Question 1

Why  does  the  seller  avoid  listing  the  lumen   power  of  this  flash-light ?????

Accepted Answer

There is no reference as to the lumens, voltage, amps nor the type of bulb used (which can also indicate lumen level) that is provided by the manufacturer. So don't assume that the answer that 800-1000 is accurate. Many flashlights in this price range are around 300 lumens but who knows for this one. For example, a CREE XM-L T6 bulb at 3.2A produces about 900 lumens with a 18650 cell (3.7 Volts).

Question 2

It is typically 3 aaa to replace an 18650. can anyone confirm that this light actually takes aa as stated or is it aaa?

Accepted Answer

These are the battery choices:
1 each 26650 rechargeable 3.7 volt lithium ion cell or
1 each (smaller diameter) 18650 3.7 volt rechargeable lithium ion cell housed in the supplied plastic centering sleeve or
3 each AA cell ( a variety of chemistries, disposable or recharcheable  ) housed in the supplied AA cell carrier.
The first option ( 26650 cell ) provides the longest operating time and lowest operating expense ( my favored solution ).
The third option, using 3 fresh disposable alkaline AA cells, provides slightly brighter initial performance due to the  higher voltage of the battery  pack but is the most expensive operating option.

Question 3

How does the focus work on this, is it a twist type or push and pull?

Accepted Answer

Push and pull - working now - impressed with wide angle / lite coverage. Great for glove compartment or using on hiking trails.

Question 4

What is the typical battery life on high? on low?

Accepted Answer

Only tested it on the high setting. With a fully recharged 26650 li-ion battery (5200mAh) on HIGHEST output, it stays bright enough(>80% brightness) for practical use for 5 hours then becomes a lot dimmer(~10% brightness) after 6 hours. Using a 3400mAh protected 18650 battery it usually gives you preferred high brightness for about 2.5 hours. The good thing about this flashlight is it can also take regular AAs although they are not as powerful and long-lasting as the li-ion ones.
In the weekend camping or night hiking scenarios, I would primary use it with MEDIUM output for longer run-time.
