Sft-40

The SSTW series sft-40 high brightness white LED suitable for operation up to 10W that excel sft-40 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, sft-40. They are targeted towards the most demanding specialty applications where high directionality and uniformity are critical, 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.

I could not kill the led even at 20A, which is the limit of my power supply, sft-40. Luminus Advantage. What would you pick for a sft-40 range thrower?

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. TG, XHP

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.

Large, monolithic chip with uniform emitting area ideal for directional, long throw applications High thermal conductivity package - junction to case thermal resistance of only 0. JaredM JaredM June 30, , am What would you pick for a mid range thrower? Thanks for all the work and time you put into these tests, djozz! Application Notes. I, and for the current I used a clamp meter, which appears to measure 0. Design Files. Ecosystem Solutions. They are targeted towards the most demanding specialty applications where high directionality and uniformity are critical. Specialty White LEDs. Their monolithic emitted is perfect for directional specialty applications requiring a combination of high efficacy and high lumen output. Ecosystem Datasheet. I added the graphs from two earlier led tests that I thought relevant in the chart, for comparison.

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 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. DTales DTales June 29, , pm 4. Agro Agro June 29, , pm 3. Thanks for testing djozz. Correllux Correllux June 30, , am I could not kill the led even at 20A, which is the limit of my power supply. They are targeted towards the most demanding specialty applications where high directionality and uniformity are critical. Yep, Convoy rightly chose to drive this led at 8A. Maybe lm if it was a domed version of this? I, and for the current I used a clamp meter, which appears to measure 0. Their monolithic emitted is perfect for directional specialty applications requiring a combination of high efficacy and high lumen output.
