Hi all!
I decided to change the Cree on my Jetbeam Jet II IBS from a Q5 Cree that had a WG tint to my eyes and I don't like to a WC R2 Cree.
The mod went very well and fast, I took some pictures on how to do it and made me think about the level of Jetbeam engeneering that went into the light.
First you remove the batteries and head
This is what we are going to work with
Drill a small hole to the side of the led being careful not to damage the little wires
Then with a small screwdriver or other metal object pry the white centering cap off. we then get to see the module which is a 14 mm star, I noticed that Jetbeam does not use thermal epoxy to glue the star in place, they use some white thermal grease so it was very easy to get it out, just unsolder the wires and pry it out with a toothpick
Now here is my critique about jetbeam engineering,
WTF is that friggin hole in the center???? :shrug: I don't think there should be a hole in the center right where the emitter sits, also noticed that the metal base is very thin, no wonder it heats up on high :thumbsdow, this should be fixed :sick2:
Anyway, the stock cree is on the left and the R2 Cree is on the right, just happens to be sitting on a round star that is the same size and thickness :twothumbs, I proceed to clean the base and led up before assembly using alcohol and Q-tips
Red wire is the positive (+) White wire is the negative (-) I insert the new Cree, fits nicely! I used Diamond based thermal paste (IC Diamond) It's supposed to have better thermal properties than arctic silver, we will see.
I coat the underside of the new star and insert it to the base, don't worry about centering issues until you finish soldering the wires, Test the light before proceeding to put the centering cap back on.
then use the centering cap to center the led. Press firmly to make the paste spread and coat everything.
Here is a picture of the light, the top is the Jet II R2 WC now and below is a VB-16 USWO on high. I should have taken pictures before and after but was too eager to start moding sorry! But it does look a bit brighter than the stock Q5 cree and the tint is better to my eyes.
Thanks for reading!
