It dawned on me I have two flashlights with XLM led bulbs in them - 100Lm per watt..
1 flashlight has 1 XLM t6 bulb in it the other full size flashlight has 3 XLM t6 bulbs.
1st small flashlight uses 1 18650 li -ion battery the larger one uses 3 18650 batteries.
The bulbs run on 3A max and put out a true 100lm per watt.
the bulbs rating is 10w = 1000lm
Both flashlights are ridiculously bright, I kid not i have never encounter such a bright flashlight as my 3x XLM t6 bulbs and the other little 1 bulb flashlight is way brighter then normal flashlights, I estimate it is 5 to 10x brighter then a AA Mag light when directly compared.
