The Monster TK61

This guy must be crazy! :slight_smile:

Can’t wait to see the monster alive!

Its the water out West that makes them different. :wink:

No idea what you’re talking about ???

The openings on the khatod optic are indeed very small. I wonder if a lot more light is lost (not collected by the optic) when the larger XPL HI is used.

It sounds as though I might be safer just using the Carclo optics. I don’t want to have problems with the emitters in this light. They cost a small fortune!

Can’t wait to see how this monster comes to life, please hurry with the build :slight_smile: .

So it’s been about 2.5 years since I started this thread and I haven’t been very active around here for a while! Life has taken priority with buying a house, getting married and going on a long trip to the US for our honeymoon.

However, I decided to pull my finger out and get this build going again. The sad part is though, by today’s standards this light isn’t going to be overly impressive anymore! :cry:

Anyway here is today’s update:

I modeled the heatsink/spacer in Rhino

I then took the CAD file and my chunk of aluminium to the machine shop and this is the result:

A few more things which have happened:

- I’ve decided to purchase two BLF GT 4S battery carriers from Neal rather than modifying the factory ones as I think I will end up with a better result this way, it will be cleaner and should carry more current.

  • I have purchased some more 16AWG Teflon wire and think I will go with blue and transparent now

That’s it for now and hopefully the next post won’t take another 2.5 years!

Nice job! :+1:

Not impressive Your build is a great idea! :+1: :+1: :+1:
If possible, make sure your heat sink makes good contact with the host to exchange heat. Im looking forward to seeing how this progresses.

If the idea is to outdo everyone around the world then maybe it won’t meet the goal, but if the idea is to have a very powerful floody light for your use then you will definitely succed in that! Should be easily 25,000-30,000 lumens with some sustainability to make it quite useful, I think you’ll be very pleased with the end result and find you don’t even need to run it in Turbo to still have an outrageous advantage on things that go bump in the night.

Sweet work they did on that heat sink. I join the ranks of those looking forward to see it wired up and working. :smiley:

I’ll take one thanks. :open_mouth:

Welcome back from reality. :slight_smile:

Like the pyramid scheme with the leds. Subscribed.

Gonna sell these ?

It might not have the wow factor it had when you started but it’s still a wow light, and a highly custom one off at that.

Good to see you continue with it :slight_smile:

Thanks for all the comments everyone, I’m going to try and get it all wired up over the next week and hopefully in the meantime the new battery carriers will arrive and I can do a couple of things with them.

I’ve had the heatsink machined so it is a slip fit into the top section of the head of the light. I’m not sure if you’re familiar with inside a TK61, but they have an aluminium tray where the original MCPCB sits and that tray is screwed down on to a raw aluminium shelf in the neck of the light. My heatsink sits on this tray so I will have some AS5 beteween the tray and the shelf in the neck of the light and then some more AS5 between the heatsink and the tray and it will be all screwed together - tray to light, heatsink to tray, MCPCBs to heatsink to ensure good contact. Fingers crossed it’s enough!

Nope! Way to much time and effort required for someone that just does this as a hobby.

I had to buy a TK61 because of you! :stuck_out_tongue:

haha! I love it!

They have a great form factor in my opinion. I have a second one with a 4P converted battery carrier, FET+1 and a dedomed XM-L2 and so it was only natural to make the second one into a flooder.

What plans have you got for yours?

Not sure yet, I picked up a Vinh modified one so until I receive it later in the week I won’t know just what I think about it .

That said, it has occurred to me to use a boost driver and run an XHP-35 HD for a spot light effect with pretty high lumens. (2600 or so)

Have also thought to just put an SST-40 in it and run with it. Already have a couple of throwers I built from scratch so I have leeway to not worry about max throw and focus on beam quality.

I also have a 4S carrier for the TK61 as well as a custom driver that is not quite complete… torn between readily available options…

AND I recently modified a 61 for a friend using a White Flat that yielded 835Kcd… so I really just have to get the light in hand and get a feel for where it wants to go. :wink:

Once I get this CNC in my shop functioning I plan on doing some goodies like this, right now everything is old school manual which does keep my skills sharp.
