Default That's about right.

$18 each. The converter will power 10 of them. Since my main intention is daylight anti-collision rather than night flying (FAA says no night ops at my strip) I may opt for crazy bright. Will either be 2 or 3 per wing.

Default All in.

Just ordered 4 more of these things after testing the first two I got. 11000 lumen landing lights for $ 1/10 AMU was too attractive to pass up. My _only_ regret will be the extra 8oz of weight from 3 Cree heads per wing vs. 2 (and one per side would've equaled the vintage incandescent landing lights of old.) Now the month long wait for shipping from Hong Kong begins anew.

Planning to wig-wag them with Perihelion's wig-wag module (add $88) so I don't have to add hi-watt load resistors to get an EL13-A2 module to work reliably. Anyone know of a downside to this? Looks like it would save weight and wiring complexity.

If I ever hit a bird or plane, it WON'T be because they didn't see me coming These things leave spots in front of your eyes for quite awhile.

They work fine wig-wagging with a solid-state (mosfet switching, no relay) EL13-A2. Last ones I got on ebay where a buck or two. I have a schematic somewhere.

Default I can't find those...

all searches reveal mechanical innards when I look closely enough. Can you point me in the right direction, Bob?

Thanks!!!

You can take these apart and put a different value of capacitor to adjust the flash rate to be slower. Its just a simple 555 timer circuit.

Default One problem, I think...

I'm looking to wig and wag, not just flash

Hey Bill,

Refresh my memory; don't you have a HAM ticket?

For quick&dirty, that flasher could feed a double throw relay to get your wigwag function.

Charlie

edit: ebay search for 'led wig wag' turned up:
https://www.ebay.com/itm/LED-Strobe-...JY297y&vxp=mtr
and a bunch of other hits.

"If I ever hit a bird or plane, it WON'T be because they didn't see me coming."

I would have to agree. As I've mentioned in one of my earlier post in this thread. Someone had posted a link to a Quantes Airlines study regarding birdstrikes and wig wags. They put wig wags on some of their commercial jets and found they had a 10-50% reduction in bird strikes in those jets. I don't know how they came up with their numbers.... still promising none the less.

I have the Baja Designs spot LEDS. They are incredibly bright. If I were to hit a bird with these puppies flashing away, well I'd have to conclude the bird was simply committing suicide!

Default Now, Charlie...

I looked at the Crazed Pilot offering yesterday. Floating grounds required, possible mechanical hardship isolating the lights from the mounts. Less current capacity than the Perihelions, but still some headroom as mine will be 3.6A per side.

My ham ticket didn't include everything else in the Popular Mechanix buffet - just good ol' analog / vacuum valve theory. Remember the 80's? Hybrid rigs were cutting-edge.

Still researching what's out there. I have another month to wait for the rest of the flashlights to arrive.

Default oh, well....

Bummer on the floating ground issue, but might still be worth exploring.
