANGULAR part # 820H
One pair of 7" round IPF replacements were intalled with the H4-83T, Super Jey Beam bulbs. They are rated at 12V 60/55W but produce 110/90 Watts of equivalent light. They do not require an upgrade to the wiring harness and provide an incredible amount of light over standard halogen lamps.
The install process is simple. Just like changing a regular headlamp. The only note of caution is: DO NOT HANDLE ANY HALOGEN BULBS with barehands. In fact, do not let the bulb come in contact with any skin, oil, grease or french fries. When the lamp is activated it will burn out quicker if it's dirty. It is advised to use gloves, or handle the bulbs with a soft rag.
The bulbs used are the Magic H4 bulbs that have a phosphorous
ring at the base of the lamp. This ring helps to maintain
the high operating temperature and produce a brilliant light
that is very white.
The H4 replacement bulb features a high pressure exotic gas mix that provides illumination equal to 110 WATTS on low beam and 130 WATTS on high beam. But without the additional current flow, as they are only using 55 and 60 Watts!
The IPF bulb is rated at 4000 Kelvin. The HID (high energy discharge) systems found on expensive European sedans is rated at 4300 Kelvin. The technology used by IPF is as close to HID that can be obtained with current technology. For the record, a standard bulb is rated at 3400 Kelvin.
The lamp tends to have a white/blue color to it to oncoming traffic.
From the driver's seat the light dispersed is white. White and crisp. The 15 degree cutoff of the light is very European and does not offend oncoming drivers while providing excellent light distribution.
The operative word for these lights is CRISP and CLEAN.
It is also very cool that they will glow blue for up to 10 minutes after being used. The lamps also are available with a green glow, part M15. In addition, standard H4 bulbs may be used, but I don't think they will glow after use.
The cost of the IPF replacement headlights are very competitive when compared with Bosch and Hella. I have used both before and noticed the difference in quality of the IPF units. The IPF units have a thicker lens and a heavier feel to them. The quality of the lens is impressive. In both the Hella and Bosch units I've owned before I detected imperfections in the fluting and glass, not so with the IPF units. They appear to me to be of much higher quality overall. It should be noted that these lamps are not dot approved. But then again, neither were the Hella's or Bosch's I've used before. Regardless, all of these replacement headlights are an improvement over the standard headlight and all provide the European style of light distribution. ARB selected IPF after comparing other brands, I can see why they did.
The replacment H-4 Headlight units come in the standard 7" and rectangular type.
Initially I was going to use the 90/145 Watt lamps but couldn't make the special IPF wiring loom fit through the headlight buckets on my 81 300D(Fritz). So I used the 90/110W Super Jey Bulbs. These bulbs have an actual power rating of 55/60W so I can use the stock wiring. On the little wagoneer (88 wagoneer limited) I used the Marine Blue lamps. Those have a rating of 110/130 (illumination) with only 55/60 Watts consumption. While the light is clear, it's not as full as the 90/110W. I will upgrade that installation using the 90/145 W with the H4 wiring loom.
I can see again. Fritz had standard Halogen headlights before. I was running my fog lamps to help fill in the headlights. With the IPF lights I can barely tell that the fog lights are on now.
Nice white light with the typical Eurpoean cutoff. Reminds me of the lights on my European sedans. (BMW 2500) When I flick on the high beams I can see a long way down the road. I have not had a long enough break in traffic in the Seattle area to actually measure the distance they will illuminate highway signs. From my experiences with the Hella lamps in the BMW I'd estimate close to two miles. I would estimate a slightly less distance with a standard H4 bulb. The Super Jey bulbs used are extra ordinary.
The lights are available to retailers through ARB-USA in Seattle. You can contact ARB at 206.284.5906 in Seattle, Washington to find one near you.
I've written other articles on some of their other lights: http://wagoneers.com/JEEPS/IPF-lights/ In addition to lights ARB imports the Old Man Emu lift kits for Jeep Cherokees and other makes. They also provide the ARB air locker differentials.
If you live where it gets dark at night, this kit is for you.
