2020年1月25日 · Today I received one of the scarcely available Luminus SBT-90.2 leds from nealsgadgets, and tested it for voltage and output. It is a single die 3V led with a large die area (3x3mm) that combines high output with high luminance, which makes high output and far throwing flashlights possible. Luminus is slow with datasheets, I do not think there is one yet for the gen2 version. Edit: JaredM ...

2021年2月6日 · So small light can’t dissipate heat of SBT-90.2. Don’t bother. Mike. The same could be said of the lumintop X9L, KR1vn90, Amutorch XT45 but those lights are still a lot of fun! This light looks interesting to me. nice form with TIR.

2025年3月10日 · LED short test / short review EN Luminus SBT-90.2 2025-03-10 Type: single die, lateral Bin: — Color group: — (6500 K) CRI: 70 The emitter tested here was provided to me by TLF user @Flup.88. He purchased it from Convoy some time ago. Many thanks for this at this point! Compared to the previously tested SFT-90, the design is very different. The 11x10 mm package consists of a dark green ...

2021年4月19日 · Listing just says SBT-90, not SBT-90.2. Even the datasheet specs included are for the old SBT-90, looks like to me. I sure wouldn’t trust a listing like that if it’s a SBT-90.2 you are looking for. Can’t imagine anyone interested in the old gen of this LED. What does the 2nd generation sell for, $20 or $40?

2021年5月16日 · The TN42 V2 is using the Luminus SBT 90.2 LED in 5700k with a CRI of 70. This LED is 3V on a single die with a large physical size. It combines high output with high lumens which makes for very high output and far throwing flashlights and in …

2025年3月8日 · The beam is perfectly fine. There is virtually no difference between SFT-90 and SBT-90.2, which is why a beamshot of an Emisar D1 with SBT-90.2 is shown here. Depending on the reflector geometry and focus, a minimal yellowish corona may be present. This effect is more pronounced with the SBT-90.2 due to reflections on the outer frame on the ...

2022年1月19日 · I know there’s a list of white sbt 90.2 flashlights, but which ones are available in red? Also, is it possible to mod a 90.2 red into a 90.2 white light? If so, which would make the best jacket-pocket carryable or smaller host to use for an sbt 90.2 red project? I realize that sbt 90.2’s do not usually conform to edc-sized hosts, so some …

2009年11月2日 · Looking at Vinh's stats of the stock Acebeam K75 he tests 4,800 Lumens and 1.55 million cd with a 5" head. I'd like both a smaller light also with a floodier beam (though still in the thrower category) and was wondering if a 2.5"-3" head size could get #'s close to 4,000 lumens and 5-800Kcd...

2023年9月14日 · I’m more interested in what actually defines the difference between a 5000 lumens XHP70.3 and a 5000 lumens SBT-90.2. Is the difference in throw/flood solely decided by the LES? in very rough estimation a XHP70.3 will need around 6V 8A for 5K lumens, and an SBT90.2 will need 3V >20A. What makes this difference in efficiency?
