For the money I think you could do better. Your basically getting 2 x 70w lights, and the colors are not going to mix completely. Under the blue is going to be blue, and under the white is going to be white. I'd say spend another $50 and get 2 x 120w led
fixtures with 55x3w LEDs.
I have a 10w one of these flood lights and it seems weak. I have used 10w emitters on a DIY light and I know they were powered at 10w. I bought this single 10w flood light and it is dimmer than the ones I made. So it may be a 10w led
, but it may be underpowered.
They would work, but I think they would be better suited for supplemental lighting instead of your main light.
