1: The host looks good, the picture that shows the LED’s themselves is questionable on weather they are real cree or not but they very well could be, either way you can count on an cold beam. Although for a bit more I have a modded old school 5X skyray with truly genuine XM-L2’s led’s, FET+1 driver with temperature regulation and makes around 4500 real lumens at turn on vs the ~2000 the skyray from fasttech will most likely do. I actually have 2 of them for sale, 1 of them is dedomed for more throw. Asking $65 for it. /shameless plug. When the Q8 comes out that will be the “skyray” to get for sure.
2: In this case I would cancel it for sure. There are so many better options for that price. Get a convoy L6 for $50 and spend that extra $50 on something else. The L6 will blow that thing away.
As far as how the voltage and multiple LED’s work, this is not correct. More LED’s will be brighter, assuming that nothing else is changed and they are wired in parallel. For example I get around 8500 lumens out of my 7x SRK but around 10k lumens out of my 8x versions. There are some good articles and videos on google that explain forward voltage, LED wiring in series and parallel and all this jazz.
It all boils down to adding more LED’s will generally increase output as long as you are not reaching a bottleneck somewhere else in the system. Also if it is using a regulated driver then the increase will be very small when adding another LED but this is very unlikely in a light like that.
Either way those LED’s almost assuredly fakes and even if not that are very old and I would be surprised if it made more then 3000 lumens as it comes Although I have no idea what is inside that light, it could be better made then I figure.
Although the L6 can make 6000 lumens when modded, is much more comfortable to use, will throw a beam a lot better, better tint and is basically better in every way.
Spend the left over cash on some smaller lights to finish your collection.
My must have lights for everyone include:
Skyray / Q8 style light
Convoy L6 style light
C8 / X6 / pocket thrower style light
Convoy M1 / thorfire VG10 style light
Convoy S2 / S2+ / tube Style light
With these you will have a light for 95% of situations and great hosts for modding later if you want (well except for modern skyrays without a shelf).
The only thing missing is a big thrower but there are not really any good budget options for that at this point unless you are good at modding. The convoy L2 is a reasonably good thrower though, just not enough better then the C8 for most people to “need” it, still a great light though.
