LED Headlights

The potential difference may be large.. but the discrepancy is still petty.

Interesting thread! I've been thinking of building some LED lights using the 9006 (HB4) bulb. During some searches, I came across these:

Has anyone purchased these? Are they bright enough to replace the stock bulbs?

Thx!,

I'm looking forward to the day I can swap out my IPF e-codes for some energy efficient leds. With all the amperage I'm pulling in Jeep (and yes, it'd probably be fine with stock lighting but I wouldnt be here if that was acceptable) I have a lot of trouble generating the power I need at rockcrawling speeds.

What sort of idle-up is available? Manual or automatic?

Warm white is where it is at, especially with SAE headlamps.

Neutral white would be okay for ECE because of more tightly controlled distribution.

Most of the automotive work with white for headlights is Neutral White. Better efficiency and better visual acuity compared to warm white.

I don't doubt that is where all the work is being done.

But, if the automakers want something to replace incandescent filament bulbs, they will need a white point of about 3500K (basically the coolest warm whites, or warmest neutral whites)

Better efficiency-of course, better visual acuity-doubtful.
