Hi Tom, 

Did you use theCrazed pilot Bullet LED PAIR - Tiny High Output Landing/Strobe Lights or LED Lights  ?



 They look great but do you think they put out enough light for landing (250 lumens each)? I bet they're fine for taxiing, but landings too? The wigwag controller is a bonus too! Now I gotta figure out where to put yet another switch.

Thanks a bunch, I remember seeing your writeup before but couldn't remember where.

I don't use them as landing lights, I use the lower winglet lights for landing.

Ian,

Those lights look great for Taxy and for making your aircraft stand out as wig wag lights but they stress they have a wide beam so no, not suitable as serious landing lights.

Cheap though.

These type of lights are nowhere close to the brightness needed for landing or taxi lights.  They are effective for recognition in flight, especially when wagging but that’s it.   The fact they put the “landing light” (or even taxi) in the title is ridiculous.

I was at the hangar today and took a few pics of my wheel pant lights.  These are extremely bright (3200 lumen) cheap Chinese, loads of RF noise, meant to be bumper or roll bar mounted.  I dealt with the RF noise issues with chokes and capacitors.  These are 10 degree (spot) beams.

Originally I had them working as wig-wag lights but from a mile away, they look like one light that is on solid.  I rewired them so they flash in unison and my visibly is vastly improved.   (others seeing me of course).  I also have an LED landing light in the usual LE location.

Those $14 LED’s are rated at 140 mA, only 2 watts.  The $13 LED’s I used in my Cozy are 36 watts for the pair. They are rated at  2600 Lumens so assuming the same efficiency those Crazed lights are only about 150 Lumens!  

 

The $210 PAR36 LED lights that ACS sells are rated at 14 watts and have a rating of 10,400 Luminous Flux. Not sure what to make of that rating.

 

The standard GE Halogen bulbs are 48 watts and 100,000 candlepower (converts to 7900 lumens}; go figure……….  Maybe we are comparing apples and oranges, but I think comparing LEDs by power means something.  How the beam is focused seems important also.

Del,
I agree that power consumption comparisons are interesting for LED lights but the missing link is the rapidly improving amount of light output per electrical watt consumed.
Consider how much light some of the so called headband head-light LED things put out - and the lights on push bikes.
That said, I am not sure how much reliance to place on some of the quoted Lumens figures - some LED's with relatively low numbers seem a lot brighter than those with higher claimed outputs.
     Perhaps a manufacturer honesty measure?
I would like to replace my halogen wing tip lights with push bike LED's but the clever internal switching arrangements have made that not such a simple task.
There is another clever wrinkle to these high power LED's too - the manufacturers build in heat protection circuits which actually switch the LED on and off to keep heat within limits.
Because of the persistence of the eye we do not notice this happening but it does and it introduces RF energy to the wiring.
But when it is all added up, LED's are getting better every day and are the way to go.

It seems like y'all are finally getting around to addressing my original question. It appears in order to get to the required brightness needed for landing light, will have to deal with unwanted heat which makes using them anywhere near wing foam such as winglets a significant challenge. Which goes back to my original question, how do you deal with the heat?

I get the latest obsession of LED landing lights (like carbon fiber) but there's your local bone yard full of OEM Zenon and LED hedlamps of high quality and cheap. Bought my pair from a wrecked Mercedes and ley are awesome. And I can go to the local auto pars store for replacement parts. Done in a weekend and back to building.

I guess if one were to insulate an LED one might build up some heat.

I purchased a pair of the cheap LED lights a year or two ago. Advertised as 180 watts. Didn't want to play around with the 36 watt stuff.

In purchasing some lighting stuff last year, I found out that the sellers were specifying the total wattage, and lumens, for a pair, not each. Got to watch the slippery sellers. I was also advised that the lumens depended on the power, ie; wattage.

So I put one on my tractor. The light was exceptional. The heat was, well, absent. I never felt any heat. Note, the light was in open air, and had some aluminum fins, not much, but I'd guess there was some cooling.

These things are real cheap. Best I could say is get some and experiment. You can always find some use for them.

Another consideration is how long the landing lights would be powered? Possibly not long enough for heat to be an issue.

But, back to your question. If you find any heat build up, perhaps some ventilation would help. Not sure what would be the best, considering drag. Would want to retain slipperiness.

Now for my question(s).

I'm considering a nose mounted light.

What thickness plexiglass (if plexiglass) should be used.
Will Plexiglass when heated form (fall) into a mold?
Or is draping it over a mold better?

Going to do some playing around. Looking for some good starting points.

Well, what are your requirements?? You can get great lights at (https://www.whelen.com/aviation/category?head_id=13) but the price is high.
About the RF noise I found a remedy for that, (https://www.ebay.com/itm/20-Pcs-Ferrite-Core-Cord-Ring-RFI-EMI-Noise-Filter-Cable-Clip-for-3-5mm-5mm-7/113438674028?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2648) This took all my RF noise in the radio and made it go away. Gust wrapped the wire around the Ferite core ring and snap it closed. I wrapped it 3 times.

 They look great but do you think they put out enough light for landing (250 lumens each)? I bet they're fine for taxiing, but landings too? The wigwag controller is a bonus too! Now I gotta figure out where to put yet another switch.
 
Thanks a bunch, I remember seeing your writeup before but couldn't remember where.

Jim,

The 50 W Halogen bulbs in my winglets are what they call dichroic; the light goes out the front - the heat goes out the back;  and they DO get very hot.
They are in a sealed compartment simply carved out of the lower winglet foam , a lightweight Al bracket and a bit of heat moulded acrylic as a cover.
Behind the bulb and to protect the blue foam from heat, I have a tiny square of fiberfrax.  No heat damage in many years of use (including hot daytime use as wig wag lights).
LED lights run much, much cooler and as I mentioned earlier, well designed ones come with internal heat management, to protect the LED electronics not anything external.

It seems like y'all are finally getting around to addressing my original question. It appears in order to get to the required brightness needed for landing light, will have to deal with unwanted heat which makes using them anywhere near wing foam such as winglets a significant challenge. Which goes back to my original question, how do you deal with the heat?

Del,
I agree that power consumption comparisons are interesting for LED lights but the missing link is the rapidly improving amount of light output per electrical watt consumed.
Consider how much light some of the so called headband head-light LED things put out - and the lights on push bikes.
That said, I am not sure how much reliance to place on some of the quoted Lumens figures - some LED's with relatively low numbers seem a lot brighter than those with higher claimed outputs.
     Perhaps a manufacturer honesty measure?
I would like to replace my halogen wing tip lights with push bike LED's but the clever internal switching arrangements have made that not such a simple task.
There is another clever wrinkle to these high power LED's too - the manufacturers build in heat protection circuits which actually switch the LED on and off to keep heat within limits.
Because of the persistence of the eye we do not notice this happening but it does and it introduces RF energy to the wiring.
But when it is all added up, LED's are getting better every day and are the way to go.

Those $14 LED’s are rated at 140 mA, only 2 watts.  The $13 LED’s I used in my Cozy are 36 watts for the pair. They are rated at  2600 Lumens so assuming the same efficiency those Crazed lights are only about 150 Lumens!  

 

The $210 PAR36 LED lights that ACS sells are rated at 14 watts and have a rating of 10,400 Luminous Flux. Not sure what to make of that rating.

 

The standard GE Halogen bulbs are 48 watts and 100,000 candlepower (converts to 7900 lumens}; go figure……….  Maybe we are comparing apples and oranges, but I think comparing LEDs by power means something.  How the beam is focused seems important also.

Read the disclaimer before wasting your time and money. Fun add-on I suppose.
