No , haven’t tried a bearing race . Maybe after I finish this one , I’ll look into that . Thanks for the idea . I have been recycling / repurposing materials when I can figure a use for them.
I sliced two more LEDs today and made a quick video since a few pages back some questions came up how to do it.
My post with video link and a few extra details not described in the video: Video showing how to slice the dome off an LED with washers

Very neat, a nice karambit :+1:

That gave me a good laugh. It’s not really a very practical type knife .
I think maukka, TK, probably bob all have something similar but I decided my mobile modding station needed a bit of light and I just couldn’t fathom working on high CRI flashlights and having a low CRI desk light.
The arm is huge, probably overkill for this size desk but if i want a really floody option I can get it real high up or use it on the opposite end of the desk, so i’ll keep the bigger swing arm. Pretty popular and affordable ~95CRI Viltrox L116T light with a (optional) DC adapter.

Bonus tip:
You can see my ridiculous haul of optics from Yajiamei. Add a bunch of shit to your cart and do the classic “order but dont pay” then send a message to them to adjust the shipping costs. Thank me later.
Nothing special this time. Luxeon V 4000k, TA with bistro HD FET+6+1. All this in the L2T body with the L2P tail. Led soldered directly to the KD pill. Pill surrounded by copper sheet and tight pressed into a flashlight. I still have to make the switch and it will be over.
Thank you. It looks like I’ve always overpaid.
How much did you save?
Yep, I can confirm we’re all using the Viltrox as a work light 
I upgraded mine to the architect lamp style arm instead of a flex arm earlier this year and I’m much happier. Zak and I have panels installed on the arm that comes with the Ikea Tertial lamp because it’s cheap and very robust compared to a lot of ones sold separately on Amazon.
Product Amount US $ 8.17
Shipping Cost US $ 28.95
Tax US $ 1.66
Total US $ 22.53
This was about 30 optics with about 24 unique types so it had an absurd $29 in shipping. I guess they marked the shipping down by more than half?
Did you fix the centering ring on this…
I also have the Ikea Tertial, but I use it for one of Bocian’s 4000K LED bulbs. Viltroxes are all on flexible goosenecks with spring clamps, so I can easily move them around for different purposes.
Clearly you missed the word “professional” on the box of mine…
I saw the Ikea lamp option in my shopping around for ideas but the Ikea in my (big) city is quite a ways away and it’s a mad house inside.
Sorry. I do not understand what you mean.
I used the butterfly pad for xm size leds.
2 corners of the LED are inside and it looks like the opposite corners are under the ring…enlarge/blow up the pic…
I see that too, might be better to just round out the inside so it can spin freely
The corners are probably crushed when tightening the reflector. I had something similar in Convoy M1, also with luxeon v.
I didn’t mod a flashlight but I did change the oil on the truck today. Couldn’t find my filter wrench. Drilled a hole through the filter, put a screwdriver through the hole and loosened it that way.

Hadn’t built a light in a while (weird huh?) so I put together a 17mm FET+1 and assembled an X6 from host stage with a 20mm Noctigon and Samsung LH351D W6 5000K emitter. Bypassed the spring in the tail and used a large Blue spring on the driver. Straightforward enough, right? Done this dozens and dozens of times… this time the driver blinked down to moon at level 4 of 7!
So I did the mod using two 2000 resistors and got it stable, makes 1460 lumens with a GA cell. Now the typically easy reversing doesn’t work properly. Won’t work at all in the default mode and the medium press mode takes almost 4 seconds to shift it down. Have forgotten why this would be. Getting old…
