What did you mod today?

It should be quite the same range as before the swap. Nothing to be ashamed of anyway.

Updated one of my very first builds, on one of my favourite hosts still, the DongDongHai DDH-D2G


Upgraded to Convoy 8A buck driver and SFT40 3000K high-CRI


3KK on the left, 6500K on the right.

Lumens loss is noticeable, but still sufficient for practical use. And the trade-off isn’t that bad in exchange for quite nice colour and CRI.

And this is where individual taste speaks out. I’m happy you like this 3000K which means it suits your taste. For me the 3000K looks creepy like ā€˜hell mode’ while the ā€˜pure white’ looks optimistic like noon in the summer :wink:

It’s more likely because my camera is !@#$ and doesn’t do night shots well. It looks way better irl. I had to shoot this at 12800 ISO and that screws the colours up all the way to !@#$. 3000K is a warm soft comforting glow in person.

OTOH I never really had a problem with 6500K. I have many lights with it and will continue to use it.

But isn’t it nice we have options?

This way or another I’m familiar with 3000K. It happened to me to buy it a few times.

The funny thing is yet 2 years ago I was a great fan of 4000K and hated cold light. But just considering why 3000K is too warm to my taste i realised the warmer the temperature the more scary look enlightened things.
Outside it felt like in the Sun after the atmosphere catastrophe (like dark ages after the meteorite hit) while indoors it gave feeling like holding a medieval fire torch to light up catacombs.
Then my transformation started and led me to the conclusion the cooler the better.

But as you said: that’s very good various people like various light. However I believe the taste may change over the years.

Did you really just imply that people might ā€œgrow outā€ of liking warm light? What an odd thought to have. Hah! No offense intended. Maybe you’re right. Personally I doubt it.

None taken.

No, ā€˜growing out of’ would mean this is one direction process predictive over time which I don’t think it is.
I mean rather that tastes change. In random direction and after random period of time. At least when it comes to light parameters I think so.

Same thing happened to me. Well, I didn’t hate 6000K+. I’m using it more on the exterior of my place and if I’m using a thrower or driving, I really prefer colder.

If I’m trying to locate something important I prefer natural 5000k. I don’t think this will ever change. Otherwise warmer colors all the way. I prefer getting dazzled by warmer headlights of oncoming traffic. I’m sadden to see parks and walkways go the cooler route, for freeways it’s understandable.

That looks great. How do you like the IF23?

Just a simple 519a 4500K DeDome:

before, 4400K, duv 0.0038
after 3500K, duv -0.0023:

dedoming dropped the CCT by 20%, and lowered the duv by 0.0061

@jon_slider
So you just ā€˜pushed’ the dome off?

Yes :wink:
I ran the light on high for 10 seconds first.
Then carefully pushed on the side of the dome. It came off entirely in one piece. Leaving the totally clean glass exposed.

519a is the only LED Ive seen w a glass layer under the dome. It protects the phosphor and makes dedoming possible.

Today I played with Noctigon M44. Swapped some sense resistors for 3,2A@24V times 2.

3 Thanks

If I get one I’ll do that mod, can you post what values you used and which resistors they are?

Up there next to screw hole with R09’s written on them. It’s 15mOhm piggybacked with 90mOhm for both channels, which by my stock driver measurements should have been 3A out, but ended up being 3.2A. I think clamp meter inaccuracies might be the culprit. I measured stock output to be 1,94A per channel.

1 Thank

Thanks, also what size are they? Gonna order some and I’m not too familiar with SMD components.

1 Thank

1206 size. If ordering some, might as well order 13mOhm ones. Then there’s no need for biggybacking. I just used what I had and therefore had to stack them.

1 Thank

Having trouble finding them on Aliexpress, but they’re available on Mouser at least. I guess I’ll just have to pay for the expensive shipping.
