100/90 Watt H4 Bulbs

Is anyone running the 100/90 watt Halogen H4 headlight bulbs (24V) in stock SBU Headlights? If so have you had any issues with overheating?

Thanks in advance for the input.

I tried this kind of "upgrade" in Grand Cherokee, some time ago.
Not a good idea, got some electrical problems because of that (nice smell of burning wires too).
Check this link though.H4 24V 75/70W TRUCKSTAR by OSRAM

I have them in my Mog and love them.They're as good as they say they are.

You could upgrade with heavier wiring and relays, but I would think that 90W low beams would piss off oncoming traffic. I run 55/100W bulbs in 7" Ecode housings and the light output is awesome.

Yarr,
I was looking at the 75/70's too. Glad to know you like them, maybe I will use them instead of going for broke (possibly literally...)

Needamog,
Good point. Last thing I need is to run over an oncoming ford festiva when she swerves into my lane!

Upon further review, I think these are the right bulbs for the stock headlights. And they come in a 75/70 Halogen.

Looks like the ticket to me.

Make sure that is the correct bulb base. It looks different than a standard H4 in most modern housings. My 416 factory housings required that style, do SBU's use it also?

Quite right, this is not an 9003 (?) type H4 bulb, this is a direct replacement for the 55/50 watt bulbs that were in my 1300L truck (maybe others, but it seems each mog is different).

Do you guys get the Philip +80's H4's over there - they are a standard 55/60W but the same light output as 100/130W. I had some on my Landrover and they were great. I tested them with a light meter against the 100/130W I had and they gave the same result when the engine was revved to 200rpm but at idle they were 1/3 of an F-stop brighter. They only lasted about two years when one died followed by the other one a month later - seems like they burn quite hot and die out a bit quicker.

I've been looking for brighter bulbs for my 1300L as well. So, have you actually installed them in yours yet? I want to buy a set of those if they fit. I had thought about changing lights all together, but for now if these bulbs will work I'll make do with them for awhile.

Have not installed yet, I just ordered them today. Delivery from the factory is 2 weeks, so it will be a bit before I get them installed.
