The Alphaelite Flashlight
Specification Sheet
Maximum Lumens: 1000
*almost certainly not
Battery Type: 18650 Li-Ion (2)
Battery Lifetime: 800 Cycles
*some batteries do last this long, just not the batteries you can buy with this light which tend to last 10 to 100 recharge range.
Run Times 2600mAh: High: 4 Hours, Med: 12 Hours, Low: 38 Hours
*if true max= 343 lumens
(2600mAh*2 Li-Ion/4hours = 1,300 mAh/hr. Cree spec sheet shows 357lumens@1,000mA, 502 lumens@1,500mA. If we take a close estimate as a proportion of current difference, that = about 24 lumens per 100mA over 1,000mA, which = 429 max lumens for this light. Next, you lose 10-20% lumens in most lights to glass and reflector, but this is a tulip edge which eats up more lumens, so if we give it a MASSIVE under estimate of losses and say its –20% only, its a max of 343 lumens.) This is ONLY if its a T5 bin cool white (which it probably isn’t, so its probably less) and ONLY if the driver is efficient (which it probably isn’t with a cheap driver) http://www.cree.com/~/media/Files/Cree/LED%20Components%20and%20Modules/XLamp/Data%20and%20Binning/XLampXML2.pdf
*unfortunately this light comes with Ultrafire batteries, so if those runtimes are gotten on inferior lower capacity Ultrafire batteries, it is likely this light only produces 100 to 200 lumens max.
Run Times 3400mAh: High: 6 Hours, Med: 16 Hours, Low: 44 Hours
*see above
LED Driver Board Maximum Forward Current: 2A @ 3.2V
*Math doesn’t work here, plus Li-ions are 3.7V and so the driver should not be running on 3.2V
LED Emitter Type: CREE® XML2 T-6
*Probably not, most cheap lights have T5 emitters or worse. And now there are fake Crees out there with even worse specs, which is very likely in this light.
LED Emitter Lifetime: 50,000 Hours
*see above…who knows how long the fake Cree lasts
Modes: 5 High – Med- Low – Strobe – SoS
Variable Lumens: High: 1000 Med: 600 Low: 300
* NOT a chance, NO way and NOT likely even for high in this light.
Zoomable: Yes
Lens Type: Aspheric / Convex
Beam Angle: 5º – 120º Max
Maximum Usable Spot Beam Distance: 776 Feet
*unlikely unless you like to see through a tiny square of dim blue light at distance in low light.
Maximum Visible Signal Distance: 2,316 Meters
*see above
Body Type: Aircraft Aluminum
*aluminum is used in aircrafts, so technically sort of correct
Color: Black
Belt Clip: Yes (removable)
*had a cheap one like this which bent easily and became unusable
Wrist Strap: Yes (removable)
*had a cheap one like this and it fell apart rapidly
Switch Type: Tail Cap
Weight: 226g without batteries
Operating Temperature: –20 to 60°C
*not with Ultrafire batteries thats for sure
