View Full Version : LED Runway Edge Lights

Just browsing a couple of airfield lighting web sites and noticed they are marketing LED taxiway centreline and edge lights. But could't find anything on LED runway edge lights. Now i;m talking about permanent lights, not portable battery powered ones.

Have LED runway edge lights been made available yet. If not how long till they are developed enough.

You could manage that. Have each light as an array of bulbs. One bulb = dim, twenty = bright. But from the looks of things, LED's are already here in the UK. I'd swear that the "wigs-wags" at LCY are LED's.

I wonder whether the problem is getting the necessary brilliance (i.e. candelas) out of LEDs.
