Why not consider merely a lightweight flash? I find the LEDs compelling only if you wish to shoot video (difficult to do in macro because of the narrow DOF). For macro stills, flash is preferable because flash durations used in macro photography are so small that it solves the whole issue of camera shake and allows hand-held macro shots with complete confidence. Moreover, one flash is all you need, à la John Shaw. Two flashes (or LED lights) inevitably lead to dual catchlights in the eyes. It's also lighter and easier to handle to have just one flash dangling in front of one's camera.
