I like the idea of the 12 volts for possible solar power, has anyone tried them? Reviews seem good

I'm thinking of using them in a tote for vegging....

Or maybe this spool for 13.88

Or would i be better off using the colored lights?

Not worth it, I think the UFO's are pretty cheap and give a nice output...

I also seen some LED bulbs at HD yesterday that was pretty interesting but pricy if you had to use 10 bulbs to get the lumens you desired.
