As an early adopter of LED lighting I have purchased quite a few LED floodlights, this is good as it's a very utilitarian design, produced in great numbers in china therefore the only price difference is based on the LED which only gets marginally bigger as the wattage increases, so no hard work in terms of production ...
A solid metal casing is a pre-requisite as it acts as a heat sink (leds get warm & need air flow, not to be allowed to cook, so a single led is better than a cluster in terms of longevity).
I use a few of these as loft lights, in my larder (where light is more important than looks) & outside for general lighting by the garage, log store etc.
The advantage of colder light compared to "warm yellow light" is increased light output, so if you read any reviews where folk are moaning about cold white light it's because they really haven't a clue as to what they are buying & why!
whiter = brighter, & bright output is what most folk want in reality.
The Lumens output realistically is hard to equate & compare, however this would typically (give or take) be equivilent to roughly 700-800 lumens if the leds are strictly qc'ed & measured (known as BIN leds).
That means you'd get roughly 70w (at a guess) useful light spread over a 120 degree angle, ideal for proper illumination of front doors, steps, shed lighting, basic lighting for a stable or work table etc...
if not sure try looking for a 30-40w model which will offer superb throw of light.
If using outdoors remember to use appropriate connectors.
reminder: A single decent LED tends to be better than a cluster of lower wattage leds, however cost more as they are in less demand resulting in higher costs, as folk get to know more about leds this will change & we'll be more choosey!
