Brilliant signalling in compact, versatile WF-501B – Ultrafire WF-501B Philips Luxeon K2 Green LED Flashlight (1*18650/2*CR123A) Reviews

Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

Pros:
- Great feel in hand
- Compact
- Bright Green LED
- Good penetration in fog
- Visible 1km in clear night
- Visible 400M in daylight
- Easy to modify
- Solid case
- Fits perfectly to the SKU 01375 "Large Flashlight Holster 2-Pack"
- Durable, well built shell, no rattling
- REALLY smooth thread on the battery insert section.
Cons:
- Battery life (consequence of the size and brightness)
- Only 1 o-ring on the green one I recently bought
- Would prefer red button or some external indicator of colour as I use these in conjunction with blue, red and white variants of the same model.
- Difficult/nearly impossible to modify the tail
Other:
OK throw and good flood for such a little light. Modifications we made to one green and one red included glass optics, reflector and crown to make a thower. Red spotlight not as useful as having the flood through fog for attention, but added a lot of distance for signalling. Looked very cool as well (you've seen Starwars, right?).
Bottomline:
Less than $10 for a WF-501B. Great deal!
