Sft-40

The SSTW series are high brightness white Sft-40 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 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. I described the method in detail in my XP-L test, with two minor upgrades since that should not matter significantly for the results: I used my Integrating sphere no.

And it outperforms the SST40 when going over 7A, sft-40, so thermally it must be better.

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.

The datasheet: SFT40datasheet. SFT40 Emitter - What's so great about it? I described the method in detail in my XP-L test, with two minor upgrades since that should not matter significantly for the results: I used my Integrating sphere no. Wow, I was not expecting that boost in output at A! Thanks for what you do djozz. 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. Power Semiconductors. Much better than expected! 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. Very valuable info! Compact 10 x 11 mm2 isolated surface mount package. Sweet spot around 8 Amps? Conclusion: great led for throwy direct drive flashlights, best luminance of all 2x2mm dies I think. Thank you for the test, looks to be well made by Luminus.

SFT70 just got more exciting, but this should entertain for a bit until that shows up. Same as the SST40? Here is underexposed to see the hotspot shape well beam from a smooth reflector, projected on the ceiling. 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. Thx djozz for the test. EasyB EasyB June 29, , pm What did you mod today? Should go toe to toe with 2mm Osrams if you can drive it to A. Contact Us. Power Semiconductors.
