Default Over wattage H4 bulbs? Feedback?

So light output is **** on the EKs, I've considered HID and projector casings, hovewer neighter will give a quality beam for a reasonable price.

There are a few bulbs out there that claim a good power output such as the Phillips Xtreme but they run about 60$ CAD a pair and probably dont compare to actually running more power to your lights, a halogen can only be so efficient.

I'm not planning on ghettoing this, I will run new 10Ga wire from the battery and use relays. My only worry is the increased heat output on the lense as well as which bulbs to get.

I know APC makes some, but somehow I doubt they are good quality....

I would not use high-wattage bulbs in Civic housings, mainly due to the heat issue and the risk of melting them or at the very least degrading the reflector and lens over time, but also because of the potential for over-powering the optics and causing problematic glare (not unlike what occurs with drop-in HID kits). You can pick up a set of X-treme Power bulbs for approximately $52.00 CAD, and when you factor in the price of high-wattage bulbs and the upgraded wiring, you'll be at nearly the same total cost.

I was under the impression that drop-in HIDs had horrible light distribution as they didn`t have the correct geometry and therefore weren't at the focal point of the lense.

That is part of the problem, but even with kits that come very close to the stock focal point, the halogen optics are simply unable to properly distribute the additional light. Basically, the halogen housings are designed to make the most of the relatively limited light being provided by the H4 bulbs. When you increase the amount of light, the result is increased levels of glare, hot spots, and an overall poor beam pattern. The effect won't be as pronounced with high-wattage halogens because they are precisely built to the same dimensions as the factory H4 bulbs, and they do not create as much output as an HID capsule, but it still won't be ideal for public roadway usage. Even the X-treme Power is probably nearing the limits of what should be put into the stock Civic DOT housings, since (as you're aware), they aren't particularly good. If you were dealing with something like a halogen E-code headlamp, you'd have much better light control and could benefit more from higher-output bulbs.

Yeah, I read about those.


Still wondering if anyone's ever tried the 90/100W bulbs?

Neither are particularly good compared to other bulbs that are available, especially considering the cost.
