Very nice slopegatri70 !

But Djozz already mentioned the focusing, i have the same experience with the CSLNM1.TG in a C8. Centering is very difficult without the right gaskets, but it really makes the difference.
Not to mention getting the right focus, which means gently sanding down several gaskets until the correct height until you find the sweet spot

slopegatri70 · 2019-07-25T10:21:49.000Z

i figured it will require sanding down gasket, but there won’t be enough clearance left for soldering those 3 boards in series, if there was a way to reflow these on original 3x xml-2 mcpcb it would have allowed me to sand down gaskets. but i couldn’t find similar mcpcb.

btw, CSLNM1.TG can be used on xpl board, right ? because the 4pot lamp i have uses xpl leds and not xml-2 leds as i originally thought. so maybe i should order some bare CSLNM1.TG and reflow ?

does 3 vs 4 pot reflector dictates throw angle ?

Bad news, 2 out of 3 leds died within 4hrs of riding. i guess 16mm mcpcb wasn’t enough for proper heat transfer.

Hello,

I recently made a fixed thrower with a Convy L2 host.

Parts info:
CULNM1.TG 4040die (LED4Power.com)
LD-A4-20 driver 6A (LED4Power.com)
50mm plano apsheric AR coated (marinebeam.com)
Small RLT collar
Convoy L2 host
GOLISI S43 26650

Testing data:
Driver setting: 4.75A
Current measured at cap: 4.94A
Measuring device: Lutron LX-1108
Measuring distance: 5meters

*Without collar: 16700lux@5m@30s (417 Kcd)
With RLT collar: 31400lux@5m@30s (785 Kcd)*
_
Here is my issue:

While using this desmos calculator made by Enderman
Intensity calculator
My theoretical maximum should be 1700Kcd.

However, my result at 800Kcd is half of theoretical maximum! ]:<

Some side notes:

This is my first time ever using a RLT collar.
My collar location should be near optimal because I used 0.10mm shims until I got the highest reading. And also, it is almost double the reading without the collar.

I tried driving at 5.5A and the reading was only a bit higher
35200lux@5m@30s (880 Kcd)

I have only tried one CULNM1.TG. I have another, but I don’t want to change it unless it is highly likely my current emitter is defective.
_
Am I doing something wrong here? Getting half of theoretical max is no fun.

I am already really satisfied with how insane the beam looks. I can see the beam so clearly once it exits the lens.
I will be purchasing the Acebeam W30 because I can’t believe there is something out there with twice intensity as mine!

twisted_raven · 2019-08-06T02:10:28.000Z

Try measuring at 20m?

pscal · 2019-08-06T02:47:44.000Z

That is an awesome L2 build! Don’t fret about theoretical maximums you got from a calculator. 880 kcd from a 50mm lens is excellent performance!

We really need beamshots from your build

800kcd is unimaginable for such a small head with LED tech. How did you secure the 50mm aspheric to the head?

Are you sure you entered the numbers in the calculator right?
If I base the calculations on this test and use sample 1 as a reference, the calculator gives me 841 kcd. With sample 2 I get 914 kcd.

I enter:

290 cd/mm² (or 315 for sample 2)
- note: for a Lambertian emitter, 969 lm / 1.0609 mm² / π = 290 cd/mm²
50 mm lens diameter
correct the Wavien collar multiplier to what you actually got (from 1.19 to 0.88)
- note that 1.19 is based on an old test of XP-G2. Osrams respond worse to a collar. Enderman got .887 from CSLNM1.TG, so here you’re right on the spot.

So…your results are OK, it’s hard to tell whether you can improve on that.

You got a really nice light. :+1:

djozz · 2019-08-06T08:29:25.000Z

Your numbers are fine, it shows that your build is well-done . Indeed these Osrams do not give same multiplication of a collar that a XP-G2 gives (perhaps because of the shiny finish).

Agro · 2019-08-06T08:40:06.000Z

At low currents Enderman reached a multiplier of 1.07. So there’s some saturation going on at high current.
But at low it’s still less than 1.19. I don’t know the reason.

ADDED: at 5A the factor was 0.96 so a little better than likevvii’s.

Ohhhhhh!!
Thank you for the info!

I had put in an intensity of (500cd/mm²) because I assumed that the RLT collar would bring it up near there. Just to be sure I am doing it correctly; I need to set the intensity to ~280cd/mm²? Even though the RLT collar would increase it, I need to leave it alone and have the RLT collar multiplier take care of the multiplication?

After changing:
Intensity: 500cd/mm² to 280cd/mm²
RLT collar multiplier: 1.19 to 0.88

I get: 904Kcd! This is much closer to my recorded data.
Could you verify if my settings are changed correctly?

Agro · 2019-08-06T08:45:22.000Z

Hmm…with 280 cd/mm² I get 812 kcd.
From the defaults, I changed only the 3 fields that I mentioned above.

I see, I had been playing around with that calculator for over a period of weeks. I messed around with all kinds of values. I just realized I had changed the: Lens clear aperture CA (%) from 0.90 to 0.95 because I had an AR coating. My values match yours now.

Thank you again

likevvii · 2019-09-14T11:02:13.000Z

For those who messaged me about mounting the lens, I have the link to the album below. I used 3D printed parts to seat the lens perfectly focused. After screwing on the head, the lens would be very secured and unable to move. I was able to adjust the RLT collar easily because the lens comes off very easily. However, it took about 14 iterations of 3D prints before I got the right fitment and focus.

L2 build and beamshot pictures

I really want to reach 1Mcd with the convoy L2 host. The best thing about the L2 is that it is very compact and the cooling is great because the entire head is the pill. The convoy L2 allows for a max ~58mm diameter lens. I am in the process of talking to multiple suppliers in China to produce a precision grounded thin double aspherical lens so the convex bulge wouldn’t stick out of the L2 head.

Agro · 2019-08-06T09:21:11.000Z

The calculator takes AR coating into account under “Glass transmission”. The default is a coated lens.

Custom lens….that’s expensive stuff. Maybe getting a stock 60 mm one and grinding the sides would be a better idea? Or opening the head a little more?

djozz · 2019-08-06T09:32:09.000Z

Good luck with getting your L2 even better!

Yokiamy · 2019-08-06T09:56:16.000Z

Wow, thanks for the album, impressive!
Really need to find someone with a 3d printer or lathe
