It looks like a Mag.
It feels like a Mag.
It smells like a Mag.
But when you turn it on, this vivid white light pours out the end, instead of that sickly dim yellow "light" produced by an unmodified Mag-Lite.

The Corona Blaster uses three C cells to feed a white Luxeon III LED at the bottom of the reflector; the light can be adjusted somewhat by turning the bezel (head) clockwise or counterclockwise.


Use the Corona Blaster like you would use an unmodified Mag-Lite. Press the rubberised button on the barrel until it clicks and then release it to turn the flashlight on; press and release it the same way again to turn the flashlight off.

For momentary (signalling) use, press the button less firmly (before it clicks) and hold it that way for as long as you need the flashlight on; release the button to turn the flashlight off.

The beam is somewhat adjustable by turning the bezel (head) clockwise or counterclockwise.

To change dead batteries in your Corona Blaster, unscrew & remove the tailcap, dump the dead batteries in the nearest garbage can (or the dead battery box, if your community has a battery reclamation program), and load three new C cells in, button (+) end first. Finally, screw the tailcap firmly back on. Done with that, fun ya!!!

Measures 684mA on the EverActive cells it was supplied with.

I don't normally punish loaner samples, but I was given explicit permission to do so here...BRB...ok after ten smacks against the corner of a concrete stair (five against the tailcap, and five against the bezel), no visible damage was found, and no optical or electrical malfunctions occurred either.

When that dreadful suction test was performed at the rear portion of the barrel, no air leakage was detected. So this flashlight is completely weatherproof at very minimum.
I cannot perform that dreadful "toilet test" here, as the commode is shared by two other individuals.
But yes, it appears to be water-resistant and weatherproof as long as the bezel is attached.

Speaking of which, you can unscrew & remove the bezel and stand the Corona Blaster on its tail to use it in candle mode. You will lose some water-resistance in this mode, so don't place it directly under the drip in a leaky tent when used this way.

Sample was sent to me by S.A. and was received on 12-22-04.
This may be a loaner, unless I choose to purchase it later.

UPDATE: Same Day: I have purchased this flashlight, so I no longer have to return it.

VERY IMPORTANT!!! S.A. has no affiliation whatsoever with Mag Instruments. He modifies these flashlights himself, and is not in any way compensated by Mag Instruments.

UPDATE: 08-13-06
I have decided to name this flashlight the "Corona Blaster", after the attack mode that Beelzemon uses near the end of Season 3 of the TV program Digimon.

Here's the Corona Blaster (the real thing).

UPDATE: 08-28-08
I have come to learn that Stephen (the creator of this wonderful light) has passed on after an illness (he passed away August 25 at 11:50pm), and is now "enlightening" angels in heaven.
Although I never subject this unit to any significant abuse, I'll be "babying" it even more now.
