Default LED Landing Light

I've read with much interest forum members who have made their own NAV lights from Luxeon LED's. I have Duckworth Landing and Taxi lights in my -8 wings. Has anyone made replacement lights from the Luxeon high brite LED's? Seems this would be easy to do and would have relatively low current draw and long life. Think I'll give it a try but wondered if anyone else has done this. Thanks.

Default Some Issues and Ideas

Hi Jim,

I made some nav lights from luxeons and am very happy with the result. A landing light is doable, but you need some optics for the luxeons to focus the light, a way to run them at peak current, and heat sinking to carry the heat generated away. There are some off the shelf units that are nice, but spendy. C'mon we are experimental - more fun to roll our own. I sometimes end up learning stuff by accident along the way!

I have in the design/build stage a taxi light based on the newer SSC P7 LED (from Korea) that looks promising. I should have the current regulators (from Turkey - go figure) by the end of the week to begin testing for light output, heat, and noise. Right now I have about $45 into the project.

If I end up with a good result, you know I will post a complete report. If not, I'll quietly delete this post and make an pedestrian-incapacitating uber-light for my road bike.

Here is a teaser, at less than half current....

Where did you get your SSC P7 led from? I found a place here for $20 plus shipping.

For those interested the Seoul (Korea) buys part of their LED process from Cree. Cree is and has been for about 2 years, the leader in High Power LED's located and mfd. in USA in Durham, NC. Highest lumens output.

Also more output than the Lumiled Luxeon "Rebel". These are the 3 main players currently in High power LED's

Luxeon Rebel (Philips), Seoul (s. Korea) and CREE. Cree has consistantly been leading the pack for about 2 years or so.

I've heard Cree's are the best from the last couple of years of listening to flashlight fanatics.

do you know a source to get Crees in the color we need?

What color do you want / need ? We make LED flashlights using Cree XRE LED's

http://www.ledsupply.com/ for low volume buyers.

We make LED flashlights using Cree XRE LED's The highest output is about 6000K color.

red and green for position, like these:

http://www.luxeonstar.com/luxeon-iii...00ma-p-282.php
http://www.luxeonstar.com/luxeon-iii...00ma-p-281.php

if i can get something brighter, more efficient, in general better, I'll pay a little extra for Cree. I don't want to spend $30 a piece though, unless i make double sure i won't ruin them the first time i run current through them!

Arrow Don't confuse position lights with landing lights

The required intensity levels for position lights are relatively low, and they can be easily achieved with any of a wide variety of common, cheap LEDs.

Landing lights require far greater intensity levels than position lights (as well as focused beam characteristics), which are not so easy to achieve even with the latest cutting edge high-power LEDs.

Landing lights are the topic of this thread.
