I recently picked up this light at Fasttech
I wanted a light that I could keep in my work truck that would always be fully charged and ready to go. I also like the idea of being able to use this light to recharge my cell phone if I need to. There have been times when I was in a hotel room and realized I forgot my charger.
I did not remove the electronics, so I’m not posting any pictures.
Electronics:
The LED is a perfect, cool white. No pink, green, blue, or any other tint. It is mounted on a 2mm thick, 25 mm diameter aluminum board which is glued directly into the head. There is no removable pill or plate. Although I liked the LED that it came with, I wanted to try a neutral LED so I swapped it out with a T5-5A2. I was able to remove the glued in board by twisting it with a pair of needle nose pliers. It took some effort, but finally popped free. I’m not sure it was worth the effort though. It isn’t a big change and I think I liked the original LED better. 
This light uses a momentary, electronic, side switch. Short click turns on in high. Another short click switches to low. Click again to turn off. Long press at any time turns on strobe. You do have to cycle through low to turn off the light, but you don’t have to cycle through any strobe modes :bigsmile:
With a fresh cell, the light draws about 1.7 amps on high and about 0.8 amps on low. When the light is off, the driver draws 2.85ma. That seems awfully high, but it won’t matter for me since I plan to keep it plugged in and charging while not in use.
The side switch has a soft (silicone?) rubber cover. When the light is on, the cover is illuminated by a small green LED.
When the light us plugged into a USB charger, the switch cover glows green and blinks red. When the battery is fully charged, the red blinking stops and the switch just glows green. I was monitoring the charge current into the light and it does drop to zero when the red LED stops flashing, so it would be safe to charge unprotected cells in this light.
I only did a very simple test on the USB output port. I plugged in my cell phone and measured the current with an in-line ammeter. I was seeing about .5 amps and my phone charged just fine.
The light will not turn on while it is charging. The light will operate normally while being used to charge a cell phone.
Mechanical:
Machining and anodizing are perfect. No flaws. A nice, satin black finish. The battery tube threads that screw into the head are a sharp tipped, fine thread. The tail cap end has big, beefy, square cut threads. All threads are clean, lubed, and silky smooth. There are o-rings on each end, but they’re rather pointless since you have a pair of USB ports in the head. There is a totally worthless rubber flap that covers the USB ports. Every time I pick up the light, that flap just falls open. It’s attached with a tiny little rubber strip. It’s just a matter of time before it bugs me enough to rip it off.
Lens is glass. The aluminum reflector is smooth and flawless.
The beam is a typical general purpose flashlight. A tight hotspot with a noticeable corona and a smooth, bright, wide spill. Not a thrower, not a flooder, just an all around regular flashlight. A good work light for my truck :bigsmile:
Pros:
- Nice emitter color.
- Charge circuit is safe for non protected cells.
- Well made.
- Simple user interface that does not require cycling though strobe modes.
- Inexpensive
- Ability to use as a USB charger for phones.
- Can leave it plugged into a USB charger when not in use, so it’s always fully charged.
Cons:
- Cheesy rubber flap over USB ports.
- Low mode is way too high.
