KR4 Basic review

Edit: XPL HI, 5000K. 18350 tube SS bezel, 30Q.

Just a very basic review and some comparison shots no one asked for :slight_smile: I will leave the detailed reviews to the experts here. So basically just my impressions so far. The “gray” is a bit blue to my eyes, I like it better than just plain gray. Fit and finish is great and I think the stainless bezel really makes the light pop in appearance. I also really like having the SS bezel since the anodizing won’t get beat up and another bezel can be ordered if this one suffers a mishap. I should have thought about that sooner…damn… I didn’t get the tritium since I was unsure what color I wanted. Probably classic green, I think that will go well with the gray.

All my run time so far is with the Samsung Q30 Hank includes. My Lii-500 got lost somewhere in “awaiting despatch”, so thankfully I had a Folomov A1 from a combo deal for the EX11.2 on eBay.

I was not all that impressed with Turbo, but I will see what happens tomorrow night when my 25R and LG HG2 cells come in the mail since those support more current than the Q30. Not a lot, but more can’t hurt if the light needs it. I did expect a more significant step in output, but it might be my eyes, or maybe I need more space? I can feel it get immediately hot compared to full ramp which warms slowly. The optics are fairly floody, with no apparent hot spots when used outside. I have the temp set at 60. It does get painful in what seemed like 10 seconds. I may find time tomorrow to set up my Lab-Jack and datalog the temp rise. It definitely seems like there is a good amount of heat conduction to the outside, since I feel the temp rise almost immediately. That’s a good thing. If it was slow to heat up it means the heat conductivity is poor.

I will also be getting a Keeppower 18350 so I will get some shots of that tomorrow night as well. Not sure how useful 750mAH will be in this light but I suppose enough for one day light use.

Now for the pics! These were done with my Pixel2 which takes good shots but for the beam shots I had no ISO control or anything like that. I thought I used to have more control over the camera but now I see the only real option is turning HDR on or off. What the hell?!

Sour Patch Kid for scale.

He didn’t make it through the 18350 swap.

Yard before. I need to get something to block the police station view.

KR4 Full ramp

KR4 turbo with the Q30.

Sad D10 R2. Time for an emitter swap. And controller. Alkaline cells seem to leak more often nowadays.

Alkaline damage. I have to machine the piston and nickel plate it again.

Extreme E3 is the thrower of my collection.

That TIP though….

EX11.2 - hard to not be my favorite.
