I’ve had in my possession for maybe a couple of months this big KD reflector and I’ve been on the lookout for a suitable yet not to pricey host. I just couldn’t seem to find a budget enough host so I ended up trying to ‘fit’ this reflector with a tk61. I like the tk61 not just for it’s performance but also for the general feel of it. It’s not weighty, the 2s2p battery set up means you can run high capacity cells and not worry about high drain, and it has a side switch. On larger lights like this I really prefer the side switch option. That’s part of the reason I don’t have a K40, (sold my…) K50, TN31 etc…
Anyhoo as you can see the reflector is not an easy fit and I had to ask for help to make it fit. A friend helped me out there. The host I used is a TK61vn PDT, so it’s had a current bump and dedomed led. Unfortunately I damaged the led whilst screwing around with this reflector so the new led is a dedomed xml2 u2 2c.
While me mate had the light to make the extension ring I ordered 2 more reflectors. KD’s site said they were out of stock of the 85mm x 86mm reflector but had stock of 86mm x 90mm reflector. So I ordered the larger reflector and hoped I’d be able to squeeze the extra 5mm if I ever needed to replace the one with the light. As it turns out what they delivered me was exactly the same reflector (85mm x 86mm) so I had 2 direct replacements for the light :party:
The initial reflector I had was not overly shiny and me mate told me there was a 6% drop in OTF lumens once he had fitted it all together. The second lot reflectors I got seemed to have a better finish, not as good as the fenix reflector but better than the initial reflector. Below is the initial reflector, second reflector and original fenix reflector.
So me mate did a great job on the extension ring. One of the reflectors fit snugly into the ext. ring. Later I found out this helped greatly to find the best focus, as I could unscrew the ring to move the reflector away from the led yet still keep it centred.
When the light came back to me it still had a domed led. I didn’t particularly like the beam so I got out the thinners. I cheated a little, I unscrewed the head and rested the light upside down on a cap/lid filled with thinners. Saved me from removing and reflowing the led :davie:
So here’s a wall shot (no it’s not a white wall is it) of a stock tk61 vs KD reflector tk61vn. I can’t remember the distance exactly, I think it was about 5.? metres
Not really indicative is it. Here are some better shots.

As mentioned earlier I played with the focus a bit. The following shots are of moving the reflector away from the led. The tight spot with large ring is reflector hard up to the star, mid is about 1/2mm away from star and the last more than 1mm is a large hotspot with no ring but less lux . I think the mid point is my preference at this stage.
That’s about it until I get out for the all important outdoor shots. I want to make comparisons to 1 or 2 of my other lights as well. Oh, and dedome the stock tk61. I’ll try to get time within the next week…maybe…
