I didn't see any specifications. I would want to know the dimensions of the light and the lens angle. From that, you can somewhat determine the area it will cover. Sometimes LED lights have specs that tell you the designed coverage area in both X and Y directions and what height it needs to be. This is important to know as to whether or not it will work with your grow bed.

Narrower beam angles work best for tall plants, up to a point, than do wide angle lenses. From my rather expensive experience with LEDs, they don't buy you any power savings if all you are growing is leafy greens. Too much red light and too little blue is just a waste of electricity and cost for leafy greens. With some of the left over LED lights we have we are planning on using them for sprouting of leafy greens.
