I’m interested, but I really want 2200K/3000K for my LT1.
I’m checking in with BelMORDOR to see if anything warmer than 2700K would be possible. He said 2250K isn’t possible but I’m checking if that’s an absolute no.
Edit: seems like 2700K will be the lowest cct available.

ok. Just LampMan
s. BelMORDOR it is BELARUS. Based on this picture

sorry, only 2700k. You can get ~2600k by using poorly transparent diffuser
If you worry about blue, so
This topic was discussed earlier in the hundreds of LT1 pages but I don’t believe it ever came to fruition *BLF LT1 Lantern Project) (updated Nov,17,2020) - #11099 by iamlucky13
Of course. Let’s see how much interest there is first. If there’s enough interest for you to think it’s worth making, then we can get into the specifics of everything. I don’t have a pair of calipers around me at the moment so I don’t want to rely on myself to get the +/-0.5mm correct measurement.

even if you are alone, I will draw it for 100$
after that I can order PCBs and stencil
Price :money_mouth_face:
In this time (cose you payed for prototyping) pcb will cost the same price with factory ~1$
ordinary price is 2.5$ for Ø65x2mm плата для 15-60шт SunLike SOL 2835 Ø65x2mm 2oz 4P15S
so
1+1.5(soldering)+32x0.3=12.1$+shipping

I might be ineterested in a 16+16 2700k / 5600K but that’s if it’s the actual whole light. As for just the board itself, it depends if I can get someone to fit it for me. How much better will the tint be compared to the original? The LH531Ds are not know for being rosy so I’m guessing these will look a lot better.
Tint wise, I don’t actually know. Come to think of it, I have no problems with the current LT1 tint. This would help reduce the harshness of having just 4 LEDs.
From speaking to Barry at sofirn, I don’t think sofirn would be willing to do it. They seem to care more about the scale of things compared to Hank or Simon who will custom make anything. Barry is always talking about workers being too busy at the factory.

With this picture Ø is 63mm and 29.5mm between holes and 6.5mm middle hole
I sent a message to DBSAR to see if we can get the exact measurements of the LT1 board. How did you come to those measurements? Did you read them somewhere or did you look at the photograph and estimate it out?

it was easy :disguised_face:
I know that size of the leds is 3.5mm :student:

The sizes came from me, as quoted from the LT1 thread:
djozz:
I have a request for someone who has experience and is willing to do circuit board drawings and upload it to Oshpark (as I can not do that)
Here is the LT1 ledboard:
*Outer diameter=60mm
*Central hole=6.3 mm
*Screw holes are 2.8mm (for M2.5 screws) and are 20mm from the middle (or 28mm from each other).
*center of the anti-rotation holes for the plastic cup are 8.5mm from the middle and are 2mmx4mm width/length.
The request is to draw a commonly from Oshpark orderable frp replacement ledboard for 2x20 standard 3030-size midpower leds, so 20xwarm and 20xcool. If the warm and cool leds can be mixed well (as far as the traces allow), the tint mixing of the lantern will profit.
As the midpower leds will receive 100mA per led, I’m pretty sure a metal core board is not needed if you order the board in thin 0.8mm frp and perhaps choose the thicker copper tracing. The board can, like the stock board, be screwed down with some thermal paste in between.
This makes the LT1 suitable for the entire range of available standard midpower leds, including Optisolis, SunLike, and all the others.
Of course if someone dares to have real MCPCB’s for 3030 leds made and sold, that would even be better. But it all starts with the design.
And I sure am in for one of these boards, but the value would be much better for me if it had the combination of 5000K and 2250K Sunlike leds.

so… it is not samsung LH351D what is 3535 size
if 28mm from each other, it is 19.8mm from the center…

I would also prefer somewhere around 2000k + 5000k if at all possible
