Manufactured by (Unknown)
Last updated 04-23-21
Do you fly drones after sunset or before sunrise?
Concerned about FAA regulations about drone lighting?
Then the Anti-Collision Strobe (2) is just what the doctor ordered!!!
This is a small, fully self-contained, VERY light weight (4 grams!) strobe that easily attaches to most any drone.
It uses a single high-power phosphor white LEDs. It also features a rechargeable battery so it doesn't use a single microjoule of your drone's battery -- and no silly extra wiring that could become hung up in props or otherwise become a nusiance.
And it is shrink-wrapped so it has at least a minimal level of water-resistance -- fog or light rain should not kill it.
SIZE
As with any rechargeable product, charge it first (see directly below) and then you'll be ready to rock.
Affix the unit to your drone using the furnished pieces of hook-and-loop fastener -- be certain that the area you intend to fasten the strobe to is clean and dry first.
To power it on, press & hold the small black pushbutton switch for three seconds. The unit should then blaze to life.
To change to a double-flash mode, press & release the button twice in rapid succession while the unit is already turned on.
To neutralise the product when you are finished using it, press & hold the small black pushbutton switch for three seconds.
To check the battery's charge status at any time, quickly press & release the button. Fully charged, the unit should generate three long flashes of its red LED.
To charge the battery in the Anti-Collision Strobe (2), plug the larger end of the furnished USB charge cable into any USB port on a PC or Mac computer, or into a USB "wall wart" charger often used to charge cellular telephone handsets, and plug the smaller end into the MicroUSB receptacle on the strobe.
You can also charge the Anti-Collision Strobe in the field if necessary, using a USB power bank often used for charging cellular telephones. I always have an Atomic Charge Wallet on my person; a product like this is perefectly kosher.
When charging, a red LED on the product will blink; this indicates that the product is receiving power and is charging.
When the charge cycle is complete, the red LED will start long-flashing.
The Li:Po cell has inbuilt overcharge protection, so no damage will occur if you plug it into the charge and subsequently forget about it.
A full charge (from a totally flat battery) takes approximately 90 minutes; shorter if you didn't run the battery to the ground.
It is not stated how long a charge is good for.
Actually, no instructional materials of any kind were furnished with the product, so I'm kinda flying by the seat of my pants here.
This instrument is reasonably durable, but because it simply wasn't designed to take significant abuse, I won't perform, "The Smack Test" on it. I know you love to see me break things, but it ain't gonna happen today, folks.
I will also forego, "The Toliet Test" for much the same reason.
This is also not a flashlight meant to be used every bloody day, thrashed, trashed, and abused. So I won't try to drown it in the cistern ( toliet tank), bash it against a steel rod or against the concrete floor of a front porch in effort to try and expose the bare Metalmarineangemon - er - the bare Metalkumamon - um that's not it either...the bare Metalwargrowlmon...er...uh...wait a sec here...THE BARE METAL (guess I've been watching too much Digimon again! - now I'm just making {vulgar term for feces} up!!!), let my mother's big dog's ghost or my sister's kitty cats spring a leak (uranate) on it, hose it down with a gun, run over it with a 450lb Quickie Pulse 6 motorised wheelchair, stomp on it, use a medium ball peen hammer in order to bash it open to check it for candiosity, fire it from the cannoñata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piñata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piñata Central {aka. "Party Central"}), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoñata (also located at Piñata Central) is only used to shoot piñatas to piñata parties away from picturesque Piñata Island, and Mt. Erupto is an active volcano on Piñata Island), send it to the Daystrom Institute for additional analyses, or perform other indecencies on it that a flashlight might have to have performed on it. So this section of the web page will be ***SIGNIFICANTLY*** more bare than this section of the web page on a page about a flashlight that was born to be a flashlight and nothing but a flashlight.
The primary thing that piddles me off about this product is that isn't all that bright.
It certainly won't be visible from 3 statute miles.

Spectrographic analysis of the phosphor white LED in this strobe.
Spectrographic analysis of the white LED in this strobe; spectrometer's response band narrowed to a range between 440nm and 460nm to pinpoint native emission peak wavelength, which is 451.180nm.
Spectrographic analysis of the white LED in this strobe; spectrometer's response band narrowed to a range between 545nm and 565nm to pinpoint phosphor peak emission peak wavelength, which is 555.980nm.
The raw spectrometer data (tab-delimited that can be loaded into Excel) is at acs2.txt
A beam cross-sectional analysis would normally appear here, but the ProMetric System
that I use for that test was destroyed by lightning in mid-July 2013.
Video of the Anti-Collision Strobe (2) in action.
Make your drone legal for twilight missions -- the FAA somewhat seriously pooh-poohs twilight flights unless your drone is outfitted with an anti-collision strobe.
This product uses a rechargeable Li-:Po battery and does not use ANY of the drone's power. This also means that if your drone goes down and its battery pops out, this super intense strobe will continue to blink happily away and allow you a better chance at rescuing your drone.
I apologise for the poor video quality; I had to use the camera inbuilt into my cellular telephone handset to record this video; my only decent camera was on a drone which crashed and was subsequently stolen on 05-29-19.

Water-resistance could be a bit better -- but since I don't fly in the rain, this is not a negative!
CONS:
Not nearly as bright as I'd hoped (this is BY FAR what nocked the most radios off its rating!)
