  • A good flashlight.

    Pros: A good flashlight, which has a high quality in construction.
    A light but not too strong with a good focus, I bought three of these already and advise.
    And as the fellow said working with 18 650 (not very expensive, good durability and good size) has a fastening clip, good sealing rings with water-resistant.

    Cons: I do not have much experience in different lights have a 3 and only to such do not have much WHAT speak against.

    Other: For the price not too expensive to use and recommend to the 18,650 people who want a good flashlight with good price and with a good focus.sufficient protection against permeation of water - can be dropped into a filled bucket.
    My English is horrible this is more my opinion.

    Pros: I have several of the WF-502's. The '502' is a nice host for drop-ins. The spring steel clip is useful, IMHO. Feels good in the hand. Not too big, not too small - Just right.. Hmmm, someone could use that in a cereal ad...

    Cons: I was somewhat underwhelmed by this flashlight. This is the first 'XPE' equipped flashlight that I have tried and it may well be the last, unless someone can convince me otherwise. The XPE emitter is so small that any slight mis-alignment of the emitter in the pill, will cause havoc with the reflector / radiation pattern. This was the case in my unit. The emitter had been glued slightly off centre, which meant that it was not lined up correctly with the hole in the reflector. Even after re-aligning the emitter on the pill, the light output seemed somewhat less than the other R2 and Q5 equipped WF-502's that I own. I have a feeling that the XPE in a UF-007 style 'Recoil Thrower', would produce an interesting effect (white laser beam anyone?), but I have to say that the XPE is not as effective as a Q5 or R2 in a traditional reflector style flashlight. Maybe I got a dud, but I just can't see that an XPE emitter, with it's tiny footprint, would be able to handle 1A @ the emitter for very long, before burning up into a black lump of carbon.

    Other: Don't buy this flashlight expecting a great leap forward in technology or performance. The XPE offers a lot of lumens in a tiny package. That is it's only selling point. This emitter in a AA style flashlight with smooth reflector, would probably produce an impressive compact thrower. However, the critical point with these things is ensuring good quality control and ensuring that the emitter is located correctly in the reflector. Not an easy feat when the emitter lens is only about 2.5mm across!

    Pros: .
    + accepts drop in modules, available here
    + powered by 18650 batteries, which have good capacity for {price,size,weight}
    + sufficient protection against permeation of water - can be dropped into a filled bucket.
    + clip is fixed with screws, and appears to be rather sturdy

    Cons: .
    - XP-E R2 LED is driven beyond its specification on full brightness mode
    - no extension tube, to run on 2x18650 for increased operational time (provided an 8.4 volt tolerant driver module has been inserted). Oh well, swapping batteries isn't such a big deal.
    - tail switch rattles

    Other: 14° throw cone (12 cm/meter)
    pulls 1.3A/800mA/80mA in high/medium/low intensity mode (measured at battery when fully charged)
    through modular drop-ins, this light can be kept up-to-date with recent emitters or efficient drivers.

    Pros: Ottimo prodotto,considerando il prezzo di appena 15 euro posso ritenermi soddisfatto.
    Ottimi i materiali,la luminosità non penso sia quella dichiarata di 280 lumens ma inferiore,è molto simile alla 501b.
    Nel complesso un buon prodotto.
