Anybody out there used the Aeroleds Polaris LED nav light bulb as a replacement for the standard GE A7512-12 incandescent bulb? There are pricey but 5 year warranty and 1000 lumens out of 9 watts! Looking for a replacement to lower the running amperage when I install my skyBeacon and have to leave the nav lights on all the time.

Also it looks like a simple minor alteration with a logbook signoff per AC 43-210A flowchart. It doesn't change the basic character of the electric system and certainly doesn't change wgt/balance/aerodynamics.

Are those available for certified aircraft?

Thanks for the AML Showboatsix. I didn't realize they had one and didn't get a response from them.

I'm leaning toward the Whelen Chroma FAA/TSO. They are made to use with the existing colored lenses. The meet all the FAA specs. They are about $20 less at Aircraft Spruce and I have had great luck with hundreds of Whelen LED units on my work trucks.

I'd love to see a comparison between the Whelen and Aeroleds solutions. Someone would have to order both, put them in a plane in a dark hangar, and measure and photograph the results.

I can't do it myself, not having a dark hangar.

I have a dark hanger. You buy them both and ship to me and I'll let you know which is better :-) They probably will get lost in shipping coming back to you though!

Thanks for the offer, but those bulbs don't burn out frequently on our airplane and I have a spare. So I think I'll pass.

I have the Whelen taxi and landing lights, as well as the wingtip and strobe lights in my hanger. It has just been too cold to put them in. I also got the lens for the leading edge as the original is cracked.

Any rumors heard when the Whelen Chroma will be really available? I have good experience with their landing and taxi lights, so I am not sure I want to go Aeroleds for the nav lights.

Mid-Feb or March per Aircraft Spruce. I'm gonna wait for Sun-N-Fun and see if they have them at discount.

I had the chance to compare Aeroleds and Chroma today, forgot to take pictures :-(. Both do what they are supposed to, so my choice for Whelen was simply a matter of saving 20 bucks each.

Was there any noticeable difference between them, even if minor?

Iím not sure if I want the white lights from Aeroleds under the colored glass, or the colored lights from Whelen. Both are reputable brands, I believe.

Yes, there was and it was part of the decision making to Whelen.

Both were bright and big improvement over the old incandescent bulbs. Colors differ between the two concepts. I have old (could be original) Grimes round lenses and the result seems dependent on them. While the colored Whelens almost stay at their visible color behind my old lenses, the white Aeroleds do give a slightly altered appearance. We pulled some other Grimes lenses from the shelf and the result is different for different lenses. Definitely the light spectra of the two concepts give different results. So, I can not say anything general to the finding, only that for my old lenses the color result was more to my favor. Anybody on that decision has to check with his individual setup to decide.

Wasn't there a similar thread a longer time ago on using non-certified LEDs under green lenses turning into blueish light due to spectral features? The Aeroleds are not bad and I suspect they are still within color tolerance, so in the end it was just an emotional feeling based decision.

Thanks for the additional information!

By the way, McFarlane has the Aeroleds Polaris LEDs for $134.10 each. Aircraft Spruce has the Whelen Chromas for $127.75, so only $6.35 difference. I would choose the ones I liked best too.

Just from looking at pictures, it seems the heat sink on the Aeroleds is much more substantial than on the Whelens. Is that true when you see them in person? For very bright LEDs, heat dissipation is important to avoid long term degradation.

I did try some of the paddle style LED's when I had a 172, and the light looked fairly blue with the green lens that my plane had.

I am thinking of replacing the bulbs in my current 182 with one of these two alternatives. It almost seems I could flip a coin and do well either way.

Plenty of sources now available and most have stock, i.e. Knots2U Whelen Chroma at $124, Wilco at $125, so they all come down in the same ballpark.

The heat sinks are sufficient at both at not that different if you keep the parts in hand. In the end they all have to fit in the same existing places.
