18650 Battery vs Normal AA Size Battery

  • sheepish Top 10 Forum Poster Sunday, August 23, 2015 6:46 AM Reply
    There are some Sipik SK68 torches amongst the products I linked above, but the SK68 is normally under $10. It's a pretty good 1xAA zoom torch and available in a range of shell colours and LED tints (and LED colours).

    I would suggest avoiding any Zhishunjia brand lights. They seem to lie about the specs of their lights more than other brands.
    NO! I don't know why DX screwed up the site so badly.
    Ask them.

    Any comment on this item?

    The shell is a nice colour.

    In the extra photo included in the product details, the enlarged photo of the LED is an XP-G, not an XP-E. (I'd report it if Report Error was working.) However, the LED actually looks like an XR-E, and it is said to be an XR-E in the specs. That is an older LED but still OK, just not as efficient as some newer ones. They can develop an intermittent fault when they have been used for a few years.

    It is rather unlikely that you will get anywhere near 260lm with an AA, since that would require a battery draw of 4-5 A. I would expect no more than about 140-160 lm, and much less out the front because of the zoom design. That's still a pretty good amount, and easily usable for general usage, especially with the versatility of the zoom function.

    It's a nice package for the price.

    Good choice Clement. I've bought 5 of these for myself and friends and everyone is happy! They are solidly built and probably as good as single AA zooms get. Lumens are the most lied about subject in advertising on any Chinese site, and the likes of you and I wouldn't know what one looked like so just ignore it! Feel secure in the knowledge that it is plenty bright enough for most general use.

    The only weakness I found is with the zoom. with two of those I received, the heads were flopping around loose, because the O-rings they run on were not properly fitted. They are very thin and tucking them back in requires some patience and care. Apart from that, no complaints.

    Dear ozOzo
    Thanks. I have this similar item which I purchased about 2 years ago in my country. The problem is the on/off button behind intermittent failed. Do you foresee this problem may occur on this new one?

    I haven't had that problem. I wouldn't think they are any more likely to fail than any other. The “Clicky” type switches are most popular nowadays, usually on the tail cap, because they are most suitable for multi-modes. Many are replaceable but I'm not sure about these.
