I think this is my first post, so I guess I'll make it okay- I have a Coast Lenser T7 (P7 stepbrother) that I've been tinkering with. One thing that I have noticed about the lenser products that I've owned is that there's a loss of light on the backend (behind the lens) since there's nothing but a heatsink and ....black seals -_-. So here is my fix that is virtually cost free! Also, I hope I'm posting this in the correct location.
Below is a shot of me disassembling the head- it's pretty straight foward as long as you have needle-nose tweezers or in my case, surgical scissors.
I know some lurkers won't be familiar with the innards of a Lenser, so here it is all layed out.
Here's a shot of THE LENS.... also the base of what I'm working with/on.
Okay now here comes the crafty part! I used aluminum foil. There are two sides to foil.... one's much more reflective than the other, and this is key- wrap this around the now disassembled lens, make a pseudo cut, and place lens in safe place while we continue to work with the foil. Here's my roughly cut foil.
Obviously it's going to crinkle up too aggressively while you're manipulating it, so after the cuts I used the head of the torch to "roller-pin" the kinks out.... as so....
Here's one more picture to show the difference after the rolling- notice it reflecting.... this is the desired effect.
Go ahead and touch ends and you should have the cone below! use the lens for assistance to get this desired shape.
Go ahead and put the cone on the lens and reassemble the head... we're done with that part now. It should look like this.
This part is kind of key, and I missed it over and over until it finally hit me when I zoomed in and noticed the LENSER sticker around the LED mounting post... this post is a huge reflective hotspot, so we gotta wrap it up too. Don't worry about heat dissipation, aluminum will just help to disperse the heat away from the core. Keep in mind, reflective side is out away from the center.
Okay now let's see how everything fits together....
Same shot with it on...
1m white wall (Spot).... note the new spill
1m white wall (Flood)... not too different, also realize that this pushes the LED post up into the lens which bypasses the post reflector and most of the newly added reflection.
It's raining out, so I just got some shots in a blacked bathroom of mine. I'll throw up some outside shots later if anyone wants/cares.
3m (Spot)
3m (Low/Survival)
3m (Flood)
The light is SIGNIFICANTLY more efficient with the extra spill and it's noticeably more refined in throw. Keep in mind these were ALL taken with my cellphone, so I'm sorry if some of the quality isn't up to par, but I don't think they look too bad. I'd also like to make one more special note- foil can actually be polished with chocolate, and I wanted to try it, but I can't find a plain chocolate bar, so if anyone tries that, I'd like to see it. Also, I've owned multiple Lensers in the past, and they all contain this similar design- if anyone tries this on any other one I'd love to see results. Thanks for checking this out, and cool forum.
