I bought this last week from the marketplace and didn't care for the tint, so I decided to upgrade it with a P7.:grin2: It's a bit brighter now. There is a slight + in the center, but is not very noticable in actual use. Overall, I am very happy with the finished mod.


- CSXOI P7 Emitter
- Stock KL4 Driver
- Enlarged Reflector Opening
- Modified Heatsink

Just to add...updated 2-2-09

IMO, the P7 works MUCH better with the KL4 reflector.
I have done about 3-4 MC-E-KL4 mods and 9-10 P7-KL4 mods and this has always been my experiance

Wow - You make it look easy. Now I just need to find a shop to enlarge my reflector opening.

Good stuff!
 
Re: P7-KL4

Great job again! You're really cranking out those SF mod, I've been watching them all. Going to have to start calling you the SF master!
 
Re: P7-KL4

Thanks for the compliments!:D

Well darkness has finally arrived and my first impressions are.... WOW!!

I don't have a stock KL4 to campare it to, but it lights up my backyard quite nicely:twothumbs:naughty:

EDIT: I have a stock KL4 now

I'll try to get some good beamshots up tonight.

The KL4 just looks so evil with that huge LED in there:laughing::thumbsup:

I think I'll refer to this one as the "Hot Rod" .....Big engine in a little host with the throttle floored:crackup::cool::kiss:

Is is still a 2xCR123A light, or do you power it with a single 17670? What's the drive current?
 
Re: P7-KL4

It is the stock driver with 2X123's




Got a new camera....

Re: P7-KL4

Curious, doesn't the stock driver put out 6v? The P7 can handle it?

The baby is bright! :twothumbs



I have no clue what the stock KL4 driver puts out:shrug:

It IS bright as hell!
I've been using it constantly since doing the mod with zero problems....it gets warm, but I also don't run it for more than a few minutes at a time.

Honestly, This is now one of my favorite lights.:twothumbs

The stock KL4 is a complete jock when compared to it....now I just wish I could get my black one open to do the same.:cool:

The KL4 has a boost driver which drives the LuxV with its 6+V Vf at ~800mA. With 2xCR123A and P7, it probably goes direct drive...

An MC-E in 2s2p configuration would probably be a better match for this driver... but who knows whether or not it it would work well with this reflector.
 
I'd love to know if it gets as hot as a stock KL4 can when used for long periods...
 
most likely thats a yes...which is the primary reason why I'm hesitant to go into P7s...the KL4 head is already poorly suited for a luxV in terms of heatsinking.....I dunno what the P7 could do to it.

Its an interest comparison too..both KL4 and P7-KL4 are 4 die lights :twothumbs:
 
KL4 can actually host a 6 die 1000 lumen Ostar, underdriven a bit.

KL4 heads are fun to open up, eh? :)
