Silvar stars and cool blue headlights

When you are figuring AMPERAGE capacity on wire, you have to de-rate it by ~25% (.707) for DC current. So if #12 wire is good for 20 AMPS AC and #10 wire is good for 30 AMPS AC, then you are looking at 15 AMPS DC and 22.5 AMPS DC respectively. Make sure you use a MULTI-STRANDED wire....not solid wire. Multi-strand has higher current capacity per given guage. :lecture:

BLUTO :)

question!!

how many watts can the IPF wiring harness handle?? can you put those 100/170 watt bulbs on there? or do u need something else? how about those wiring harnesses on ebay? how many watts can those handle?

A few weeks ago my '88 got the IPF treatment: Harness, lenses, and the 170/100 clear bulbs. (went from Hella E code with blah 60-55 DOT bulbs) Huge improvement! I said this 4 years ago when I first got E codes & 100/80 & built a harness. :wow:

Time will tell if my harness can hang with 170/100. (the 100 low isn't a worry) With how I use them - intermittent high at night- I expect it'll do fine.

does anyone have any experience with those JDM MTEC buls that they sell on ebay? the claim 90/100 watts producing 170/(150/160).... is this too good to be true? or what? or are they just trying to sell bulbs? they too also have the yellow tinted bulbs for weather driving??

I had the amber versions in a Toyota that I owned. The were bright to look at, but the light thrown on the road was much dimmer than I hoped. Might be better with an aftermarket lense to focus it better :guitar:

easy enough to figure out. . .

(just on a beginning side nite the IPF harness comes with a 30 amp fuse...but that doesntnecessarily mean the 12 gauge wire that came with it is up to the task. . .lets see)

wire is rated by amperage

so first you see how many amps you will be drawing:
170watts X 2 headlights= 340watts/12volts=28.3amps

now figure about say, 10 feet of wire (to and from battery/lights/relays)

now check the wire table:TABLE CALLS FOR 10 GAUGE WIRE!!!

looks like the 12 is a little undersized for this application unfortunately

what if we figure on 14 volts though... then we might figure on about 24 amps...STILL TOO SMALL

i was honestly a little dissappointed in the ARB/IPF MOO2 harness. . .
i was hoping for 10 gauge wire in this thing. . .

for the price i certainly could have rigged a better one myself...

so, in answer to the question, i would say yes, you COULD run those bulbs, however, you will be losing a fair amout of juice in HEAT in the wire.....
this will result in dimmer lights, and you run the risk of (possibly, but not probably) cooking the wires
*that was sort of my disclaimer ;)

just my $.02

For the money, you can't beat the Silverstars. I have em and I am happy with them.

:thumbup:
 
I put a set of silverstars on my girlfriends xj about 2 months ago, and it made a hell of a difference. Whenever she drives behind me at night it is bright as hell. For the money, its definately worth it.
 
Being one of the top technicians for the government agency I work for in the field of lighting for airfield operations and aviation, I am required to stay up to date on all advances in the lighting industry. Here is a thread that goes into a little detail about the new blue or high intensity lighting available today.
For all who are interested in the subject, Enjoy.

Quote from another thread I posted on 11-28-03:

"Well, I'd be reinventing the wheel if I tried to conduct experiments... Rensselaer Polytechnic Institute's Lighting Research Center has done a bunch, and there are a pile of SAE papers written to show for it. Very good reading with lots of insight:

www.lrc.rpi.edu/programs/transportation/index.asp

While these experiments don't offer a direct comparison between 'bulb A' and 'bulb B' they offer up some comparison between HID and halogen...using existing european spec (E code) lens designs"

I may be underwired (with the IPF M002 harness), but I love the output from the IPF 170/100 uncoated H4 bulbs. Life span is likely to be less than optimal, but that's TBD.
