I didn't think the $3.99 Flashlight that I had picked up from Office Depo would have been so great. I've been wanting one for over a year now and I could only find them for 20 bucks a pop. This one caught my eye and i bought it. Prior to purchasing this one, I also Purchased a 7th Mag Lite. I lost all the other mag lites and the one I had contained a shot bulb. I purchased the new maglite because it had a bulb in the lite, and it had 2 spare bulbs. So now i have 2 maglites with 1 spare bulb.

The 9 Led flashlite puts the maglite to mortal shame. I thought the maglite was bright but after comparing it with the led lite I wasn't far from chunking Bricks at the maglite. I can honestly say I regret buying the maglite after purchasing this led light.

Meanwhile, How long will this Led lite last? Correct me if I am wrong but I am only assuming that the leds draw 20 MA per led. Thats .18 or, 180 Millamps. The led lite caries 3 AAA batterys, Which I have estimated to be 1000 millamps. Or 1k miliamp hours.

Since the current draw is 180 milliamp hours for these leds in parallel, and the 3 batteries are in series then we come up with 1 amp hour for this battery arrangement. Or, 4.5 watts since 4.5 volts * 1k Ma is 4.5 watts. So now we have 1 amp hour or, 4.5 watt hours. The leds are 180 milliamp hours or, .81 watt hours.

4.5 watt hours divided into .81 watt hours gives you 5.5 hours of continusly operation. WOW, I can leave this sucker on for 5 and a half hours!

But, My question is.....

WHY can you not purchase these lights that can hold 3 AA batterys instead of AAA batterys. "BOTH" are 1.5 volts.

AAA 1000 MAH

AA 2500 MAH

Hrm, lets do the math. 2.5/.81 13.8 Hours of Light. Hrm.

2.5 Amps * 4.5 volts is 11.25 watts.

We know the leds draw atleast 20 ma per led, "I assume" so;

.18 for total current * 4.5 volts ,,, Hey, this means we're using .81 watt hours to run these flashlights!

11.25 watts, "(AA)" series Divided into .81 Watt hours, "what the device consumes," leaves us with 13.8 Hours of Light Operation,,, WOW.

Or, 2.5 amps / .18 ma (180 MA) leaves you with also 13.8 hours of operation.. So, Basically it doesn't matter if you calculate in watt hours or amp hours, you still get the same result..

13.8 Hours, WOW, no wonder they don't want them to hold AA batterys. They'd Last Forever.

Ever try to find an MAH rating on a none rechargeable Battery... Right near to impossible... I ride with Duracell!

What batteries is your battery of choice? My current Digital multimeter last longer with Duracell, So i've chosen it for all my applications. Any proof to make me consider another brand?
