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.

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 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.

Here's the pic. of the speed brake gas strut replacement for those horrible springs. I did this at least 10 years ago and it still works fine. I hadn't looked at it in all that time and had forgotten how simple it was to do using all the existing hardware. Don't ask me details about the strut - I can't remember.

The spring in the pictures look like screen door return springs that are easy to get at Home Depot or Lowes.  I got one from Lowe’s last month that I was going to stretch out and wrap around the exhaust under the carb heat muff.  It broke in three places as I stretched the spring.  I then purchased one from Home Depot that was a different brand.  I was able to stretch the new one without breaking.  I don’t have the packaging anymore but it’s clear that some brands are making very brittle springs.

10 or so years ago I substituted those nasty springs with a gas strut on a friends LongEZ. . I can't remember exactly how I did it. I know it's been working fine all these years. I'll get a pic. of it in the next couple days. Most people have gone to the electric actuator setup and it saves a little weight.

The brake should blow shut above 95 kts to prevent structure damage.  That closing pressure is to be controlled by length of the slot in the floor NOT by adding monster spring tension.  Study the geometry.  The push rod and the linkage should never be near straight or ever over center.
 
If your brake doesn't blow shut by itself at 95 kts then the floor slot is too long - shorten the slot so as to limit forward travel of the push rod.  That lowers the required spring pressure.  The plans spring is PLENTY strong.
 
Spring wire is sensitive to scratches and is more likely to break when scratched by pulling pliers that have slipped off the end of the spring or by folks that have attempted to reform the hook on the end.  An excessively sharp bend  increases the chance of spring failure.

Howdy Joe, you mean the Sweetwater FSDO?? I'm right on the border between what used to be the SA and the Fort Worth FSDOs before they went to the N. Texas / S. Texas setup they have now.  There was a LOT of difference between those two FDSOs in the past and I assume this applies all around the country..

 Now, as for TSO equipment required in an experimental aircraft, this is about the same as the FAA enforcing an AD compliance on an experimental, it can't be done and I do have this on a very good source who wishes he could do something about the VE/LE nosegear fork.
  If I had a DAR (and I have assisted DAR airworthiness inspections) start to invent requirements like requiring TSO parts on an experimental I'd certainly find someone else and  at least put the word out about that particular DAR.. For that matter there are some certificated aircraft that don't require TSO parts.

The spring in the pictures look like screen door return springs that are easy to get at Home Depot or Lowes.  I got one from Lowe’s last month that I was going to stretch out and wrap around the exhaust under the carb heat muff.  It broke in three places as I stretched the spring.  I then purchased one from Home Depot that was a different brand.  I was able to stretch the new one without breaking.  I don’t have the packaging anymore but it’s clear that some brands are making very brittle springs.

Long-Ez Speed Brake spring tension

Filipe Rosa
 

Hello,
Does anyone have an idea of the tension in each spring of the speed brake? I was measuring the tension on the speed brake itself as per the plans, speed brake open and was getting around 30lb of force and was pulling the springs in order to get the 40lbs. The springs were around 4" from the attaching point when one just broke. Does this happen to someone?

Thanks,
Filipe

Great, congratulations Steve,
Like finding an old flame - as pretty as ever!
Your spec. looks good, resisted the starter, etc..  Is /will be fun.
With the shutdown I have been thinking of bringing mine home for a bit of TLC, but does she really need it, Naa!

Yesterday I did the second first flight on my VariEze.  The first was in July 1981.  I flew N118SJ for over 1400 hours including ten trips to Oshkosh from California and it was my ride through the 21 years it took to build my Defiant.  When the Defiant was flying I decided to retire the VariEze and it sat in the back of my hangar for 14 years.  About two years ago I really needed a project and decided the VariEze needed to go into restoration.  A new paint job on the fuselage, new (overhauled) O-200, new instrument panel (no screens) and electrical system, new brakes, and adsb.  I decided to keep the original concept of light and simple so I left off a starter.  I did install an alternator since it now has two electronic ignitions (Pmags).  I had flown nothing but a Defiant for the last 15 years but sitting in the Eze felt familiar and it took very little time to start feeling comfortable again.  I did several high speed taxi tests then took off.  I stayed in the pattern at Leesburg, VA which is under class B at Dulles thinking it was a good idea in case of engine problems on the first flight but it all went perfectly.  It needs a couple of adjustments like trim springs but she is a flying machine again and now the fun starts.

Oh, oh -- I know. The Lubbock FSDO.
Remember, each FSDO is individually owned and operated.

Franchise, like McDonalds, eh? :-).

Yes, like most on this forum I obviously have too much time on my hands.
