Landing /Taxi light
 

I was suprised to see that Van's does not offer an LED landing/taxi light option. Are there any of the aero-LED systems which are well-suited to the RV-7 wing-tip installation?

Grote makes a LED that works well and it fits the round landing light kit from Duckworks that Vans sell.
The part number from vans is LL DW-02 RV-4/6/7/8
The Grote light is 638215. Napa sells them, but class8truckparts.com has about the best price, which is $116.99. Carquest had them at one time for $118.00, don't know if they still do.
Kuntzleman Electronics, Inc. @ KEatrobes.com makes a wig wag kit that works with the lamps. It is under the (LED Beacon & LTR) tab. Part number is WW.

I purchased AeroLED microsun lights for the wing tips and they fit well. Look at their catalog on the web. Also there are pictures if you do a search on this site.

The Grote has 900 lumens, AeroLED microsun is 1800 lumens, the Rigid Industries is pumping out 3400 Lumens. http://www.rigidindustries.com/product-p/62010.htm

Van's does have the AeroLEDs Aerosun lights, they are sold as part of the RV-12 lighting kit. I am pretty sure if you call them they will sell them to you. They work well for leading edge installations. The new version has 50% more LEDs than the previous version did. The datasheet can be found here:

Dean,

No bashing, but what's your take on the Rigid Industries R-Line of LEDs? they claim high lumens and fairly good throw by the looks of their little graphs...

The Rigid guys make good off-road lights, and I have met the owner, and he is a decent guy and an ex-airline pilot.

The lumen value he is giving for that particular light is raw lumens from the LEDs as specifed by the LED manufacturer. The problem with raw lumens numbers from the LED manufacturers is that they come from turning the LED on briefly when the die temperature is at 25C. Once you put the LEDs into a real world system, you lose lumens due to temperature effects, current density effects, and lens losses. In practice, the lumens that wind up in the focused beam are typically 60% or so of the raw lumens. All of the lumen values we are using in our datasheets are measured beam lumens (what is actually going out the front of the light in the desired direction). We don't use raw lumens in our datasheets because they are meaningless lab values that don't represent what the user is actually getting.

So I would just caution consumers to carefully look at the specifications as the numbers are often not apples-to-apples comparisons.

The raw lumen value for the Aerosun is 2880 lumens while the beam lumens are typically around 1700.

Thanks Dean, it's nice to get facts on numbers. I didn't realize those were manufacturer lumens either since the Rigid site expresses their lights are twice as bright as the competitors it seemed to add up that they must be 3400 real lumens. Still, i hear their products are brilliant, so i mean no ill will. Just good to know.

I just bought 2 Sunray Plus' for landing/taxi/recog lights.

Vans also sell their RV10 LED Landing Light kit. They fit well into the RV9 wingtips. A slight adjustment is made when installing.
