Smaller side by side photos located in post #3
After receiving my TD-15X today, I began to wonder about the supposed 20% drop in output going from two 18650's down to one 18650. So, I charged up my two Redilast 18650's (2900) and took some photos.
Not wanting to intrude on ManChow's great thread, I decided to post these photos on a separate thread.
There are three sets of three photos. Each set is in this order: TD-15X (2x18650)TD-15X(1x18650)Olight SR50. The settings are the same for every picture; .5 second exposure, f3.5, ISO 800 @ 18mm.
(Sorry about the slight aiming issue from picture one to picture two in Set I. This makes the second photo appear perhaps brighter. It isnt.)
Set I:
Set II:
Set III:
************************************************** ***************************************
I also took a couple of more photos that include more than the TD-15X; I wanted to do a ceiling bounce test of some known lights and their output as compared to the TD-15X.
So, I took photos of five lights in my bedroom, as they projected light bounced from the ceiling. Again, the settings for each picture were the same; 1/4 exposure, f3.5, ISO 800 @ 18mm.
All the lumens numbers come from the manufacturers websites.
Olight SR50 (supposedly 800 lumens):
Malkoff Wildcat V2 (supposedly 750 lumens):
Lumintop TD-15X 2x18650 (supposedly 580 lumens):
Lumintop TD-15X 1x18650 (supposedly 464 lumens - 80% of the above 580):
Fenix TK15 (supposedly 337 ANSI lumens):
Especially in the last five pictures, you can see that the lights are what I claim they are. Each flashlight was loaded with batteries that had less than five minutes of total runtime on them.
What do you think??
