The LED's are being sold as grow lights? If so I say should be great I grew up with my dad using LED's for everything possible because they use so little energy. ON the other hand he always explained that hey could used in many more ways because the color of the LED depends on the amount of electricity going through, and the diode. Theoretically this should mean that he light spectrum emitted should be great for plants. I have been thinking about this for a while so I would love to know how it works for you. As far as the color goes the red and blue are the ares on the color spectrum used by plants most. The only drawback that I could think of is that without the full light spectrum of a white bulb you won't have any yellow or green which is what the human eye sees most. The look might be very different. I have a grow shop in town here and will go by and see if they have any of them and can explain how they are used in hydroponics.
