Focus-Adjustable Cree Q3 3-Mode White LED Headlamp (3 x AAA / 1 x 18650)

Pros: This looks quite good and is surprisingly light, even with the battery. The light is very bright, low mode is still acceptable. The announce lumens seem to fit. The lamp can be shifted 90° to the bottom, so it lights up things under your nose.

Cons: The battery box is difficult to close. The focus is very easy going, might be moving by itself. The back red light is blinking, when the light is turned of and it is off, when the frontlamp is on (might be an error, should ask DX) Otherwise You have to take out the batteries if not used.

Other: If the red blinking is solved I have no complaints. It is well worth the price.

Pros: Good price, pretty good lighting. Red flashing light at the back is a good thing. The rear red light but it could be stronger. And it might blink a little faster.
Three lighting modes is also a good thing.

Cons: Box on the battery is too flat, pushing the head.
The upper gum is short, light on his head badly holds. Perhaps I have a very large head in comparison with the Chinese.
The reflector has only 3 positions. Tilting the reflector can not be set infinitely.

Other: For that price a good buy.
