Still not bright enough, I bet.

It may be irritating to some since the LED low beams are about 5,000K and the incandescent high beams are about 3,000K. Thus, they appear to be very yellow in comparison.

No, they are fine for fog lights but worthless for high beams. Also, the very broad light source from so many LED chips makes them very difficult to accurately focus and project. Ideally, you want a point source of light.

Understood. But what are you going to want when you really need those high-beams? Matching color, or light output?

Light output wins every time for me. My Acura has HID low beams and incandescent high beams so it has the same color temperature difference, but unlike the Leaf, the high beams light up the night like twin torches due to very large and well designed reflectors. My BMW was the same way.

I would concur with others that the reflector design is at fault.
How much power did the replacement bulbs consume in comparison with the Leaf's stock ones?
I have never measured to power usage of these bulbs, but according to their description, they consume 65W (like the stock bulbs). Here is their advertisement blurb:
  • Rated at 4000 Kelvin and illuminating 120 watts of light from only 65 watts, these bulbs emit a brilliant Xtreme cool white light that lights up road hazards and signs long before a normal halogen bulb.
They do seem to illuminate a bit better than the stock bulbs, but it’s probably due to a slight increase in light output and their whiter color temperature.

Having sold PIAA products for years I can tell you that the claims manufacturers make rarely translates in the field. It has a lot more to do with efficient reflector/projector housing design than bulb output.

The LED may work OK for a high beam application since you are less concerned about beam pattern. Although with the LED's spread all over the place vs. located where the halogen filament once was, I bet it will look bright from the outside looking in but not so bright from the drivers seat since light is scattering everywhere. I would buy it from amazon then return it if they suck. THey will send you a UPS label for the return freight.

If you want a more effective high beam I suggest swapping out the rather worthless fog lights and swapping in a pair of 55w driving beams (long and narrow beam) and then have the relay triggered by the high beam wiring.

Here's the data on the OEM high beam bulb

Philips H9
Germany 1B04.B
12V 65W 12361

Spec sheet

So 2000 lumens for the US (DOT) model, if I'm reading the spec sheet correctly.

Amazon lists it here. Funny, a customer is saying it's brighter than his stock bulbs.

At least one thread in Candlepowerforums says all H9's including this one, are about the same.

I wouldn't bother with LEDs for fog light, they are just not bright enough for the price. HID conversion is easy

I am reading all these posts about upgrading this bulb and that bulb, Does anyone have a comprehensive list on bulb upgrades with part numbers and outlets?
