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 efficacy and high lumen 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 M21 series continues to become increasingly complex, with M21A through M21F available — each having different reflector sizes, button configurations, and options for emitters. Nothing fancy here, just the light, and a subtle nudge to just go out and use it. The only other thing that could have been put in the box to round it out would be a USB-C to USB-A cable for charging, for the cable hoarders out there like me. This makes it a lot more comfortable when carrying for longer periods. The M21F comes with a lovely slate blue anodisation in a satin finish, with a bright blue bezel around the button. The knurling on the body tube is more grippy than it appears ; with the lined ridges, I had assumed that it would be fairly smooth, but it grabs quite well.

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.

EasyB EasyB June 29, , pm Wow, I was not expecting that boost in output at A! Great results, Djozz! Driving a Cree XHP Ecosystem Binning and Labeling Datasheet. Although the led was not even well centered, the beam looks very smooth, with no tint shifts. Just like the SST Color LEDs. Luminus Advantage. Limited time only! Lumeniac Burgerman June 29, , pm This appears to not just surpass that, but also be more convenient as a 3v led.

The Luminus SFT has been on the market for some time now.

Thank you for the test, looks to be well made by Luminus. Application Notes. And it outperforms the SST40 when going over 7A, so thermally it must be better. They are targeted towards the most demanding specialty applications where high directionality and uniformity are critical. Th Th June 29, , pm I'd planned on 6A but I may pause and order a different driver now. Those should throw a bit further, though with smaller hotspot and less output. I added the graphs from two earlier led tests that I thought relevant in the chart, for comparison. Yep, Convoy rightly chose to drive this led at 8A. Here is one that needed testing because I want to use it in a mod. Maybe lm if it was a domed version of this?
