Landing light options

There is a a piece in the Aviation Consumer that arrived yesterday about HID
lighting. I can't regurgitate it in detail, but I remember they said the
Lopresti was far and away the most expensive, but the Lopresti kit was very
complete and made the install easier. The other brands made some kind of
shortcuts on the certification that allows them to sell cheaper. I think they
liked the 50 watt versions, I'm not sure which brand.

That is the standard warranty of all hid lights, including RMD and knots
2 you. The Lopresti tips, for my seneca at least place the strope in
front of the light, as well as my aft faceing white nav light. Strobe,
nav and aft white are all one unit on my plane.

PAR 46 hid lights are comming down the pipe and are twice the brightness
of the 36. That would be the thing to get if your going to go hid. with
hid you get very little current drain. Three amps on the par 36 size.
Guessing about 6 amps for the 46?

I am putting two quarts lights on my nose strut. They are used very
little and probably better.

IMHO, the LoPresti Boom Beams are much better. They are warranted for 5
years or 5000 hours and deliver 5-7x the light of a standard aircraft
bulb. These lights are standard on every Cirrus Design and Lancair
aircraft so LoPresti must be doing something right...

I installed the RMD HID lights, with a field approval (they're STC'd
only for the RMD wingtips, I mounted them on the nose bowl of my
Skylane). Installation was a cinch.

I went with the RMD lights because they're the same product, but half
the price, compared to the Boom Beam.

Those suckers are BRIGHT.

And, no filament to break. They're warrantied for thousands of hours,
just like the Boom Beam.

Just curious: Do you fly with them on all the time?

The rmd wingtip lights look nice. I didn't see any pricing
info on their web site. I wonder how expensive these are.

Yes, you will need to phone him. He is a real good guy to deal with. He
makes tips for knots 2 you people so doesn't advertise much. I bought
tips for my seneca with hid lights in the tips. I leave them on for
inflight recognition lights. i didn't really need new tips but I wanted
the light. The lights in my older tips really wern't much good in daylight.

In searching and reading you prior posts, I see that the
GE H7635 is a halogen 12V, 50W PAR 46 lamp that should
fits into the GE 4537 mount. Looks like bulbs.com has them
for $14.95. I think I'll try one of these.

My 1976 C172M had the same problem. Cessna has or at least had a kit
that stiffened the lower nose bowl and changed the resonant frequency
of the assembly to move it away from the resonance freq of the lamp.
It takes a couple of hours to install the honeycomb and glass cloth
but it has worked for more than 20 years on my plane. Before
installing the kit my landing light would not last more than 3 hours
on or off. Now it lasts for years.

the landing light (12V, 100W). It is mounted in the lower cowling
under the prop and does not last very long. I suppose the vibration
of the engine kills the life of the bulb. I sure wished Cessna had designed
this landing light installation to allow for replacing the lamp without
having
to remove the cowling. What a pain to replace a light.

I've tried the "rotate it 90 degrees in the holder" trick, but could not
tell that this helped any.

Many people recommend the Quartz Q4509 as a longer life replacement
for the GE 4509 PAR36 size lamp. A best as I can determine, there is no
Quartz version of the 4537. If you have seen these, please let me know
where.

Any other suggestions for a replacement lamp for a GE4537 lamp that
might prove to have a longer life?

Hi John,

Well, that certainly is good information. I've never heard
that before. If you have any idea of the kit number or service
bulletin number for this mod, I'd appreciate hearding about it.
So far, searching on Google has not turned up any information on
this.
