K2s aren't exactly the most efficient thing on the market... they have to compete in price to leds almost 3 times a efficient and only a couple more dollars.

Scott_T · Feb 15, 2008

Well I got one anyways, cause you know... they're neat looking and I'm a flashaholic. I'll stick it in something.

neat looking? you can get an scc for less than $5 and a cree for a little more and you get 3x the output for the same amount of power. but hey, it only $2.79... therefore, buy both!

i have 2 of those and the beam is awful rose tint.

jufam44 · Feb 15, 2008

Ordered 2-hopefully we'll see how well they work!

They can reach a high lumen output with low heat generation according to the marketing. I bought one recently, the tint is definitely the best of any LED I've seen (warm white, not "rose"). I put it in one of these and although the tint is a lot better, the original LED was a bit brighter.
I think these are good for applications where heatsinking is inadequate (because they're so cheap) or they're driven from mains power.

Scott_T · Feb 16, 2008

Sirlightalot had me confused saying how the cree has 3x the output for the same power and I finally realized he was confused with the old luxeon jobs that ran at a million degrees. These are the new ones that came after the rebels. 3 watts and 100 lumens. Its not too shabby, especially for $3.

jzmtl · Feb 16, 2008

I don't think those ones on kai are new version. they don't say it is, plus they say it's 100 lumen. Old version is 130 Lumens typical at 1500mA so this one sounds like in the ballpark.

Scott_T · Feb 16, 2008

With the hex shaped head it sure looks like the new one

Bought some, attracted by the price.
Large variation in tint.
They run much hotter than DX crees (normal p4), while giving less light.
Not really worth it considering how cheap we can get proper Crees.

It does look the same I am not disappointed the price was right!

Mash · Mar 28, 2008

how many did u get? how do you find the tint, and the running temps?

Crenshaw · Mar 28, 2008

someone fire these up and tell us if its the new version?

almost too good to be true!

PS: wow thats gotta be TORCH_BOY's longest post in awhile...

These are the old power hungry K2s. They are no better then the old U bin Luxeon, in fact, I would rather use an old Lux 3 than one of these.

The new k2s will kill these in output and tint.

This is the new k2. Notice the rebel grid.:devil:

Mash · Mar 28, 2008

mine have the same pink/purple tint!
I guess its their idea of "warm white"!

Crenshaw · Mar 29, 2008

is it just me or does the Kai one look warmer?!

:thinking:

Crenshaw

nanotech17 · Mar 29, 2008

actually the camera is having a hard time catching up the warm tint.
in real life it is really nice warm tint.
