Any K2-TFFC LED drop-ins?

Title says it all - specifically P60 sized drop-ins would be of interest. I know there are loads of Cree drop-ins to choose from, a couple of SSC P4 based ones...

Cheers!

Now that would be sweet.

Gene Malkoff, you listening?

I thought the K2 was kinda inefficient? I'm missing something here maybe?

The tint. The beautiful tint.

Then TFFC(Flip Chip) K2 is much more efficient, though still not as efficient as the better Crees and Seouls.

Luxeons seem to have better color and resistance to heat then the other LEDs though.

I have not seen any K2 TFFC drop-ins. Though there was at least one K2 drop-in.

Ah, so this is for a Nitrolon G2 then? It would still need a kick-down heat management feature then I'd assume. It would just go longer before the output dropped from heat?

To bad the old K2s were junk! And now the new K2 is hard to find, but I am glad to have on installed in my Gladius.

This was really an easy swap. The reflector I don't really care for, it creates a little donut in the middle. Plus a light that is so well put together and the they use a $5 reflector!?! I plan to replace that with an McR27L.

Here's some photos. I can do some beamshots if anyone wants them.

What everyone says about the color tint of the K2 and Rebels is true. They are excellent, to bad availability is low.

Not really, is that the Luxeons seem to be able to take more punishment then most other high power LEDs. It's still not recommended to overheat them.

I think many companies prefer the higher output of the Cree and Seoul to the better color of the TFFC K2.

i plan to make my own K2 TFFC drop in.
i have 1 K2T left,just finding the right reflector.
i have one with Rebel 080 and to my surprise the tint and the focal point in this drop in is so nice & warm,have been running it with 1x18650 no heat issue at all
picture soon

please pardon my soldering skills due to bad soldering iron,haven't decided which new iron should i buy.

the drop in rb80 (emitter from DX) the driver have 5 modes





RB80


fenix p2d rb100


inova T1 2008 K2 TFFC


my pimp L1 Cree with 1.2A

ive actually becomes used to LEDs that everything else looks ugly greenish....still..bring on the K2 dropins!

Crenshaw

finish my swapping in my sku 4068 to K2 TFFC TWOF emitter and the results with UCL was WOW !

with UCL lens close up check out that blue hue on the lens :devil: really nice

now for the beamshots comparison the K2 TFFC TWOF always on the right
vs Kai's K2 $2.79 emitter

vs Inova T1 2008 K2

vs Fenix P2D RB100

another shot without the reflector

overall output - I'm pleased with it due to warm tint.
I just can't wait for the new Luxeon K2 TFFC Cool-white Emitters -- 250 lumens at 1A, 300 lumens at 1.5 A -- Tj of only 5.5 °C/W, part number: LXK2-PWC4-0250 or higher :devil:

WOW!!! That TFFC tint is nucking futs!!!:bow: I gotta get my hands on a light with those
