  • Very bright light for the money

    Very bright light for the money.

    Build quality is standard Ultrafire WF-502B... which is sufficient for most.

    Light draws 1,5 amps in high mode which translates to 520 Emitter Lumens for an XM-L T6 bin: So true to the description.

    Long run-time for the lumens: 1,5 Hours out of a single 18650 Cell is not bad at all - if you can manage the heat...


    Heat transfer from Pill to housing is insufficient.

    If you intent to have the light in Turbo mode for more than 5 min, you need to improve it: Some Aluminium foil around the pill to fit it snuggly in the body will do the trick... (true for all Ultrafire WF lights I have seen).

    UI needs some getting used to.


    An excellent compromise between brightness and run time. You will be very hard pressed to find a torch which gives more Lumens per watthour...


    Excellent value for money, excellent Lumens per watt, but some rework required.
