Mine is a glass lens and 14500’s work fine. Went from about 100 lumens[primary AA] to about 300 or 400 lumens W/ 14500 Battery. I got it off of Ebay a year ago
If there are glass aspheric lenses, I wonder if they are cut and polished or only molded. I suppose the plastic ones are molded and that plastic can be formed that accurately by molding, but I think you could tell molded from polished glass by how clear it is as a magnifying glass. One usually can tell how a drinking glass was made by looking at it.
That does look like a remote switch. The switch is in the tail cap that screws off, so it would be easy to make a remote replacement for it. People use remote switches for lights on guns and what not.
there will be NO diffrence between them…its a driver for nimh also…i have changed the led for xml2…its no sense…few lumens.forget it:) extremly cheap this one…
I have purchased 4 Sipik clones from eBay in the past. All were very low quality. Just received the Sipik I purchased from Gearbest today. It seems to be a real Sipik SK68. Well made and brighter than all my clones. It is also a bit smaller in size. And has a real Q5. Unfortunately I paid a lot of money for it. It broke the bank. I used my Gearbest points to ease the pain a bit. $2.61
It's just a roll of the dice when it comes to buying flashlights sometimes you win other times you lose.The gearbest Sipik Sk68 I received is well made and has a very good tint. I won.
