Coast® LED-Lenser® 360° Bow Site Illuminator, retail $9.95 (http://www.flash-lights.com...)

Last updated 09-25-06

This is the 360° Bow Site Illuminator. It features a NUV (near-ultraviolet) LED at the end of a flexible gooseneck-style stalk.

It comes in an all-aluminum body, covered with a Type II anodizing for protection, and feeds from three AG5 button cells.


This product is ready to use right out of the package; batteries are included and already installed.

Press the button on the barrel and hold it there to get light; release pressure on the button to not get light.

The 360° Flexible Bow Sight Illuminator has a flexible metal neck, which you can position as you see fit to direct the NUV radiation wherever you need it.

To change the batteries when necessary, unscrew and remove the tailcap, throw it to the ground, look at it all funny, cock your head like a puppy that doesn't understand what it had just been told, and stomp on it with old or used golf shoes...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Tip the used AG5 cells into your hand, and dispose of or recycle them as you see fit.

Insert three new AG5 button cells in the barrel, button-end (-) negative first. Screw the tailcap back on, and be done with it.

Another way to do this is to stack the three button cells on a table, counter, or other flat surface, button-end (-) negative up. Lower the barrel of the product directly over the stack of cells, and slide the whole affair to the edge. Place your thumb or a finger toward the open-end of the barrel so those batteries don't just clatter to the floor. Invert (flip over) the product and your thumb or finger, remove your thumb or finger, and screw the tailcap back on.
Aren't you glad you didn't stomp on that tailcap now?

Check to be sure the illuminator is not on now; turn it off if it is.

Current measures 19.9mA on my DMM's 400mA scale.

This product appears at least fairly durable, and it is. When I beat the urine out of the poor, innocent 360° Bow Site Illuminator (fifteen whacks against the corner of a concrete stair: 5 smacks against the side of the illuminator head, 5 smacks against the side of the top of the barrel, and 5 smacks against the side of the tailcap), only the expected damage was found. There is some minor gouging on the side of the illuminator head and the side of the top of the barrel where it was struck. No optical or electrical malfunctions were detected.

There is a black Type II anodized finish over all of the exposed aluminum; this should help keep the product looking newer for longer, even if it goes up against coins, keys, or flashlights during carriage or storage.

The product is not very water-resistant, and is DEFINITELY not submersible.When I removed the tailcap and then performed that dreadful suction test, a significant air leak was detected. There are no environmental seals (O-rings) visible on it, so water, milk, diet Pepsi, coffee, urine, root beer, or other liquids could get inside. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of wild boar pee, glasses of milk, slush piles, mud puddles, tubs, root beer floats, toilet bowls, cisterns, sinks, cups of coffee, fishtanks, dog water dishes, old yucky wet mops, wall-mounted porcelain urinators, or other places where water or water-like liquids might be found. A little rain or snow probably wouldn't hurt it though, so you need not be too concerned about using it in lightly bad weather.

If it fell in water and you suspect it got flooded, disassemble it as you would for a battery change, dump out the water if necessary, and set the parts in a warm dry place for a day or so just to be sure it's completely dry inside before you reassemble and use it again.

If it fell into seawater, got thrown into a glass of milk, fell in a root beer float, or if somebody or something peed on it, douche all the parts out with fresh water before setting them out to dry. You don't want your illuminator to smell like seaweed, sour milk, or piss when you go to use it next. Besides, salt (from seawater or urination), lactic acid (from moo juice), or sugar (from root beer & ice cream) can't be very good for the insides.

The dominant wavelength appears to be approximately 395nm; this was verified via spectrometer.

Wavelength is too short to be measured with the instruments at my disposal.
Color is a dim, dull violet, not the bright magenta as depicted in this photograph.

The security strip in a $20 bill.
This strip is significantly brighter & more obvious in reality.

Test unit of this flashlight and 4 other products were sent by Steve of www.flash-lights.com and were received mid-morning on 04-12-06.

Product was made in China. A product's country of origin really does matter to some people, which is why I published it on this web page.
