What are the relative power ratings? Are they quite different?

Sorry to revive the nearly dead horse, but...
I'm also looking at strobes and wing wiring, and am
also confused.
Yes, the Aeroflash are not as bright, as they put out
only 10 joules per flash -- half or less energy than
the Whelen. but they cost half as much... Wasn't it
Bob that commented that the regs require 20+ joules
per flash (based on the "400 effective candles"
wording)??
My question is:
Does the Airworthiness Cert. (Operating LImitations?)
declare that the aircraft is equipped to fly at night,
or does it say that it can be flown at night IF it
meets the lighting requirements. And how do the
Aeroflash units satisfy the requirement (some of
theirs are PMA), if 10 joules/flash isn't enough??
I've corresponded with the people that make Nova equip
-- emer vehicle power supplies, strobes, etc --
reasonably priced. (strobe.com, strobesnmore.com)
They're very interested in entering the non-certified
plane market as an alternative, but they need to know
the requirements.
Is there a simple explanation.??

The instructions refer to both. In my installation, I have both the
power and ground wires to the power pack and the output wires from the
power pack to the flash tubes running in the same conduit with servo
wire bundle.

It is both wires and I guess I'm more concerned with the stobe output
wires to the flash tube. I have the strobe wires grounded per the
instructions. (Ground at the power pack, not connected at the flash
tube end.

I am looking at the Nova too, specifically the Nova Micro-Pak. See it here:
http://www.strobe.com/products/micropak.htm
I am liking it because it looks like it is smaller and lighter weight, yet
only draws 4.5A. It is a plain-jane powersupply without a lot of unneeded
stuff.
I believe Bob said you need at least 20 Joules per flash.

Yes, but as I understand it, these supplies would send
too much power to the Aeroflash strobe heads that can
only handle 10 joules. Which begs the question: Are
all the Aeroflash units blinking out there technically
legal?? Or shouldn't I be asking??

Bob,
I have a question about the PIDG Crimper from B&C.
I have an AMP ratchet crimper I got at Sun & Fun. It's jaws are about 1/8
wide. Will I get the same results with this, or do I need to spend the $40?
Regards,
John Slade

Try a smaller bypass . . . 100uf is a tad heavy. A 10uF tantalum
would be about right if you want to put it right in the crowbar
ovm. Solder (+) to SCR anode, (-) to SCR cathode.
Alternatively, tying the 100uF capacitor to another protected
feed from the bus would be beneficial to both the OVM and
other devices in your system.
Bob . . .
Thanks Bob for your response. It doesn't sound like your too surprised to hear
about these false trips. I'll try your suggestions.

I like Strobes n More for strobe kits. They well both Whelan and Nova power
supply kits. I like the 90 watt 4 head x-pak with free switch and harness
for about $270. Includes four light heads complete with amp connectors and
4 x 15' power cables. I've been looking at these for a couple months now
and haven't seen anything that looks better so far for my money.

But Larry.....what about the streamlined lenses for an airplane wingtip.
It's not clear from the "strobesnmore" website, but it looks like their
bulbs are just that - bulbs, with no lens covers. We'd have to fabricate
some kind of cover. This issue has been holding me up buying from them.

I am building an RV7 with enclosed wing tips. The strobe lights will fit, I
plan on it anyway, in there fine and not require additional cover. I may
need to come up with some type of form/structure for holding and attaching
the light bulb in the enclosed area of the wing tip. I will buy position
lights (for the red and green requirements) and a Whelan combo light for the
tail position. The x-pak should drive the Whelan tail light even though
different name brand. Nova and strobes-n-more use the same amp connectors
as Whelan. I will post my final results and thoughts on this after
installation.
Thanks, Neil, for pointing out your issue as it may be an important
consideration.

The Rotax 912 does not require battery power to run - only to crank the
starter. The ignition modules are energized by what is essentially a
magneto ( or even two ) colocated with your alternator.

Jim,
Our airplane is powered by a Rotax 914 that DOES RELY on an electric main
pump to keep running.
Few people are aware of the fact, but the 914 IS electrically dependant.
