Led4power.com : LD-4 CC linear drivers, ILC-0/1 illuminated tailcaps, optics, MOSX, copper DTP MCPCBs...

Complex little driver! I just put a 6A LD-A4 in an Eagle Eye X6 host that came in today. I soldered two 20mm copper boards together for height, used a 35mm TIR with a deep narrow “cup” over an XP-L HI and connected these with 20 Ga Turnigy leads. Set up for 5A, with 4 levels and moon mode engaged it works pretty nicely.

The large TIR will show it as unique, the LD-A4 guarantee’s it. :wink:

Where did you buy the TIR for X6? can you give the link please? Thanks Dale.

I honestly have no idea. It was in my kit, appears to be new, was in the black plastic holder and I had to remove it to fit into the bezel of the X6 which was a little tricky. Works pretty neat…

Was it from Justin?

I have bins and bins of bits from Justin, as much or more than what I already had of my own. His stuff and my stuff together makes for a LOT of stuff! I can’t remember my own purchases, still finding things in his stuff that I didn’t know I had.

Y’all just can’t know, it’s like he’s here with me all the time. :frowning:

Bittersweet, at times. Uplifting in other moments. And so it goes…

Hahaahaaa thanks anyway Dale. Wonder if it’s one of the Kathod optics or not…

Straight, no spacer?

Its taken me awhile to remember where I used a similar optic. Justin sent me the optic. Cant remember the diameter but thought you may have used one in your mod.

I think that optic might be Ledil Iris, if it’s ~38mm. Doesn’t look like Khatod PL1672.

Edit: measured actual Ledil Iris optic at 35.0mm. 38mm includes the holder diameter.

I received the KW CSLNM1.TG leds today. I will do an output test one of these days (if maukka or Koef3 do not beat me to that :slight_smile: ), but for now I measured tint at 0 degrees, 30 degrees, 60 degrees.

0 degrees: 6100K on top of BBL, CRI 68
30degrees: 5800K creeping up above BBL, CRI 67
60degrees: 5300K going further up, CRI 65


WAIT! Dots? Are these some kinda micro-COB emitters or something? Won’t those tiny dark spots make it challenging to get max luminance in a thrower?

Same as the black flat, not any significant variation when on high power.

Completely invisible after all the imperfections on optics.

Thanks Enderman!

You’re welcome :slight_smile:

The “white flat” looks so pretty :slight_smile:

Thanks Hoop, nice info.

Can’t wait to get mines !

I forgot to put my old test results:

I calculated/estimated lumens from my lux numbers and datasheet bin specification.

Yellow marked lumens calculation are based on old black flat measurements at 1A as reference (made by koef3 I think), non-marked lumens are based on ~middle of bin lumen number at 1A from datasheet (330lm, actual middle is 335lm).

Using yellow for calculations….
If this emitter really has 1.0609 mm² and 952 lm we’re at 285 cd/mm².
Note that according to package drawing in the datasheet this LED is 1.0609 mm² minus rounded corners.
Also note that the Blackie HWQP while nominally 1.0609 mm² minus cut corner was measured at 1.12 mm².
I tried to measure the size based on djozz photo, but haven’t really arrived at satisfactory numbers…

Assuming that it actually is 1.0609 mm² it is much more efficient than the previous generation (in terms on intensity vs. efficacy). I’m really anxious to see a Koef3 test where I can compare it with the competitors directly…

That’s what I’m seeing, note that I’m far from fully trusting the chart.

Interesting point:
I still think there’s something that we don’t understand about Synios. If we add it to the chart with intensity that can be calculated for a Lambertian 0.503 mm² emitter, it looks like this:

Likely coincidence though.

My son and and a friend who was coming to play at our place had way too much energy so I kicked them onto the streets to play in the playground a few streets away. So that freed some time for the led test.

Note that I used my standard test method with all the added disclaimers about how it is done. Especially note that I keep using the djozz-lumen although I know that it is between 7% and 10% too high, I do this to be consistent, so results can be compared to all my earlier led tests.

I used a DTP 16mm led4power board for reflow because those pads matched the smaller Oslon pads of the led just a bit better than a Noctigon. And indeed the reflow went easy.

As I noticed before my maximum is at a lower current than other testers, the cooling seems less well done in my set-up. Part of it may be that I usually apply a generous amount of solder during the reflow, a bit more than the minimum needed (with Oslon-sized leds on 3535 boards, excess solder can not be squeezed out by tapping on the led). This results in a somewhat (not much though) thicker solder layer that may add to a slightly higher thermal insulation of the led.

I stopped the test at 7A. The led emitted angry blue light then, but I kept it 2 minutes at 7A to see if it could handle it, and it did. Afterwards I turned the current down to 4A and kept it there for half an hour, the output was only 1% less than the initially measured output at 4A, so the led seemed to have handled the 7A maltreatment with no problem.
