Sharmman Actuallymine was defective and refunded 'cause one led's copper strip caused short circuit with flashlight body in a while , so I really don't know if my review is representative for good working batch of this flashlight ...

-- SST-40 version 5000K -- Measured 8,6A max using the highest drain 21700 Samsung 30T (2,15A per SST-40) and found 4000Lm max with 44KCd at cold start and 9° flood angle (Note that 7000Lm require at least 16A current draw of 4 x SST-40 in parallel). If a single SFT-40 & reflector had been used at same current flashlight would had exceed 150KCd. 7135+direct mosfet (WMB023N03 of 4mR RDs(on)) topology

Sharmman @CaptnKnuspa Thisled has low efficiency and requires 50A at 3,5V and 14AWG wiring in order to reach 9000Lm , there is no single Li-Ion battery that can provide 50A and maintain output voltage >3V. The best solution is only Samsung 30T for a few minutes.

I am a little disappointed about this light. The light has an orange-peel reflector (it doesn't work well with a smooth reflector, I tested it and got a significantly dimmed center). The throw is much less than my XHP50.2, SST40 and SBT90.2 FT03s. The lumen output seems to be much lower than the claimed 9300lm - I think the required current for 9300lm is limited by the batteries (I tested with Shokli

Sharmman Correction: 6800 Lumen for this SBT90.2 flux , my own SBT90.2 UB flux provides 7500 Lumen at 39A

Sharmman 19/01/2021

A real 150W SBT90.2 thrower that was measured 19.3A at 8.4V. Driver works at 2SX2 Li-Ion 8.4V using 3 parallel buck drivers topology of 13A output each that provides SBT90.2 almost 40A at its over-current limits and the only flashlight at this size with single SBT90.2 that can really exceed 7800 Lumen at cold start. Max beam light density at 5m was measured around 670Kcd (at 10m maybe closer to 750KCd

Sharmman @ALEXAND Idon't know , maybe , the solution for me as an electric engineer is to use higher VF voltage binning Luminus SST-40 !

Sharmman 31/05/2019

Although this flashlight is stated as 2400Lm and 190Kcd , this latest SST-40 has very low Vfd and the cheap method that driver works in turbo mode where low RDSon mosfet is DC connecting led directly to battery , can be fatal for Led's life ! Using a real 20A discharge 26650 Li-Ion battery and as expected in turbo mode led's current was over 9A at real 4V of battery , led's luminance was about 3000

Sharmman DearBanggood , I never said that I have any problem , I just purchased that in the lowest cost that money can buy such a PSU , in order to improve it as it fits to my usage !

Sharmman 23/10/2020

Nothing special , just a cheap working SMPS PSU mostly for Leds array power supply. Half bridge topology with capacitor divider so do not belong to hard switching SPMS with lower RF interference but still not suitable for ham radio usage. An 45° C normally opened thermostatic switch is required for fan that is always working.
