What did you mod today?

I liked the dedomed 3000K 519a so much, I did another one:

I removed a 3000K 219b and went w 519a because of lower duv and higher output, over 650 lumens momentary maximum. Or, longer runtime at lower outputs (efficiency).

the glow tape I bought is just too much fun… makes me giggle… LOL

the punches are a 13mm and 6mm from aliex

Nice mod jon_slider. :+1:

Agreed, the dedomed 3000K 519A is very nice, but the 3000K 219B is no slouch either.

Thank you! :wink:

fwiw, I removed this 3000K 219b

because the duv was above the BBL.

I like the lower duv of the dedomed 3000K 519a. It is also about 50% brighter (or more efficient at similar output)…

Yikes, that’s not a good 219B! :cry:

My sw30s are a little rosy, but they’re also in a triple with a green AR lens.

totally agree! it went in the trash

here is a 3000K 219b with Tint Duv that I like Much better:

Ahhh, much better!!!

Maybe I should have been repurposing all those ugly brown emitters to people who like them instead of throwing them in the trash. Anything under 4750 or so is an immediate bin filler around here.

Also very happy to be blind to the line. :wink:

You’re blind now too Dale? Dang. That’s rough.

What was it this time? Magnesium in the chop saw? :sweat_smile:

Tested an old TA driver with an SFH-55 on the bench. Puppy is intense!

I machined the emitter shelf on a Mezzol X6 for the 24mm board the SFH-55 came on.

Machined the brass driver retaining ring to clear the ring of 7135 chips on this multi channel driver.

Then I opened the new X6 reflector to 9.54mm to clear the 16 dies of this huge emitter.

Used 18 ga leads from the driver and a 20 ga spring bypass on the switch spring.

With a freshly charged 25S 18650 it showed me 4 modes, highest being 610 lumens. Huh. From Moon I backed into Turbo… BAM! 31.3 Amps for 7820 lumens!

Did I mention this emitter is intense?

Nice Machiny !

I need to ask TA what might be wrong with this driver. Seems to be a channel skipping out in the middle or something.

It has an SIR404 MOSFET, Raptor claw 7135’s all around. It was in my kit so I must’ve got frustrated with it and moved on back when i originally built it.

Playing around with this SFH55 X6, I discovered that there are modes behind Turbo, battery check, bicycle, etc…but it’s a very brief press and hold to reverse into these. This is a pretty normal set for Texas Ace Bistro, but the 4 forward modes with 610 lumens as the highest is strange. No blank spaces, cycles repeatedly through 4 in forward action.

Moon…

There’s a threshold current where the diode starts to output a proper laser beam, so 7135 PWM based drivers will work just fine across all levels, but constant current drivers will struggle at currents below the threshold (it works just like a normal LED below the threshold, but very poorly, and it doesn’t damage the diode).

Copper 18350 Convoy S2 with the L70 LED from Kaidomain. I didn’t bypassed the springs, and the convoy driver doesn’t supply much current for it anyways, so it isn’t running at it’s maximum yet. Next step is to bypass the springs and swap the convoy linear driver for a FET driver.

4 Thanks

This driver is a three channel FET+1+8. So 7135 chips , or a single chip, controls the lowest output.

At 31.1A the little X6 showed me the barn at 610 yds but my phone’s camera doesn’t see it.

I could clearly see this house at 432 yds but it barely shows in the pic.

Little light got quite hot very quickly! Lol

3 Thanks

I LIKE that circular die! :grin:

1 Thank

I have another copper S2 with the 5000K 5050 and a FC11 with the 3000K 5050. Surely there’s better options available for throw or color rendering, but these LEDs are so odd and unusual that I’m keeping them. Hopefully these oddities become more popular, and get more options.

1 Thank

Who makes these circular dies?

Do they make the 3000 lumens at 8Amps as claimed?

I don’t know the manufacturer of this LED, and so far I’m limited to 5A due to the driver limitations and not bypassed springs, but i believe that it can get to 3000 lumens. I just don’t believe that it will do it at 8A, maybe at 10A. I will try it direct driven to see it’s full potential.

Eureka! I made a discovery! Lol

Apparently TA remapped Bistro to take advantage of the 8 chip mid section. If the levels are set below the threshold of where the FET starts assisting then Turbo is left out. Only to be found by reversing into specialty modes from Moon ( or low if moon is off )

I set it up with Moon On and 8 levels, now I have 9 evenly spaced modes that rock!

I will get amperage and output readings on all levels tomorrow.

Edit: This is a 22mm Texas Avenger driver offered by Texas Ace and running his modified version of Bistro. I used the then Premium components building this driver, no idea why it was in my parts box, this was likely built some 7 years ago, no memory of it.
