LM301B boards right? I'm using the same diodes, albeit on a much smaller scale in a handful of Q-series strips, and despite being too inexperienced to offer much in the way of comparisons I've been very happy with them so far in terms of how little heat they produce and light performance.
Worth noting they don't seem to have any supplementary spectrum on there - not the end of the world as you can always add separately and tailor your requirements, or simply not bother of course.
