What did you mod today?

Under 12” it’s a solid beam (and looks cool as hell), over that distance and the donut hole is ever expanding.

Its sort of a proof of concept / test bed for a ZY-T08 mod I’m working on with XP-L HI and 4 red XB-D’S.

I’m confused grin, you say 145mm aspheric but the photo shows the lens not much larger than your K75, am I missing something or forgetting how big the K75 is?

Fun stuff isn’t it? :smiley:

Lux times distance squared, probably need a 20M or 50M lux test to really get a good read on it. That would be candela, multiply that by 4, then take the square root of the answer for throw.

So, like on my last 5M reading (25 multiplier as 5x5=25) I got 45200 on the meter, for 1.13Mcd. X 4 = 4520000. The square root of 4,520,000 is 2126 so that light throws 2126M or 2.126km

(CFT-90 in a 95mm reflector driven at 22.4A from an FET driver off an 32650 at around 4600 lumens. I’ve since had it show 5010 lumens from a Samsung 30T but didn’t retest lux)

Haha I was in denial when i first came here.

The k75 is a big light here it is with the lens out of the housing has a few scratches. But now i have the dimensions i plan on buying some big billets of aluminium and a new lens so i can get it looking better.

Thanks for bit a clearer explaniation I will eventually get it right. My disto showed a service message when tried to measure the distance more accurately. Might be cheaper to buy a new one. So i will have to wait.

I have a 178mm lens for the next one which will be shoulder held that is what I want the cft-90 for, it will go well with the 8x6w laser diodes i have for it. already spent over 2k on parts for it.

Wow that is certainly some dedication. I think if people want beam shots they can just tell you a latitude/longitude and you just shine it that way

I have a 200 mm Edmunds that shows 2.4Mcd in open testing, probably won’t build it though. My 10x22 lathe doesn’t like that huge bar stock.

I’m liking the ice blue LEDs. I have some on order from eBay to put in a lighted switch.

Arh i just looked them up 200mm is $100 cheaper than i paid for the 178mm. Only problem with that is 200mm will need a bigger billet unless i do a lost wax casting to use the pile of swarf i have.

thinking of using thermoelectric cooling or endermans method of liquid cooling will make it easier to mount the focus drive motor. The liquid tubes can run from the back of the light through a carry handle into the black driving light housing where a copper coil will be. Cctv camera with PTZ module to act as range finder and control focus drive motor and will allow for remote operation.
Here is a bit of a layout of the host.

Battery pack will be 4-5s4p 21700 samsung 40t

Used my new Oveready Bezel tools to break open the blue locktite on the V11r control ring assembly.

Added more Nyogel 767a, to slow down the control ring. Nice result, still works with one finger, but wont move unintentionally.

Still Loving the 3500k E21a, it is quite beautiful, and makes red POP more than my 219b’s,

and works well both at night and during the day, without being “too” warm

If I could have only one… (not gonna happen), the E21a 3500k would be my pick for an all purpose EDC. (My sw45k are feeling neglected.)

I will do an E21a 4500k next, to compare with the sw45k that has been my main squeeze for the last 6 months… (with a few dalliances along the way)

I modded the rebar chairs on left into water pump cage on the right .

Reckon I’d be grinning too with such grandiose plans… subscribed. :smiley:

Modified an Original RRT-01

installed shaved LH351d, thanks to moderator007 and installed Kaidomain reflector, also thanks to moderator007

added Nyogel 767a to smooth out the ring control

the LH351d is 34% brighter (545 lumens on IMR 18350), than the sw45k (408 lumens on IMR 18350)…
LH351d is greener due to the Slider Effect (I compare everything to N219b sw45k…) lol

Nice, if you want warm I can shave a 3500K for you (also you should try to source a plain lens maybe from esslinger.com)

very kind of you to offer… will think on it

next:

Mod Original RRT-01

LED to 219b 4500k sw45k
reflector to kaidomain
control ring to Nyogel 767a

proof of light

the reason the beam is not not pink, is the photo is taken late at night under incandescent, so the sw45k looks cool blue… the Pink will be back tomorrow, when the sun is shining again

Yesterday I modified one of my Nitenumen NE01 to be able to use it in cave excursions (in Rome there are several caves under the surface)

I replaced the parabola with a 120° TIR, then I added some rubber, against small bumps, obtained from an old and too cheap binoculars. In the excursions the strap will disappear

Nice looking modding job jon_slider :+1: .
I really like your comparison pics also, way better than I can do.
Now you got to try the sliced 3500k contactcr offered or a sliced 4000k that I’ll offer to send your way.
.
@contactcr
You wouldn’t happen to have a comparison shot of the sliced 3500k would you. I might like to try one myself.

Don’t have a beam shot right now but here’s some measurements I took a while ago:

S2+ light op reflector, 5.5A linear driver, low to high:

CCT = 3215K (Duv –0.0001)
CCT = 3247K (Duv –0.0002)
CCT = 3288K (Duv –0.0007)
CCT = 3332K (Duv –0.0030)

Below BBL with reflector is about as good as you can expect of any LED these days

Alright, you talked me into it. PM inbound.

really appreciate your contributions!
Im not quite ready for the brighter LH351d… it works great and hugs the BBL well, but atm my GreenSliderSyndrome is getting the best of me… lol… maybe its because of my cataracts that Im so in love with my pink tinted LEDs…
My favorite 3500k LED atm is the E21a in my V11r… need to order a few more from Clemence to continue my testing… there is a lot of room for improvement in the beam Im getting…

This is the beam in a V11r w stock reflector… I can live with it (because I focus on the hotspot mostly), but its not ideal

This is a beam I consider excellent, from a 219b

when using the reflector and centering ring that works for the 219b in an RRT-01 the beam of the E21a is unacceptable (led sits too far below the bottom of the reflector)
