Price per watt/light output you can likely do better at Home Depot and the like due to higher economy of scale.

The spectrum is really more appropriate for greens like lettuce. Even then I'd be mixing in some white light. They are making a completely deceptive claim in stating: Please kindly note that plants do not use the entire spectrum of light. The chlorophyll and carotene only absorb the light at the range of two particular wavelength(blue 400-470nm and red 610-720nm).

I have no idea what sort of LEDs they are using (I would bet on cheap Epistar chips with the LEDs made in Shenzchen which is next to Hong Kong) but they are going to be bottom of the barrel at this price point particularly with their low economy of scale since since LED horticulture lighting is considered a niche industry (it's not generally discussed yet in industry trade journals on LED lighting, for example).

Even at about that price point you can do better with a 120 degree beam angle light more suitable for a bucket (but just by looking at this one I can spot an electrical safety issue):

I would pass on the original light linked to particularly for confined grows like with Space Buckets.
