It says that the multicolor has 47 blue, 77 red, 77 orange, and 24 white. The blue/red has 60 blue and 165 red. The multicolor is cheaper than the red/blue. I'm just trying to figure out which one to get, the multicolor or blue/red.
I found the different spectrum charts, and they really doesn't seem to show much difference between multicolor and blue/red other than the multi having a little more blue and a small amount of green/yellow/orange, however they are significantly different than the white which a decent amount of green/yellow/red. Also if it matters to you, the b/r claims an 18w draw while the multicolor is rated at 27.5w. What I can't tell you is what that means for the plants. The weed people have that down to a science, but I haven't spent much time looking at their stuff. Also, I don't know how much this may even matter to you now though since white is back in stock and every color is the same price other than multicolor being very slightly cheaper.
Anyway, my non-expert conclusion is that the multicolor would likely be fine, especially after I saw the blue/white had basically nothing outside of a peak at blue, but that comes at the cost of slightly more energy usage and the purple color that can make it hard to accurately observe your plants. Also, I included a chart on blue/red lighting from carnivorousplants.org
which might be helpful.
