Wait, is this a question on a product, or an advertisement? I believe the rules state that advertising a product is not allowed.
Since he's posted no links, brand or model names - just a small selection of technical data - I don't see how it could possibly be considered an advertisement. :thinking:
Something of a vague question though - to make anything approaching an accurate comparison you'd have to take lux readings from the OP's light and it's nearest competitors at a fixed distance, in the same conditions (i.e. on the same night) and using the same lux meter. And even then it comes down to how you perceive "brightness" - a tightly-focused light could give a higher lux reading than a more floody model even if the tightly-focused one produces fewer actual lumens, if you get my drift?
The beam from my $3, 5mW laser pointer is much "brighter" at 200 metres than that from my car's 55-watt halogen headlights, but the tiny spot of light from the laser is no use at all for illuminating anything.
