I did a test this evening. My girlfriend was my assistant and she was a great help!
I was testing my NEW/UPGRADED OSTS TN31mb-470Kcd!!!
I wanted to get an idea how much throw and the effective light it can display at a decent distance. So after thinking about it awhile I got an idea of a great, simple and probably a common way of testing a lights ability to "Throw"!
The Golf Course a mile from my house!
Ok,,,Par 5, 585 yards, straight as an arrow with Three[3] Eighty[80] Ft. high Norway Spruce 15 yards directly behind the Green!
THESE ARE THE TARGETS!!!
TOTAL DISTANCE: 600 YARDS/548 meters
I went to the Tee my girlfriend stayed on the putting Green facing the Norway Spruce Trees. I do not think there was a question of "If" it was how much light will illuminate the Tree!
The rest of this are just estimates as far as "How much Illumination and how intense".I would think there is a way to test the "Intensity" of light at a certain distance. I improvised as you will see below!
Barb had my Olight M22 so she was not left in the Dark! It also served another purpose in regards to "Estimating" how lit up the Trees were as far as light intensity[brightness].
When I came back I shined the M22 approximately 30 yards From the Norway Spruce and went through the Three[3] modes and asked her which Mode came closest to the intensity of what she saw the OSTS TN31mb illuminate upon the Tree.
She said the Medium mode which is 250 lumens looked very close/similar to what she saw when I was 600 yards away with the OSTS TN31mb!
What all this means as far as a reader visualizing,I have no idea! I guess you have to have an Idea of what an Olight M22 on Medium[250 lumens] looks like from 30 yards when shined on an 80 Ft. Norway spruce at a 45 Degree angle!!!
She also said it ENTIRELY LIT UP TWO OUT OF THE THREE NORWAY SPRUCE TREES when I held the torch STILL! These Trees are approximately 80' tall and probably 30'wide! :thumbsup:
I do not know all the math and physics of light traveling. I am guessing that this tight and narrow beam expands considerably when it is "Thrown" at far distances?
In the final analysis I was very impressed with
Quadruple "M's" [MICHAEL the MASTER MODDER MINISTERS] Masterpiece,,,hey that could have been "Quintuple "M's"!!!
Side note: I also brought my Olight M3X and was very happy that it also illuminated the trees from 600 yards,not as intensely, but it illuminated it.
It was somewhere between what 20 lumens[low] and 250 lumens[medium] looks like on my M22 from 30 Yards!!! Lets say 100 lumens!
I know this is not very scientific!! I do not have the instruments or the know how to calculate what I saw,,,,,,just a creative, visual interpretation!
EDIT:
Some additional information.
This test was conducted on Level 6 [Max]. Next time I will do the test on Level 3,4 and 5. I do not think Level 3 will make it[hope I am wrong!], I suspect Level 4 will have a chance and I would bet on Level 5 making it to the three[3] Norway Spruce Trees!
-I did the test the prior night[Level 6 only] by myself and was most certain that I saw the Three Norway Spruce light up as I waved my torch from side to side. I wanted absolute verification so I brought Barb for confirmation!
-I have Golfed here over 100 times. The owner lives a driver and a Nine[9] Iron from my house which is approximately 400 Yards away!
-I DID GET PERMISSION TO DO THIS!!!
-I wish I had technologically advanced Video and Photographic equipment to record the event. I would imagine that in order to capture light traveling 600 yards it would probably be best suited to do by Helicopter!
