Luminus SFT40 test

Dang, that's nice!

Damn, you guys are good haha. Very interesting stuff! Freeman- did you just design a BLF GT 3 volt board for this ??? Lol.

Yeah, but it didn’t take me too long, I just placed the components quickly, it’s pretty easy since there is a lot of space, I used 46mm but I’m not even sure what the actual size is ?

Something even better would be a buck driver, especially since the original carrier is 4S ? For high efficiency and full current for the whole battery range, but that’s more complicated of course.

46 mm is about perfect! I measured 45.6 mm for TA's driver for the GT90, and 45.75 mm for the TA MT09R driver and both fit loosely, so 46 mm is actually better.

The GT drivers has a big (wide) brass button while the MT09R driver has a spring. As long as you have a wide enough pad on the spring side, the brass button can be transferred.

I put a 12mm batt+ pad and the GND ring is 4mm wide, are these sizes okay ?
I can put it up on OshPark, though you’ll have to wait for Gchart’s DAC implementation.

You got the dims exactly matching - the 12 mm batt+ pad and the 4 mm GND ring - matches the TA GT90 driver perfectly. The MT09R driver is also 12 mm batt+ pad and a 3.5 mm GND ring.

Not to derail this fellas, but just stumbled across this…

5050 3.14mm² assuming 2mm Ø “30W”

Nice it's available in 5000K and with a round surface - would that be like perfect for an aspheric? Hhhmmmmm. $11 qty 2 shipped.

Sounds too good to be true, but I bought two. Did you get them as well?

I ordered 2 bare and 1 mounted on a 20 mm 2 mm copper MCPCB.

They say 3000 lumens. :open_mouth:

JaredM, that led looks Great! i think, how does the round phosphor work? it says 8000ma max output? thats great! and 5000k?

Are these only good for aspherics?

Size comparison with the SFT40 and a CSLPM1

Should be pretty interesting if it meets its specifications.

I ordered two on 5000k

My order got canceled. Listing has changed to a new product. :cry:

EDIT: There is something weird about the mobile version of the site. I’ll try clearing cache and what not and see if that changes anything, but the desktop version of the site still has the emitter listed. Ordered again, this time w/o a mcpcb. Fingers crossed!

I still see it here: https://www.aliexpress.com/item/1005003246180028.html?spm=a2g0s.12269583.0.0.1922f481t1weW1

My order not cancelled... yet

Previous post updated. Mobile site issue

djozz, I just noticed that you have yet to add this test to your directory thread linked in your signature. Thanks again for all these years of work, BLF wouldn’t be the same without you! :beer:

SFT40 is 5050

Sadly, out of stock.
I’ll be using TA FET+1+15 for my GT->90, which works because I don’t need 9A regulated. Suppose you could stack 7135s…

Thanks :beer:
And added.
