Last weekend my local cpfers had a 'light show' gathering and one of the attraction was the Fenix L1 light which is similar (or same?) as this one.
Being made of tungsten stainless steel, it sure felt heavy for the size. But it gave a kind of solid feeling and also could imagine the hardy strength.
Running on an alkaline battery, it took about 400mA current. Assuming the efficiency to be around 80%, I could imagine the current flow to the Luxeon could be around 150mA which calculates to 0.5W. For this size, it sure looks bright.
As the creator of POP (PIC-O-PWM) and its variants, my hands get itchy whenever I see a beautiful host. It is perfect for 14500 with reverse clickie.
So I opened the head and found this.
The star is ground to fit the AA head, it is presumed to be RW0J. The boost circuit with a rather huge inductor is covered with epoxy. The heatsink is designed very cleverly.
Now it is replaced with POP2 sandwich board loaded with latest POP2 v2.31.
Now it runs on 14500 li-ion rechargeable with 400mA current flow at max brightness. Being a POP2 equipped light, it does regular things such as multi-brightness and strobe/sos. It should go on for close to 2 hours with a single 14500 cell at max brightness output.
I didn't have much time to take beamshots, but here is a few shots taken with max brightness. They were all taken with F2.8 1/2 sec setting.
I wish to find some time to take more comparison shots.
Enjoy.

[Edit] I was reminded that this light is actually Fenix L1+ not L1. So the title is changed accordingly.
