Hey,
I have already read through martin's related question but mine is one of comparison to what I have, along with a couple of questions for the group so please bear with me
Welcome to the board. You already found a recent, active thread on your same question (basically, "What's the best H7 bulb?"); that -- and not a new thread -- is the right place to put your question, so it's been moved here.
I am messing with my low beams, tryin' to find the best look for my ride.
No. They're life safety equipment, not fashion accessories.
I currently have 100w 6000K's in
Take them out before you finish damaging your headlamps and the headlamp circuit of your car and/or cause a crash. At least one of these things
will happen sooner or later if you keep running these illegal, unsafe bulbs.
I am finding that 100w is NOT ~45% brighter than 55w (bulb-for-same-make bulb)- why not?
Several reasons: (1) Wattage is not a measure of intensity or brightness, (2) you are dinking around with poorly-made bulb-shaped trinkets advertised with lies like "6000K" (3) blue glass blocks most of the light that would reach the road if the glass were clear (4) your car's wiring isn't adequate to feed high-wattage bulbs etc.
I do like the very slightly bluer-than-white look that I currently follow from my driver's seat.
Maybe so, but that's not what your headlamps are supposed to look like. Halogen headlamps do not look like HIDs or LEDs, because they're completely different technology that produces light in a completely different way. That blue-white look you think you like, from halogen bulbs, means you can't see anywhere near as well as you need to be able to when driving at night.
Which of these would be perceptively brighter on the road
"Perceptively brighter on the road" is a whole lot less important than how well you can actually, really, objectively see. Buy
these for the best performance possible from your headlamps without ridiculously short bulb lifespan.
(Also, I've edited a bunch of unnecessary color/font formatting out of your post. Please don't do that, thanks.)
