The 2in1 Super LED Lamp consists of a white LED flashlight and a red laser pointer wrapped up in a small, handy-dandy package that is small enough to carry on your keychain.

It comes in an all-aluminum body, and feeds from three LR41 button cells. The LED has a continuous on/off switch, and the laser pointer has a momentary on/off switch.


SIZE



To use the product, remove it and its included batteries from the package first. No knives, scissors, or other sharp instruments are necessary. Feed it (see below), and then you'll be ready to rock.

Press and release the rear button to turn the white LED on. Press and release it again to turn the LED off.

Press and hold down the front button to turn the red laser pointer on. Release the button to turn the laser off.



To feed baby, unscrew the tailcap and remove it, and throw it in the garbage can...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

If necessary, dump the three used LR41 cells out of the barrel and into your hand, and dispose of or recycle them as you see fit.

Stack three new LR41 button cells on a counter, table, or other flat surface, button-end (-) negative up.

Lower the barrel of this product over the cells, and slide it to the edge of the table or whatever. Place your thumb or finger over the end of the barrel so the cells don't just fall out of the barrel and clatter all over the floor. Once you have the product over the edge, invert (flip over) the barrel and your finger or thumb at the same time, so the open end of the barrel faces up.

Remove your thumb or finger, and screw the tailcap back on.
There, you're finished. That wasn't hard, wasn't it?
Aren't you glad you didn't throw that tailcap away now?

Due to the way the product was designed, I was not able to take current usage measurements.



This instrument is reasonably durable, but because it has a laser in it, I won't do the smack test on it. I know you love to see me break things, but ain't gonna happen today, folks.

Water-resistance is minimal at best. When the tailcap was removed and the barrel was suctioned, air had no problems whatsoever passing through the product. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of siamese cat pee (what - no cat box?), slush piles, mud puddles, tubs, toilet bowls, cisterns, sinks, fishtanks, dog water dishes, or other places where water or water-like liquids might be found.

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 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 2in1 flashlight/laser to smell like seaweed or piss when you go to use it next. Besides, salt (from seawater or wee-wee) can't be very good for the insides.

Product is properly labelled as a laser device; it is labelled to emit less than 5mW of laser radiation at 650mW, making it a CDRH Class IIIa laser device. Actual laser power appears to be very close to the 5mW limit of a Class IIIa device, and appears to be approximately 640nm in wavelength, not 650nm as the label indicates.

As you can see, it is just below lasing threshold, even when the batteries are strong enough to operate the white LED.

TEST NOTES:
Test unit was purchased from a Candlepower Forums member on 05-06-05, and was received on the afternoon of 05-09-05.

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.
