  • Real glass lens

    posted by haste45 on 15:49:47 G1T 29/01/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: This is a real glass lens. It is fat and thick with lots of magnification. It really focuses the light from a 10W LED well. It throws a nice beam. I use it together with a reflector. The lens stays cool even if the LED gets hot. Glass quality is pretty good.

    Cons: Don't drop it as it will break, because it is real glass, but I guess that is obvious. It is a bit heavy and bulky for a flashlight, otherwise nothing wrong with it. It had a tiny scratch on the surface, but it does not affect the light at all.

    Other: Buy it!

    posted by NiBaa on 09:42:35 G12T 22/12/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Nice focus for 4000 lumen 50W LED. Throws light much longer distance than without. Produces bright ring of light on the wall. Fits nicely to my reflector (sku39974). Glass not plastic! Very clear and smooth glass.

    Cons: None actually, bit heavy though. But glass is!? Actually I',m noob with lenses cause I can't say anything wise here, but why I would complain about something that does not make sense.

    Other: Really worth of its little price. Does its job quite well.

    posted by gugusse on 07:33:31 G11T 02/11/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: It focuses perfectly the LED, even if you have a really strong beam of 80° you still have a little light outside this angle.

    Cons: I received the lens with a little black spot on it (less than 1mm). It didn't change how it works and it is not annoying at all so i didn't make a request about it.

    Other: A very useful product for a little price. I didn't realize how 80° is a small angle so make sure you need it and no something wider.

    posted by jannewal on 14:11:09 G10T 29/10/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Good price, good optics, solid piece with very few visual flaws in the glass

    Cons: Fixing it onto a 3-cell Maglite eliminates the possibility to store the flashlight lens-down. But the product is not to be blaimed, that's just a by-product of installation. Light scatters a bit to the sides when using this lense, but the benefits of a sharper beam by far outweigh the occational ray of light in your face.

    Other: Just ordered two more!

  • decent aspheric lens for m@g

    posted by Flav_3 on 01:03:02 G9T 29/09/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Will fit m@gs as stated, just confirming it. If properly focused can give the led of choice very nice throw.

    Cons: Must keep in mind when considering this item that you're stuck with throw, no spill...unless you can easily change the distance between it and emitter. As with most items from here, shipping can take SOME time so prepare.

    Other: I would recommend this but shipping is a drag.

  • Asphericle lens upgrade

    posted by brianmolinaro on 17:55:20 G8T 12/08/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: 1.Made of glass 2.Very thick and heavy 3.Increases the throw of your flashlight 10 fold 4.Super easy to install 5. Extremely affordable

    Cons: 1. Fits a maglite well but is a little tight 2.The optics could be better 3. The lens sticks out past the bezel

    Other: This is lens is the perfect product that you can use to increase the throw of your maglite and along with an led upgrade you will have a super bright maglite that will be around 10 to 20 times brighter than it has ever been! With a price like this what are you waiting for you should buy one right now!!!

  • good heavy lens

    posted by electronicholas on 09:03:40 G6T 23/06/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: good asphericity, solid glass, heavy, at 3,5m I had my xml-t6 draw a 15cm square. Cheap enough if you only need a few.

    Cons: too bad the lens is not with anti-reflex coatings, but not that annoying, and also I do not expect to find a protection/defense crown for it any time soon

    Other: if you have 50mm reflector and want a thrower get this, it's good.

  • Not as good as I had hoped

    posted by DXjunkie on 14:42:20 G4T 28/04/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Only took 1 month to arrive April 2012. Cheap. Fits C & D Maglites. Measured focal length at about 30mm. Can be used in many different ways on other lights, not just Maglite. Works best WITHOUT a reflector. Held over an LED it works very very well. No bright ring. Good sharp focus of the LED die on wall.

    Cons: 1.) Produces bright ring of light in output beam on white wall at close and medium range with reflector in the Maglite. 2.) Not enough space in a Maglite head to get good focus. 3.) Needs 30mm between back face of aspheric lens and the LED. 4.) Despite un-threading the Mag head almost all the way it still seems a few mm short of good focus. 5.) Has the focal length of these 2012 aspheric's changed? 6.) Excellent potential with a non-Maglite flashlight!

    Other: Make sure your Maglite is putting out 500+ lumens for this to be impressive. May require a lot of adjusting and use of spacers to reach focus with the LED. About 30mm measured focal length.

    posted by 1Rupert1 on 10:44:24 G12T 18/12/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: This is probably the best and cheapest way to upgrade your Maglite, from the moment I received this product and I fitted it to my 2 cell Maglite and 6 cell Maglite I was 100% happy.

    Cons: It is not a perfect fit on the Maglite but once it's on it will not be going anywhere and at that cheap price who cares.

    Other: Buy it, use it, love it and also mod your Maglite with it!
    I did and never looked back since.

    posted by guitarzan379 on 16:57:12 G7T 25/07/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Direct replacement for D and C cell Maglites. I suggest an LED upgrade for it's optimum use. It's build VERY well - no scratches or any damage from shipping. I was quite impressed.

    Cons: All this did was refract the light on my maglight. Maybe I was expecting it to make miracles or something, but I didn't get anything but dismal results with my LED driver. Slightly undersized, but still mounts securely in the original placement of the plastic stock lens.

    Other: If you want to replace your plastic lens with a Glass lens, this is a decent option, but not the best if you're running an OEM mag LED driver.
