New LED headlight designs

[redciv1]

I get the LED light phase we are going through now, however LEDs just don't seem reliable enough. I can't tell you how many semi trucks I see with LEDs missing or blinking. If they replaced the LEDs on this setup with something else I think they would be more reliable.

It's all about quality.
In my day job, I'm (among other things) a lighting specialist. LED's aren't a "phase we're going through", any more than fluorescent was. But it's about quality.

Most people don't understand that LED's generate a TON of heat. How you manage that heat is crucial to reliability.

Don't buy cheap LED. buy GOOD LED. you'll thank yourself later.

Just to clarify (before this spins off into a tangent, lol), we are taking about source of heat. If we were to compare an incandescent to a LED, the incandescent produces a ton of IR heat (you can feel the warmth of the light) while an LED produces heat from electrical resistance and is disapated via heat sinks. Think of a processor in a computer... the chip produces no light (obviously) but churns out a ton of heat due to the resistance in the processor; same (or same-ish) thing with LEDs.

The reason people think LEDs don't produce heat (I suppose) is they think of household lighting (and incandescent vs LED bulbs)...the reason the LED doesn't seem hot is that it's consuming a lot less power. If it consumed the same as the incandescent, you could fry an egg on it.

Sorry for the interruption....lol.

Perfectly explained. Much better than I would have attempted using voice to text from my phone.! :-) haha!

so now that I'm here in front of a real keyboard, and a full-size screen, I discover how adept I am at distracting from an original topic by chasing squirrels. haha.

Sorry for that.

To bring us back full-circle: If I understand correctly, the problem with the headlights that look just like these and are sold on Ebay doesn't have to do with the LED's themselves, but rather with the construction of the housing, right? I think I read that they leak, yellow prematurely, are prone to warping in the heat, etc?

These sure look awfully similar to those.

Evything you said, and they use low quality 5mm LEDs that burn out prematurely (partly due to the quality, partly due to the fact that they are on load resistors instead of a dedicated and regulated power supply).

Perhaps we can convince these folks to whip us up a 986 kit:
