LED Headlights

[Martyn]

How are they at night compared to regular lights?

Pictorial comparison here:

Lights shining on a wall doesn't say a lot to me.
What view do you get on the road?

A comparison like this says much more to me.

And a small tip for the next time you take photo's for light comparison. Set up your camera for full manual settings so the settings are the same with every photo. Makes a much better comparison.

I too would like to see some beam shots, I have been curious about all these LED lights cause they dont seem to really use the reflector housing to shape the light like other lights, more that they are a diffused wash of bright light, unlike HID retros that would have crisp beam cutoff.

Each LED has it's own reflector
That the shape is more like a wash is because it are multiple parallel light sources. It's technically possible to focus them on one spot on a wall, but when you change the distance it's going to be "blurry" again.

Why no beam pics or any information of the actual lighting? What use is a picture of the lamp?

Bump, any update to this Scott?

One of the concerns -- well, maybe questions is a better word -- I have about LED main lighting on vehicles is the potential for ice buildup on the lens during cold, snowy driving. Many times I've needed the heat from my H4's to prevent ice buildup.

Scott, have you been able to measure any lens surface temperatures, or otherwise form any opinions about this?

4xdog,

Legitimate concern on the ice issues. I heard recently that cities are having problems with traffic lights with led's not being warm enough to melt the snow or ice off of them. Here's a news story about this issue. I can see it being a major issue where I live. If you have an ungaraged vehicle here the ice build up during our too frequent ice storms can be considerable. Not sure I would want LED's in that situation.

Seems like incorporating some type of heating element would be a simple solution to that problem (talking about the headlight mfg's).

Good point. Not an issue so far in Prescott, even with considerable snow and low temps. this winter. Not quite scientific, but so far, so good.

LOL. It is called a halogen bulb. It also puts out a fair amount of light.

I'd still like to get a set of these in a Land Cruiser and compare them against the common H4 upgrades.

A side note, these were also intended to be Fleet replacement for trucking companies. The whole 10,000 hours of use thing. I'm still waiting to run across someone running them.

PhulesAU --

Keep your eyes peeled. On a thousand-mile trip on the interstates of the midwest at the start of the month, I probably noticed a dozen Class 8 trucks with LED lights, and not really looking. They're out there.
