The Sunwayman Revolution Variable Intensity LED Flashlight (hereinafter, simply called the, "Revolution") is a small LED flashlight with continuously variable intensity -- the dimmest settings can be stared directly into with no discomfort, while the brightest setting can almost set fire to nearby dead plants & trees!
Before you power up this little fire breather, lock the kids upstairs and put out the dog...hmmm...locking the children in ***ANY*** room isn't a very good idea, and putting out the dog would also be a poor idea because it isn't on fire...but you know what I mean!
It has a Cree XM-L2 phosphor white LED at the bottom of a stippled ("orange peel") reflector protected by an AR (antireflective) tempered glass window, the body is aluminum (or, "aluminium" for those across the pond) with a Type III hard-anodized finish, and is powered by a single CR123A lithium camera cell.
SIZE
To use the Revolution, press & release the tailcap button to turn it on, and rotate the knurled ring just under the bezel (flashlight head) counterclockwise (or, "anticlockwise") to brighten it and rotate the same ring clockwise to dim it.
To neutralise it (turn it off), just press & release the tailcap button again.
MAXIMUM INTENSITY MODE MUST BE LIMITED TO NO MORE THAN 5 MINUTES (300 SECONDS)!!!
This is the first time that I've encountered a FLASHLIGHT with a duty cycle recommendation.
To change the power cell (battery) in your brand spanken new (or corroded old) Revolution, unscrew & remove the bezel, carry it to a bridge over deep water (the Oakland Bay Bridge would be ideal; however, the Juneau-Douglas Bridge would also do in a pinch here), and throw it over the side so that it goes "blub blub blub" all the way to the bottom of Gastineau Channel with all of the bowling balls that were lobbed over that bridge in the 1950s and 1960s...O WAIT!!! THAT'S THE GOOD PART!!! So just set it aside instead.
Tip the used CR123A cell out of the barrel, and dispose of or recycle it as you see fit.
Slide a new CR123A cell into the barrel, orienting it so that its nipple-end (+) positive faces outward.
Screw the bezel back on - and there, you're done.
Aren't you glad that you didn't throw that bezel over the side of the Juneau-Douglas Bridge now?
This is what the Juneau-Douglas Bridge looks like...or what it lookED like anyway before it was replaced in 1976.
And this is what the bridge looks like now.
Unable to measure current usage due to how the product was constructed.
Because this is a loaner, I will not strike it against a concrete stair, try to drown it in the loo, stomp on it, run over it, try to cut it up with a knife, or otherwise abuse it like I might abuse another flashlight. So this section of the web page will seem more bare than this section of the web page on a page about a flashlight that does not have to be returned or passed on.

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.

TEST NOTES:
Test unit was sent by J.P. of London, UK and was received on the afternoon of 05-07-15. Unit needs to be returned, so the, "" will be appended to its listings on this website, denoting the fact that the the unit needs to be sent back to London and that it will be spared, "The Loo Test" and, "The Smack Test" as I'm certain that Jahn will want to receive it with no dirty lavatory water & desiccated rat pellets in the barrel and no dents or dings in its body.
UPDATE: 00-00-00
PROS:
Extremely bright for its size!
Continuously variable intensity
Small & compact size
Water-resistant and submersible to at least 1 meter
NEUTRAL:
Battery it needs may be locally expen$ive (a decade ago I saw them being sold for $28.00 a pair!)-- purchase them online if possible
CONS:
It has a duty cycle recommendation at maximum intensity -- which is kinda queer for a flashlight...a FLASHLIGHT for Christ sakes!
But it still earned a five-star rating from me as this little flashlight roXXorZ ('rocks' in 1337 5P34K!!!
