i wonder if this real 1900 lumens… or maybe someone could do some magic with this thing
a lot of room for DIY

Don’t know about initial lumens, but it might not be able to hold 1900 lumens for long even if it is well driven - look at the mass and surface area of it, it’s tiny.
Insufficient heat management = loss in efficiency and brightness <— this actually occurs in probably 85% of lights, but would be more prominent in this one.
Also, this will not throw very far. Even at 2000 lumens, it would have around 20kcd (around 5 times less than a K40 or TN31). Due to the small and shallow reflectors which merge it has a small surface area, thus resulting in minimal throw.
You wouldn’t want a bicycle light that favours throw over flood though, unless you’re riding on roads maybe.
Daylighter, this is basically your Sky Ray S6 in a different package. Probably 1500 lumens max, maybe 1800 if it's driven harder. The limitation is again the battery pack. I don't believe their claim of a 6600mAh pack at this price point and you are probably going to wind up with the same limited run time. Notice that all these 3 XM-L lights have the same descriptions? None list run time specs. At least on e-bay, that's so you can't call them out on not living up to their claims and demanding a refund. These are now popping up all over, but basically are a poor design, so you're starting to see price drops and inflated claims in an attempt to move them. Avoid - there are too many other good choices out there.
shoot… wrong link…
i meant this one…

massive reflector
That light is less throw, more flood, a well driven C8 ought to throw further.
If it's anything like the S6 or other 3 XML bike lights, it won't throw far. Not nearly as far as a HD2010.
Also, if it's like the S6, modding might not be possible. I can't remove the reflector or pill in mine.
But neither are practical.
Cool thy lumen lust, friend! It shall get thee into much and diverse purchases! 
too late for that… never ending quest for the perfect flashlight already cost me almost $400 this week alone
just got e mail from ebay… i just won this hid flashlight :bigsmile:
hid flashlight 45/65/86 watts for $108/ free shipping
actually i was just bidding high enough but less than buy now price… i got lucky
The 8” lantern is overpriced. Personally I’d get this one, 9” reflector, and make a lipo battery pack to run it.
I don’t think you could get a more powerful thrower. Sometimes you do see them on sale for cheaper too. I’ve seen lit for $179.99 with free shipping before.
