Wing tip LED Strobes (Copied from CruisairForum)

I REALLY like the Aveoflash specs and design and the price point is excellent compared to Whelen. I vaguely recall some requirement to have separate power runs for the strobe and position lights. Is that true and how does that work with the Aveoflash lights?

That brings up another question for us.. How do you run those new wires? How can you be certain they are secured?
I still say a good comet flash alternating top and bottom is the way to go if you really want to be seen.
 
I have replaced literally every wire in my plane. The original wire in the wings was only fastened in a couple of places so when I pulled it out, I had taped the new wires to it and they came in as it went out. I fastened them the same place as the original wires with cable ties. A bigger problem than wires is the pieces of mud from wasp nests in the wings. Randy, the wing man at Bellanca told me not to worry about the few we couldn't shake out. He said the vibration from the plane will eventually break them up and they seem to disappear.

I have not gotten to the Aveoflash distr at LVK yet, and alas, I will be in Florida and miss the flyin. I did speak to the distr about the how many wires thing and he said run however many you want, but with just one you will get nav and strobe or nothing. (In our case there must be two since no ground return in the wooden wing).

As an elex engr, I have thought up about a hundred ways to overcome that. The question is what can you do in the way or relays, etc. that would qualify as 'owner supplied equipment'. A good thing bout the Aveoflash units is that they run on any voltage from 9 to 32 volts. With a dollar's worth of electronic parts the size of a stack of a couple of nickles, you could have the nav come on at any voltage, but the strobe only at 11 volts or higher. The panel switch would select the voltage to put on the one wire ( a couple of diodes would provide the lower voltage). Another choice would be a simple aircraft panel dimmer switch to vary the voltage...on/dim gives you Nav, on/bright gives you both nav and strobe.

Living very close to A/S west, I've walked-in many times and can attest that their CustServ people are in-house.
But I must say most, but not all, of the folks there are order-fillers and warehouse types, not really airplane folks. They're great but would be equally proficient at Autozone.
The LED bulbs are still new, have seen limited demand, and the manufacturer has had less success with on-time deliveries to their vendors than most.. makes it hard for distributors to predict ability to fill orders.
Sometimes being an early-adopter to new tech has its drawbacks :D
 
I have been in Aircraft Spruce here Southwest of Atlanta several times (why waste shipping money if I can sign up someone for instruction to cover the fuel... :) ) and generally I find at the front desk the same person that talked to me over the phone. I haven't asked for a pilot certificate yet, but they can hold easily a conversation about "aviation things" and they seem to understand terms and situations.

Of course I am not the brightest bulb in the Chandelier either...
 
Well, to really beat up a dead horse...I saw an ad for LED nav lights...these were previously discussed, but now I see that they are tso'ed. The 7.5 watt lights are NOT sufficient for nav lights on certified planes (except for the tail light). According to the following A/C spruce link, the 30w bulbs are TSO'ed:

I inquired if these were suitable bulbs to use in my Whelen A429 nav/strobes and I have included his response below. I would have to continue to use my existing strobes, as these LED lights are approved as nav lights, but not anti collision lighsts, according to my discussion with the mfg. So, has anyone used them? I could sure use the extra amps that I would be saving.

Hello Larry;

The most popular combination for your Whelen A429 is the Sextant kit (ACS # 11-11987) navigation and strobe light system.

You can go to http://www.aircraftspruce.com/menus/el/strobes_navstrobe.html to order.

In my kit comes 2 clear replacement lenses, which replaces your existing red and green lenses.

The existing Grimes bulb is about 620 lumens and draws approx. 3 amps. My red replacement light is 665 lumens, while the green is 1155 lumens and both draw <855ma.

Thank you for your interest in my products

The Canadian ( read Chinese) uncertified 7.5 watt LED NavStrobe bulbs I bought from AC Spruce
are basically mass a mass produced LED 12v AUTO Bulb replacement. ( see AliBaba website for generic Chinese anything)

What the guys in Canada seem to have done is have some small factory in China add the flasher chip .

1 of my lamps failed after only 10 hours of Testing !!!!!.. Plus :roll: :!: :idea: :mrgreen: the light pattern is all wrong for Nav Lites.

Add to the Trash Heap of History, not your airplane !!
 
Larry L, just read your post about TSO'd led bulbs. Interesting.

The things I got.. certainly do not have the required directionality to be decent Nav Lights. IMHO.
Humble because I haven't visually verified that in the dark.

I'd like to see the TSO'd ones.

The reduction in current draw if nothing short of amazing... as all LED lights are.

so with our 25 AMP max generators, and old wiring, this is nothing but gravy.

The lamps I bought barely fit in the existing nav lights.

But if they used CREE devices... they could make blindingly bright lights in a small package.
 
Well it turns out that A/C Spruce told me that while they are built to the TSO, he does NOT have TSO authorization, so they are not really legal unless you get a field approval (at least in my case) because my A429 lights were field approved and they went thru FAA approval. So, I guess it still comes down to can you get them approved or are you just going to stick them in and worry about it if you get ramp checked or...
One person at my airport did not use the clear lenses, so they are not that obvious...Since I don't fly that much at night anymore, I am not so sure that I am going to spring for a set. Also, I have to pick my battles to getting approvals.
 
I just got word that NavStrobe now claims to have FAA approval on SOME versions of their
LED strobing Nav Bulb replacements.

Check with AC Spruce of the NavStrobe website, and get their TSO'd rabbits foot from the same company. :mrgreen:

:D
