| Subject: | Small diameter Taxi Light Needed |
Hi Group I have a Europa XS with limited real estate on the cowl or EZ mounting
of a Taxi LED. I have a Kuntzleman 3" diameter Hockey Puck and could mutilate
the cowl and put a clear cover over it for a lot of work. BTW the angle coverage
of Kuntzleman is 2 degrees. It's just about marginal for taxi. My build partner
has a LED Headlight for his Mountain bike that is nothing short of amazing.
It has a hot spot ~ 15 degree angle and incidental 25 degree coverage. It
has a single large area of yellow LED that's ~ 1.2" in diameter. I was comparing
light from my Volvo station wagon with H7 Halogen right only headlight, Kuntzleman
and Bike Headlight. Bike headlight is whiter, brighter, better coverage
than either of the other 2. The bike mfg says it measured a precise 1,000 Lumens,
but for me it seems that a lot of Mfg kinda stretch the truth. Acid test
going out and trying it and comparing works best for me. Amazing for 1.2". The
problem is it has a control that is not conducive for aircraft. Computer controls
things including an innovative sense of current at the LED. They drive
it hard but control controls things great. It runs off a single Lithium battery.
Being very careful to try and drive LED with a driver, worked OK sneaking up
on current to match controller. When shut off upon turn on burned out LED. Anyway
my question: Does anyone know of a small LED that is ~ 1.25" in diameter
with wide angle and throws out incredible light? Probably needs the precise current
control circuit. Can pretty EZ mount 2 on cowl. Aerosun sells a small LED
but it only has a 10 degree angle. Ron P.

Bob,
I could use two of the RED high intensity bulbs.
I assume you will tell me how to pay.
To finish off another thread, if I have a 40 amp alternator and I want to fuse-protect
the B-lead would you recommend a 50 amp (or other) ANL fuse somewhere
forward, like on the firewall?
Thanks.
Mark

John,
This is a very impressive amount of due diligence on your part.
Thank you so much for sharing all of this. It will help me up my game in my own
planning.
The data on EM-5 current draw is very useful since I was using much higher numbers
derived from Ross's very conservative numbers quoted in his manuals.
Using your numbers I can see that a single large Lithium battery should give me
all of the ALT-OUT endurance I would ever need over water or mountains here in
the West.
Mark
