Sft-40

The SSTW series are high brightness white LED suitable for operation up to 10W that excel in directional specialty applications requiring a combination of high sft-40 and high lumen output, sft-40.

The Luminus SFT40 is like the dedomed version of the SST40, but it did receive a unique new design with the 4 bond wires that end in cut-off corners of the die. So expected is that bond wire failure is less likely to happen. The datasheet: SFT40datasheet. Here is underexposed to see the hotspot shape well beam from a smooth reflector, projected on the ceiling. Although the led was not even well centered, the beam looks very smooth, with no tint shifts. The tint is plain low CRI cool white, for the record here is tint information, the tint was measured in the middle of the hotspot from a smooth reflector.

Just like the SST The Luminus SFT40 is like the dedomed version of the SST40, sft-40, but it did receive sft-40 unique new design with the 4 bond wires sft-40 end in cut-off corners of the die. Thank you for the test, looks to be well made by Luminus.

The SSTW series are high brightness white LED suitable for operation up to 10W that excel in directional specialty applications requiring a combination of high efficacy and high lumen output. Their monolithic emitted is perfect for directional specialty applications requiring a combination of high efficacy and high lumen output. They are targeted towards the most demanding specialty applications where high directionality and uniformity are critical. Emitting into air with a low-profile window, they are specifically targeted to fiber illumination and light-engines where optical control is critical. They are ideal solid-state light sources to replace high performance lamps including Xenon and HID in a range of medical and industrial applications. Toggle navigation. COB Arrays.

The Luminus SFT has been on the market for some time now. Available only in cool white light color at launch, a warm white variant with high color rendering was also available for a short time, which indeed makes this emitter special, as it combines high luminance with good light quality and warm light color at the same time. The cool white SFT was purchased from Mouser in November , while the warm white SFT was purchased from Kaidomain as far as is known, it was also only available there. The LED chip surrounded by white silicone sits on a gray ceramic substrate and is connected with a total of four bonding wires, making this emitter a classic lateral design. A gold-colored metal frame serves as a perimeter for the white potting compound. This makes this LED very robust, making it easy to handle without having to take special protective precautions. However, care must still be taken to keep the emitter free of dust and particles! On the left side of the following pictures the warm white version is shown, on the right side the cool white one. The emitter is 5. All accessories for XM LEDs can thus be used, and thanks to the symmetrical package, centering aids made by lathe can also be used.

Here is one that needed testing because I want to use it in a mod. The datasheet: SFT40datasheet At 0. Very valuable info! Moreover, when after the 20A going back to 5A and let the led settle for 10 minutes, the led performed exactly the same as before the 20A torture. They are ideal solid-state light sources to replace high performance lamps including Xenon and HID in a range of medical and industrial applications features Extremely high optical output from a 14 mm2 circular source: Up to 4, white lumens Round emitting aperture provides efficient match to circular optical systems and narrow beam spotlights Unencapsulated package preserves small etendue facilitating narrow beam optical system design Integrated COB module ready for opto-mechanical assembly in host fixture Integrated thermistor enables consistent temperature monitoring during operation for high system reliability High thermal conductivity package - junction to heat sink thermal resistance less than 0. And the 4 bondwires did their job! Emitting into air with a low-profile window, they are specifically targeted to fiber illumination and light-engines where optical control is critical. Thx djozz for the test. And it outperforms the SST40 when going over 7A, so thermally it must be better. Impossible to destroy. Development Kits. Conclusion: great led for throwy direct drive flashlights, best luminance of all 2x2mm dies I think. I have a couple on the way from Simon. Although the led was not even well centered, the beam looks very smooth, with no tint shifts. The datasheet: SFT40datasheet.

And although the output performance did not change after the 20A treatment 90W! Wow, I was not expecting that boost in output at A! Yep, Convoy rightly chose to drive this led at 8A.

I've had a pair on the way since June 8th, but I'll have to order more now.
