I used the led modules like the ones @MD389 used. Best thing is they fit to existing screw holes. But I guess if you have leftover other pixels they'll work too, you just might have more obvious "hot spots".
I have noticed that my balls have gone a bit orangey/brown after 6+ months in the sun, but doesn't effect brightness or colour at night.
has anyone couple spare of these ? I'm trying to do an outline of the driveway with them and I think I'm going to be about 2 short , although I'll take more if if you have them for spares , willing to paying postage etc
I just had to go buy a set. Also got a bunch of tinsel and bows for $0.25 each !
The pack contains what appears to be 4 of the same type of solar balls as the single ones. It also has 4 wall mount brackets. The spacing between the mounting holes in the base of the ball is 47.5mm approx.
