The price seems very good for what it is. Too good to be true? Depends on why so low, but it is not out of the realm of possibility, to produce 5500 lumens with something this size to provide adequate heatsinking... just a series of LEDs, if not a high end, more expensive brand so you can stay at a low price.
Today it is not hard to achieve a little over 100 lumens per watt which is what they're specifying. At the same time it could be the same shenanigans where they use enough LEDs to produce that lumen value if they were running at full rated power but don't run them that high to make the heatsink design less expensive.
Either way, I bet it's significantly more than $14 worth of light, then lifespan is the harder part to estimate since these designs change so often that you're not going to find a review several years old that's applicable to a few generations later product sold by the time the reviews are old enough to mean anything about lifespan.
I'd get one to try it out, but the local store is out of stock and don't see a shipping option right now.
