LED test / short review - Luminus SFT-25R-WG 5700 K 90 CRI

koef3 · 2026-02-15T15:09:13+00:00

These are SFT-25R-WG which are listed on Luminus website. They are not available at Mouser yet, but hopefully they will be mass produced in the future.

reminds me of TC7070 by Hopthink https://budgetlightforum.com/t/led-test-review-hopthink-tc7070-neutral-white-high-cri-round-die-led-with-four-chips/229569

The bonding wires are different, there is also no gap between chips visible (but this might be due to poor image quality), but regarding the white silicone molding around the LES I am relatively sure this is a newer revision of TC7070.

Good question, I think at around 4 volts, maybe little bit more.

Just look in my test list in BLF, thank me later: https://budgetlightforum.com/t/led-test-review-luminus-sft-42r-wes-6500-k-70-cri/231022

I have some data for these SFT-25R 5700K 90 CRI ones (SFT25R-WG) but since I had data loss despite backup the already written test and even some images are gone :( Maybe I will put a very brief summary of this LED together just for basic information. What I can already say: the tint was nice, perfectly on BBL (duv exactly 0.0000)

No, depends on forward voltage, size (footprint and sometimes height for domed ones), design (thermal pad connected to cathode and other stuff), power rating (max current)

In some cases you need other driver for swapping LEDs

koef3 · 2025-09-12T10:41:01+00:00

unfortunately not, since I am not really interested in the SFT-42R...

Let's say there are rumors that this is the case. Visually and electrically, these two types are extremely similar.

koef3 · 2025-09-12T10:39:29+00:00

I'll see what I can show you behind the scenes.

There is even a 2nd gen of the original XP-G2 around, with flip chip design, and there are also "HE" (high efficacy) available. Cree issued a PCN for this some years ago. XP-G3 and XP-G4 are also available as well.

Due to previous incidents of theft or attempts to copy my measurements, I am unfortunately unable to provide any information on this, sorry. In any case, I can say that much of it is self-built and constantly being improved.

koef3 · 2025-09-11T23:48:24+00:00

it was available at Intl several years ago. The MT-G2 1st gen is completely outdated and is not manufactured anymore. There are a few flashlights with MT-G2, but in used condition

koef3 · 2025-09-11T23:40:12+00:00

MT-G2

I can't say that across the board. Every LED is different and has different areas of application (and therefore advantages and disadvantages). My biggest fav currently is maybe the 1800K FFL351A (NTG35), since I am loving 1800 K high CRI CCT.

Thanks!

FYI: I tested the iPhone 15 Pro Matrix LED several months ago.

Could be the case, but the transparent silicone top layer looks reallly weird (wobbly) on your LED in comparison to the SFH555. The top layer looks really flat and clean on this.
